Water saving: Faucet aerator can completely mix the water and air flowing through the aerator to create a foaming effect, improve the rinsing power and reduce water consumption. The 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 flow Constant water flow: Faucet aerators ensure a certain water output when the water pressure is too low, limit the water output when the water pressure is too high, and stabilize the water output when the water pressure is unstable Anti-splash and noise reduction: The perfect airflow design in the faucet aerator, the hollow part of the filter element is mixed with air, and the water flow is gentle, the impact is reduced, the buffered water column is uniform, and the water column is vertical to prevent water splashing Package includes: 6 faucet aerators, 8 gaskets, 1 chrome-plated carbon steel faucet wrench
