The filter of combustible dusts with a safety device (5) and hopper (2), which is mounted under the filter casing (1), is intended for collection of dusts that form an explosive mixture in mixtures with air. It comprises the hopper (2), which is displaced in relation to the plan of the filter case (1) at least on one side of the filter case (1). The safety device (5) is mounted in the free space (6) between the boundary frame of the casing (1) and overlapping frame (3) of the hopper (2), which results in rectification of the output of the pressure wave along the vertical wall of the filter case (1) upwards.<IMAGE>
