Water saving: Faucet Foamer can completely mix water and air flowing through the aerator to create a foaming effect, improve flushing power and reduce water consumption. Faucet installed with aerator 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 flowConstant water flow: faucet aerators ensure certain water outlet when the water pressure is too low, restrict the water outlet when the water pressure is too high, and stabilize the water outlet when the water pressure is unstable Anti-splash and noise reduction: the perfect airflow design in the regulator of the faucet jet, 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 water splashing Note: The data is all measured manually, please allow 1-3cm error, due to the difference in light and display, there will be some difference of color, the actual object received shall prevail.
