Abstract: A mask apparatus includes a mask body that defines a suction hole and a discharge hole, a face guard detachably coupled to a rear surface of the mask body by magnetic force, and an air cleaning module configured to filter external air and supply the filtered air to a breathing space. The face guard includes magnetic bodies disposed at a front surface of the face guard. The magnetic bodies include a first magnetic body disposed at a center of an upper portion of the front surface of the face guard, and a second magnetic body and a third magnetic body that are disposed at a lower portion of the front surface. The second and third magnetic bodies are spaced apart from each other and disposed at sides of a center of the lower portion of the front surface of the face guard, respectively.
