FIELD: cleaning gases, for example compressed air from water steam and oil mist. SUBSTANCE: filter includes supporting layer made from highly porous permeable cellular material of reticular core-type structure and filtering layer made from finely dispersed powder. Filtering layer is applied over entire outer surface of supporting layer having alternating projections and recesses. Hole provided in center of filter is used for evacuation of compressed air which enters it after passage through reticular cellular supporting layer. EFFECT: enhanced efficiency of filtration. 2 dwg
