The 5-micron CTO coconut shell carbon block filter is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters, and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of sediment and chlorine from the water, and is highly effective on chemicals like pesticides, herbicides, and industrial chemicals. The second filter has an iron and manganese reducing filter - also great for the plethora of heavy metals found in well water sources. The FM25B iron and manganese reducing filter is only included with the iSpring WGB22BM (and WGB32BM), as it is not needed for most municipal water supplies that the WGB22B targets.
Our 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); it lasts up to 3 times longer than greensand
The filter set also removes sediment, chlorine, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants
Refer to our manual and our helpful videos for easy DIY installation; the 20 in x 4.5 in filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance
Our filter set fits standard 20 in x 4.5 in housings, including brand name models
The first stage high capacity polypropylene sediment filter is able to achieve filtration down to 5 micron; the second stage CTO carbon block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life
Both are tested by an independent third-party to meet NSF/ANSI standards; both filters have a capacity of 100,000 gallons of water, enough to supply a family of four with clean water for a full year

The cartridges are individually wrapped to ensure freshness; 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
