The water company reports total chlorine, which includes chloramine: the disinfectant that keeps the water safe to drink all the way to your tap.
LimescaleHigh259 mg CaCO3/lLow259 mg CaCO3/lLimescale inhibitor
Unfiltered tap water
Filtered with EcoPro
Hardness (calcium and magnesium) does not change when you filter, which is why the value is the same in both columns. The EcoPro filter contains a limescale inhibitor that stops those minerals from forming deposits in kettles, coffee machines, taps and pipes: the water is just as hard, but it no longer forms limescale.
