Abstract: 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.

Abstract: A filter element for filtration of an air stream includes: a folded filter medium forming a bellows, the filter medium being constructed at least in two layers and having a particle filter layer, an electrically conductive filter layer, and at least one edge band, the at least one edge band being connected to at least one outer side of the bellows. At least one further edge band is connected to an outer side of the bellows. The at least one further edge band is electrically conductive. The at least one further edge band forms a pocket open towards one side.
