Product Description The 3M Aqua-Pure Whole House Replacement Water Filter Drop-in Cartridge AP811 has filter capacity that is ideal for homes with three or more bathrooms. This filter cartridge provides sediment filtration, and its grooved design increases total surface area, which can lead to longer cartridge life. This is a filter cartridge for a whole house water filter system, which helps protect pipes and appliances from sediment. From the Manufacturer The 3M™ Aqua-Pure® Water Filter Cartridge AP811 helps to reduce sediment particles as small as 25 microns in size, as well as rust, providing clearer water for drinking, bathing, laundry, and other household uses. 3M’s exclusive Micro-KleanTM XL progressive porosity technology forces water through pores that become increasingly tighter, filtering smaller and smaller microscopic particles. The unique process allows the cartridge to effectively reduce sediment while providing a high flow rate. The cartridge lasts up to six months before replacement.The cartridge is manufactured by 3M Purification Inc. (3MPITM), formerly CUNO Incorporated. It has a flow rate of up to 20 gallons/76 liters per minute. It operates at temperatures from 40-100°F (4.4-37.8°C) and water pressures from 25-125psi (172-862 kPa). It is for use with whole-house water filtration systems AP801, AP801-C, AP801T-C and AP801-1.5-C. The cartridge should be replaced every six months, or sooner if a noticeable reduction in flow rate occurs. Whole-house water treatment systems range from simple canisters with disposable filter cartridges to complex systems of tanks and filters for different contaminants. A system that includes a water softener may be bypassed by a cold drinking water line to provide salt-free drinking water. Whole-house systems are typically installed immediately downstream from water meters and well pumps, and thus may be referred to as point-of-entry (POE) systems. Depending on the filtration and treatment processes, they remove or reduce iron, sediment, chlorine odor and taste, and other chemical and biological contaminants. In doing so, they help protect plumbing and fixtures, reduce unpleasant tastes, colors and odors; and, in some cases, provide healthier water. Regular maintenance of a whole-house water filter system may be as simple as replacing a filtration cartridge every six months, or may require an annual service call. The initial expense of a whole-house water filter system often pays off in the long term, as it may protect pipes and fixtures from iron and/or hard water deposits and discoloration and provide savings in bottled water costs.For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals. Today the company, from its headquarters in St. Paul, Minnesota, serves industrial and commercial customers and consumers in nearly 200 countries. 3M Purification Inc.
