A softener improves daily life
At 19.7 °fH, the water is moderately hard. A softener protects your appliances, softens skin and laundry, and cuts down on descaling.
Reverse osmosis — pure drinking water
Garnich, 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.
