Further, it is described it is vertically folded center line is erected as the symmetrical distribution of symmetry axis using mask, it is vertical on the left of symmetry axis Arrange between folding and right side are vertically folded in "eight" shape.

Further, it is described it is vertically folded center line is erected as the symmetrical distribution of symmetry axis using mask, adjacent vertically folded Arrange in just " eight " word or inverted "eight" shape.

Further, filter is in the form of sheets after the folding.

Further, filter is in bowl-shape after the folding.

Further, the filter is equipped with one-way breather valve.

Further, it is connected with drawstring between the folding.

Further, the filter edge is surrounded by edge sealing in vertically folded bonding place.

Further, it is described vertically folded for "the" shape folding.

The present invention is provided with folding line in vertical vertically folded on filter, bowl formula structure using when fold and stretch out, Intermediate lateral length is more than upper and lower edge lateral length, can further expand it is bowl-shape cover forwards or both sides space, reduced Contact of the filter disc with cheek, makes filter maintain higher effective filtration area, folds the presence of fold and also further increases The effective filtration area of filter, reduces the pressure difference inside and outside filter, causes airflow smooth to reduce the sensation felt suffocated, pressure The reduction of difference lowers the air-flow velocity at filter micropore, can effectively prevent the excessive suction microparticle of air-flow velocity, effective mistake The increase of filtering surface product also lays the foundation to reduce filter hole raising filter effect；Fold when chip mask is worn or so and to draw Expansion, same intermediate lateral length are more than upper and lower edge lateral length, and upper and lower in mask can to form one steeper to evagination Go out space, the protrusion spatial shape is stablized under fixed band drawing, will not oppress mouth and nose, and vibrations deform small, filter and face Contact area is small, and effective filtration area is big, airflow smooth, and air flow rate is balanced everywhere for filter, filter filtering efficiency everywhere Performance can be balanced, a steeper outstanding space is formed with filter upper edge under pulling fixed, the space Being formed can also promote the nose two of filter top edge laterally facial close, and wing of nose position is closer to wing of nose nest, raising leakproof Gas performance, improves integral filter effect；Also the prominent nose of face and lower jaw are respectively contained in upper and lower outstanding space, There is no tight constriction, wear more comfortable.
