Frequently asked questions

How does Evodrop descaling work?

Down arrow

Evodrop uses its own patented malic acid in the form of granules in the filter cartridge for descaling. Thanks to innovative ion sieve technology, Evodrop achieves a limescale protection rate of up to 94.2% without the use of salt, waste water or electricity. Unlike seed crystals, swirlers or magnetizers, the limescale is not converted but filtered out of the water. This means that the annoying limescale can be collected and processed in the filter cartridge. The minerals calcium and magnesium bind to the malic acid and do not separate even when the water is boiled at 200 degrees. This means that no more deposits can form. 3 grams of malic acid are released per 1000 liters of water. Malic acid is an organic component of many fruits, but is mainly found in apples. In this respect, it is completely neutral and tasteless. The filtration material in the EVOdescale filters heavy metals to protect against corrosion and eliminates bacteria and viruses from the water. It is important to understand that limescale is no longer in the water and limescale deposits can no longer occur. A DVGW-accredited laboratory and the internationally renowned testing institute CTI have tested the Evodrop system and were able to prove a limescale protection rate of over 94%. The filtration was verified by SGS, the largest test report in the world.

How good are descaling systems without salt?

Down arrow

In summary, it can be said that until now, alternative systems to the usual salt system have unfortunately not worked satisfactorily.
Evodrop, however, takes a completely different approach, as it is the only alternative to salt systems that also demonstrably removes limescale from the water.

Which is better a decalcification system without salt or a softening system with salt?

Down arrow

Basically, you have to understand that there are a wide variety of providers on the market and you cannot generalize this answer.
Unfortunately, most alternatives to salt systems are not very satisfactory, even though they have certain advantages for health and the environment, whereas salt has been proven to be harmful.
There are new solutions on the market, such as Evodrop, where thanks to the specially developed and patented malic acid complex, which in the form of granules in the filter cartridge, a limescale protection rate of up to 94.2% can be guaranteed without the use of salt, waste water or electricity. Unlike with seed crystals, swirlers or magnetizers, the limescale is not converted, but is instead eliminated from the water. The progress made by softening using malic acid makes it possible to leave the harmless minerals, such as calcium and magnesium, in the water. Obsolete softening systems with salt, on the other hand, cannot intelligently differentiate between useful minerals and troublesome limescale and are forced to remove both.

Why does the water taste different after softening with salt?

Down arrow

Because sodium is released into the water. In the ion exchange principle, the important minerals calcium and magnesium are exchanged with sodium ions.
As a result, the water can taste salty. The sodium content quickly reaches the legal upper limit in hard water. The chloride content remains the same.

Is salt released into the water in salt systems, ion exchangers, softening systems?

Down arrow

Yes, that is why it is called softening. The softening process works through an ion exchange in which calcium and magnesium ions are exchanged for sodium ions. This introduces sodium into the water, which can raise health concerns. An increased sodium content in the water can be problematic for people with certain health conditions, such as cardiovascular disease or high blood pressure. The use of salt in water softeners also has environmental implications. The salt and the chemical additives used to regenerate the resins end up in the waste water and can pollute the environment. The disposal of the exchange resin as hazardous waste also poses an environmental risk.

Is regenerated salt from salt plants dangerous for people or the environment?

Down arrow

Although regenerated salt from salt plants is a natural product, it has to be chemically processed. Commercially available regenerated salt consists of at least 94 percent rock salt or table salt, i.e. sodium chloride (NaCl). However, it has no place on breakfast eggs - the salt is denatured, i.e. made inedible by the addition of additives. In addition to natural additives such as clay, calcium or magnesium sulphate, iron or potassium hexacyanoferrate is usually added to road salt as an anti-caking agent. It is a regenerating salt with the following warnings on the packaging:
- H412 - Harmful to aquatic life with long lasting effects
- P102 - Keep out of the reach of children:
- P315 - Get medical advice/attention immediately
- P101 - If medical advice is needed, have product container or label at hand
- P410 - Protect from sunlight
Not suitable for human or animal consumption.
