Quick Overview

Fits Pentek Big Blue and other heavy duty filter housings
5 2


The PENTEK-RFC-20 filter cartridge provides effective chlorine taste and odor reduction for 20-inch heavy duty housings. The cartridge combines a 70 micron outer shell and a bed of granular activated carbon (GAC) with a 25 micron spun polypropylene core for better filtration. The unique radial flow design reduces the release of carbon fines significantly when compared to other GAC filters. The RFC-20 filter is ideal for point of entry and other high flow rare applications.

  • Drop-in cartridge design allows for quick filter change on most 20-inch heavy duty housings
  • Radial flow design significantly reduces the release of carbon fines
