Abstract
A mask apparatus includes a mask body including an air duct and a fan module mounting portion disposed at a suction-side of the air duct, a fan module disposed at the fan module mounting portion, and a mask body cover that is coupled to the front surface of the mask body and covers the fan module and the air duct. The mask body cover defines an air suction hole configured to communicate air with a fan inlet, and the fan module has a first end inserted into the air duct and a second end coupled to the mask body. The fan module mounting portion includes a fan module coupling portion that protrudes from the front surface of the mask body and that couples the second end of the fan module to the mask body.
