The WGB22BM whole house water filter system is an ideal “point of entry” filtration system for cleaning well water. Unlike “point of use” systems that are installed to supply water to a specific faucet, the WGB22BM whole house water filtration system filters your water from the source. This means water from every output in your home will have passed through the two filtration stages of the WGB22BM. The first stage of the WGB22BM whole house water filter houses a 5-micron CTO coconut shell carbon block filter. Block carbon is more effective than other forms of carbon in that it is finely ground carbon packed into a solidified block. This means it has a higher density than other types of carbon filters and is therefore more effective in removing targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes up to 99% of chlorine from the water, and is highly effective on industrial chemicals. The second stage of the WGB22BM has an iron and manganese reducing filter. The FM25B iron and manganese reducing filter is only included with the WGB22BM whole house water filter (and WGB32BM), as it is not needed for most municipal water supplies that the WGB22B model targets.


  • Protect your family and household appliances from iron, manganese and more: Our third stage whole house water filter (FM25B) is specially designed for iron and manganese removal, reducing iron (MAX 3.0 ppm down to 0.01 ppm) and manganese (MAX 1.0 ppm down to 0.01 ppm
  • This whole house water filter system 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. With 1″ NPT inlet / outlet and 20″ x 4.5″ filter cartridges, the whole house water filtration system has minimal impact on water flow (up to 15 GPM) and requires minimal maintenance
  • 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. This whole house water filter has a capacity of 100,000 gal. of water, enough to supply a family of four with clean water for a full year
  • The cartridges of this whole house water filter system are individually wrapped to ensure freshness. Please unwrap the cartridges before use
