The Aqua-Pure AP811 water filter is a 25 micron polypropylene sediment filter. It features a gradient density. 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 Aqua-Pure cartridges are able to withstand high pressure drop and stressful conditions such as water hammer.
