    Unfiltered tap water

    Filtered with EcoPro

    This zone is disinfected with chloramine instead of free chlorine, which is why free chlorine reads 0. The value shown is the chloramine: the disinfectant that keeps the water safe to drink all the way to your tap. It tastes and smells much less of chlorine than free chlorine does.

  • LimescaleLowLowLimescale inhibitor

    Unfiltered tap water

    Filtered with EcoPro

    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.

  • MineralsDrinkable96 mg/lDrinkable96 mg/lMinerals kept

    Unfiltered tap water

    Filtered with EcoPro

    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.

  • PFASWithin limit0 ug/LHigh quality0 ug/L

    PFAS are regulated by European drinking water law (EU 2020/2184, RD 3/2023) with a limit of 0.10 µg/l for the sum of 20 substances. Where no value appears, the water utility has not reported one.
