Abstract
A device for removing noxious and aromatic matter from a conducted air flow into the interior of a vehicle comprises an air conduction housing with a reactor containing an adsorbent. To attain consistently good adsorption and absorption power with small amounts of adsorbing and absorbing material, the air conduction housing is designed with two separate parallel air flow channels, in each of which there is a reactor in the form of a flat wall. An adsorption air flow acts upon the adsorbent in one air flow channel and a desorption air flow acts upon the adsorbent in the other air flow channel, the direction of air flow into the reactor in the adsorption operation being opposite that in the desorption operation.
