ABSTRACT:
A dust filter is surrounded by a frame and is held exchangeably in an air duct of a heating system or air-conditioning system of a motor vehicle and downstream of which an absorption filter may be arranged. For fitting an exchange of the absorption filter, the frame has an integrally formed edge or extension on the air-outlet side of the dust filter, which extension has latching openings into which hooks protruding resiliently from a retaining frame of an absorption filter are latched.
