IAPMO Certified Filter

Made from premium BPA-free and lead-free materials, the under sink water filter is certified by IAPMO against NSF/ANSI 372 Standard, ensuring reliable use from inside to outside. Certified by IAPMO against NSF/ANSI 42 Standard, the water filter can effectively reduce chlorine, taste, and odor. Tested by third-party laboratory against NSF/ANSI 53 standard, it can reduce lead. To view the 42&372 certification, please search "WD-15UA" on the IAPMO official website.

Easy Installation

The system should be connected only to a cold water supply. With innovative push-to-connect fittings, the entire installation process takes less than 3 minutes. The twist-and-lock design ensures that you can replace the filter in just 3 seconds. The system includes a 3/8” hose with a direct connection that adapts to standard 3/8’’ feed water valves under US sinks. The 3/8’’–1/2’’ convertor fitting helps you connect the system to both 1/2’’ and 3/8’’ cold water lines and faucets.

The fast and stable water supply provides pure and fresh water that tastes like spring water. The tested full flow rate is 0.75 gpm at 60 psi.
