Pentek - CBC-20BB - 20" x 4.5" Big Blue Carbon Block Filter 0.5 Micron
CBC-20BB 20" x 4.5" Big Blue Carbon Block Filter
The Pentek CBC-20BB uses bonded powdered activated carbon (PAC) in a solid block structure to reduce chlorine taste and odor while filtering sediment and cysts down to 0.5 microns. Rated for 150,000 gallons at 4 GPM, this 20" x 4.5" cartridge fits standard Big Blue housings and handles whole-house flow rates without excessive pressure drop. Manufactured entirely from FDA-compliant materials using a patented process that ensures consistent performance across residential, commercial, and food service applications.
Why the CBC-20BB Outperforms Standard Carbon Filters
Cyst Reduction
Reduces Giardia, Cryptosporidium, Entamoeba, and Toxoplasma cysts along with fine sediment particles down to 0.5 microns
Bonded PAC Structure
Patented carbon block construction provides consistent filtration and superior chlorine reduction compared to granular carbon
High Flow Capacity
Handles up to 4 GPM with only 8.5 psi pressure drop, suitable for whole-house and commercial installations
Big Blue Compatible
Fits all standard 20" x 4.5" Big Blue housings with polystyrene end caps and polyethylene netting for durability
Wide Temp Range
Operates reliably from 40°F to 180°F, suitable for both cold and warm water applications
FDA Compliant
All materials meet FDA requirements for potable water contact, safe for drinking water and food service use
Where This Filter Works
The Pentek CBC-20BB (also known as part number 155312-43) is designed for 20-inch Big Blue filter housings with 4.5-inch diameter capacity. It works as a primary whole-house carbon filter, a polishing filter after sediment pre-filtration, or a pre-filter before reverse osmosis membranes and other fine filtration stages. Common applications include residential well water systems, municipal chlorine removal, commercial food service equipment protection, and industrial process water treatment. Compatible with Pentek, US Filter Works, Hydronix, and other manufacturers' 20" x 4.5" Big Blue housing systems.
Pentek has been manufacturing water filtration components for over 40 years, and the CBC series remains the standard for carbon block reliability in whole-house applications.
