Pentek - RFC-20 - 20" x 2.5" Radial Flow Carbon 25 Micron Filter

The Pentek RFC-20 is a 20" x 2.5" radial flow carbon filter that delivers effective chlorine taste and odor reduction for up to 35,000 gallons in whole house and well water applications. Its unique radial flow design combines the performance of granular activated carbon with a 70-micron polyethylene outer shell to significantly reduce carbon fines while maintaining low pressure drop at high flow rates.

COMPATIBILITY & APPLICATIONS

Ideal Uses for the RFC-20

The Pentek RFC-20 radial flow carbon filter is designed for point-of-entry whole house filtration systems and well water applications where high flow rates and carbon fines reduction are priorities. It fits standard 20" x 2.5" filter housings and is particularly effective in applications requiring chlorine taste and odor removal without the carbon dust commonly released by traditional GAC cartridges. The radial flow design allows water to flow from the outside shell through the carbon bed and into the polypropylene core, maximizing contact time while maintaining low pressure drop. Recommended for municipal water supplies with chlorine, residential well systems, and any high-flow application where taste and odor control is needed.

💧 Pro Tip: The RFC-20's radial flow design significantly reduces carbon fines compared to standard GAC filters, but you may still notice a small amount of fine black particles during the first few minutes of use after installation. Run water through the filter for 3-5 minutes before regular use to flush any residual fines from manufacturing.
