  • UNIVERSAL HOUSING FIT – This 20 x 4.5 inch iron and manganese reducing cartridge is designed to fit most standard 4.5” x 20” whole house filter housings used in residential point-of-entry systems.
  • CATION EXCHANGE RESIN MEDIA – Uses cation resin media beads that bind dissolved iron and manganese ions as water passes through, helping reduce staining-related minerals at the main water line.
  • IDEAL FOR STAINING-RELATED WATER ISSUES – Commonly used when iron and manganese contribute to orange/red or dark staining on fixtures, toilets, tubs, and laundry, helping improve whole-home water usability.
  • BEST USED WITH A SEDIMENT PRE-FILTER – Often installed after a coarse sediment stage to reduce particulate loading and help extend resin performance in well water or high-sediment environments.
  • SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement timing depends on iron/manganese levels and household usage; return of staining, reduced flow, or performance drop are common indicators to change the cartridge.
