An innovative activated carbon cartridge using the wet spinning process with exceptional properties.
Thanks to a new type of membrane-like adsorption material made of woven activated carbon combined with a sputtering process, the Zenton S4 is currently the most innovative activated carbon cartridge for drinking water filtration. Manufactured in Switzerland using a patented wet spinning process, the Zenton S4 combines the classic properties of a premium activated carbon filter with an increased retention rate for heavy metals and protection against bacteria and viruses. The result is water of excellent quality and natural taste.
"Spun, sputtered - activated carbon rethought. A carbon innovation for water. So pure and natural, nature in every sip."
FAQ
- Have the filter cartridges been tested by an independent laboratory?Yes, the filter cartridges have been tested by various independent laboratories. You can find the tests in the expert reports on our website.
- What is special about the Zenton filter cartridge?They are a new development in the field of drinking water filtration made of woven activated carbon. Thanks to a patented production process, they offer above-average protection against pollutants in the water compared to conventional activated carbon block filters and are not only bacteria-proof but also virus-proof. In terms of filter performance, it stands out from the GFP cartridge particularly in the area of heavy metals. It can filter up to 99% of lead, cadmium and mercury. It works without the addition of chemicals or silver. The high filter performance and safety were tested by various institutes in Switzerland in 2022 using the latest measuring methods.
- Where are the filter cartridges manufactured?The cartridge is manufactured in Switzerland by Evodrop AG exclusively for LEOGANT.
- Can filtered pollutants be released again?No, so-called bleeding is conditionally not possible. Pollutants once retained in the cartridge are safely anchored in the structure of the cartridge and are not released back into the water even in the event of overloading.
- Does the cartridge filter lime?No. Minerals and trace elements are not filtered. This includes lime. It is involved in the taste of the water and stabilises the pH value. Water filters that remove lime either change the pH value, enrich the water with sodium or remove all minerals from the water. A LEOGANT filter system is designed to restore the natural balance of the water. Therefore, we do not remove limescale and concentrate on the combination of activated carbon filter and water vitalisation. This way, the water becomes comparably soft, as if it had been reduced by limescale, but remains fresh and pleasant in taste and does not need to be artificially manipulated.
- How can I dispose of the filter cartridge?Although our filter cartridges are predominantly made of activated carbon, they also contain some plastic due to their application. After 6 months of use, there are also varying concentrations of pollutants in the cartridge. Drinking water filter cartridges should therefore only be disposed of with household waste. In Germany, most household waste is incinerated and residual materials are disposed of properly.
Note on filter change according to DIN EN 806
We would like to point out that a filter change every six months is a prerequisite for the functionality and hygiene of the system. If the filter change is not carried out or is not carried out professionally, LEOGANT cannot guarantee the functionality of the water treatment system. The operator himself is liable for any contamination according to DIN EN 806/ DIN EN 1717.
