Pentek CBC-10 Carbon Block Filter Cartridge
The Pentek CBC-10 carbon block cartridge is positioned as a best-in-class point-of-use dechlorination solution because it combines fine particulate capture with high surface-area adsorption for rapid free chlorine and chloramine reduction. Compared with loose granulated media in this list, the CBC-10 delivers lower pressure drop and more consistent effluent quality at small scale, offering a lower upfront cost for cartridge replacement and simpler system integration for residential and light-commercial installs. Its technical advantage is tight micron-rated filtration plus uniform carbon dosing, which often reduces the need for downstream polishing or pre-treatment used with bulk catalytic media.
