Abstract
Air is fed to a cabin after having been purified to remove sulfur dioxide, nitrogen monoxide, nitrogen dioxide, carbon monoxide and hydrocarbons therefrom, e.g. to serve a space occupied by a human. According to the invention, an ozonizer is provided to generate ozone which is reacted with the sulfur dioxide and nitrogen monoxide to produce sulfur trioxide and nitrogen dioxide respectively. The pollutants are then taken up in part on sorption masses and the air is then heated before it is introduced into a catalyst mass wherein the carbon monoxide is reacted to form carbon dioxide. The carbon dioxide can then be absorbed and the purified air, after cooling, can be fed to the cabin.
