The mask comprises a side-opening bag-type filter including: an inner filtering material having an open hole, which encompasses the mouth and the nostrils, and providing an inner filtering surface arranged to be spaced apart from the face of a wearer; and an outer filtering material connected to the inner filtering material to form a closed inner space that excludes the open hole, and providing an outer filtering surface that is opposite to the inner filtering surface.
