Why filter tap water? To reduce exposure to unwanted traces (chlorine, PFAS, metals), stabilize taste, limit limescale in your appliances, and encourage daily hydration at home and at the office. For families, it provides reassuring water for baby bottles, teas/infusions, and cooking, while avoiding plastic bottles.
4 combined filtration levels
Our system combines four complementary filtration levels:
- one sediment prefilter
- one coal & polyphosphate block (tastes/odors, chlorine, volatile organic compounds, and scale reduction),
- one 0.01 µm ultrafiltration membrane (bacteria, microplastics)
- and one UV-C sterilization (up to 99.9% of bacteria and viruses).
The result: healthy, clear, pleasant-tasting water that preserves essential minerals.
Complete transparency: Analysis results
Weengaged independent, recognized laboratories to ensure that the tests were as robust as possible (deliberate contamination followed by analysis).
Tests show near-total elimination of PFAS (PFOS, PFOA, PFNA, PFDA, PFBS ≈ -100%, PFBA ≈ -95%) and heavy metals ( lead, arsenic, etc.), as well as an absence of indicator bacteria after filtration.
Nearly 100% of PFAS and other pollutants filtered out!

Our filters are certified to NSF/ANSI standards, ensuring reliable purification and compliance with international safety standards.


Discover the results of our latest tests, focusing on PFAS
We have commissioned independent laboratories to test and quantify the effectiveness of our filtration system on per- and polyfluoroalkyl substances, more commonly known as PFAS. These particularly resistant compounds are already classified as "carcinogenic to humans"(PFOA) or "possibly carcinogenic to humans"by the International Agency for Research on Cancer (IARC).
