1Water SavingThe faucet aerator can fully mix the flowing water and air to form a foaming effect, improve the flushing force and reduce the water consumption. A faucet with an aerator is installed about 30% less water than a faucet without an aerator. 2Splash-proof After the water flow is mixed into the air, the water source faucet aerator will become soft, reducing the impact force, which can prevent the water from splashing everywhere when the water comes out. 3Three-layer FiltrationThe faucet aerator is also a kitchen and bathroom faucet filter, with a built-in 3-layer filter, which can filter impurities well and ensure the hygiene and safety of the water. Suitable for kitchen and bathroom. 4Easy InstallationThe faucet aerator has a waterproof sealing ring on the outside, which can prevent water from splashing from the side. At the same time, 2 plug-in knob keys are included in the package to help tighten the bubbler, and the whole installation process is very convenient. 5Warm ReminderYou will receive 6 pcs M18.5 faucet aerators for replacing kitchen bathroom aerators and 2 keys. Depending on the water quality in different regions, for your water hygiene and safety, it is recommended to replace the aerator directly within 3-6 months.
