Pentair Pentek RFC-20BB Carbon Water Filter, Whole House Heavy Duty, 20 x 4.5, 25 Micron

Pentek RFC Series Cartridges, constructed with a 70-micron porous polyethylene outer shell and durable polypropylene endcaps, offer a range of benefits for point-of-entry (POE) and other high flow rate applications. These cartridges come in a variety of sizes, with the 2-3⁄4" outer diameter cartridges featuring a polypropylene core, and the 4-1⁄2" outer diameter cartridges incorporating a spun polypropylene core.

Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC), providing the benefits of GAC filtration, such as low pressure drop. The unique radial flow design of the Pentek RFC Series Cartridges significantly reduces the release of carbon fines, a common issue associated with GAC-style cartridges.

These cartridges are NSF International tested and certified, ensuring peace of mind for users. With a 100,000-gallon capacity, they are recommended for replacement every 1 year or when a drop in water pressure or water quality is noticed.

The Pentek RFC Series Cartridges are designed to fit all 20" Pentair Pentek Big Blue or other 20" heavy-duty filter housings, allowing them to replace any 20" x 4.5" carbon filter cartridge. This versatility and compatibility make them a popular choice for a wide range of applications.

1. 70-micron porous polyethylene outer shell and durable polypropylene endcaps for robust construction.
2. Polypropylene core design for the 2-3⁄4" and 4-1⁄2" outer diameter cartridges.
