2 Pk Pentek RFC-BB 25 Micron 10 x 4.5 Radial Flow GAC Cartridge 155141-43


2 pack Pentek RFC-BB  Radial Flow GAC Cartridge, 9-3/4 X 4.5, 25 Microns 


RFC Series cartridges are constructed with a 25 micron porous polyethylene outer shell and durable polypropylene end caps. The 23/4" OD cartridges have a polypropylene core and the 41/2" OD cartridges incorporate a spun polypropylene core. Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC).

The unique radial flow design offers the benefits of granular activated carbon (GAC) filtration, such as low pressure drop, while at the same time significantly reducing the release of carbon fines commonly associated with GAC style cartridges.

Radial flow cartridges are ideal for 'whole house' or other point-of-entry applications due to their high flow rate and low pressure drop compared to standard GAC and carbon block cartridges


  • Provides effective chlorine taste & odor reduction*
  • BB cartridges are ideal for point-of-entry (POE) and other high flow rate applications
  • Unique design reduces carbon fines in filtered water
  • Available in a wide variety of sizes
