Accumulair Carbon 18x30x1 MERV 10 Odor Eliminating Air Filter (4 Pack)

A simple solution for controlling both odors and dust particles! Homeowners typically use a carbon air filter to help remove volatile organic compounds (VOCs) such as odors, smoke and/or gases from the air. Odorous gases and vapors are attracted to and held by the unique properties of the activated carbon media. Carbon is especially good at killing odors because of how it reacts with particles. The carbon activated media uses a process called adsorption. This causes gas molecules to adhere to the carbon. Once adhered, the gas molecules remain trapped in the filter and are unable to circulate back into the air.
