Deep Filtration and Certification

This filter can efficiently reduce PFAS, PFOA/PFOS, rust, lead, chlorine, heavy metals, chemical impurities, and sand through thorough purification, providing clean drinking water. Made of high BPA-free and lead-free materials, it also reduces chlorine taste and odor. The filter is IAPMO certified against NSF/ANSI 372 and NSF/ANSI 42 standards, and can lower lead when tested according to NSF/ANSI 53 standards. For 42&372 certification, search for "WD-10UA" on the IAPMO website.

Easy Installation and Innovative Design

Only cold water should be used with this filter. Its twist-and-lock construction and push-to-connect fittings allow for a three-minute installation, three-second replacement, and safe integration. The 3/8" line connects directly to standard US sink water valves. The 3/8"-1/2" convertor fitting is used to connect to 1/2" and 3/8" cold water pipes and faucets.

Prevent Clogging with Enhanced Filtration

By increasing the filtration area, our filter now provides a 20X increase in dirt adhesion, enhancing filtration capability while minimizing the risk of clogging.

Filter Replacement and Long Lifespan

This filter system can be upgraded with a UF filter or a MZ filter to meet your specific water needs. Each system has a maximum service life of 12 months or 8k gallons when used with municipal water, which is sufficient for an entire household. Before going on vacation, store the filters in separate sealed plastic bags in your refrigerator (not freezer) to keep them fresh for 30 days.
