The Pentair Pentek C2 is a dual-purpose carbon water filter cartridge engineered for standard 5-inch housings. Its powdered activated carbon-impregnated cellulose media performs double duty, capturing fine sediment particles down to 5 microns while reducing chlorine, unwanted taste, and odor from residential water supplies. This compact cartridge measures 2.5" x 4.88" and drops directly into any compatible housing without adapters or modifications. With a chlorine reduction capacity exceeding 2,500 gallons at 0.5 gpm, the C2 delivers reliable performance between replacements. The filter operates in water temperatures from 40 to 125 degrees F and produces only 2 psi of pressure drop at 2 gpm, so water flow remains strong at the tap. Durable vinyl plastisol endcaps, polyethylene netting, and a polypropylene core provide dependable construction for everyday residential use. For best results, replace the C2 cartridge every three months or sooner if you notice a decline in water pressure or a change in taste. The C2 also serves as an effective polishing filter in process filtration or closed-loop applications where fine particle reduction and taste improvement are needed.
