Abstract
A filter in the inlet stream of a heating system or air-conditioning system of a motor vehicle for retaining noxious gaseous air components has the form of a tubular section which has air flowing through it transversely. The filter can be sealed at one end by a flap. For the purpose of rapidly implementable desorption with low expenditure, the filter be constructed from layered discs filled with activated carbon. The discs are separated from one another in each case by an intermediate layer consisting of material with good heat-conducting properties. The discs and the intermediate layers are clamped to each other by armatures penetrating the discs in the direction of the central longitudinal axis of the tubular section. The armatures, which have a heat-conducting connection to the intermediate layers, can be heated.
