The Pentek FloPlus-10BB (Item #455905-43) brings advanced FloPlus Series technology to a standard 10" Big Blue format, delivering outstanding 0.5-micron filtration efficiency while maintaining flow rates comparable to a much more open 10-micron cartridge. Its modified molded carbon block media, built with Pentek's Fibredyne technology, achieves true depth filtration with exceptionally low pressure drop, solving the flow restriction issues common with fine-rated carbon cartridges.

NSF/ANSI Standard 53 certified, the FloPlus-10BB mechanically reduces Cryptosporidium and Giardia cysts by 99.95%, while also providing strong chlorine taste and odor reduction — over 25,000 gallons of capacity at 2 GPM. Built for whole house carbon treatment in a 4.63" x 9.75" Big Blue housing, it delivers the dirt-holding life of a 10-micron carbon block with the particulate efficiency of a 0.5-micron filter, ideal for high-flow applications exceeding 25 GPM.

Sized to fit standard 10" Big Blue filter housings, the FloPlus-10BB is a strong choice for households wanting fine cyst-level filtration without sacrificing the flow rate needed for everyday whole house water use.
