Get combined sediment and chlorine taste and odor reduction in one cartridge with the Pentek NCP-20BB (Item #155382-43). Built for standard 20" Big Blue filter housings, this cartridge is constructed from carbon-impregnated non-cellulose (pleated polyester) media, delivering sediment filtration alongside effective taste, odor, and chlorine taste and odor reduction — all in a single, versatile cartridge.

Unlike traditional cellulose cartridges, the NCP-20BB's non-cellulose media resists bacterial attack, making it suitable for both municipal chlorinated water and non-chlorinated well water applications. Its pleated design provides significantly more surface area than standard wound cartridges, giving it high dirt-loading capacity while maintaining minimal pressure drop — just 1 psi at 10 GPM — for strong flow even as the cartridge accumulates sediment.

Rated at a nominal 10 microns with a chlorine taste and odor reduction capacity of 1,000 gallons at 4 GPM, the NCP-20BB is an excellent choice as a polishing filter, in closed-loop streams, or as post-reverse-osmosis and well water filtration. It's NSF approved for material and structural integrity, making it a reliable, versatile option for residential, commercial, and industrial whole house systems.
