This Pentek GAC-BB drinking water filter cartridge reduces chlorine taste and odor and other unwanted tastes and odors in general water filtration applications. The filter medium consists of granular activated carbon for reduction of unwanted tastes and odors. The construction of the cartridge allows water to pass through the entire length of the carbon bed, while an internal expansion pad minimizes channeling, or bypass, ensuring maximum contact with the filter medium. A built-in 20-micron post filter reduces the presence of carbon fines and other suspended particles in the filtered water. This filter cartridge has an initial pressure drop of 6 pounds per square inch (psi) at a flow rate of 2 gallons per minute (gpm), and operates over a temperature range of 40 to 125 degrees F (4.4 to 51.7 degrees C). It is suitable for general residential and commercial water filtration applications.
