Abstract: A filter arrangement for a vehicle includes a flat filter element. The filter element has a filter medium and is integrated into an interior component of the vehicle. The filter element forms a surface facing an interior of the vehicle. In an embodiment, air flows through the filter element, and the air exits through the filter element into the interior of the vehicle.
