In recent years, concern for the health and comfort of vehicle occupants has increased dramatically. This has extended to concerns dealing with removing harmful and/or unpleasant odorous materials from air within the passenger cabin environment. Particulate filtration systems have been introduced, first in Europe, but now in the US, to remove airborne solids including soot and pollen, and auto makers are now addressing systems designed to additionally remove objectionable gases and vapors. Studies have shown that the auto cabin environment and the air surrounding the automobile contain a wide range of airborne materials. Considering this variety of materials, it is highly likely that activated carbon will be a component of any successful odor removal system. Activated carbon materials are capable of removing a wide variety of contaminants from cabin air streams. Conventionally, activated carbon removes odorous materials by means of physical adsorption.
