Deep Filtration and Certification

This filter is designed to efficiently reduce PFAS, PFOA/PFOS, large-particle contaminants like rust, lead, chlorine, heavy metals, and sand. It’s made from high-quality, BPA-free, and lead-free materials. Additionally, it successfully reduces chlorine and improves taste and odor. The filter is IAPMO certified against NSF/ANSI 372 and NSF/ANSI 42 standards, and when tested by a third-party laboratory, it also lowers lead per NSF/ANSI 53 standards. For more details, use the term "WD-10UA" to view the 42&372 certification on the IAPMO website.

Innovative Design

Using only a cold-water source, the filter installs in just three minutes and supports a three-second quick replacement. Its twist-and-lock construction and push-to-connect fittings ensure safe and secure integration. The 3/8" line connects directly to US sinks' standard 3/8" feed water valves. For 1/2" and 3/8" cold water pipes and faucets, a 3/8"-1/2" convertor fitting is used.

Clog-Resistant Design

By enhancing the filtration area, this filter offers a 20X increase in dirt adhesion, significantly reducing the risk of clogging while maintaining superior filtration capabilities.

Filter Replacement and Long Lifespan

This filter system can be upgraded with a UF filter or a MZ filter depending on your water needs. Compatible with various filters, it provides a maximum service life of 12 months or 8k gallons when used with municipal water, ensuring it meets the needs of an entire household. For storage, place filters in separate sealed plastic bags and refrigerate them (not freeze) for up to 30 days.
