Deep Filtration and IAPMO Certified

Independent testing confirms that this filter reduces PFAS, PFOA/PFOS, rust, lead, chlorine, heavy metals, chemical impurities, and sand, producing clean drinking water. Made from high BPA-free and lead-free materials, it also improves the taste and odor by reducing chlorine. The filter is certified by IAPMO against NSF/ANSI 372 and 42 standards. Please review the 42&372 certification on the IAPMO website.

Innovative Design

Only cold water should be used to power the filter. Its twist-and-lock construction and push-to-connect fittings enable quick and easy installation within three minutes, and three-second replacement. The system connects to 1/2" and 3/8" cold water pipes and faucets using a 3/8"-1/2" converter fitting, fitting directly into US sinks' standard 3/8" feed water valves.
