[Deep Filtration and IAPMO Certified] Based on independent testing, this filter efficiently reduces PFAS, PFOA/PFOS, large-particle contaminants such as rust, lead, chlorine, heavy metals, chemical impurities, and sand through thorough purification for clean drinking water. The filter is made of high BPA-free and lead-free materials and can successfully reduce chlorine, taste, and odor. This filter is certified by IAPMO against NSF/ANSI 372 and NSF/ANSI 42 Standards. It can lower lead when tested by a third-party laboratory against NSF/ANSI 53 standards. Please use the "WD-10UA" search term to review the 42&372 certification on the IAPMO website.

[Innovative Design] Only a cold-water source should be used to power the filter. Its twist-and-lock construction and push-to-connect fittings enable installation in three minutes, a three-second replacement, and safety-assuring integration. This filter comes with a 3/8" line that connects directly to US sinks' standard 3/8" feed water valves. The system is connected to 1/2" and 3/8" cold water pipes and faucets with the use of the 3/8"-1/2" convertor fitting.

[Solve Clogging Problem] By upgrading the filtration area, our filter now provides a 20X increase in dirt adhesion area, enhancing filtration capability while minimizing the risk of clogging.

[Filter Replacement and Long Lifespan] This filter system may be upgraded with a UF filter or a MZ filter to meet your water needs. It is compatible with several filters with various functions. Each filter system has a maximum service life of 12 months or 8k gallons when used with municipal water, which is sufficient to cover the needs of an entire household. Before going on vacation, please put the filters in separate sealed plastic bags and store the bags in your refrigerator (NOT the freezer) to keep them fresh for 30 days.
