Water saving filters sold by 3

This water-saving filter is a frother consisting of a profiled core and a flexible elastomer ring. The pressure of the supply network has the effect of compressing the elastomer ring which deforms and thus reduces the free passage for water. By the Venturi effect. The Venturi principle is based on hydraulic operation which injects pressurized air into the water. Easily save up to 40% water and the energy needed to produce hot water. Simply replace your traditional frother with a water-saving aerator nozzle. Set of 3 filters
