A filter device is disclosed. The filter device includes a coalesce and a final separator arranged one after another in a flow direction. The final separator includes final separator material and is arranged radially within the coalesce. The coalesce is configured hollow-cylindrical and includes a coalescer material and an external support structure with an upper coalescer ring and a lower coalescer ring that are connected with one another via axial coalescer ribs. A positioning element is provided on the final separator. A positioning opening is provided in a region of the at least one lower coalescer ring. The positioning opening is configured in a complementary manner to the positioning element and the final separator engages into the positioning opening in a mounted state with the positioning element and thereby aligns the final separator relative to the coalesce.
