Due to the fact that the water collection container according to the invention is connected to the filter element or connectable, a comparatively simple maintenance of the filter device can be achieved because the water collection simply removed when replacing the filter element with and either disposed of together with the spent filter element or emptied and is connected to a new filter element. In particular, in the latter variant, the environmental compatibility of the filter device according to the invention can be further increased, since the water collection container can be connected almost as often with a new filter element and re-installed after emptying into the filter device.
