  The EcoPro filter contains a limescale inhibitor that stops the water's calcium and magnesium from forming deposits in kettles, coffee machines, taps and pipes. It doesn't remove those minerals, but limescale no longer forms. The hardness measured in your area is in the full parameter list.

  TAPP Water EcoPro filters do not remove healthy minerals such as calcium and magnesium, so the mineral content (total dissolved solids, TDS) is the same before and after filtering.

  PFAS are regulated by EU Directive 2020/2184, transposed into French law: 0.10 µg/l for the sum of 20 substances, applicable since January 2026. Where no value appears, the health inspection has not yet measured PFAS in this distribution unit.

The "Filtered" column shows the estimated result after filtering with TAPP Water EcoPro filters.
