PureEarth Backwashing KDF/GAC Whole House Water Filter for Municipal Water

(click here to see our whole house filters for private wells)

How would you like to have "bottled-water" quality water at every tap in your home? Think of it: pure, filtered water for showers and baths (did you know that you adsorb chlorine and chemicals through your skin and inhale it with the steam?), filtered water right from your bathroom faucet for drinking and face-washing, filtered water right from your main kitchen faucet for drinking AND cooking (do you boil pasta in bottled water?), filtered water for your laundry! Whole house water filters make good economic sense!

The PureEarth backwashing KDF/GAC whole house filter provides chlorine-free and chemical-free water to the whole house for up to 700,000 gallons or 7 years! The "reverse flow" backwashing (done automatically) keeps the media free of fine sediment and silt, prolonging its life and enabling it to function at peak performance. The media can filter chlorine and chemicals effectively with flow rates up to 10 gallons per minute (the system can accommodate flow up to 20 gpm), with minimal pressure loss (less than 2 psi loss at 60 psi). All components are NSF certified. Call us for applications requiring higher filtering flow rates. We have been selling this backwashing unit for 6 years now - it is FIELD-PROVEN in real-world applications to be effective for a long time!

 Two medias are used in our whole house water filter - KDF-55 for dechlorination and heavy metal removal, and coconut shell Granulated Activated Carbon (or GAC) to remove taste, odors and chemicals, THMs, VOCs, DBPs, MTBE and other organic-based compounds. The KDF filter media is contained is a special 4-segment chamber that is attached to the riser tube. The water enters here first where the KDF filter media is swirled and fluidized, increasing the contact time with the water. The KDF filter media dechlorinates the water, removes heavy metals (including lead), and makes the entire water filter system bacteriostatic (prevents bacterial growth). KDF can also help reduce scale formation. Upon exiting the KDF chamber, it enters the activated coconut shell carbon to remove bad tastes and odors, chlorine by-products (DBPs, THMs, HAAs), and chemicals.

The Autotrol Performa 263/740 Logix control valve, with solid-state electronics, automatically backwashes the KDF and GAC water filter media (once a week in most conditions) to remove dirt and sediment and keep it in peak condition throughout its life. Sediment is also removed down to about 20 microns, and then is backwashed down the drain. For ultra clear water, we NOW include our SPF-1 high-flow sediment filter below as a post filter to go down to 1 micron - at NO EXTRA CHARGE! The valve is a true 1" valve but can also connect to 3/4" plumbing (choose 1" or 3/4" copper or PVC tail pieces to connect to). A integrated by-pass switch is included to allow by-passing the unit for uses not requiring filtered water (such as lawn watering). The unit stands about 60" tall and is 10" in diameter. Requires drain near by (floor, wash basin, overhead, etc.) and standard 110V outlet (uses less electricity than a night light).  Since it requires cutting the main water line, a professional plumber may be needed.

NEW IMPROVED DESIGN - REDUCES BACKWASH WATER BY 30%! -->

We have now incorporated the new Enpress/Vortech distributor that saves water, decreases pressure drop, and improves media cleaning! It eliminates the need for the gravel underbed all together, and secures the distributor pipe so that it stays in position. (Download a PDF spec sheet HERE.)
