The AP811 by 3M Aqua-Pure water filter replacement cartridge reduces dirt and rust up to 25 microns. Cartridge is made from an exclusive process using polypropylene media. As water passes from the outer surfaces into the center of the cartridge, the filtering pores become increasingly smaller to remove even microscopic particles. Unlike string-wound and pleated paper cartridges, the rigid, sturdy construction of the 3M Aqua-Pure cartridges are able to withstand high pressure drop and stressful conditions such as water hammer. The 3M Aqua-Pure AP811 features easy cartridge changeout.
