 Maintenance-free for up to 10 years. Automatic backwash prevents bacterial build-up and provides a continuously renewed surface area for filtration (plus, the drain/backwash water is completely safe and can be used for plants and gardening
). Maintains the flow rate and pressure you are used to. 
Complete installation information comes with every unit and is available online.

• The Highest Quality Available: Sixty-five (65) pounds or 2.5 cu.ft. of medical high-grade granular activated carbon (GAC) filtration media removes chlorine, chloramines, pesticides, lead, and other volatile organic compounds (VOC's), creating a healthy environment and improving the taste, clarity and odor of all your water. In use worldwide by children's hospitals, medical centers, health and fitness centers, high-end hotels, and personal homes.

The advanced digital valve head requires an ordinary electric outlet and consumes only the power of a doorbell.

• Inhibit Water Hardness without Salt Softening: EWS units help to solve problems associated with hard water (up to 30 grains) without the disadvantages of softening, salts, and chemicals. Prevents and inhibits scale build-up in pipes and water heaters, and makes it easier to wipe off and clean up water spotting
. Use less soaps and detergent
 and protect the warranty on your home's appliances
.

*Well Water Warning: Well water is required to have independent, complete and proper testing of your well water to determine the proper course of action in order to specify the correct system(s).

Water Hardness Caution: Physical conditioning can have a limited effectiveness with water hardness up to 500mg/l or 30 grains and greater. Similar to issues with softeners and ion-exchange, conditioning can be adversly effected by abnormal levels of pH, alkalinity, and/or silica. Please consult with your sales associate or EWS, Inc. to establish proper aesthetic expectations, helpful household hints, or a combination of product and your best alternatives.

Note: Any EWS unit can be combined with EWS softeners (hot-side only) and/or additional EWS sink filtration product based on customer preference or local water conditions.
