Pentek - GAC-10 - 10" x 2.5" Granular Activated Carbon Filter
GAC-10 Granular Activated Carbon Filter Cartridge
10" x 2.5" loose carbon filter with full-length bed contact and integrated 20-micron post-filter for whole house and RO applications
The Pentek GAC-10 uses a full-length granular activated carbon bed to maximize water contact time and adsorption efficiency. Built with an internal expansion pad to prevent channeling and a permanently fastened 20-micron spun polypropylene post-filter to reduce carbon fines, this cartridge delivers 5,000 gallons of chlorine, taste, and odor reduction at 1 GPM in standard 10-inch housings.
Engineered for Maximum Contact and Minimal Bypass
Full-Length Carbon Bed
Water enters one end and flows through the entire granular activated carbon bed before exiting, ensuring maximum contact time for effective chlorine and taste reduction
Internal Expansion Pad
Prevents carbon channeling and bypass, maintaining consistent flow through the media bed throughout the filter's service life
Integrated 20-Micron Post-Filter
Permanently fastened spun polypropylene post-filter reduces carbon fines and suspended particles before water exits the cartridge
Universal Fit
Standard 10" x 2.5" dimensions fit all common 10-inch filter housings for whole house and RO systems
Polystyrene Construction
Durable polystyrene end caps and outer casing with innovative support basket design ensure structural integrity and prevent post-filter bypass
Reliable Performance
Rated for 40°F to 145°F, 7 psi pressure drop at 1 GPM, and up to 5,000 gallons of service life depending on source water conditions
Where the GAC-10 Fits
The Pentek GAC-10 (part number 155109-43) is designed for standard 10-inch filter housings and works in both whole house and point-of-use applications.
