The 2-layer ABS hole filter effectively filters large particulate contaminants in the water flow. The 5-layer filter made of SUS 304 stainless steel effectively filters small particles in the water flow.

Non-toxic, rust-proof, wear-resistant, and shiny, robust and durable. Easy to Install: Installation requires no tools, making it incredibly easy. Simply tighten the economy aerator directly by hand or use an aerator wrench to tighten it. The included mounting wrench makes installation absolutely simple, even for the layman.

The abundant airflow design in the filter element allows air and water to mix completely, and then flows through the 5-layer SUS 304 stainless steel filter, generating abundant bubbles and draining the water. The water flow is fluid, smooth, and does not splash.
