A dust filter apparatus having at least one exchangeable, preferably essentially tubular, filter (52) which is tightly and detachably attached to a plate in the region of a recess, the plate being arranged in a housing and dividing a clean air side and a dust side of the filter apparatus, is characterised in that the plate (54) can be removed from the housing with the filter towards the dust side. As a result, dust is prevented from passing into the clean air side. <IMAGE>
