The present invention relates to dust mask, is arranged so that the sewing laminated in contact with the face of the wearer and the endothelium to block the inflow of dust or dust to the outside of the endothelium of the fine dust or dust in the body and consisting of a shell to block the inlet, the mask comprising a strap earring respectively formed on both ends of the main body, But the sewing coupled to the endothelial form a space therein, is an open top filter bag which inlet is formed and, to be embedded in the interior of the filter bag, ocher, mugwort, any one selected from pine needles having antimicrobial properties of components are dyed in an aqueous solution containing at the same time having antimicrobial properties for harmful viruses, fine dust or cloth material of the antimicrobial filter to the dust collecting dust to be formed on the lower sides of the said body, one end is connected to the main body and the other end of the nose strap is connected to coma and dogs to prevent the coma of departure and, coma dog doedoe connected fixed with the nose ring strap, is my mouth to the nostrils of the wearer collecting fine dust particles entering the nostrils in in that as to features, Forming the filter bag to the body in contact with the wearers face, and by a built-in antimicrobial filter having antimicrobial properties for the virus to the filter bag, effectively collecting the particulate matter, dust and hazardous virus remaining in the air flowing through the body and removing, as well as to be able to provide the wearer with clean air, there is an effect capable of removing fine dust and particulates which may be introduced through the nose piece through the coma. In addition, separate the forces the endothelium and the outer covering of the body via the de-fogging means by the induction to the air to pass through the endothelium and shell separately and independently securing the smooth ventilation of air, is the endothelium and the shroud in cl
