Key Performance Data
Construction & Materials
| Filter Media | Granular Activated Carbon (GAC) |
| End Caps | Polystyrene |
| Post-Filter | Spun Polypropylene (20 micron nominal) |
| Outer Casing | Polystyrene |
| Expansion Pad | Polypropylene (prevents channeling and bypass) |
| Support Basket | Permanently fastened to post-filter |
| Pressure Drop | 6 psi @ 2 GPM |
Where This Filter Works
The Pentek GAC-BB is designed for 10" x 4.5" Big Blue housings and serves as a general-purpose carbon filter in whole-house water filtration systems. It excels in applications where chlorine taste and odor reduction is the primary goal, and where loose granular activated carbon offers better contact time than carbon block alternatives. The full-length flow design ensures water passes through the entire carbon bed before exiting, while the internal expansion pad prevents channeling or bypass that can compromise performance. Ideal for municipal water supplies where chlorine and organic taste compounds are present, and compatible with standard Big Blue filter housings from Pentek and other manufacturers using the 10" x 4.5" format.
