Plumbeeze Carbon Block Cartridges are ideal for point-of-use (POU) and Reverse Osmosis applications. These cartridges can be used in a wide range of applications such as residential, food service, commercial, and industrial. The carbon block series cartridges are great for displacing traditional granular activated carbon and powdered activated carbon filters in application where high chlorine reduction is needed. They are manufactured with high purity activated carbon and provide an exceptional cost-to-performance value. These cartridges have high chlorine reduction, great dirt-holding capacity, and greatly reduced carbon fines.
