As shown in Figures 2A and 2B, a method for manufacturing a mask device 90A is disclosed, which includes a mask body 95 and two cloth surfaces. Ear straps 97A, 97B, the mask body 95 can be made of a combination of multi-layer non-woven fabrics, and is folded with several folded layers 99. The folded layers 99 can be easily unfolded during use to fully cover the user's mouth and nose. The mask body 95 is provided with a plastically deformable metal pressure strip 98 at the inner upper edge, so that it can be pressed and attached to the user's face shape; Both ends are respectively fixed to the side area of the mask body 95 95A, 95B upper and lower ends. The manufacturing method of the conventional mask device 90A is to first complete the related production of the mask body 95 connected by long strips, including folding, pressing, forming a folded layer 99 of a multi-layer non-woven fabric combination, and setting a plurality of separating metal strips 98.
