iSpring F2WGB22BM 4.5” x 20” Whole House Water Filter Replacement Set - One Carbon Block Cartridge and One Iron & Manganese Reducing Cartridge - Fits WGB22BM (F2WGB22BM)
  • [Protect Your Family and Household Appliance from Iron, Manganese, and More] Our filter (FM25B) is specially designed for iron & manganese removal, reducing iron (MAX 3.0 ppm down to 0.01 ppm) and manganese (MAX 1.0 ppm down to 0.01 ppm). It lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. The filter pack also removes sediment, chlorine, rust, industrial solvents, and various other contaminants.
  • [DIY Installation and Maintenance] Refer to our manual and our helpful YouTube videos for easy DIY installation. The 20” x 4.5” filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance. Our filter set fits standard 20” x 4.5” housings, including brand name models.
  • [Top-Notch Quality] The first stage CTO Carbon Block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. It is tested by an independent third-party to meet NSF/ANSI standards. The filter has a capacity of 100,000 gallons of water, enough to supply a family of four with clean water for a full year.
  • [Peace of Mind Customer Service] Register online to activate your manufacturer warranty and life-time free tech support from U.S. local support team. We stand behind our products and if you encounter any problems with any of our products please reach out to us immediately. We are happy to help!
  • [Please Note] The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. For well/pond water with very high iron/manganese please contact us for customized solutions. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
