The Pentek GAC-20 made by Pentair is a 20" Granular Activated Carbon filter for chlorine taste and odour reduction. The design, with flows from bottom to top ensures a long contact time, allowing for maximum adsorption and treatment. Using a clean, acidwashed bituminous carbon with a large mesh size, this granular range is primarily a chlorine, taste and odour reduction cartridge with the advantage of a coarse 20 micron pre and post-filter pad to retain carbon fines that is not susceptible to blockage if high particulate is present.

Will fit most 20" Pentek style housings.
