The Pentek TSGAC-10 is a specialty granular activated carbon and phosphate combo water filter cartridge designed to reduce bad taste & odor and chlorine taste & odor reduction while the phosphate crystals reduce rust stains and scale deposits. It has a built-in post filter to reduce the release of carbon fines. This 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. An internal expansion pad minimizes channeling or bypass. This design allows for maximum contact between the water and carbon, ensuring maximum contact between the water and the media. Before the water exits the TSGAC-10 cartridge, a 20-micron post filter helps remove 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 secured and eliminating any potential for bypass.
