Deep Filtration & Certification

Our filter efficiently reduces PFAS, PFOA/PFOS, rust, lead, chlorine, heavy metals, chemical impurities, and sand. It’s made with BPA-free and lead-free materials and certified by IAPMO against NSF/ANSI 372 and 42 standards. It successfully lowers lead when tested against NSF/ANSI 53 standards. Please check the certification on the IAPMO website using the "WD-10UA" search term.

Innovative Design

This filter is easy to install. It uses a twist-and-lock construction and push-to-connect fittings for a three-minute installation and a three-second replacement. The 3/8" line connects directly to US sink standard 3/8" water valves. For 1/2" and 3/8" cold water pipes and faucets, use the 3/8"-1/2" convertor fitting.

Clog-Free Filtration

We’ve increased the filtration area by 20X, significantly reducing the risk of clogging while improving filtration capability.

Upgrade your filter system with a UF filter or MZ filter to meet different water needs. Each system lasts up to 12 months or 8k gallons with municipal water, suitable for an entire household. Store unused filters in a sealed plastic bag in the refrigerator (not freezer) for up to 30 days.
