Water Saving: Faucet Aerator 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 percent 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 certain water output when pressure water 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 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 water splashing Scope of delivery: 6 tap aerator, 8 seals, 1 steel tap wrench carbon chrome
