Beschreibung
Zusammenfassung:	A ventilation arrangement for a heating and/or air-conditioning unit for a motor vehicle has a fan 12 for air exchange in the interior and a filter 18 for the adsorption of odorous and/or harmful substances contained in the air stream. The filter 18 is designed in such a way 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/or harmful substances and a gradual desorption thereof with a long time delay. The filter contains at least four plies of matrix-fixed active charcoal adsorbers, which may comprise a catalytic coating and the specific surface area, particle size distribution and micropore fraction in the carrier matrix have specified values. Prefilter 14 comprising a suspended-matter filter material and adsorber particles has similar characteristics. The arrangement is controlled by a sensor system 34.
