A mask storage apparatus includes a body including an accommodation space in which a mask device is stored. A cover is rotatably connected to the body and is capable of opening and closing the accommodation space. A compartment extends from an inner surface of the body and partitions the accommodation space into a first accommodation space in which a part of the mask device is accommodated, and a second accommodation space in which a remaining part of the mask device is accommodated. The compartment includes a sterilization module to sterilize the mask device.
