Domestic water filter


Installing a drinking water filter makes sense, because it forms a barrier at point of entry of the water in the house for unwanted visitors. But what many people don't know: the installation of a DVGW-/ÖVGW-tested filter is even recommended according to DIN 1988! A domestic water filter ensures safety, hygiene and protection throughout your home.
