About This
- COMPATIBLE REPLACEMENT CARTRIDGE – Designed as a replacement for Pentair RFC-BB, FXHTC water filter replacement cartridge, 155141-43, WRC25HD, RFC-BBSA, RFC-BBS-D, 48169, 155141, 1020705, 155141-27, 155141-30, 155141-51, RFC-BBS, TO8, and American Plumber W10-PR; suitable for most 10” x 4.5” water filter housings.
- 25 MICRON PRE-FILTRATION PERFORMANCE – A 25 micron rating is ideal for coarse sediment reduction, helping protect downstream filtration stages, plumbing components, and household water systems from debris buildup.
- RADIAL FLOW CARBON BLOCK MEDIA DESIGN – Uses radial flow carbon block construction to support higher flow rates while reducing chlorine taste and odor and helping capture coarse sediment and particulate matter commonly found in municipal and treated water supplies.
- 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 system performance.
- WHOLE HOUSE PRE-FILTRATION & SYSTEM PROTECTION – Commonly used as a pre-treatment filter to help protect plumbing lines, valves, appliances, and downstream filtration equipment from sediment buildup and chlorine taste and odor.
