Improve your water
Improving your water in Bettendorf
Compliant tap water doesn't mean ideal water. Two complementary levers: treat limescale (comfort, appliance lifespan) and purify drinking water (nitrates, pesticides, PFAS).
Water softener strongly recommended
At 50.0 °fH, the water is hard: limescale furs up water heaters and pipes and raises your energy bill. A softener typically pays for itself within 3 to 5 years.
Reverse osmosis — pure drinking water
Bettendorf, like all of Luxembourg, is a nitrate vulnerable zone, and the European PFAS standard has applied since 2026. An under-sink reverse-osmosis unit removes 95–99% of nitrates, pesticides, PFAS and residues — the safest solution for the water you drink.
