Cabin air filtration is one of the fastest-growing segments of the filtration industry, as the air quality in a vehicle’s cabin has never been more important. The vehicle’s cabin filtering system is a baseline in the prevention of airborne contaminants, including odors, fumes, mold, and smoke from entering the vehicle cabin. ACDelco multi-functional cabin filters will not only remove airborne solid contaminants from the air, but they can also absorb exhaust fumes and unpleasant odors.
