Pentair Pentek RFC-20BB Big Blue Carbon Water Filter, Whole House Heavy Duty Radial Flow Carbon Replacement Cartridge

The Pentair Pentek RFC Series Cartridges are constructed with a durable and porous 70-micron polyethylene outer shell, along with robust polypropylene endcaps. The 2-3⁄4" outer diameter cartridges feature a polypropylene core, while the 4-1⁄2" outer diameter cartridges incorporate a spun polypropylene core. Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC).

The unique radial flow design of the Pentek RFC Series Cartridges offers the benefits of granular activated carbon (GAC) filtration, such as low pressure drop, while significantly reducing the release of carbon fines commonly associated with GAC-style cartridges. These cartridges are available in a wide variety of sizes, making them ideal for point-of-entry (POE) and other high flow rate applications.

The Pentek RFC Series Cartridges are NSF International tested and certified, providing users with peace of mind. They are designed to reduce sediment and chlorine taste & odor, delivering great-tasting, clearer water. With a capacity of 100,000 gallons, these cartridges should be replaced every 1 year or when a drop in water pressure or water quality is noticed.

The Pentek RFC Series Cartridges are compatible with all 20" Pentair Pentek Big Blue or other 20" heavy-duty filter housings, and can replace any 20" x 4.5" carbon filter cartridge. The unique radial flow design of these cartridges allows for low pressure drop while significantly reducing the release of carbon fines, a common issue with GAC-style cartridges.

In summary, the Pentair Pentek RFC Series Cartridges offer a durable and reliable filtration solution, with a wide range of sizes and a capacity of 100,000 gallons. They are designed to reduce sediment and chlorine taste & odor, providing users with great-tasting, clearer water, while also being NSF International tested and certified for added peace of mind.
