They are designed to allow maximum contact between the water and carbon, ensuring optimal adsorption. The construction of the cartridge allows water to enter at one end and pass through the entire length of the carbon bed before exiting the other end of the cartridge, while an internal expansion pad minimizes channeling or bypass. Before the water exits the cartridge, a post-filter helps reduce carbon fines and other suspended particles from the filtered water. The post-filter is permanently fastened to an innovative support basket ensuring that it is firmly se d and eliminating any potential for bypass. GAC Series Cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration. ## Features - EFFECTIVE REDUCTION OF BAD TASTE & ODORS to provide good general-purpose drinking water - FITS ALL 10" Pentair Pentek Big Blue or other 10" heavy duty housings and can replace any 10" x 4.5" carbon filter cartridge - POST-FILTER HELPS REDUCE CARBON FINES and other suspended particles from the filtered water - NSF INTERNATIONAL tested and certified for your peace of mind - 12,500 GALLON CAPACITY.
