Here's the solution to save water every time you use it! Simply replace your traditional aerator with a water-saving aerator tip. Our water-saving filter is a simple aerator consisting of a contoured core and a soft elastomer ring. The pressure in the supply network has the effect of compressing the elastomer ring which deforms and thus reduces the free passage for water. Thanks to the Venturi effect, an air intake follows, as well as a pressurized mixture of air and water. Thus, the water comes out of the tap with more pressure and more loaded with air! Thanks to these frothers, save money as well as save water!
