LimescaleNot reportedLowLimescale 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.

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.

Coliform bacteria were detected in some samples during the period. They are an indicator of water quality, not a health limit: the rating is based on E. coli and intestinal enterococci, the health-based parameters. All results are in the full parameter list.

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.
