Big Blue 20″ x 4.5″ filter cartridges allow for minimal pressure reduction and extended filter life. CTO Carbon Block filter uses high-quality coconut shell carbon for maximum filtration efficiency and filter life. Iron and Manganese filter cartridge is effective on iron, manganese, and more. 1 input and output ports handle up to 15 gallons per minute. The WGB22BM whole house filtration system is an ideal “point of entry” filtration system for cleaning up well water. Unlike “point of use” systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB22BM 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. So what exactly do these two stages of filtration offer? The first stage of the WGB22BM 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 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 organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals. The second stage of the WGB22BM 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 WGB22BM (and WGB32BM), as it is not needed for most municipal water supplies that the WGB22B targets. If you are on municipal (city) water or a generally clean water supply, you may want to consider the WGB22B over the WGB22BM. For removing contaminants and heavy metals found in the majority of well water supplies however, the WGB22BM fits the bill.
