The Franklin FWIC Inline GAC Carbon Filter is engineered to deliver superior taste and odor reduction across a wide range of residential and light commercial water systems. Manufactured using high-capacity activated coconut shell carbon, the FWIC provides excellent adsorption performance, effectively removing chlorine, unpleasant tastes, and odors from incoming water.

Built for versatility, this inline filter installs easily into any 1/4-inch line, making it compatible with refrigerators, ice makers, RO systems, water coolers, beverage dispensers, coffee makers, RVs, campers, boats, and point-of-use drinking water systems. The FWIC is available in two configurations:
