Abstract

A ventilation arrangement for the interior of a motor vehicle, having at least a heating or air-conditioning unit. The ventilation arrangement has a fan for air exchange in the interior and a filter for the adsorption of odorous and/or harmful substances contained in the air stream. The filter is designed so that, for the widest possible spectrum of odorous and/or harmful substances, a filter effect is produced which is based on rapid adsorption of the odorous and harmful substances and a gradual desorption thereof with a long time delay. A high short-term concentration of the odorous and/or harmful substances is thus converted by the filter into an extremely low but, instead, long-lasting emission which, with sufficiently extensive dilution, remains below a preset odor threshold or nuisance threshold.
