Water saving: the faucet completely mixes the water and the air that passes through the aerator, creating a foam effect that increases flushing power and reduces water consumption. Faucets fitted with foaming units can save approximately 7 layers of filtration: Our faucet filters have 7 layers of fine filtration to ensure clean, hygienic and safe water. 2 layers of perforated ABS filters effectively filter large particles of impurities from the water stream. Constant water flow: The faucet aerator guarantees a certain water flow when the pressure of water is too low, restricts the water flow when the water pressure is too high, and stabilizes the water flow when the water pressure is unstable. Anti-splash and noise reduction: perfect design of airflow in the faucet jet regulator, the hollow part of the cartridge mixes with the air, the water flows smoothly, the impact is reduced, the column of buffered water is even and the water column is vertical to prevent splashing. Delivery includes: 6 foam taps, 1 chromed carbon steel tap key. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
