• [Pure Water for Home] This big carbon filter cartridge is made of pure coconut shell charcoal block, wrapped in a food-grade polypropylene non-woven fabric to achieve fine water filtration while avoiding carbon particles leaking into the water. Tested by an independent third-party to meet NSF 42 Standards for material safety. [5 Micron Fine Filtration] Optimized to perform as both a sediment and carbon block filter, it filters out contaminants down to 5 microns, removes undesirable colors, bad tastes, the smell, and up to 98% of chlorine from well water and municipal water, significantly improving water quality for the whole house. [Low Pressure-Drop] Compared to the 1-micron filters, the 5-micron pore size helps prevent the cartridge from clogging before its adsorption capability is exhausted, maximizing the utilization of the carbon while maintaining a lower pressure drop. [High Capacity, Long Lasting] Our carbon filter can filter up to 15,000 gallons of water depending on usage and local water quality. Suggest replacing it every 3-6 months for the average household for optimal performance. [Wide Compatibility] Fits most of the big 4.5x10-inch blue and clear filter housings (approx. outer diameter 7″ at the top) and 10-inch whole house water systems including but not limited to: SimPure DB10, DB10P, GE GXWH35F, GXWH40L, HB18B, WGB21B, American Plumber W15-PR, W10-PR, AP801T, AP801B, HF45 series, etc. [Universal Replacement Filter Cartridge] The standard size makes our CTO filter an ideal replacement for sediment and carbon cartridges including FC15B, DuPont WFHDC8001, Watts MAXETW-FF975 WCBFF975, ClearChoice 84629, Liquatec CB-450-975-05, CTO2-HD10, Pelican CB-BB-10, WDGD-5005, AP817, PP10BB-CC, 155548-43 EP-BB EPM-BB CBC-BB, etc., Manufacturer: SimPure
