Pentek - RFC-BB - 10" x 4.5" Big Blue Radial Flow Carbon 25 Micron Filter

The Pentek RFC-BB is a 10" x 4.5" Big Blue radial flow carbon filter that uses granular activated carbon (GAC) to remove chlorine, taste, and odor from whole-house water systems. Rated at 25 microns with a 35,000-gallon capacity, this filter delivers superior GAC performance while virtually eliminating the carbon fines release common in standard loose carbon cartridges.

COMPATIBILITY & APPLICATIONS

Where This Filter Works Best

The Pentek RFC-BB is designed for point-of-entry (POE) whole-house systems and high flow rate applications requiring chlorine, taste, and odor removal. The radial flow design moves water from the outside shell through the GAC bed and into the polypropylene core, providing the adsorption benefits of loose granular carbon while the porous polyethylene outer shell contains carbon fines. This filter fits standard 10-inch Big Blue housings with 4.5-inch diameters and is ideal for municipal water supplies where chlorine removal and taste improvement are priorities. Compatible with Pentek and most major brand Big Blue filter housings rated for 10" x 4.5" cartridges.

💧 Pro tip: Radial flow GAC filters like the RFC-BB deliver cleaner water downstream than standard loose carbon cartridges because the polyethylene outer shell traps carbon fines before they enter your plumbing. If you've dealt with black water after changing GAC filters before, this is the solution.
