Activated Coconut Carbon Filter Cartridge for the removal of chlorine and to improve the taste and odor of water. It's composed of a coconut-based granular activated carbon media and integral pre and post filter. This filter is designed to allow water to enter the bottom of the cartridge then filter through the entire carbon bed before exiting at the top. This maximizes contact time and thus the adsoprtion amount.
