Product Information

The FiltersFast FF20GAC-20 is the correct compatible replacement for the Liquatec UDF-20BP 20" GAC Filter Cartridge. The FF20GAC-20 is granular activated carbon (GAC) coconut shell water filter replacement cartridge used to reduce the bad taste and odor of chlorine in a variety of low-flow applications such as under sink, counter top, and pre/post-reverse osmosis water filtration systems. This filter may also be used in some humidifying systems, recreational vehicle filtration systems, and food service applications.

The FF20GAC-20 GAC filter features coconut shell granular activated carbon (GAC) technology for more advanced water filtration, maximum chlorine absorption, and better tasting water. The coconut shell GAC design of these filters are some of the most effective water filtration media for the reduction of organic compounds such as chlorine, VOCs, radon, and other impurities. They are axial flow filters, meaning they are designed to force water to pass through the entire carbon filter media in order to ensure thorough filtration.

The FiltersFast FF20GAC-20 filter is a compatible replacement water filter cartridge with similar 20" GAC water filters including the Pentek GAC-20-BB, Pentek RFC20-BB, Watts GAC-BB20, Ametek GAC20-BB, Culligan RFC-BB-20, Whirlpool, US Filter, Ace, American Plumber, Bruner, Plymouth, Pentair, and other name brands. It will fit all water filter housings which use 20" x 4 1/2" filter replacement cartridges
