    Abstract: Provided is a mask apparatus. The mask apparatus includes a mask body which include a rear body and a front body coupled to a front surface of the rear body and in which a suction hole and a discharge hole are defined, a face guard coupled to a rear surface of the rear body so as to be in close contact with user's face and having a breathing space therein, and an air cleaning module mounted on the rear body to purify external air flowing into the suction hole and supply the external air into the breathing space. The face guard includes a coupling portion configured to face the rear surface of the rear body, a close contact portion that is in contact with the user's face, a connection portion configured to connect the coupling portion to the close contact portion so as to have a predetermined width in a front and rear direction, and a spaced protrusion configured to protrude from an outer surface of the connection portion so that at least a portion of the connection portion is maintained in a state of being spaced apart from the suction hole at both sides based on a center of a lower end of the front surface of the coupling portion.
