Features
- CLEANER, BETTER-TASTING WATER - Reduces chlorine taste and odor throughout your whole house using a deep bed of granular activated carbon, delivering fresher water to every tap.
- RADIAL FLOW TECHNOLOGY - Water flows radially through the carbon bed for a very low pressure drop, under 1 psi at 4 gpm, while significantly reducing the carbon fines common to standard granular carbon cartridges.
- 100,000 GALLON CAPACITY - Delivers more than 100,000 gallons of chlorine taste and odor reduction at 4 gpm, providing up to a year of whole house filtration before replacement.
- NSF CERTIFIED, FITS BIG BLUE - Tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements; fits any 20" x 4.5" Big Blue or heavy duty housing and replaces most 20-inch carbon cartridges.
- BUILT FOR HIGH-FLOW SERVICE - Ideal as a point-of-entry filter for high-flow whole house systems; replace every 6 to 12 months or when you notice a return of chlorine taste and odor.
