PureEarth Non-Backwash Whole House Filter for Municipal Water

(Click her for our long-life automatic backwashing KDF/GAC whole house water filter)

WH-1 - Our original KDF/GAC whole house water filer (sold since 1989) unit connects to the main water line to filter the entire house - all faucets, showers, and baths will have clean, filtered water! The water first passes through a high-flow 1 micron sediment prefilter. This deep pleated cartridge has maximum filtration with minimum pressure loss (only 0.25 psi at 8 gallons per minute). Then the water enters the main tank where KDF and granulated activated carbon (GAC) remove chlorine, heavy metals (including lead), tastes, odors and chemicals. All the water in your home - kitchen, bath, showers, and laundry are filtered! The media filters approximately 300,000 gallons of water (about 3 years).

This whole house water filter unit will provide 99% chlorine removal at up to 6 gallons per minute. There is a 3 year prorated warranty on media, and 5 year full replacement on the hardware. The main tank is fiberglass reinforced with a polyethylene liner and is 7"X35". The prefilter housing made from polypropylene and is 7.25" X 14". Components are NSF listed and rated for pressures up to 125 psi. Both have 1" female pipe thread inlet and outlet, but can be adapted down to 3/4" plumbing. Since it requires cutting the main water line, a professional plumber may be needed. This whole house water filter is designed for primarily for municipal water that is free of iron and sulphur. Whole house water filter units are available for private wells - click HERE for more information.

Note on chloramines: To reduce the potential for the formation of THMs, some US municipal supplies are converting their chlorine (Cl₂) disinfection method to chloramines addition. Chloramines are chemical complexes formed from the reaction between ammonia and chlorine. They are more attractive to some municipal water suppliers because unlike chlorine, chloramines do not combine with organics in water to form THMs. While our standard KDF/GAC whole house water filter can effectively remove chlorine and much of the chloramines, chloramines require a greater contact time with regular carbon and so may not be entirely removed. Calgon Carbon manufactures a catalytic carbon called Centaur Catalytic Carbon, specifically made for chloramines removal, and it is highly effective. In addition to chloramines removal, it is also highly effective at VOC, taste and odor removal, and even hydrogen sulfide and iron removal in well water applications. If your water supplier is using chloramines as a disinfectant, you should consider our WH-1-CC option - it uses the catalytic carbon in place of the standard coconut shell carbon. If you are uncertain, simply call your water department.
