Water Saving: The faucet aerator can completely mix water and air flowing through the aerator to create a foaming effect, improve flushing power and reduce water consumption. Water faucets with aerators can save about 40% 7 layers of filtration: Our faucet filter has 7 layers of fine filtration to ensure clean, hygienic and safe water. The 2-layer perforated ABS filter element can effectively filter large particles of impurities in the water stream. The 5-layer SUS 304 stainless steel filter element effectively filters small particles in the water flow Constant water flow: The faucet aerator ensures a certain water flow when the water pressure 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: the perfect airflow design in the faucet jet regulator, the hollow part of the filter element is mixed with air, the water flow is smooth, the impact is reduced, the buffer water column is uniform, the water column is vertical, and water splashing is prevented Note: The picture is for reference only, please refer to the actual product , THANKS. ! !
