9 3/4" x 2 1/2" Granular Activated Carbon Filter

GAC or Granular Activated Carbon is used for de-odourisation and palatability of water (Taste and Odour (TO))
The construction of the cartridge allows water to enter at one end and pass through the entire length of the carbon bed before exiting at the top of the cartridge, while an internal post filter pad helps reduce carbon fines and other suspended particles from the filtered water.
