The invention relates to a filter arrangement for cleaning an air stream having at least three filter elements, wherein each filter element has a bellows made of pleated filter medium, wherein the filter elements are arranged in series and any two adjacent filter elements are connected to one another by means of a connecting tab. According to the invention, a fold run-out of all end folds of all bellows is oriented in a particular direction, the connecting tabs are of two different embodiments and the different embodiments of the connecting tabs are arranged alternatingly when viewed in a longitudinal direction of the filter arrangement. Not only is a simple installation of the filter elements in a filter holder thus facilitated but also a defined seating of the filter elements in the filter holder is ensured.
