Key item features

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.

About this item

Product details

Q. What is this filter used for? A. This whole house radial flow carbon water filter is designed for homeowners who want to reduce chlorine taste and odor while capturing larger sediment particles before water reaches household plumbing, appliances, and downstream filtration systems. Q. Who is this filter best suited for? A. It is commonly used by families and DIY homeowners focused on whole-house water quality, especially in homes supplied by treated municipal or city water where chlorine and visible sediment are present. Q. Where is this filter typically installed? A. This cartridge is installed at the point of entry on the main water line, commonly located in a basement, garage, or utility room, where incoming water is treated prior to distribution throughout the home. Q. How does radial flow carbon filtration work? A. Radial flow granular activated carbon allows water to flow from the outer surface toward the center core, helping support consistent flow performance while reducing chlorine taste and odor. Q. Is this filter suitable for well water systems? A. This filter may be used on well water systems when sediment levels are managed with appropriate pre-filtration. For higher sediment loads, installing a dedicated sediment pre-filter before carbon filtration is recommended. Q. Will this affect household water pressure? A. The radial flow design helps maintain steady water flow when installed in a compatible housing and operated within standard residential flow rates. Q. How often should this filter be replaced? A. Replacement frequency depends on water quality and household usage. Monitoring changes in water pressure, flow rate, or chlorine taste and odor can help determine when replacement is needed. Q. Are installation instructions included? A. This cartridge is designed for straightforward drop-in installation in compatible 4.5 x 20-inch housings. Installation guidance is typically provided by the housing or system manufacturer.
