The Pentek FloPlus-10 (Item #455903-43) is a modified molded carbon block cartridge that delivers 0.5-micron filtration efficiency at the flow rate of a standard 10-micron cartridge. Using Pentek's enhanced Fibredyne carbon block technology, the FloPlus-10 achieves true depth filtration with exceptionally low pressure drop, making it ideal for applications where flow restriction has historically been a problem.

Tested and certified by NSF International to NSF/ANSI Standard 53, this cartridge reduces Cryptosporidium and Giardia cysts by mechanical means while also delivering strong chlorine taste and odor reduction — over 10,000 gallons of capacity at 1 GPM. Sized at 2.88" x 9.75" for standard #10 filter housings, the FloPlus-10 combines premium dirt-holding capacity with the particulate efficiency of a much finer-rated filter, extending time between cartridge changes.
