❄️ Recognized Certification - Food Grade Material Meets European EC1935-2004 Regulations, Australia Water Mark, TUV, ROHS, REACH, BPA FREE Certified. This kind of filter is recommended for tap water filtration. If your water source is well water, this filter may not achieve the filtering effect you expect.
❄️ Multi-Layer Density Tech - The whole house PP10 water filter is designed with density three PP layers to remove most particle and sediments. The inner layer is Absolute 5 microns; the middle layer is nominal 7 microns; while the outer layer is nominal 10 microns. The multi-layer density tech can capture impurities targetedly and have 30% longer service life than the other common type.
❄️ Higher Quality Filtration - CTO10 Carbon is well known for its unique absorbing ability, a pound of carbon is able to provide up 125 acres of filtering surface area. Our RO carbon filter is made of 100% pure coconut shell activated carbon block to remove most sediments, Sintering Technology ensures high absorbing capacity offers a much finer filtration of suspended particles and dirt.
❄️Compatible Models - The filter can be used in any standard 10” x2.5” RO Unit whole house filtration system and compatible with standard 10” x2.5” filter models of Dupont WFPFC5002, DGD Series, RFC, AP110-NP, AP101S, AP101T, Aqua Pure AP110, AP11S, AP11T, AP12S, AP1610, AP2610, AP51T, SS1-SS12, SS20-SS36, Culligan P5, P5-D, P5A, HF-150, HF-160, HF-360, GE FXUSC, Whirlpool WHKF-DWHV, WHKF-GD05, DuPont WFPFC5002, American Plumber WC34-PR and fits GE reverse osmosis filter systems.
