For many years carbon media or expanded carbon, has been used for the reduction and removal of organic and inorganic gaseous pollutants. Expanded carbon or charcoal is produced using heat under high pressure that creates a surface area that has thousands of tiny openings that are capable of adsorbing gaseous molecules much higher in weight than the carbon itself. 

While carbon granules are often used in liquid filtration, the most common use is in air filtration whether in a stand alone filter or fan powered air filtration system. Carbon media filters have a fair amount of resistance and are therefore more often used in conjunction with a fan powered unit. 

Even though the expanded carbon has a high adsorption rate to weight of the carbon media, it will, over time, load up and stop adsorbing the odors or gases. Replacement cycles can be as long as once every 6 months to once every 6 weeks depending upon the severity of the gaseous pollutant.
