Compared to conventional aerators, it saves about 40% of water and energy while producing a pleasantly soft and splash-free stream. Thanks to its patented design, a significant amount of air is mixed with the water even at very low flow rates. Air that doesn't need to be paid for makes the water stream from the aerator pleasantly full and soft. The distinctive feature of the Long-Life aerator is the visibly coarse mesh sieve lens. This unique arrangement of the sieves ensures that only a small amount of water remains in the aerator after the faucet is turned off. As a result, scaling is effectively reduced, unlike conventional aerators where the slowly evaporating residual water inevitably leads to rapid and unhygienic scaling. Suitable for faucets with M24x1 internal threads.
