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 effectively reduce impurities and supports clean, safe water. Suitable for use with kitchen and bathroom faucets. Water saving up to 30-40% The faucet aerator efficiently mixes water with air to create a non-splashing, foamy flow, enhancing water pressure feel while reducing water usage. A faucet equipped with this aerator can save approximately 30-40% more water compared to a faucet without one. Splash resistant, noise reducing, constant flow By blending air with water, the flow becomes softer and less turbulent, minimizing splashing and noise. This provides a steady, smooth water stream for improved performance and user comfort. Reliable sealing design The faucet nozzle includes an outer sealing ring to help prevent side leakage. The package includes 2 installation wrenches for easy setup. Simply use the wrench to securely tighten the filter in place, ensuring a quick and hassle-free installation. Package includes 6 faucet aerators and 2 installation wrenches. Based on local water conditions, for optimal performance and water hygiene, it is recommended to replace the aerator every 3 to 6 months.
