Abstract

A mask device includes a mask body including a front cover to form an outer appearance of the mask body, a frame coupled to the front cover, the frame located in front of a user's nose and mouth when the mask device is worn by the user, the frame including at least one inlet and at least one outlet located below the inlet, and a partition plate between the frame and the front cover, the partition plate forming an upper space and a lower space in the mask body. A first air cleaner is coupled to one side of the mask body and a second air cleaner is coupled to an other side of the mask body, where the first air cleaner and the second air cleaner filters outside air sucked in from an outside environment and supplies the filtered air to the mask body. The upper space of the mask body is in communication with the first air cleaner, the second air cleaner, and the at least one inlet, and the lower space of the mask body is in communication with the at least one outlet.
