  • Aqua Pure AP420 Water Filter Information:
  • The Aqua-Pure by Cuno AP420 water filter replacement cartridge reduces dirt and rust up to 5 microns. The AquaPure AP420 dirt & rust water filter cartridge is made from an exclusive process using pure white cellulose fibers. 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.
  • The Aqua-Pure AP420 is commonly used to prevent and protect hot water heaters from scale build-up which can decrease hot water efficiency up to 40%.
