Mask manufacturing method, mask and mask manufacturing combination

A mouth protector manufacturing method, a mouth protector and an mouth protector manufacturing combination are provided, the method can manufacture the mouth protector capable of alleviation of nose and surrounding of the nose and of reduction of the wearer's load. The invention matching-contacts a deformable frame component acquired by immersing in the hot water to the face of the mouth manufacturing object to surround the covered region of the object, after that, a filter component (20) is mounted at the frame component (10b) fixed by cooling, so as to manufacture the mouth protector (1). Therefore even in case that a headband set tensions the whole body of the mouth protector strongly, the frame component can absorb suction totally. Accordingly, severe deformation of the frame component (10b) at the parts corresponding to the nose and around the nose can be prevented, and the pressure to the nose and the surrounding of the nose can be lessened, the wearer is also reduced the load.
