New description: [New technical field] A three-dimensional mask, especially a folding three-dimensional mask. [Prior Art] Micro-filter masks have been widely used in various applications to protect the health of the user's respiratory system. Generally, micro-filter masks are mainly available in two types: cup type or folding type, and the folding type has the advantage of being convenient for storage. In the user's pocket, the mask needs to be unfolded until it is used. In addition to the convenience of carrying, the edge of the folding mask is not like the shape of the cup mask, so it can fit the user's face when worn. Provides a good degree of fit. With the improvement of the filter cloth technology, the filter effect of the mask can now achieve the ultimate protective effect. According to the N丨〇SH certification standard of the United States, the filtration effect grades are 95%, 99% and 99.97%, respectively.
