The cartridge uses Pentek's proprietary Fibredyne carbon block technology to deliver fine 1-micron filtration with high flow rates and low pressure drop, rated for 5 GPM service flow. It's tested and certified by NSF International (via IAPMO R&T) to NSF/ANSI Standard 53 for PFAS and chlorine reduction claims, giving homeowners verified protection against emerging contaminants without sacrificing water pressure throughout the house.

Rated for a PFAS reduction capacity of 40,000 gallons and a typical filter life of about 12 months (depending on usage and water quality), the FloPlus Protect 20BB cartridge is designed as a direct replacement for the FloPlus Protect 20BB system, fitting standard 20" heavy duty housings with a 1" FPT inlet. Regular cartridge replacement ensures continued high-level PFAS and chlorine reduction for your entire home's water supply.
