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.

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.
