Abstract
An air cleaning apparatus for vehicles includes an ozone generator, diffusing plate, and activated charcoal filter, which are disposed sequentially from the upstream side of air flow in an air cleaning duct. The activated charcoal filter contains acid treated activated charcoal and alkali treated activated charcoal. Thus, in the air cleaning apparatus for vehicles, the ozone generator oxidizes ammonia and acetaldehyde and then absorbs and removes the products by acid activated charcoal and alkali activated charcoal. As a result, ammonia, acetaldehyde and acetic acid which are bad odor components of cigarette smoke can be removed sufficiently and effectively.
