The 2-layer ABS perforated filter screen can effectively filter large particles of impurities in the water stream. The 5-layer SUS 304 stainless steel filter screen can effectively filter small particles in the water flow. Constant Water Flow: The faucet aerator ensures a certain amount of water flow. It reduces the water flow when the water pressure is too low, limits the water flow when the water pressure is too high, and stabilizes the water flow when the water pressure is too high and unstable. Splash and dust resistant. Noise Reduction: The perfect airflow design in the faucet jet regulator, the hollow part of the filter element is mixed with water.
