ISpring Whole House Water Filter System w/ 20″ x 2.5″ Sediment & Carbon Water Filters, Clear 1st Stage Filter Housing, 3-Stage Whole House Water Filtration System, Model: WCB32C. The WCB32 whole house filtration system is the ideal “point of entry” filtration system for cleaning up water supplies to a home or business on municipal (city) water. Unlike “point of use” systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WCB32 filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WCB32. So what exactly do these three stages of filtration offer? Used as the first stage of defense on the system, the stage 1 housing holds a 5-micron high-capacity polypropylene sediment filter. This filter removes dirt and other various larger sized particles from the water that can clog the following filters. The second and third stages of the WCB32 house 5-micron CTO coconut shell carbon block filters. 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 filters knock out bad tastes and odors, combine to remove up to 99% of from the water, and are highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals. If you are on well water or have unusual contaminants in your municipal water supply, you may want to consider the WGB32BM or WGB32B-PB over the WCB32. For removing the common contaminants found in the majority of municipal water supplies however, the WCB32 fits the bill.
