water saving: Tap Aerator can completely mix water and air flowing through the fan to create a foaming effect, improve rinsing power and reduce water consumption. The faucet installed with a foamer can save around 40% water. 7-layer filtration: our faucet filter has 7 layers of fine filtration to guarantee clean, hygienic and safe water. The 2-layer ABS perforated filter can effectively filter large dirt particles in the water flow. 5 layers of SUS 304 stainless steel filter can effectively filter the small particles in the water flow. Constant water flow: faucet ariators ensure a certain water output when the pressure water is too low, limit 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 design of the air flow 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 splashing water.
