  • COMPATIBLE REPLACEMENT MODELS – This 5 micron 20 x 4.5 radial flow carbon filter is a replacement for Pentair EP-20BB, 155583-43, CB-45-2005 and fits most standard 20 inch x 4.5 inch whole house filter housings.
  • RADIAL FLOW GRANULAR ACTIVATED CARBON DESIGN – Radial flow carbon media directs water from the outer surface toward the core, supporting consistent contact time for chlorine taste and odor reduction while maintaining steady flow in whole house systems.
  • 5 MICRON SEDIMENT AND CHLORINE REDUCTION – Designed to capture fine sediment such as rust, silt, and visible particulate while also reducing chlorine taste and odor commonly present in treated municipal water supplies.
  • WHOLE HOUSE CARBON FILTRATION APPLICATION – Commonly installed at the main water entry point to support overall water clarity and reduce chlorine exposure throughout the home, while helping protect plumbing fixtures and downstream filtration equipment.
  • SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels, chlorine concentration, and household water usage. Monitoring pressure or flow changes helps determine when cartridge replacement is needed to maintain performance.
