an outer cover made of ultra fine fibers and formed by hot-pressing, the outer cover having a plurality of through holes for ventilation and having a predetermined three-dimensional shape to fit facial features of a user;

a filter configured to filter air and disposed at a side of the outer cover adjacent to the user; and

two sealing pads, each attached to a side of the filter adjacent to the user and configured to contact skins at two sides of a nose bridge of the user to seal gaps between the filter and the two sides of the nose bridge of the user,

wherein each sealing pad comprises:

a supporting sheet body formed as a smooth-curved body projecting in a direction away from the filter; and a supporting rib sandwiched between the filter and the supporting sheet body, and arranged substantially in middle of the supporting sheet body along a left and right direction, for supporting the supporting sheet body,

wherein the supporting sheet body comprises a first edge extending along a straight line and connected to the filter, and the supporting sheet body is configured to be flipped up and down along the first edge;

the supporting rib comprises a front edge and a rear edge connected with a front surface of the supporting sheet body, the front edge being configured to swing leftwards or rightwards around a joint of the rear edge of the supporting rib and the front surface of the supporting sheet body to reduce a gap between the supporting sheet body and the filter due to restriction from a rear surface of the filter when the supporting sheet body is pressed forwards to push the supporting rib to move forwards; and

the first edge of the supporting sheet body extends n a direction substantially perpendicular to an extending direction of the rear edge of the supporting rib.

2. The mask according to claim 1 , wherein a first number of the plurality of through holes are opposed to mouth and nose regions of the user, and a second number of the plurality of through holes are opposed to a cheek of the user, wherein a diameter of each of the first number of the plurality of through holes opposite to the mouth and nose regions of the user is larger than a diameter of each of the second number of the plurality of through holes opposite to the cheek of the user.

3. The mask according to claim 1 , wherein the outer cover comprises:

a first outer cover portion, opposite to at least the mouth and nose regions of the user and configured to be spaced apart from the mouth and nose regions of the user; and

5. The mask according to claim 3 , wherein the outer cover comprises two wings, and the two wings are connected to both sides of the second outer cover portion and extend towards ear gates on both sides of the user, respectively.

6. The mask according to claim 5 , wherein a distance between an upper edge and a lower edge of each wing is decreased gradually towards the ear gate at a corresponding side.

7. The mask according to claim 5 , further comprising:

two ear-hanging assemblies detachably connected with two sides of the outer cover, respectively.

8. The mask according to claim 7 , wherein each ear-hanging assembly comprises:

a connecting member detachably connected with the outer cover; and

an ear-hanging strap connected to the connecting member and configured to hang on the ear of the user.

9. The mask according to claim 8 , wherein the connecting member comprises:

a first sheet having a positioning protrusion; and

a second sheet having a positioning hole operable with the positioning protrusion that passes through the outer cover, wherein the first sheet and the second sheet are connected with each other and foldable with respect to each other along a joint therebetween, and the wing is sandwiched between the first sheet and the second sheet.

10. The mask according to claim 8 , wherein both ends in a longitudinal direction of the ear-hanging strap are detachably connected with the connecting member.

11. The mask according to claim 8 , wherein both ends in a longitudinal direction of the ear-hanging strap are pivotably connected with the connecting member.

12. The mask according to claim 1 , wherein an overall lower edge of the outer cover is formed in a substantial V shape.

13. The mask according to claim 1 , wherein an outer contour of the filter is similar to an outer contour of the outer cover.

14. The mask according to claim 13 , wherein a distance between an upper edge of the filter and an upper edge of the outer cover ranges from 1 mm to 3 mm, and a distance between a lower edge of the filter and a lower edge of the outer cover ranges from 1 mm to 3 mm.

15. The mask according to claim 1 , wherein the filter is made of multiple-layer filtering materials and formed by hot-melting, and has hot-melt marks opposite to mouth and nose regions of the user.

16. The mask according to claim 15 , wherein the hot-melt marks comprise a transverse hot-melt mark extending in a left-and-right direction, and/or a longitudinal hot-melt mark extending in an up-and-down direction.

17. The mask according to claim 1 , wherein the filter and the outer cover are detachably connected.
