Key Features
- COMPATIBLE REPLACEMENT MODELS – This 25 micron 20 x 4.5 radial flow carbon filter is a replacement for Pentair RFC20-BB, RFC-20BB, SDP-4520, 155247-43 and fits most standard 20 inch x 4.5 inch whole house filter housings.
- RADIAL FLOW GRANULAR ACTIVATED CARBON DESIGN – Radial flow carbon media allows water to pass evenly through the cartridge, supporting higher flow rates while reducing chlorine taste and odor and capturing coarse sediment commonly found in treated municipal water.
- 25 MICRON PRE-FILTRATION FOR WHOLE HOUSE SYSTEMS – Designed to capture larger sediment, grit, and particulate matter before finer filtration stages, helping protect plumbing lines, valves, appliances, and downstream filtration equipment.
- SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels, water quality, and micron rating; finer filters capture smaller particles more quickly, so monitoring flow or pressure changes helps determine when cartridge replacement is needed.
- IDEAL WHOLE HOUSE PRE-FILTER – Commonly used as a first-stage or main entry point sediment filter to help protect plumbing, appliances, water softeners, and carbon filters from sediment buildup and premature wear.
