Deep Filtration and Certification
Our filter efficiently removes PFAS, PFOA/PFOS, rust, lead, chlorine, heavy metals, chemical impurities, and sand through thorough purification. Certified by IAPMO against NSF/ANSI 372 and 42 Standards, it also reduces lead when tested by a third-party lab against NSF/ANSI 53 standards. Review the 42 & 372 certification on the IAPMO website using "WD-10UA".
Easy and Safe Installation
Designed for easy installation, our filter only requires cold water to operate. It features a twist-and-lock construction and push-to-connect fittings, making the installation process quick and straightforward. Connect it directly to your US sink's standard 3/8" feed water valves, and use the 3/8"-1/2" convertor fitting for 1/2" and 3/8" cold water pipes and faucets.
Clog-Free with Enhanced Filtration
Upgrade the filtration area to provide a 20x increase in dirt adhesion surface. This enhancement improves filtration effectiveness and reduces the risk of clogs.
Extend Filter Life and Reusability
Upgrade your filter system with a UF or MZ filter to meet different water needs. Each filter system can last up to 12 months or 8k gallons with municipal water. Store filters properly before vacations to ensure they stay fresh.
Given its affordable price, superior filtration, and easy installation, the WD-10UA is the right choice for clean, safe, and pleasant drinking water.
