5-layer filtration This faucet filter features a built-in 5-layer filtration system, offering 2 additional layers compared to similar products on the market. This advanced filtration helps remove impurities and supports clean, safe water. Suitable for use with kitchen and bathroom faucets.Water saving of 30% to 40% The faucet aerator efficiently mixes water and air to create a non-splashing, foamy flow, improving water pressure feel while reducing consumption. A faucet equipped with this aerator can save approximately 30% to 40% more water compared to a faucet without one.Splash-proof, noise-reducing, consistent flow By blending air into the water stream, the flow becomes softer and less forceful, minimizing splashing during use. This provides a steady, smooth water flow while also helping reduce operational noise.Reliable sealing The faucet nozzle includes an external sealing ring to prevent side leakage. The package includes 2 installation wrenches for easy setup. Simply use the wrench to securely tighten the filter onto the faucet, ensuring a quick and hassle-free installation.Package contents You will receive 6 faucet aerators and 2 installation wrenches.
