Abstract

The invention relates to a method for producing a coated filter element (2), comprising the following steps: providing a filter body (4); and thermal spraying of a plastic material (30) onto the filter body (4) by means of an application device (32) such that the thermally sprayed plastic material (30) forms a porous and fluid-permeable surface filtration layer (28) on the filter body (4). The invention also relates to a correspondingly produced filter element.
