Deep Filtration and Certification

Efficiently reduces PFAS, PFOA/PFOS, rust, lead, chlorine, heavy metals, chemical impurities, and sand through thorough purification. Made from high BPA-free and lead-free materials, this filter also removes chlorine taste and odor. Certified by IAPMO against NSF/ANSI 372 and 42 standards, and successfully reduces lead, as tested by a third-party lab against NSF/ANSI 53 standards.

Innovative Design

Designed for cold-water use only. Its twist-and-lock construction and push-to-connect fittings make installation quick and easy—finished in just three minutes. The 3/8" line connects directly to standard US sinks, and the 3/8"-1/2" convertor fitting accesses 1/2" and 3/8" cold water pipes and faucets.

Clogging Resistance

Upgraded filtration area provides a 20X increase in dirt adhesion, enhancing filtration capability while significantly reducing the risk of clogging.

Replacement and Long Lifespan

This filter system can be upgraded with UF or MZ filters to suit your water needs. Each system lasts up to 12 months or 8k gallons with municipal water, sufficient for an entire household. Store filters in separate sealed plastic bags in the refrigerator (not freezer) for freshness in 30 days.
