Chloramine, Taste & Odour ReductionCRFC20-BB RADIAL FLOW CARBON CARTRIDGE The CRFC20-BB cartridge is ideal for chloramine taste & odor reduction in point-of-entry (POE) and other high flow rate applications Unique design reduces carbon fines in filtered water The CRFC20-BB cartridge is constructed with a 70-micron porous polypropylene outer shell and durable polypropylene end caps. The 41⁄2" OD cartridge incorporates a spun polypropylene-wrapped core. The bed of granular activated carbon (GAC) between the outershell and the core is specifically designed to significantly reduce chloramine taste and odor. The unique radial flow design offers the benefits of granular activated carbon (GAC) filtration, such as low pressure drop, while at the same time significantly reducing the release of carbon fines commonly associated with GAC style cartridges. The radial flow design significantly enlarges the pre and post filtration area of the cartridge for greater life versus standard upflow GAC cartridges. The CRFC20-BB cartridge is ideal for chloramine taste and odor reduction in point-of-entry (POE) and other high flow rate applications.
