Improving your water in Erpeldange

Compliant tap water doesn't mean ideal water. Two complementary levers: treat limescale (comfort, appliance lifespan) and purify drinking water (nitrates, pesticides, PFAS).

Limescale · advised

A softener improves daily life

At 21.6 °fH, the water is moderately hard. A softener protects your appliances, softens skin and laundry, and cuts down on descaling.

Drinking water · recommended

Reverse osmosis — pure drinking water

Erpeldange, 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.
