3M Aqua-Pure AP110 Whole House Filter

The 3M Aqua-Pure by AP110 water filter replacement cartridge reduces dirt and rust. The 3M Aqua-Pure AP110 dirt & rust filter cartridge is made from an exclusive process using spun polypropylene. 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.
