Abstract: A filter (50) that can be located on vehicles in the region of the relative wind has an inlet-side perforated sheet with slanted guide surfaces (5, 7), a preliminary filter (9), a coarse dust filter (23), a first fine dust filter (27) with a free space (25) between the coarse dust filter (23) and the fine dust filter (27), a second fine dust filter (31) with a free space (29) between the fine dust filters (27, 31) and, on the air exit side, another perforated sheet (33) with slanted guide surfaces (35). With this filter, when vehicles, especially motor vehicles, are traveling on roads, there is effective filtering of dust, especially also fine dust, from the air that is flowing through the filter (50) under the action of the relative wind.
