Defend your under-sink drinking water against "forever chemicals" with the Pentek ChlorPlus Protect 10 replacement cartridge (Item #655226-43). Built for the ChlorPlus Protect 10 PFOA/PFOS Filtration System, this professional-grade carbon block cartridge is certified by IAPMO R&T against NSF/ANSI Standard 53 for the reduction of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) — reducing up to 98% of these persistent contaminants, and up to 99.6% of total PFAS when used as part of the complete system.

The cartridge delivers extremely fine filtration down to 1 micron using dense carbon block technology, addressing dissolved chemicals and fine particulate in a single pass while also providing premium sediment, chlorine, and chloramine reduction — giving you cleaner, better-tasting water right at the tap.

Rated for a 1,000-gallon capacity at a 1 GPM service flow rate, the ChlorPlus Protect 10 cartridge should be replaced approximately every 4 to 5 months, depending on incoming water quality and usage. It's a direct-fit drop-in replacement for the Pentair ChlorPlus Protect 10 system's 10" heavy-duty polypropylene housing with a 3/4" FPT inlet, and the housing's built-in pressure relief valve makes cartridge changes quick and hassle-free.
