Eine Filtermatte für einen Luftfilter (1) insbesondere für Verbrennungsmotoren umfasst einen Faltenbalg (3) aus zu Taschen (6) gefaltetem Filtermaterial (12, 13) wie Papier, Vlies oder dgl., wobei zwischen den Taschen (6) des durchgehenden Filtermaterials (12, 13) zu gegenüberliegenden Seiten (10, 14) des Faltenbalgs (3) Hauptfalze (4) am Scheitel der Taschen (6) gebildet sind. Um eine beliebige Anpassung der Form der Filtermatte an den vorgegebenen Bauraum des Luftfilters zu ermöglichen, sind die Taschen (6) jeweils mit mehreren Querfalzen (8) winkelig angestellt zu den Hauptfalzen (4) gefaltet. A filter mat for an air filter (1), especially for internal combustion engines, comprising bellows (3) composed of filter material (12, 13), such as paper, fleece or the like, folded into pockets (6), main folds (4) being formed at the apex of the pockets (6) between the pockets (6) of the continuous filter material (12, 13) on opposite sides (10, 14) of the bellows (3). In order to enable any adjustment of the shape of the filter mat to the given construction space of the air filter, the pockets (6) are each folded with a plurality of transverse folds (8) at an angle to the main folds (4).
