The invention relates to a filter bag for filtering fine particles from a gas, having a filter coating at least of a certain coating thickness, and at least one filter layer of a certain layer thickness that disposed downstream of the filter coating in the direction of the gas flow. The invention is based on the task of providing a filter bag having a low tendency to clog, thus improving the service life of the dust filter bag, particularly upon the filtering of fine dusts. The task is solved in that the coating thickness of the filter coating (1) is essentially larger than the coating thickness of the filter layer (3, 4) disposed downstream.
