The Pentek FloPlus-20 (Item #455904-43) extends FloPlus Series filtration into a 20" cartridge format, delivering 0.5-micron nominal filtration at flow rates comparable to a standard 10-micron carbon cartridge. Its modified molded carbon block media provides true depth filtration with low pressure drop, ideal for applications needing higher capacity without sacrificing flow.

NSF/ANSI Standard 53 certified for the mechanical reduction of Cryptosporidium and Giardia cysts, the FloPlus-20 also delivers strong chlorine taste and odor reduction — over 20,000 gallons of capacity at 2 GPM. Sized at 2.88" x 20" for standard #20 filter housings, it combines extended service life with reliable small-particle reduction for whole house and point-of-entry systems.
