Abstract

An ambient air purification device has a filter device arranged in a filter receiving region of its housing. The filter device has a main filter element and a prefilter element, each having a circumferential frame device. A clamping force generating device is provided in the housing to exert an axial clamping force on the frame device of the main filter element resting, when mounted, at the frame device of the prefilter element. The clamping force is transmitted to the frame device of the prefilter element and presses the latter seal-tightly via a seal against a circumferential contact shoulder of the filter receiving region to seal the filter device in the filter receiving region. The frame device of the main filter element is sealed indirectly by the frame device of the prefilter element in relation to the housing and has no seal location of its own in relation to the housing.
