## Overview

The 3M Aqua-Pure AP811 is a high-capacity whole-house replacement water filter cartridge designed for AP800 series systems. It reduces sediment particles as small as 25 microns, features a grooved surface for extended cartridge life, and supports a flow rate up to 76 liters per minute. Ideal for homes with three or more bathrooms, it ensures cleaner water for all household uses and requires replacement every six months to maintain optimal performance.

## Description

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. (formerly CUNO Incorporated), provides filtration and separation solutions for food service, science labs, residential, marine, and other applications. The 3M brand, across thousands of products, represents consistency, superior quality, and value.

Review: High Quality Filter - High quality water filter!. I have been using this brand of filter for years and they work very well and hold up great. The design allows particles to be trapped while still allowing good water flow through them. I changed over from the 25 micron to this 5 micron to get better filtration. It states the water flow is the same, 20 gpm. Once I replace my old 25 micron filter, I'll see if the flow rate remains the same or not with the micron filtration difference. It will be an interesting comparison and I'll see if I can update this review after a few months of use.
Review: Great filter that lasts months before needing to be replaced. - We've using this specific water filter for years and cant complain about how well these water filters are made. It is suggested to change these filters out every 6 months but if you miss a month, these filters still do a terrific job. Its amazing when cleaning the filter to see how dirty city water can really be. By using these filters, I know that I'm getting a quality filter that will last month and is reasonably priced. The filter is extremely easy to change out and requites no more than a couple of minutes to replace and install the new filter. There is currently nothing that I would change about the quality of these filters and I highly recommend these filters to anyone looking for a replacement filter that meets the specifications listed.
