Water Saving: Faucet Aerator can completely mix the water and air flowing through the aerator to create a foaming effect, improve rinsing power and reduce water consumption. The faucet installed with a frother can save about 40% water. 7 Layer Filtration: Our faucet filter has 7 layers of fine filtration to ensure clean, hygienic and safe water. The 2-layer ABS perforated filter can effectively filter large particles of impurities in the water flow. 5 layers of SUS 304 stainless steel filter can effectively filter small particles in the water flow. Constant water flow: faucet aerators ensure some water outflow when the water pressure is too low, limit the water outflow when the water pressure is too high, and stabilize the water water outlet when water pressure is unstable. Splash-proof and noise reduction: The perfect design of the air flow in the faucet jet regulator, the hollow part of the filter element is mixed with air, and the water flow is smooth, the 'impact is reduced, the buffered water column is uniform, and the water column is vertical to prevent splashing water.
