A filter arrangement is suggested where the filter means (38) is placed between distance pieces (48, 50, 52). In order that the longitudinal edges (64, 66, 68) of the preferably zigzag-folded distance pieces cannot cause any damage to the filter means, they are provided with a substantially edgeless cap (90, 92, 94), of which the maximum width equals that of the distance pieces.
