Frequently Asked Questions

Our high-quality activated carbon has a surface area of up to 1500 square meters per gram (competition 1000 square meters). This means that only a few grams of the highly porous material exceed the surface area of a football pitch. Thanks to our special modulation, we have a larger surface area, which prevents the formation of channels and ensures consistent filter quality. With conventional membranes, the filter quality fluctuates or is volatile, which can lead to a significant release of pollutants into the water under extreme conditions. The advantage of our EVOdrink is that it consists of 70% micropores, which have a pore size of less than two nanometers (0.002um). This larger volume of micropores creates more surface area for adsorption. Conventional activated carbon filters have only about 10% micropores. Unlike conventional activated carbon filters, the EVOdrink has a capillary effect, which enables it to filter quickly and efficiently by adsorption. Conventional activated carbon filters would not provide sufficient contact time or would restrict the flow too much to be useful. There are many products on the market that are prone to channeling. These clog the filter and consequently the effectiveness is significantly reduced. We attach great importance to sustainability. Our filter therefore prevents channel formation, which increases the service life of our system up to tenfold. 10-15 times higher adsorption rate 10-100 times higher mass transfer coefficient 10-15 times the amount of impurities removed at the same flow rate The practical test quickly showed that we obviously have an improved chlorine removal rate than conventional activated carbon. Even after 5,000 liters, we were at over 98% and conventional activated carbon filters at 80%. Our iodine value, the most basic parameter for characterizing activated carbon performance, is 1,800 mg/g. Competitor products are at a maximum of 1,200mg/g! Fact: One gram of our material has an adsorption surface the size of a football pitch.

No. Because the minerals remain in the water. Only the pollutants are successfully filtered out of the water. Only phosphates, fluorides and nitrates cannot be filtered because the molecules are smaller. Watch out for ionizers that energize the water. It's like sticking your finger in a socket when you're sick in the hope that the virus will die.

• The EVODrink filter must be replaced once a year. Costs 139CHF.
• The EVODrink is guaranteed for five years.

No, the EVOdrink can be conveniently connected to the cold water pipe.

No, the EVOdrink does not generate waste water and does not require electricity.

Konventionelle Aktivkohle wird über Extrusion Kompressionsformung hergestellt. Beide Verfahren nutzen granulierte, respektive pulverartige Aktivkohle und kreieren mittels Bindemittel (Kunststoff-Leime oder ähnliches) einen spezifischen Blockfilter. Unsere «Aktivkohle» wird im Nassspinnverfahren auf membranartigen Fasern, wie beispielsweise Rayon karbonisiert, aktiviert und letztendlich gesponnen. Angesichts dessen können wir brillante Ergebnisse zur inneren Oberfläche (m2/g) gegenüber konventionellen Aktivkohlefiltern erzielen. Vor allem basieren unsere Kartuschen überwiegend aus Mikroporen mit einem Durchmesser von <2 Nanometer. Konventionelle Aktivkohle basiert vorwiegend aus Meso- und Makroporen welche eklatant grösser sind (10-50 Nanometer & >50 Nanometer).

EVOdrink meets the applicable legal requirements for materials that come into contact with drinking water and food. The components used are RoHS-compliant and meet the relevant FDA requirements as well as the European MOCA regulations for materials that come into contact with food and drinking water.

The filtration performance of EVOdrink has also been tested in independent laboratory tests. Test reports from internationally recognized testing institutes such as SGS document the performance of the filter technology under defined test conditions.

Our "activated carbon" is carbonized, activated and finally spun on membrane-like fibres such as rayon using the wet spinning process. In view of this, we can achieve brilliant results for the inner surface area (m²/g) compared to conventional activated carbon filters. Above all, our cartridges are predominantly based on micropores with a diameter of ≤2 nanometers. Conventional activated carbon is mainly based on meso- and macropores, which are significantly larger (10-50 nanometers & ≥50 nanometers). In other words, the Evodrink filters at 0.002 micrometers and conventional activated carbon filters at 0.1 micrometers.

In fact, Orbital Osmosis is a comparable technology. The technology is patented and even the name is a protected term. However, it differs from conventional reverse osmosis systems in many respects.

Comparison with reverse osmosis

Orbital osmosis also works with a membrane filter in the nano range, similar to reverse osmosis. However, there are significant differences in terms of efficiency, hygiene, water consumption and energy requirements.

Reverse osmosis is considered the most complex filtration method on the market. Water is pressed at high pressure through a membrane that only allows water molecules to pass through. Pollutants such as nitrate, phosphate, heavy metals, chemical residues from agriculture and drug residues are removed.

A major disadvantage of reverse osmosis is the high water consumption: around three liters of tap water are required for one liter of filtered water. In addition, the membrane must be cleaned regularly and changed frequently, which increases maintenance costs and shortens the service life.

Advantages of Evodrop's orbital osmosis technology

Evodrop's patented membrane has been proven to filter all pollutants out of the water. This performance has been confirmed by two independent, accredited Swiss laboratories. Only one liter of tap water is needed to obtain one liter of pure water.

In addition, the membrane is particularly durable: it only needs to be replaced after 10,000 liters or after five years at the latest. With a daily consumption of six liters of drinking water, this corresponds to a replacement period of around four and a half years.

In addition, Evodrop uses food-safe, NSF-certified hoses in its drinking water filters that meet the highest standards of medical technology - the same hoses that are also used for infusions.

Superior filtration depth

The Evodrop system filters pollutants down to a size of 0.0055 micrometers from the water. By comparison, ionizers only reach 0.1 micrometres. This means that water that has been treated with ionizers still contains numerous pollutants.

Tap water is often advertised with superlatives as the "best controlled food" in Germany. However, this statement is misleading, as the Regional Court of Hanover found in December 2020 (judgment 18 O 178/19 of 07.12.2020). The court prohibited the advertising with this reference, as it is an unlawful advertising claim.

Court judgment

According to the court, the statement suggests absolute certainty, which is not the case in practice. Water suppliers only guarantee quality up to the house connection. From there onwards, domestic pipes, stagnant water, aerators or other factors can affect the water quality. Contamination cannot be completely ruled out in the public network either.

The court came to the conclusion: "From a strict point of view, tap water is actually no longer controlled at all at the point at which it legally becomes a foodstuff (at the point of use)."

Test results, for example from Stiftung Warentest, cannot support the advertising claim either. They only test whether tap water meets the requirements of the Drinking Water Ordinance - not whether it is checked more closely or more frequently than other foods.

Number of checks is not a quality feature

The high number of tap water inspections is often cited as a sign of quality. In fact, they are a necessity, as tap water usually has to be treated. Mineral water, on the other hand, comes from protected underground deposits and is characterized by its original purity.

Different sets of rules

The Drinking Water Ordinance applies to tap water, while the Mineral and Table Water Ordinance (MTVO) applies to mineral water. While tap water has to undergo many checks as it comes from groundwater and surface water, the focus for mineral water is on maintaining its original purity. Mineral springs are obliged to use an HACCP quality assurance system and to check important parameters daily or even several times per shift. In addition, 26 legally defined limit and orientation values apply to all mineral springs. If these are permanently undercut, mineral water receives official recognition - unique among foodstuffs.

Limit values in comparison

The legal requirements for tap water and mineral water are similarly strict in terms of health, but differ in detail. In the case of tap water, the limit values are not only based on health considerations, but also on technical reasons - for example, to prevent corrosion in the pipe network or damage to household appliances. Calcium is sometimes removed in order to regulate water hardness. Such interventions are not permitted for mineral water.

Conclusion

Food in Germany is strictly controlled. Consumers can rely on its safety. However, the claim that tap water is the "best controlled food" remains an advertising slogan - not a fact.

Limited controls

Only around 50 foreign and harmful substances are tested in our tap water. The oft-repeated claim that tap water is the "best controlled food" is not true. Samples are taken at the waterworks - not at the tap, where the water is actually used.

The Hanover Regional Court ruled in 2020 (18 O 178/19) that this advertising claim is misleading. It suggests a level of safety that is not guaranteed in practice. From the house connection onwards, pipes, aerators or stagnant water can impair the quality.

Unknown pollutants

Many substances such as microplastics and nanoplastics are not even tested as there are no limit values. Substances such as microplastics or aluminum can enter the body and cause damage. In total, there are over 3000 possible contaminants in water. As the chemicals used in agriculture or industry are not always disclosed, laboratories are often in the dark.

In medicine, too, new active substances are added every year - from antibiotics to chemotherapies. Sewage treatment plants can hardly break these down, as purification is based on microorganisms that naturally cannot develop resistance to antibiotics.

Questionable limit values

Even with tested substances, limit values are exceeded - often with the claim that this is "harmless". In fact, limit values are regularly revised upwards. However, studies show that even low concentrations can have health consequences, for example in the case of nitrate.

Further loads

Additional inputs come from industry and construction, whose chemicals are hardly traceable. The so-called "last meters" in the pipe system also harbour risks: Lead, copper or cement can get into the water. Studies in Switzerland have also shown increased uranium levels in regions with uranium-bearing rock.

In addition, pollutants enter the water through the air, floods or old contaminated sites - such as remnants from industrialization or nuclear waste disposal.

Conclusion

Today we live in a world full of pollution. There are plenty of pollutants in the air and food anyway. This makes it all the more sensible to consume water - our most important means of transportation and cleaning - as cleanly as possible. Because if you don't filter the water, you are the filter.

Mineral water is often seen as a high-quality alternative to tap water, but there are important aspects to consider:

1. Regulatory requirements:
   The Mineral Water Ordinance only regulates around 20 limit values, which is less than the regulations for tap water. Tap water is subject to stricter controls in terms of safety and quality.
2. Packaging and environmental impact:
   Many mineral waters are bottled in plastic bottles, which can contribute to environmental pollution. In addition, substances such as microplastics or plasticizers can get into the water. Although glass bottles are an alternative, they have a higher CO₂ impact due to the manufacturing and transportation process if they are not reused often enough.
3. Practical aspects:
   Using a filter system such as EVOfilter can make everyday life easier, as you no longer have to buy or carry heavy water bottles. You also have access to filtered water straight from the tap at all times.
4. Flexibility and costs:
   With a filter system, you save money in the long term as there is no need to repeatedly buy bottled water. It is also a more sustainable option as there is less waste.

The EVOfilter therefore offers you a simple, environmentally friendly and economical way to treat your drinking water conveniently at home.

Importance of minerals in water

Minerals are important - but it depends on the form in which they are ingested. In drinking water, it is important to distinguish which minerals can be used by the body and which could be a burden. With the Evofilter, only those minerals that are potentially usable remain in the water.

Minerals from water and food

Drinking water and mineral water contain different amounts of minerals such as calcium and magnesium. A study conducted by Paderborn University on behalf of Forum Trinkwasser e.V. examined the importance of water for mineral supply. The result: water low in minerals is particularly suitable for hydration, while minerals are mainly supplied by solid food. So-called organically bound, biologically available minerals are important.

Exposure to inorganic minerals

Inorganic mineral salts in water are often difficult for the body to utilize and could even be a burden. For example, they can accumulate on crystals, promote the formation of deposits or contribute to the formation of stones. Just as water pipes become calcified with a high limescale content, residues could also build up in the body.

Difference between organic and inorganic minerals

As with all nutrients, minerals are generally more readily available in an organically bound form, for example through plants. Plants also contain secondary substances that can support absorption - similar to how vitamin D3 works better together with K2. Vitamin C is also comparable: as isolated ascorbic acid it is less well absorbed, but in apples it is much better. The same applies to minerals: minerals that are not organically bound in water are less easily absorbed and have to be excreted via the kidneys. Excess minerals could be deposited in the body and possibly contribute to the formation of stones.

Example: Osmotic pressure

The example of the cucumber in distilled water illustrates osmotic pressure: cells constantly regulate their salt content in exchange with their environment. However, it would not be correct to conclude from this that distilled water is fundamentally harmful to humans. Salt reserves in the body generally prevent an imbalance. Millions of people drink distilled water without any noticeable problems - some even report positive experiences. Hydrologist Prof. Vincent also pointed out that cleansing processes in the body could be particularly effective with pure water. In addition, nanofiltered water is not distilled, as it still contains trace elements.

Voices of doctors and researchers

Many doctors and researchers believe that soft, mineral-poor water could penetrate deeper into tissue and prevent deposits. Dr. Charles Mayo from the Mayo Clinic wrote that hard water could form insoluble compounds with fats, which could burden the metabolism and organs and promote the formation of stones. The Austrian magazine "Gesundheit" and Dr. Barbara Hendel also point out the possible benefits of low-mineral water.

WHO assessment

The WHO emphasizes that there is no reliable evidence for the health benefits of mineral-rich water. There are no known negative effects of water low in minerals. Minerals are mainly absorbed through food. A balanced diet provides sufficient vitamins and minerals - and pure water can fulfill its most important task: to cleanse and hydrate the body.

The renowned NIH, National Library of Medicine, has asked itself this question. Doctors and scientists trust this institution.

In addition, on behalf of Forum Trinkwasser e.V. (one of the largest drinking water associations in Germany), scientists from Paderborn University, led by Professor Helmut Heseker, investigated the importance of water in meeting mineral requirements. The long version of the study can be found in the appendix. The scientists came to the conclusion that water low in minerals is ideal for meeting fluid requirements. The German population's need for the most important minerals is primarily covered by solid food. So-called "organic" biologically available minerals.

To summarize:

Minerals in drinking water correspond to a maximum of 10% for calcium and 7% for magnesium of the recommended daily intake of 2 liters per day. Most trace elements are not even detectable and it has been scientifically proven that they cannot be easily absorbed by humans through drinking water.

1. Nerbrand et al. (2003): The influence of calcium and magnesium in drinking water on cardiovascular risk factors
   Summary: This study investigated the relationship between increased levels of calcium and magnesium in drinking water and cardiovascular risk factors in people living in areas with soft and hard water. The results show that there is a significant association between elevated calcium concentration in water and major cardiovascular risk factors, whereas magnesium in water or minerals in the diet did not show a comparable influence. This suggests that high calcium in drinking water could be a complex risk factor for cardiovascular disease.
2. Morr et al. (2006): Calcium content in bottled and tap water
   Summary: This study looks at calcium concentrations in bottled and tap water and their relevance for medical treatments. The results show that calcium levels vary widely and are typically as low as 8-20 mg/L in "longevity zones" in Russia. This suggests that low calcium concentrations in drinking water may correlate with longer life expectancy.
3. Druzhyak (2005): Water for health and longevity
   Summary: Druzhyak emphasizes that the calcium concentrations in the drinking water resources of regions with high life expectancy in Russia are extremely low (8-20 mg/L). This supports the hypothesis that low mineral content in drinking water may contribute to health and longevity.
4. Siener et al. (2004): Mineral water and the risk of calcium oxalate crystallization
   Summary: This study investigated how mineral-rich water (with high concentrations of magnesium, calcium and bicarbonate) influences urine composition. It was found that consumption of such water can increase the risk of calcium oxalate crystal formation. This suggests that a high mineral content in the water could play a role in the formation of urinary stones.
5. Bellizzi et al. (1998): Influence of water hardness on kidney stone risk
   Summary: This study analyzed the effects of hard and soft water on urinary composition in patients with idiopathic nephrolithiasis. The results show that hard water significantly increases urinary calcium concentration, which increases the risk of calcium stone formation. Soft water (e.g. Fiuggi water) is considered more beneficial due to its lower risk profile.

These studies suggest that low levels of minerals in drinking water could potentially be beneficial, particularly in relation to cardiovascular disease and kidney stones.

Water in the human body

In middle age, our organism consists of around 70% water. In infants, the proportion is around 80 % and in old age around 60 %. These figures illustrate the central importance of water.

The picture on our planet is similar: around three quarters of the Earth's surface is covered by water, with only a quarter consisting of land. Depending on the species, plants contain between 20 % and almost 100 % water. Even stones and metals are not completely free of water.

Tasks of water

Water fulfills numerous functions in the body:

• Heat conduction and temperature equalization
• Transport and solvents
• Buffer and protection system
• Upholstery and filler
• Cleaning vehicle

The cleansing function is particularly important. Around 180 liters of fluid are filtered in the kidneys every day, of which around 178 liters are reabsorbed. This means that important substances remain in the body, while urinary substances such as salts, uric acid, heavy metals and degradation products are excreted.

Stress on the kidneys

If the kidneys can no longer cope with this work, there is a risk of gradual poisoning of the body. Tiredness, lack of concentration or high blood pressure can be the first signs. Additional salts or heavy metals from food and drink have a particularly harmful effect, as they can overload the fine renal tubules.

Inorganic and organic minerals

A central problem lies in the distinction between organically bound and inorganic minerals. The latter are difficult for the organism to utilize and can be deposited in the body - similar to lime in pipes. Organically bound minerals, such as those found in plants, are more readily available. The pharmaceutical industry therefore also binds minerals to organic substances such as citrate or gluconate in order to increase bioavailability.

Overuse and its consequences

An excess of inorganic minerals can change the blood environment: The pH value increases and the electrical resistance (rho value) decreases. Such conditions favor vascular diseases and aging processes. The growing consumption of mineral-rich water is associated with an increase in cardiovascular diseases. Too much matter - whether in the form of minerals or in traffic - leads to "congestion", which impedes the flow of life. 

Drinking water quality

Clean drinking water should be free from heavy metals, pesticides, bacteria and other pollutants - and at the same time contain as few inorganic minerals as possible. The mineral requirement is covered by plant and animal foods. Water, on the other hand, is primarily used as a solvent and cleaning agent.

Research results

Prof. L.C. Vincent from the Institute of Anthropology at the University of Paris showed in decades of research that laboratory animals remained healthier and lived longer if they were given water that was low in minerals. In contrast, disorders occurred more frequently with mineral-rich water.

Conclusion

Low-mineral water can be considered a valuable cleansing aid for body and mind. Among the available methods, reverse osmosis is considered the most effective way to obtain such water. Perhaps truly clean water leads not only to physical clarity, but also to mental clarity.

Ionizers are often used to change the pH value of water and make it alkaline. There are a few points that should be taken into account:

1. pH changes in the water: Ionizers change the natural pH value of the water, which could have long-term effects on the body. It should be borne in mind that the body has natural mechanisms for regulating the acid-base balance.
2. Filtration of pollutants: Ionizers usually use activated carbon filters, which in certain cases can only remove larger particles or contaminants up to a certain size. This means that potential pollutants such as heavy metals, chemicals or microplastics may not be completely removed.
3. Scientific basis: There is currently no unanimous scientific opinion on the health benefits of ionized water. When choosing a water treatment system, it makes sense to focus on technologies that have been independently tested and can effectively remove certain contaminants.
4. Safety of use: It is important to ensure that water treatment systems are tested for their filtration performance and potential impact on water quality. Systems that filter additional contaminants may be more useful for reliable water treatment.

In summary, it is advisable to inform yourself well before buying an ionizer and to check possible alternatives that remove pollutants more efficiently or are more sustainable.

Advertising often claims that reverse osmosis membranes have a pore size of 0.0001 micrometers, which corresponds to 0.1 nanometers. However, this statement does not correspond to physical reality and is not scientifically tenable. It is often used purely for marketing purposes and leads many consumers to a false understanding of how reverse osmosis actually works.

Reverse osmosis membranes consist of several layers, with the separating layer consisting of a dense polyamide. This layer is produced using a special process in which two chemical components combine at an interface to form a dense polymer film. Underneath this is a mechanically stable carrier layer made of polysulfone or polyethersulfone, which supports the membrane but does not perform a separating function itself.

There are no open pores in the active polyamide layer, such as those found in a sieve or filter. Instead, the structure is amorphous and dense, comparable to a close-meshed network on a molecular level. Water is not transported through pores, but via a so-called solution diffusion mechanism. Due to their small size and polarity, water molecules dissolve in the polymer matrix of the membrane, diffuse through the material and emerge on the other side. This process is only possible for certain molecules, especially water. Dissolved salts, heavy metals, drug residues or other pollutants are retained in the polymer either because of their size or because they are not chemically soluble.

A single water molecule has an effective diameter of around 0.275 nanometers. A membrane with real pores of only 0.1 nanometers would completely retain even water, which would make the function of reverse osmosis impossible. The often quoted pore size of 0.1 nanometers is therefore not a real physical value, but a mathematically derived approximation based on the retention rate of certain molecules. This figure has become commonplace in marketing over the years, but does not correspond to the actual structure and function of the membrane.

Evodrop deliberately relies on scientifically substantiated values when specifying the effective separation characteristics. Our membranes have an effective molecular separation efficiency of around 0.5 nanometers. This value is based on the actual physical properties of the materials used, on measurements and on the analysis of the actual molecule sizes that are retained or allowed to pass through. In this way, we guarantee not only transparency but also technical accuracy, which is essential for applications in the field of water treatment.

For the best possible filtration performance, we recommend a 30-second pre-rinse time.

If the water has stagnated for more than a week, it is advisable to let it run for a minute. The membranes relax when not in use. In technical jargon, this phenomenon is known as a "TDS gap". The membranes relax after a certain time due to the standstill of water pressure and pump pressure.

As a result, we recommend allowing the membranes to pre-run for approx. 30 seconds.

The pre-rinse water can be used without hesitation for watering house plants.

The filter must be serviced after 10,000 liters or at the latest after 5 years with a water hardness of up to 40°fH. The cost of the replacement kit is 499CHF. For 699CHF the maintenance is carried out by our service technician and for 990CHF the guarantee can be extended for a further five years if desired.

The EVOfilter comes with a five-year warranty. The warranty can be extended. Please note, unlike competitors such as Truu Water, we do not only cover the housing, but the entire system.

The EVOfilter emits an acoustic signal after 10,000 liters when the filter is used. The pre-filter and the two membranes should then be replaced within the next 2000 liters.

Filter maintenance is child's play in two minutes thanks to a bayonet catch.

The EVOfilter is installed at any water connection in your home. This can be the kitchen, the cellar or the bathroom. The EVOfilter is not installed directly on the main inlet water pipe in the house!

You need a cold water connection, a power socket, enough space for the filter and a waste water siphon.

Of course, we leave the choice of installation to you and you can install the EVOfilter yourself. However, we recommend professional installation by a plumbing specialist, who can also guarantee the installation.

We offer a five-year guarantee on the entire filter, provided that the filter has been installed correctly and is used as intended. Optionally, the warranty can be extended by a further five years for an additional charge.

The system is automatically flushed every four hours to prevent bacteria from building up and multiplying - the Swiss standard is once a day. This means we are well above the SVGW values. In addition, our membrane is smaller than the bacteria and no more bacteria can form. Finally, the structure of the Evodrop membrane guarantees a constant filter performance because it does not become dirty and clogged due to the larger contact surface, as can happen with conventional reverse osmosis systems, for example. Finally, the Evodrop system has a small germ filter to ensure germ-free water. In contrast, the competition either offers no solution or, paradoxically, irradiates the water with UV. Last but not least, all hoses in the EVOfilter are treated with a natural antimicrobial coating so that no bacteria can settle in the entire system. The EVOfilter has a total of four patented technologies that make it the best and safest filter on the market.

You can also use this for a rented apartment without any problems. Everything is included in the price, from the installation kit to a new tap. However, we recommend buying a 3-in-1 tap for a rented apartment (through us or Sanitary) so that you don't have to drill a separate hole. You can find our range of different taps in the online store. Alternatively, you can easily install a small separate tap next to the stopper or soap dispenser without having to drill a hole. The system can be easily dismantled and taken away.

You are welcome to contact us by telephone, send us an e-mail or order a filter directly via our webshop.

The pH value describes whether a liquid is acidic, neutral, or alkaline. Drinking water naturally ranges from slightly acidic to neutral. This range is technically normal and poses no sensory problems.

Water filtered by Evodrop typically has a pH value of around 6.5 to 7.0. This value is within the natural range of many beverages and foods.

It is important to take an objective view:
The measured pH value of a beverage does not allow any conclusions to be drawn about how it is processed in the human body. The body's acid-base balance is regulated by complex physiological mechanisms and is not directly influenced by the pH value of individual beverages.

A well-known example from nutrition science illustrates this point: Lemon juice has a low pH value, but is processed differently in the metabolism than the measured value would suggest. This example shows that the pH value of a food is not a reliable indicator of its physiological classification.

Many fruits and vegetables also have a pH range between approximately 5.5 and 7.5, without this affecting their quality or tolerability.

Devices for producing so-called alkaline water increase the pH value by adding additional, mostly inorganic minerals to the water. This increases the mineral concentration and, as a result, the pH value. This technical modification of water is often advertised as having health benefits, but is scientifically controversial.

A key point is the physiological role of the stomach. The human stomach works under highly acidic conditions with a pH value of around 1.5 to 2. This acidity is essential for protein digestion, killing germs, and mineral absorption. If highly alkaline water is consumed regularly, the stomach must neutralize these bases. This does not lead to relief, but on the contrary to increased acid production as a compensatory reaction.

It is important to make a clear conceptual distinction here:

Alkaline water with pH values above 8 and added inorganic minerals is not equivalent to fresh fruit and vegetables. Plant-based foods contain organically bound minerals and typically have a pH range of around 5.5 to a maximum of 7. Their effect on metabolism is fundamentally different and cannot be transferred to technical, alkalized water.

Scientific background and classification

The health benefits of alkaline water are not universally accepted among experts. To date, there are no reliable long-term studies that prove a lasting health benefit from permanently increased drinking water pH. However, it is known that water with a high calcium or magnesium content reacts with oxygen under certain conditions, causing the pH value to rise. Whether this change is beneficial does not depend on marketing promises, but on physiological needs, and these do not usually exist in healthy people.

The electrolytic separation of water into acidic and alkaline components is also viewed critically. Several experts point out that this artificial polarization of water does not correspond to natural drinking water or human physiology.

Classification of filter technology

The benefits of high-quality water filters for reducing pollutants and unwanted residues are undisputed. However, optimizing water quality should focus on purity, sensory quality, and pollutant reduction, not on forced pH manipulation. A filter is useful. Electrolysis with separation into acidic and alkaline water, on the other hand, is not scientifically justifiable.

Expert voice from the scientific community

In this context, it is worth taking a look at critical specialist articles, such as those by Jordan Petrow. He combines medical and engineering perspectives and has been dealing with systemic relationships in physiology for decades. His explanations question simplified concepts such as the blanket alkalization of the body and place them in a broader physiological context.

Risks and counterarguments

There is no reliable evidence that alkaline water permanently "deacidifies" the body. The body regulates its acid-base balance with high precision via the lungs, kidneys, and buffer systems. External manipulation via drinking water is neither necessary nor particularly effective in everyday life and can be counterproductive in extreme cases.

Specific recommendation

From a technical and legal perspective, it is advisable to exercise caution when making statements about alkaline water. It makes sense to focus on clean, pollutant-free drinking water without unnecessary chemical or electrolytic changes. Anyone wishing to obtain more detailed information should refer to independent specialist sources and scientific discussions and critically question marketing promises.

Scientific research has clearly demonstrated that water molecules interact with each other via hydrogen bonds. These interactions cause water molecules to temporarily organize themselves into preferred arrangements. In this context, the technical literature often refers to molecular networks or clusters.

These arrangements are not rigid, but dynamic. They arise, change, and continuously dissolve again. It is precisely this mobility that characterizes many of the well-known physical properties of water.

Scientific background

Investigations using spectroscopic methods such as infrared and Raman spectroscopy, as well as molecular dynamics simulations, show that water is not a random collection of individual molecules. Rather, it is a finely tuned system of constantly changing interactions.

These findings help to better understand the special behavior of water, such as its solubility, surface tension, and reaction dynamics. The clusters described are not isolated units, but snapshots within a continuous process.

Objective demarcation

The current state of science deliberately describes these molecular arrangements as temporary and situation-dependent. No conclusions can be drawn from this about permanently stable structures or specific health effects. Accordingly, no medical or therapeutic promises are derived from the term water clustering.

This restraint does not constitute a restriction, but rather corresponds to sound scientific methodology and a realistic assessment of the research results.

Classification at Evodrop

Evodrop refers to these scientific principles without simplifying or overstretching them. The focus is on comprehensible physical processes such as movement, flow, and dynamics of water. Statements about biological or health effects are deliberately not made.

Hydrogen bonds are considered a key structural feature of water and explain many of its well-known properties. However, they are not an isolated mechanism, but interact with other physical forces that influence the behavior of water at the molecular level.

Additional interactions discussed in research include:

Van der Waals interactions

These weak intermolecular forces contribute to the short-term stabilization of molecular arrangements and influence the spatial orientation of water molecules. They are routinely used in physical chemistry to describe collective effects.

Quantum physics models

Some theoretical works, including those by Del Giudice and colleagues, examine quantum physical approaches to describing the dynamics of water. These models are discussed as theoretical extensions of classical concepts and serve to improve our understanding of complex interactions, without being considered a generally accepted standard.

Electromagnetic influences

Individual studies address the question of how electromagnetic fields can influence molecular arrangements in water. Such work broadens our view of water as a physical system, but continues to be critically examined and scientifically classified.

surface interactions

It is well established that hydrophilic and hydrophobic surfaces can locally alter the behavior of water. Ordered molecular layers form in interface areas, which differ measurably from freely moving bulk water.

Scientific classification

The research projects mentioned above use established experimental and theoretical methods such as spectroscopy, model calculations, and surface analyses. They contribute to understanding water not as a simple liquid, but as a dynamic, reactive system.

This is an active field of research with different models and interpretations. The effects described are considered context-dependent and are not understood as universally stable states.

The term "structured water" and designations such as H3O2 or "hexagonal water" are used in various publications and marketing presentations to describe a supposedly special form of water.

The starting point for these descriptions is often the observation that the human body consists largely of water and that water occurs in highly organized environments within biological systems, such as cells.

This fact has led to the assumption that drinking water must also have a special, permanently ordered structure in order to be particularly beneficial to the body. This suggests that water molecules are organized in stable clusters and are therefore fundamentally different from ordinary H₂O.

Classification of the claimed advantages

Proponents of so-called structured water sometimes attribute improved hydration properties or easier absorption by cells to it. In addition, isolated effects such as increased energy levels, support for cellular processes, or easier excretion of metabolic waste products are claimed. However, there is no generally accepted scientific evidence to support these claims.

It is scientifically undisputed that water plays a central role in biological systems. However, this does not mean that drinking water must or can have a specific, permanently stable structure in order to fulfill these functions.

Reference to spring water

Structured water is often compared to natural spring water. It is argued that water acquires special physical properties as it flows over rocks, through pressure, movement, and mineral environments.

Such comparisons serve primarily to illustrate natural processes. However, they do not constitute proof that spring water or so-called H3O2 water has a clearly defined, stable special molecular structure.

From a scientific point of view, water changes continuously depending on temperature, pressure, movement, and environment. This dynamic is a fundamental characteristic of water and does not indicate a permanently "structured" state in the sense of specific cluster forms.

Role of alternative concepts

The popularity of the term "structured water" can also be attributed to trends in alternative medicine and related fields. In these fields, water is sometimes associated with concepts such as detoxification, reduction of oxidative stress, or harmonization of biological processes. Such concepts are often based on simplified or scientifically unproven explanatory models.

Link to anti-aging and performance enhancement
Another aspect of the hype is the assumption that structured water can slow down the aging process or increase physical performance. These ideas are usually based on effects on free radicals or cell metabolism. Again, there is no reliable scientific evidence to support this.

Classification from Evodrop's perspective

Evodrop clearly distances itself from such claims. Statements about structured water, H3O2, or hexagonal water are not understood as medical or health properties. Evodrop is based on verifiable physical principles of water treatment and deliberately avoids unsubstantiated or speculative claims.

Flowing water energizes minerals (Max Planck Institute) (PDF)

From a scientific perspective, there is well-researched evidence that water in biological systems, especially within cells, is not completely disordered. Rather, research shows that water molecules in close proximity to biomolecules can adopt certain ordered arrangements. This organization is context-dependent, dynamic, and part of normal cellular processes.

Ordered water layers on biomolecules

In human cells, water forms so-called hydration layers around proteins, nucleic acids, and other macromolecules. These water molecules are organized spatially and energetically differently than freely moving bulk water. Such hydration layers are an established component of biochemistry and contribute to the stability, folding, and function of biomolecules, for example in enzymatic reactions or the structural integrity of cell components.

Classification of the EZ water hypothesis

Biophysicist Gerald Pollack has described the concept of so-called exclusion zone water, in which water near certain surfaces forms an ordered zone that is partially excluded from dissolved substances. This hypothesis is being discussed and further investigated in the scientific community. It represents a theoretical approach that attempts to explain observations at interfaces, but is not generally accepted as proof of an independent, permanently stable state of water in the body.

The significance of orderly water arrangements

The fact that water is temporarily ordered in the vicinity of cell membranes, proteins, or other structures is considered to be part of normal physical-chemical interactions. Such arrangements enable efficient biochemical processes and support the functionality of cellular systems. However, no direct conclusions about specific health effects or therapeutic effects can be drawn from this.

Dynamism instead of stability

A key feature of these water arrangements is their dynamism. The structures are not permanently stable, but change continuously depending on temperature, charge conditions, molecular interactions, and cellular requirements. This flexibility is a fundamental component of biological systems and does not indicate a permanently "structured" state of water.

Classification from Evodrop's perspective

Evodrop makes a clear distinction between scientifically described water organizations in biological systems and speculative statements about structured drinking water. References to ordered water arrangements in cells are not understood as evidence of health benefits. Evodrop is based on verifiable physical principles and deliberately refrains from making medical or therapeutic claims.

Summary

Research shows that water in biological systems can be locally and temporarily organized, especially in the vicinity of biomolecules. This organization is part of normal physicochemical processes and is highly dynamic. No conclusions can be drawn from this about permanently structured water or specific health effects.

UV light is often used in water treatment to inactivate microorganisms. Short-wave UV radiation damages the nucleic acids of bacteria and viruses, preventing them from multiplying. This process is technically established and is used in particular in drinking water hygiene.

At the same time, it should be noted that UV treatment is exclusively a disinfecting measure. It does not alter chemical contaminants, remove pollutants, or affect the mineral composition of the water. Furthermore, UV light does not act selectively on microorganisms alone, but is generally a high-energy radiation that can influence the physical properties of water. Experts differ in their assessment of how relevant these changes are for the practical use of drinking water.

Evodrop therefore takes a different approach. Instead of treating water with high-energy radiation, EVOCharge relies on purely physical refinement through controlled flow and rotation. This sets the water in motion without chemically altering it or exposing it to ionizing radiation. This approach is based on natural flow processes and aims to optimize the physical dynamics of the water, not its biological or medical effects.

Evodrop expressly makes no statements about effects on cells, DNA, the immune system, or disease processes. Statements about water as a biological or therapeutic agent are avoided. EVOCharge is not a medical procedure and does not replace hygienic disinfection where this is required by law or for technical reasons.

Clarification of frequently cited concepts

In public debate, UV treatment and water refinement are sometimes linked to terms such as "information loss," "biophotons," or "cell water structure." These concepts originate from various scientific or theoretical approaches, but are not part of generally accepted drinking water standards and do not allow for reliable statements about the health effects of UV-treated water.

Evodrop expressly distances itself from such interpretations and limits itself to comprehensible, physically describable processes within the scope of water treatment.

If you have installed the EVOcharge compliant to the cold water system and after an efficient filter system (our recommendation: EVOfilter/EVOdrink), the EVOcharge is completely service and maintenance-free.

The EVOcharge is simply connected to our EVOfilter/EVOdrink or a similar filter system. Thanks to simple push-in connections, one hose is plugged into the inlet and one hose into the outlet of the EVOcharge.

The EVOcharge is easy to install. With the right hose connections, the EVOcharge can be installed very simply and without any manual skills.

As it flows through the EVOcharge, the water is subjected to an intense, controlled rotational movement. This movement increases the contact surface between the water and the ambient air, particularly in the area of the tap and immediately after the water emerges.

Under certain conditions, this can lead to more dissolved oxygen in the water. Measurements show that the dissolved oxygen content can vary depending on factors such as water temperature, source water, and flow rate.

The EVOcharge itself does not add oxygen to the water and does not change the chemical composition of the water. Observed changes relate exclusively to physical parameters, in particular mixing and contact with the ambient air.

The physical refinement of water produced by EVOcharge is based on controlled flow and rotation. This gives the water a changed movement and flow dynamic. These physical properties do not remain unlimited, but are dependent on external influences such as storage, movement, temperature, and contact with air or surfaces.

Observations on temporal stability

Under calm conditions, for example when stored in a closed container without renewed strong turbulence, certain physical properties of the water can be preserved for a limited period of time. The duration can vary and depends on the source water and the environmental conditions.

Comparison with other methods

Compared to purely passive methods such as static swirlers, stones, or carafes, where effects are often only observed directly in the vessel itself, the EVOcharge generates active flow dynamics. This allows the perceptible physical properties of the water to remain evident for a certain period of time after bottling, as long as there is no renewed strong mechanical influence.

Classification of external studies

Studies conducted by various institutes focus on describing the physical properties of water under different conditions. Such analyses provide evidence of differences between water samples, but do not constitute generally accepted proof of permanently stable water structures. Accordingly, these results are interpreted as observations and not as absolute or universal statements.

Clear demarcation

Evodrop makes no claims about permanently stable water structures over weeks or months, nor does it make any superlative claims in comparison to other water sources. Terms such as structure or refinement refer exclusively to the physical properties of the movement and dynamics of water, not to chemical, biological, or health effects.

Summary

The physical water refinement produced by EVOcharge is temporary and depends on the respective storage and usage conditions. It differs from static methods in that it actively generates flow without claiming to be a permanently fixed structure.

Due to its molecular properties, water exhibits exceptionally complex behavior. Water molecules are polar and constantly interact with each other via hydrogen bonds. In addition, other physical forces such as van der Waals and dipole-dipole interactions come into play. This combination means that water is described not as a static medium, but as a dynamic system.

For decades, physical chemistry and molecular research have been investigating how water molecules temporarily combine to form larger structures. These short-lived structures are often referred to as clusters. They form and change continuously depending on environmental influences such as temperature, pressure, movement, surface contact, or dissolved ions.

Experimental and theoretical investigations

Established methods such as nuclear magnetic resonance (NMR), infrared spectroscopy (FTIR), molecular dynamics simulations, and quantum chemical models are used to investigate these molecular arrangements. These methods show that water forms preferred arrangements of two, several, or even larger groups of water molecules in certain environments. Configurations involving several molecules are particularly frequently described, although these are not permanently stable states.

Influence of environment and dissolved substances

Research also shows that dissolved ions such as calcium, magnesium, or other minerals can influence the local organization of water molecules. So-called hydrate shells form around such ions, in which water molecules are arranged differently than in free bulk water. These effects are well described and form part of classical water chemistry.

Dynamism instead of fixation

A key feature of all the water clusters described is their dynamic nature. They are not permanently stable, but part of a constantly readjusting equilibrium. Changes in the physical or chemical conditions cause these arrangements to reform or dissolve again. Water thus continuously adapts to its environment.

classification

Scientific research confirms that water is highly dynamically organized at the molecular level and has short-term arrangements. However, statements about permanently "structured" water or specific health effects cannot be derived from this. The term structured water is therefore mainly used as a simplified description of complex physical processes.

Summary

Water is a dynamic system with temporary molecular arrangements that are investigated using modern measurement and modeling techniques. These findings deepen our physical understanding of water and are relevant to chemistry, materials science, and technical applications—without implying any medical or therapeutic claims.

Patented rotary nozzle technology

Unlike many swirl generators or magnetizers available on the market, which usually work with static elements or simple deflections, the EVOtransform uses patented rotary nozzle technology. This actively sets the water in motion with an intense flow and circulation. This controlled rotation is based on fluid dynamics principles and serves to specifically influence the physical properties of the water. The process is reproducible, technically defined, and fundamentally different from passive systems.

Active rather than short-term effects

Many simple vortex generators merely create a short-term movement of the water directly in the device. The EVOtransform, on the other hand, relies on active flow dynamics that not only have a selective effect, but also set the water as a whole in motion. Statements regarding duration or stability refer exclusively to the physical properties of the water movement and not to chemical, biological, or health effects.

Independently tested

The EVOtransform has been technically tested by independent institutes. These tests relate to the functionality, flow characteristics, and physical parameters of the water. Evodrop does not derive any medical or health claims from this. In the market environment, such technical testing is not a matter of course for simple vortex generators or magnetizers.

Purely physical approach

While other systems work with magnetic fields, coatings, or additional components, the EVOtransform is based exclusively on physical flow and movement. No substances are added, no minerals are altered, and no chemical processes are triggered. The focus is on nature-inspired, mechanical-physical water treatment.

Quality, origin, and durability

The EVOtransform is manufactured entirely in Switzerland. SwissMade production ensures high precision in the manufacture of all components. High-quality V4A stainless steel is used. The device is designed to be maintenance-free and built to last. Evodrop offers a 20-year warranty.

Summary

The EVOtransform differs from conventional swirl generators and magnetizers in its active, patented flow approach, its purely physical mode of operation, its high-quality Swiss-made design, and its technical verifiability. It deliberately avoids making unsubstantiated claims and focuses on comprehensible engineering technology.

The EVOtransform works entirely without chemicals or additives. It is therefore an environmentally friendly addition to traditional water softening systems, which often use salt or sodium. The device is designed to be maintenance-free and incurs no running costs.

Patented rotating nozzles set the water in active physical motion. This motion is based on natural flow processes and is often compared to a stream flowing over a distance of around 20 to 30 kilometers. The comparison serves to describe the intensity of the water motion and does not represent a scientific equivalence.

Physical agitation affects the solubility and wetting behavior of water. In practice, this can contribute to more efficient use of care, washing, and cleaning products. Many users report that smaller amounts of detergent, cleaning agent, or dishwashing liquid are sufficient, which reduces consumption and can decrease direct contact with cleaning agents in everyday life.

Even in everyday use, the water is often perceived as soft and pleasant. This sensory perception is subjective and can vary from person to person.

Important distinction

The EVOtransform is not a water softening system and does not change the water hardness or mineral content of the water. It is used exclusively for physical water treatment and to optimize the user experience. If you have your own natural water source, it is not usually necessary to use an EVOtransform.

Summary

The EVOtransform offers a maintenance-free, chemical-free, and purely physical addition to water treatment. It is aimed at consumers who value environmental friendliness, high-quality technology, and a pleasant everyday water experience without interfering with the chemical composition of the water.

Hydrogen bonds are a key structural feature of water and explain many of its well-known physical properties. However, modern research shows that they interact with other physical interactions and are not sufficient on their own to describe the full complexity of the molecular organization of water.

In addition to hydrogen bonds, the following influences, among others, are discussed in scientific literature:

1. Van der Waals interactions:
   These comparatively weak intermolecular forces contribute to the short-term stabilization of molecular arrangements and influence the spatial geometry of water molecules. They are an established component of physicochemical models used to describe collective effects in liquids.
2. Quantum physics models:
   Several theoretical studies, including those by Emilio Del Giudice and colleagues, examine quantum physics approaches to describing water dynamics. These models expand on classical concepts and are considered part of a scientific discourse that addresses complex interactions at the molecular level.
3. Electromagnetic influences:
   Studies such as those conducted by Luc Montagnier and his colleagues examine whether and how electromagnetic fields can influence the organization of water molecules under experimental conditions. Such work is critically discussed among experts and classified as exploratory contributions to the physical description of water.
4. Surface interactions:
   The influence of hydrophilic and hydrophobic surfaces on the arrangement of water molecules is well documented. Studies, including those by Tarov et al., show that ordered water layers form at interfaces, which differ in their properties from freely moving bulk water.

Classification of scientific evidence

The aforementioned work is based on recognized experimental and theoretical methods such as spectroscopy, model calculations, and surface analyses. They consistently demonstrate that water is a highly dynamic system whose molecular organization arises from the interaction of several physical forces.

This multidimensional view broadens our physical and chemical understanding of water and explains why it plays such a special role in biological, chemical, and technological contexts. Evodrop does not derive any medical or therapeutic claims from this, but rather understands these findings as an expression of the extraordinary adaptability and complexity of water as a physical medium.

No. The EVOtransform does not remove lime from the water and does not replace a water softener. Calcium and magnesium ions remain completely in the water, as does the measurable water hardness.

The EVOtransform acts exclusively on the flow and movement behavior of the water. Intensive circulation and controlled flow change the conditions under which calcareous deposits can form. In practice, this can help reduce the amount of calcium carbonate that accumulates on pipes, fittings, and surfaces.

The formation of limescale in water is a chemical equilibrium between dissolved calcium, hydrogen carbonate, and carbon dioxide. EVOtransform does not chemically attack this equilibrium, nor does it specifically alter the pH value or actively remove CO₂ from the water. Magnetic fields, electric currents, or other magnetohydrodynamic effects are also not used.

Instead, the effect is based on known physical relationships between flow dynamics and crystallization conditions. The difference lies not in the removal of limescale, but in the altered deposition behavior.

Summary

The EVOtransform does not decalcify the water. However, it can help to reduce limescale deposits in the pipe system and on surfaces without changing the water hardness or mineral content.

Physical water treatment with the EVOtransform changes the conditions under which limescale deposits form on surfaces in the home. In practice, this can help to reduce the amount of limescale that builds up on pipes, fittings, and water-carrying systems. This reduces deposits that can lead to increased cleaning requirements or functional impairments in the long term.

Household appliances such as washing machines, dishwashers, boilers, and coffee machines also benefit from reduced limescale buildup. Less limescale can help appliances function better and reduce the amount of maintenance they require on a daily basis. Statements regarding service life are based on typical usage experiences and do not constitute a guarantee.

In daily use, many users report that textiles feel softer after washing and that detergents and cleaning agents can be dosed more efficiently. In dishwashers, too, the need for regeneration salt and detergents can be reduced, while limescale marks on glasses and dishes are less noticeable. These effects depend on water quality, usage, and individual settings.

The physical circulation in the EVOtransform causes the water to move intensively. This movement can promote the mixing of the water and encourage contact with the ambient air, especially when it comes out of the tap.

Under certain conditions, this can lead to an increase in the dissolved oxygen content in the water. Oxygen content measurements can vary depending on the source water, water temperature, flow rate, and measurement method.

The EVOtransform does not add oxygen to the water and does not alter its chemical composition. Any differences observed relate exclusively to the physical effects of the movement and mixing of the water.

Important classification

Information on dissolved oxygen is purely physical measurements and does not represent any statement about health, biological, or performance-related effects.

Summary

Under certain conditions, EVOtransform can contribute to a change in the oxygen mixing of the water. No statements are made regarding fixed percentages or health effects.

No. The EVOtransform is based on a purely physical process without the use of chemicals and is installed with corrosion- and erosion-free material. This makes the system maintenance-free. You also receive a 20-year guarantee on the system, provided it is not dismantled or used improperly.

The EVOtransform is installed on your main water pipe directly after the water meter and sediment filter. We recommend having the installation carried out by a certified plumber.

No. As the EVOtransform must be connected to the main water pipe and installation is somewhat more complex, we recommend having the installation carried out by a certified plumber. The installation requires special tools and a certain amount of expertise in building services. If you do not have a plumber you trust, we will be happy to organize installation by one of our specialist partners in your area.

We offer a 20-year guarantee on the EVOtransform.

In the EVOdescale system, calcium and magnesium ions in the water bind to malic acid. This creates stable organic complexes, in particular calcium malate.
This complexation fundamentally changes the chemical state of the minerals.

By binding to malic acid, the minerals are no longer present as freely available calcium carbonate. This prevents them from crystallizing into traditional lime (CaCO₃) and accumulating on pipes, fittings, or surfaces.
The minerals remain in the water but are chemically bound.

These organically bound minerals do not dissolve from the bond under normal operating and household conditions, so that no new limescale is formed.

This also applies when the water is heated, as the calcium ions are no longer present in the free form required for limescale formation.

The key difference to physical conversion systems is that the lime is not merely changed in its crystal form, but is chemically bound.

EVOdescale does not work with seed crystals, magnetization, or turbulence, but rather through targeted organic complexation of the lime-forming ions.

Important:

The minerals are not removed, but permanently bound. The water composition remains unchanged, while limescale deposits are reliably prevented.

Conventional salt-based water softeners, on the other hand, work by means of ion exchange. This process completely removes calcium and magnesium ions from the water, regardless of their function, and replaces them with sodium ions. It is not technically possible to selectively distinguish between lime-forming ions and mineral components.

Yes. The malic acid used in EVOdescale is a natural, well-researched substance whose properties and safety have been comprehensively evaluated. Malic acid (E296) is approved as a food additive in the European Union and Switzerland.

Malic acid is approved for use in foodstuffs in accordance with EU Regulation No. 1333/2008 and the Swiss Foodstuffs Ordinance (LMV). This approval is based on extensive toxicological and safety assessments.

Assessment by European and international expert committees
The EFSA (European Food Safety Authority) has re-evaluated malic acid and its salts (EFSA Journal 2017;15(3):4727). The key findings are as follows:

• No safety concerns with the evaluated application quantities
• No need to set an ADI (Acceptable Daily Intake)
• No evidence of genotoxic effects
• Complete metabolism via established biochemical metabolic pathways

The JECFA (Joint FAO/WHO Expert Committee on Food Additives) also comes to similar conclusions in its toxicological assessment of malic acid. The WHO Food Additives Series 16 states:

• No toxicologically relevant effects
• No ADI restriction required
• Assessment for use in foodstuffs

These assessments relate to the safety of the substance itself and are used for regulatory classification purposes.

International classification

In the United States, malic acid has GRAS (Generally Recognized As Safe) status according to the FDA. It is approved there for numerous applications, including in beverages with significantly higher concentrations than in technical water treatment applications.

Chemical registration

Furthermore, malic acid is registered with the European Chemicals Agency (ECHA) in accordance with the REACH Regulation (EC) No. 1907/2006. This registration confirms the permissible use of malic acid in technical applications, including water treatment.

The ECHA assessment regulates chemical safety, registration, and use, but does not constitute a medical or health statement.

Classification in the context of Evodrop

Evodrop uses malic acid exclusively in the context of technical water treatment. The evaluations and studies cited confirm the regulatory admissibility and chemical safety of the substance, but not the medical or health effects of the treated water.

Unlike traditional salt-based water softeners, which replace calcium and magnesium ions with sodium ions, Evodrop works without ion exchange and without salt. The natural minerals remain completely in the water.

Instead, calcium and magnesium ions are chemically complexed by malic acid. This produces stable organic complexes, in particular calcium malate and magnesium malate. These organically bound minerals are up to 100 times more water-soluble than classic calcium carbonate (CaCO₃) and are therefore no longer available for the formation of limescale deposits.

This complexation process keeps the minerals dissolved in the water, but prevents them from settling as hard limescale on pipes, fittings, or appliances. The water behaves like soft water in everyday use, even though its mineral composition remains unchanged.

Even when heated, for example in hot water systems or during cooking, the minerals remain predominantly in their organically bound form. This effectively prevents the reaction with carbonate ions that is necessary for limescale formation.

Classification of measured values

Conventional test strips or simple hardness measurements continue to indicate the original water hardness, as they only measure the total amount of dissolved mineral ions. They do not distinguish between freely available hardness components and organically complexed minerals. Accordingly, the TDS value (Total Dissolved Solids) also remains unchanged.

The decisive factor is not the measurement value obtained using cheap test strips that are only designed to react to mineral ions, but rather the chemical behavior of the minerals in the water:

The minerals are bound, highly water-soluble, and lime-inactive—there are no lime deposits without removing minerals or adding sodium.

Both descaling systems achieve a descaling rate of at least 80 % in the test in the German accredited DVGW laboratory. Evodrop achieved 100 % with a score of 1.

Conventional water softeners remove the limescale content of the water by ion exchange. In this process, positively charged ions such as calcium (Ca²⁺) and magnesium (Mg²⁺), which are responsible for water hardness, are replaced by sodium ions (Na⁺). This reduces the limescale content in the water. However, such systems do not differentiate between desirable minerals and undesirable limescale, so both are removed.

Disadvantages of a descaling system or softening system with salt:

1. Increased sodium content in drinking water: During descaling by ion exchange, sodium ions get into the drinking water, which can pose health risks for people with high blood pressure or heart problems.
2. Environmental pollution from saline wastewater: The saline and chloride-containing wastewater produced during regeneration can damage bodies of water and ecosystems, as has been proven several times in various studies.
3. High water consumption during regeneration: Regeneration of the resin requires additional water, which leads to higher water consumption and an unnecessary strain on resources.
4. Regular maintenance and costs: Salt systems require constant maintenance and the purchase of additional salt, which involves additional costs and time. If you do not have an annual service carried out, the guarantee is void.
5. Removal of valuable minerals: Ion exchange not only removes limescale, but also important minerals that are essential for health, such as calcium and magnesium.
6. Risk of contamination and legionella: Harmful contamination can occur in salt tanks if the water is not flowing or the system is not properly maintained.
7. High water consumption during regeneration: Between 80 and 150 liters of water are used per regeneration, which is an unnecessary consumption of resources, especially in regions where water is scarce.
8. Hazardous waste due to replacement resin: The replacement resin must be specially disposed of due to the chemical contamination and must not be disposed of in normal waste.
9. Change in the taste of the water: Ion exchange changes the taste of the water. This is perceived as a disadvantage by many consumers.
10. Removal of valuable minerals: During the process, not only lime is removed, but also important minerals such as calcium and magnesium, which are beneficial to health.
11. Increase in metal aggressiveness and thus risk of corrosion due to the salt.
12. Regenerating salt is denatured and, in addition to accompanying substances such as clay, iron or potassium hexacyanofferate is added as a flow aid.

The regenerating salt is not harmless, as can be seen from the supplementary sheet:

• H290- May be corrosive to metals.
• H314- May cause skin and eye burns.
• H400- Toxic to aquatic organisms.
• P102- Keep out of the reach of children.
• P315- Get medical attention immediately if consumed.

Alternative solution: EVOdescale

EVOdescale uses natural malic acid complexes in the filter cartridge. This means that only the limescale in the water is bound and retained in the cartridge. The useful minerals such as calcium and magnesium remain in the water. This represents a significant difference to conventional water softening systems. In addition, this method does not change the taste of the water and does not add any substances such as sodium.

Advantages of EVOdescale compared to salt systems

• Complete water treatment: EVOdescale treats all the water without any risk of sodium or corrosion.
• No change in taste: Malic acid is a natural product that does not affect the taste of the water.
• Lime binding instead of conversion: In contrast to systems such as magnetizers or swirlers, the limescale is actually removed from the water.
• The binding of minerals to malic acid produces magnesium malate and calcium malate.
• No magnesium citrate, no magnesium sulfate, and no magnesium oxide. It's worth Googling yourself 😉 https://pubmed.ncbi.nlm.nih.gov/29679349/

In salt-based water softening systems, the water is mixed with untreated tap water for good reason. Ion exchange replaces calcium and magnesium ions with sodium ions. Complete softening to zero hardness is not permitted, as this would cause the sodium content in drinking water to rise sharply.

For this reason, salt systems must mix the softened water with raw water again in order to limit the sodium content. This addition of sodium is also considered corrosive, especially for pipes, fittings, and household appliances, and is a well-known disadvantage of traditional softening systems.

The Evodrop system operates without salt and without ion exchange. No sodium is added to the water. Therefore, no tap water needs to be added.

The bypass is set so that no mixed water is added.

100% of the water flows through the Evodrop system.

The advantage:

Unlike salt systems, the entire domestic water supply is treated evenly, without sodium, without blending, and without different water qualities at different taps. This ensures consistent limescale protection throughout the entire system.

Many suppliers of ion exchange water softening systems claim that their systems do not release salt into the water. This statement is chemically incomplete.

Salt consists of sodium chloride (NaCl). During the softening process, calcium and magnesium ions in the water are replaced by sodium ions. This exchange takes place via an ion exchange resin, which must be regenerated regularly with salt. This causes sodium to enter the treated water.

Ion exchange works according to the following technical principle:

• Ca²⁺ / Mg²⁺ → are removed
• Na⁺ → is introduced into the water

Softening without adding sodium is physically impossible in salt-based systems.

For this reason, in ion exchange systems, the softened water is often mixed with untreated raw water in order to limit the sodium content.

The operation of salt-based systems also produces saline regeneration wastewater. After its useful life, the ion exchange resin used is considered chemically contaminated waste and must be disposed of as hazardous waste.

In summary, it can be said that:

Water softened by ion exchange systems contains sodium, even if individual suppliers claim otherwise. The statement that "no salt is released into the water" is technically misleading. This statement could be interpreted as tongue-in-cheek or ironic.

Suppliers of water softeners often compare the addition of sodium with the salt content of a packet of chips. However, this overlooks the fact that people do not eat chips every day and that this comparison is misleading. It is similar to the argument for throwing PET bottles into lakes on the grounds that microplastics are already present there anyway.

It is important to understand that although the salt used in salt-based water softeners is originally a natural product, it is chemically processed and denatured for technical use.

Commercially available regeneration salt consists of at least 94% sodium chloride (NaCl). This salt is specifically made unfit for consumption for use in water softening systems. In addition to natural accompanying substances such as clay and calcium or magnesium sulfates, anti-caking agents are usually added to the salt, often iron or potassium hexacyanoferrate, to prevent clumping and ensure technical functionality.

Accordingly, regeneration salt is not table salt, sea salt, or Himalayan salt, but rather a technical salt that is expressly not intended for human consumption.
This is also made clear by the hazard and safety warnings required on the packaging, including:

• H412 – Harmful to aquatic life with long-lasting effects
• P102 - Keep out of the reach of children
• P315 / P101 – Get medical advice and show the label
• P410 - Protect from sunlight

These labels refer to the regeneration salt product itself and are part of the chemical classification. They indicate that this is a technical operating material used in water softening systems and that its handling and disposal are regulated.

It should also be noted that salt-based water softening systems produce salty regeneration wastewater, which enters the sewage system and can contribute to increased salt and chloride pollution. These effects have been the subject of environmental studies for many years.

Brief summary

The regeneration salt used in salt systems is not a foodstuff, but a chemically treated technical operating material with clear hazard labeling. Its use has technical side effects as well as environmental implications—a key difference from salt-free limescale protection systems such as Evodro.

There is no nationwide regulation against salt-based water softening systems in the USA, but several states, regions, and municipalities have enacted strict restrictions or bans—primarily for environmental and water management reasons.

1. Saline wastewater (brine) and environmental pollution

Salt-based water softeners work by ion exchange and produce salty wastewater (brine) during each regeneration cycle, which enters the sewage system and from there into natural waters and groundwater. This brine contains high concentrations of chloride and sodium, which can accumulate in water bodies.

In regions with sensitive freshwater ecosystems, increased salinity can worsen living conditions for aquatic organisms and plants.

2. Complications in wastewater treatment and reuse

Many municipalities are pursuing programs to reuse municipal wastewater, for example for irrigation or groundwater recharge. Salt-contaminated wastewater is problematic for such systems because existing wastewater treatment plants cannot remove sufficient amounts of salt.

This means that water that should actually be reused is no longer suitable for this purpose or requires costly post-treatment.

3. Local regulations and legal basis

Based on these environmental and water quality concerns, various authorities have enacted legal frameworks and regulations governing the use of traditional salt-based water softening systems:

• In Texas, a statewide ban on salt-based water softeners was introduced back in 2001; subsequent amendments now only allow them under certain conditions.
• In California, regional water authorities can issue local bans or restrictions on such systems under the California Water Code, particularly in regions that do not comply with salt/chloride contamination requirements.
• Other states such as Connecticut, Michigan, Minnesota, and Wisconsin have similar restrictions, some of which are linked to bans on brine discharge into sewage systems or programs to promote salt-free technologies.

In some local communities, water softening systems have even been completely banned and existing systems dismantled; inspections and enforcement measures are actively pursued in some areas.

4. Increased regulatory control in response to studies and practical effects

Studies have shown that rising salt and chloride concentrations in waterways and sewage systems cause serious ecological and technical problems:
Aquatic species are sensitive to salty water; studies indicate negative effects even at relatively low salt concentrations.

The costs and effort involved in sewage treatment plants and infrastructure are increasing because salt cannot be easily removed.

Conclusion

The restrictions and bans on salt-based water softeners in parts of the US are not based on health issues or medical arguments, but on water management, ecological, and wastewater engineering reasons:

• Brine discharge pollutes waterways and ecosystems.
• Salt-contaminated wastewater hinders water reuse and treatment processes.
• Regulatory authorities have used local powers to restrict or ban systems in order to achieve environmental goals and water quality targets.

In the affected regions, salt-free technologies or alternative water treatment concepts are therefore increasingly being used to avoid environmental pollution from saline wastewater.

Bad water due to softener

Since the 1970s, water softeners have been increasingly used in private households to decalcify drinking water. These devices may reduce the annoying cleaning work caused by limescale deposits, but their use is not always entirely unproblematic: softened water can cause galvanized pipes to corrode and be contaminated by microorganisms.

Research objectives and methodology

As the name suggests, softeners reduce the hardness of water. The total hardness of water is made up of the calcium and magnesium ions it contains. It is indicated in French degrees of hardness (°fH), for example. Softeners therefore do nothing other than replace calcium and magnesium with sodium. This prevents deposits (such as limescale) from forming because sodium salts remain dissolved in the water when it is heated. However, this tends to have a negative effect on the quality of drinking water as a foodstuff. Calcium is needed by the human body to build bones. Sodium, on the other hand, increases blood pressure in large quantities.

In 2016, the cantonal laboratory tested 23 randomly selected water softeners in private homes and schools. The drinking water was tested for bacteriological purity and chemical composition before and after the softener.

Samples and results

The good news is that water softeners reduce water hardness very efficiently. The bad news: the water is softened too much in many appliances. The test brings it to light: the total hardness of the softened water was below 15 °fH in 90% of the systems and even below 7 °fH in around half of them. Soft - i.e. low-limescale - water generally has a hardness level of around 10 to 15 °fH. Softening to around 15 °fH would therefore be sufficient in principle to prevent excessive scaling of fittings and appliances.

It is understandable that the installer sets a low residual hardness on the appliance; nobody wants to be accused of selling ineffective appliances. However, the customer buys disadvantages such as:

• an impairment of the taste of the drinking water
• high sodium content
• Increased corrosion of galvanized metal pipes (rust in the pipes is an indication of this).

The test brings another problem to light:

In 20 systems (85 %), the number of detectable microorganisms (bacteria and fungi) in the drinking water increased at least twofold. In 6 of the softeners (26 %), the legally stipulated maximum value for germs in drinking water was even exceeded by a factor of 3 to 600. This is a worrying result, as an increased bacterial count is not only associated with an impaired taste, but can also pose a health risk.

Assessment and summary

In principle, drinking water should only be softened if its hardness is above 30 °fH. If drinking water is softened, the appliance should be set so that a residual hardness of around 15 °fH remains in the water. Prevent contamination problems by placing the softener in as cool a location as possible, purchasing an appliance with a built-in disinfection device and having it serviced at least once a year. If water softeners are installed in the pipe network of rented apartments, the owner of the property is obliged under the Foodstuffs Act to ensure that the drinking water is not adversely affected by the water softener.

No. We do not change the pH value of the water through filtration with the EVOdescale.

The EVOdescale is a combination of house filter and descaling and is installed directly on the main cold water pipe in your house. It is important that a fixed installation sequence is followed. The EVOdescale must be installed after the water meter, the pressure reducer and the sediment filter (backwash filter).

No. To install the EVOdescale, you need certain specialist knowledge, which a plumber can provide. Certain conditions (water pressure, installation diagram, etc.) must be observed. We therefore recommend that the EVOdescale is always installed by a specialist (plumber). This guarantees safe installation and commissioning and you will be instructed by a specialist.

The maximum replacement period of 12 months is recommended for hygienic reasons.

Due to various external influences (house size, degree of hardness, water consumption, pipes, etc.), we will inform you of the maintenance interval individually.

EVOdescale guarantees a term of 12 months. Unless otherwise agreed in writing.

An EVOdescale replacement filter costs CHF 399. For an additional CHF 200, one of our service installers will carry out the maintenance for you.

Unlike softening systems with salt, where the guarantee only remains valid if the service is carried out by the supplier, Evodrop's guarantee remains valid for 20 years.

No. The EVOtransform is an optional addition to the EVOdescale or EVOadsorb softening systems and has no effect on the quality of the descaling process.

In the EVOtransform, the water is subjected to intense circulation at around 100,000 revolutions per minute by means of a patented rotating nozzle. This rotational movement creates a cluster of aligned water molecules, described in technical literature as a coherence domain. The water thus takes on a structured, hexagonal arrangement, also known as H3O2.

This physical agitation increases the internal surface area of the water. As a result, the water exhibits altered conductivity and solubility characteristics and displays a pronounced dynamic structure.

An additional advantage is the sensory change in the water after refinement. Many users describe the taste as lighter and fresher. The movement also allows the water to mix better with the ambient air after it exits the system.

The EVOtransform is maintenance-free and comes with a 20-year warranty. As an optional extension, it is an interesting addition for users who value additional physical water refinement.

SVGW is a recommendation and not an obligation.

Here you will find an explanation of why SVGW certification for Evodrop cannot be guaranteed by SVGW, despite the testable effectiveness via worksheet W512:

https://www.aquaetgas.ch/de/svgw-news/wasser/20150414-kein-svgw-zertifikat-mehr-f%C3%BCr-trinkwasser-nachbehandlungsger%C3%A4te/

It is important to understand that the system is FDA, ROHS and MOCA certified. This guarantees that no harmful substances are released into the water by the system.

The descaling was tested in the German DVGW laboratory in accordance with worksheet W512 and achieved a grade of 1, 100%.

For context: The Aqua Suisse Association is an association of interest groups in the field of water treatment.
The association is neither regulated by the state nor subject to legal requirements for manufacturers or suppliers. It is therefore a private interest group that represents the positions of its members.

In the public perception, attention is occasionally drawn to personnel overlaps between association functions and companies in the industry. Such constellations are not unusual in privately organized interest groups and allow every reader to form their own opinion about possible conflicts of interest.

The Aqua Suisse Association does not have an independent governmental or regulatory role.

Yes, EVOAdsorb filters out over 99% of short-chain PFAS & TFA from water – as verified by a Swiss laboratory.

Conclusion

The test results underline the excellent effectiveness of Evodrop AG in the filtration of PFAS.

While EVOdrink showed impressive reductions of up to 100% in several categories, EVOadsorb achieved complete removal (100%) in all substances tested.

The deliberate decision not to test long-chain PFAS is based on sound scientific findings that these substances generally already bind to surfaces or materials and can therefore be retained in upstream processes.

The results confirm the high quality and reliability of these filtration devices for use in water treatment.

The complete laboratory report can be provided upon request.

The descaling process used in EVOadsorb is based on the same operating principle as EVOdescale. Both systems use malic acid, which chemically binds the minerals that cause limescale. This is not a swirling or magnetization process, but genuine descaling, as proven in the German DVGW laboratory and awarded the top rating of 1.

The difference lies in the amount of malic acid used:

The EVOadsorb cartridge contains around 550 g of malic acid, while the EVOdescale cartridge contains around 1 kg of malic acid.

Due to these different amounts of active ingredient, the EVOadsorb cartridge achieves a limescale protection rate of around 80%, while the EVOdescale achieves a limescale protection rate of around 94%.

No. With EVOadsorb, all domestic water is treated directly—no need to add raw water.

The bypass is set so that 100% of the water flows through the system. This ensures that every tap in the house benefits equally from the limescale protection.

The EVOadsorb operates without electricity, without wastewater, and without additional regeneration cycles. There is no blending, as no dilution or correction of the water is necessary.

All water is treated completely and evenly—efficiently, consistently, and without side streams.

No, the EVOadsorb does not generate any wastewater and does not require electricity.

No. EVOadsorb is not a conventional activated carbon block filter, as is commonly available on the market.

Traditional activated carbon filters are manufactured using extrusion or compression molding. This involves compressing granulated or powdered activated carbon with binding agents (e.g., synthetic resins or polymer adhesives) into a block. This construction inevitably leads to a certain amount of pressure loss, a limited internal surface area, and an uneven pore structure.

The EVOadsorb works in a fundamentally different way:

Our carbon structure is built up on fiber-based carrier materials (e.g., rayon) using a wet spinning process, then carbonized, activated, and processed into a highly structured membrane. This process enables:

• an extremely high specific internal surface area (m²/g)
• a predominant formation of micropores ≤ 2 nanometers
• a uniform pore distribution
• Maximum adsorption density with minimal material usage

Conventional activated carbon filters, on the other hand, are mainly based on mesopores and macropores (10–50 nanometers and ≥ 50 nanometers, respectively), which allow flow but have a significantly lower selective adsorption capacity.

Sputtering technology – the decisive difference

Another technological difference lies in the sputtering technology used by Evodrop.

Functional layers in the nanometer range are precisely applied in order to optimize the adsorption and binding properties in a targeted manner. This process originated in the high-tech industry and enables controlled surface modification at the atomic level.

The result:

• targeted pollutant binding
• stable adsorption structure
• no material abrasion
• no channeling
• No relevant pressure loss in the system

The EVOadsorb therefore operates with high filtration efficiency and stable flow characteristics.

Proof of filter performance

The filtering performance of EVOadsorb has been tested and confirmed in independent laboratory tests conducted by SGS. The test reports document significant filtration of known pollutants under standardized conditions, including complete filtration of PFAS and TFA.

The complete test reports are available on request.

The EVOadsorb is a combination of house filter and descaling and is installed directly on the main cold water pipe in your home. It is important that a fixed installation sequence is followed. The EVOadsorb must be installed after the water meter, the pressure reducer and the sediment filter (backwash filter).

The replacement period of 6 to a maximum of 12 months is recommended for hygienic reasons. However, an early change within this period may be necessary if the water flow is noticeably reduced. This is not a defect in the filter used, but an indication of an increased occurrence of fine particles in the unfiltered water. Due to various external influences (house size, degree of hardness, water consumption, pipes, etc.), we will inform you of the maintenance interval individually.

Evodrop guarantees a term of 12 months. Unless otherwise agreed in writing.

An EVOadsorb replacement filter costs CHF 499. For an additional CHF 200, one of our service installers will carry out the maintenance for you.

Important information:

There are no additional costs for you. No electricity, sewage, maintenance contracts, or hidden costs.

No. We do not change the pH value of the water through filtration with the EVOadsorb.

You are welcome to contact us by telephone or e-mail. There is also a showroom available to show you the whole system and to test the water.

Our "activated carbon" is carbonized, activated and finally spun on membrane-like fibres, such as rayon, using the wet spinning process. In view of this, we can achieve brilliant results for the inner surface area (m2/g) compared to conventional activated carbon filters. Above all, our cartridges are predominantly based on micropores with a diameter of ≤2 nanometers. Conventional activated carbon is mainly based on meso- and macropores, which are significantly larger (10-50 nanometers and ≥50 nanometers).

In other words, the EvoAdsorb filters at 0.002 micrometers, while conventional activated carbon filters filter at 0.1 micrometers.
