Intelifil GAC-BB20C Compatible 20"x4.5" Granular Activated Carbon Filter
Granular activated carbon removes chlorine and organics through adsorption
High Surface Area
Granular activated carbon offers massive surface area for contaminant adsorption, targeting chlorine, volatile organic compounds, and dissolved organics that cause taste and odor issues
Flow-Through Design
Loose GAC media allows water to pass through at up to 4 GPM, providing contact time for chemical reduction while maintaining flow for whole-house or commercial applications
Big Blue Compatibility
20 inch by 4.5 inch dimensions fit standard big blue housings from Watts, Pentek, and other manufacturers using the Intelifil GAC-BB20C footprint
Wide Temp Range
Operates reliably in water temperatures from 40°F to 100°F, suitable for well water, municipal supply, and commercial installations with variable conditions
Direct replacement for Intelifil and Watts GAC cartridges
This IPW Industries cartridge is compatible with Intelifil GAC-BB20C, Watts FI-GAC020BB/3, and other 20 inch x 4.5 inch granular activated carbon filters used in big blue housings. Fits standard 20" housings designed for 4.5" OD cartridges. Works in whole-house systems, commercial filtration arrays, and well water treatment setups requiring chlorine and taste/odor reduction.
Replace based on water quality and usage
Municipal Water
For chlorinated city water with moderate usage, expect 6 to 12 months of effective chlorine and taste/odor removal depending on flow volume
Well Water
Well water with organics, tannins, or hydrogen sulfide may exhaust GAC capacity faster. Monitor taste and odor breakthrough as replacement indicator
Commercial Use
High-volume commercial applications with continuous flow require more frequent replacement to maintain consistent contaminant reduction
Chlorine Reduction
Removes chlorine and chloramines that dry skin, damage plumbing seals, and create taste issues
Taste & Odor Control
Adsorbs organic compounds responsible for musty, earthy, or chemical tastes and smells
High Capacity
7 lbs 6 oz of GAC media provides extended service life compared to thin carbon block cartridges
Drop-In Replacement
No modifications needed for existing 20x4.5 big blue filter housings from major brands
