The Aqua-Pure plastic whole house water filtration system reduces sediment or chlorine taste and odor (cartridge dependent) to help provide cleaner, clearer water by filtering out sediment and other contaminants from the water used throughout your entire home. The 3M Aqua-Pure water filter system is an ideal whole house water filtration system for larger homes and commercial buildings. It reduces particulate, rust, and the taste and odor of chlorine, improving the quality of cloudy, colored or musty water. By improving the clarity, taste, and odor of tap water, it provides an economical alternative to bottled drinking water. The filter system provides a heavy flow rate and is simple to install. The whole house water filter system, manufactured by 3M purification Inc., formerly CUNO Incorporated, is for larger homes and commercial applications. Installed at point-of-entry, the water filtration system has a single vessel design with 1-inch inlet and outlet ports. The system provides a flow rate of 20 gpm. It operates at water pressures up to 100 psi and operating temperatures up to 100 deg F. A pressure relief button is incorporated into the system for ease in cartridge replacement. 3M recommends replacement of the filter cartridge every six months at a minimum and regularly scheduled maintenance in order for the product to perform as advertised. The disposable filter cartridge must be replaced sooner than six months if a noticeable reduction in flow rate occurs. It should not be used with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Whole-house water treatment systems, sometimes referred to as point-of-entry (POE) systems, are installed immediately after the water meter or well pump. A whole house filter that reduces iron, particulate, and chlorine odor and taste will typically treat all water entering a residence, help protect plumbing and fixtures from rust buildup and discoloration while providing more appealing drinking water. If a water treatment system includes a water softener, a cold drinking water line may bypass the water softener to provide salt-free drinking water. Regular maintenance for a whole house system may be as simple as replacing a filtration cartridge every six months, or may require a service call. The initial expense of filtration often pays off in the long term as it protects pipes and fixtures while reducing or eliminating bottled water purchases.
