Abstract

An insert filter 10 for cleaning a gas stream, particularly for the intake air of an internal combustion engine or an air-conditioning unit, which includes a filter frame 11, a filter element 12 placed in the filter frame 11, and a shaft cover 13 and which is placed in the shaft 14 of a duct system 15 that guides the gas stream such that an unfiltered side 16 is separated from a clean side 17 by the filter element 12 and the filter frame 11. The shaft cover 13 closes a shaft opening 24 through which the insert filter 10 is inserted in the shaft 14. The filter frame 11 is connected to the shaft cover 13 so that the filter frame 11 can be removed from the shaft 14 without any need for additional removal aids by simply pulling on the shaft cover 13.
