Pentair Pentek RFC-20BB Big Blue Radial Flow Carbon Water Filter

About this item

• CLEANER, BETTER-TASTING WATER - Reduces chlorine taste and odor throughout your entire home so every tap delivers fresher-tasting water, using a deep bed of granular activated carbon (GAC).
• RADIAL FLOW CARBON DESIGN - Water flows radially through the carbon bed for a low pressure drop of just 0.90 psi at 4 gpm, while the design reduces the carbon fines commonly released by standard GAC cartridges.
• HIGH-CAPACITY WHOLE-HOUSE FILTRATION - Rated for more than 100,000 gallons of chlorine taste and odor reduction at 4 gpm, delivering up to about a year of whole-house service between changes.
• FITS ALL 20-INCH BIG BLUE HOUSINGS - Measures 20" x 4.5" and drops into any 20" Big Blue or other heavy-duty housing, replacing any 20" x 4.5" carbon cartridge. Ideal for point-of-entry and high-flow systems.
• NSF/ANSI 42 CERTIFIED BUILD - Tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements, with a porous polyethylene outer shell and polypropylene core rated to 125°F. Replace when taste or flow declines.
