The RFC Series cartridges are constructed with a 25-micron porous polyethylene outer shell and durable polypropylene end caps. The 2-3/4" OD cartridges have a polypropylene core and the 4-1/2" OD cartridges incorporate a spun polypropylene core. Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC).

Features:

• Provides effective chlorine taste & odor reduction (based on manufacturer's internal testing)
• Unique radial design reduces release of carbon fines in filtered water and low pressure drop commonly associated with GAC style cartridges
• RFC20-BB cartridges are ideal for point-of-entry (POE) and other high flow rate applications.
• Outer shell is a 70 micron porous polyethylene
