A surgical mask having partitions that isolate the respiration from the nose and mouth of a wearer into two separate compartments or volumes.

A facemask assembly has a three dimensional shape to fit a user's face while covering a user's mouth and nose and providing a space in front of the user's mouth and nostrils. The facemask assembly includes an outer shell layer and an inner lining layer connected to provide a facemask panel having the three-dimensional shape and an interior space to retain a filter. A face stiffener extends through the interior space along a mid-region and curved away from the user's mouth to assist in stiffening the facemask panel and in keeping the three-dimensional facemask shape spaced from the user's mouth. Magnets can also be used to aid is retaining the facemask assembly as a shaped unit. An adjustment tab can aid in adjusting the facemask assembly on the face. The facemask assembly can be pulled down when safe while retaining it three-dimensional shape.

An object is to provide a mask frame capable of allowing a mouth to be less likely to be constrained by a frame at the time of talking while preventing a mask from coming into contact with a part around the mouth and a nose and capable of fitting to a face regardless of the face shape of each person and a method of using the mask frame. A mask frame (1) includes: two vertical materials (2) that are disposed such that a longitudinal direction of the vertical materials is aligned along an up-down direction when the mask frame is worn on a face, and come into contact with left and right cheeks, respectively; a plurality of horizontal materials (3) that are provided between the vertical materials (2) such that a longitudinal direction of the horizontal materials is aligned along a horizontal direction and are disposed at positions away from the face when the mask frame is worn on the face; and a reinforcing material (4) that is disposed such that a longitudinal direction of the reinforcing material is aligned along the up-down direction when the mask frame is worn on the face and is connected to each of the plurality of horizontal materials (3), in which the vertical materials (2), the horizontal materials (3), and the reinforcing material (4) are placeable further inward than an outer peripheral edge of a filter of a mask, and all the plurality of horizontal materials (3) are away from the face such that no part of each horizontal material (3) comes into contact with the face when the mask frame is worn on the face.

A personal respiratory protection device comprising an upper panel (18), a central panel (16), and a lower panel (20), the central panel (16) being separated from each of the upper and lower panels (18) by a first and second fold (36), seam, weld (76) or bond, respectively, such that device is capable of being folded flat for storage along the first and second fold (36), seam, weld (76) or bond and opened to form a cup-shaped air chamber over the nose and mouth of the wearer when in use, wherein the lower panel (20) has a graspable tab (32) attached to an interior portion of an external surface of the lower panel (20), the tab (32) being graspable in use to open the device.

A respirator (10) and a process of making the respirator (10) are disclosed. The respirator (10) can include a mask body (12) including right and left portions (16, 18) on each side of a centerline (14), where the right and left portions (16, 18) are bounded by a perimeter (24) of the mask body (12). The mask body (12) can also include a right tab (30) that extends from a right side perimeter segment (26) of the perimeter (24) of the mask body (12) adjacent the right portion (16), and a left tab (40) that extends from a left side perimeter segment (28) of the perimeter (24) of the mask body (12) adjacent the left portion (18); a right earloop (60) attached to the right tab (30) at first and second right attachment locations (50, 54); a left earloop (62) attached to the left tab (40) at first and second left attachment locations (52, 56); and a nose clip (92) disposed adjacent an upper perimeter segment (22) of the perimeter (24) of the mask body (12).

A facemask includes a breathing area for filtering air; and a compressible gasket formed on a periphery of the breathing area to abut on a user's face; wherein the compressible gasket has a three-dimensional and airtight configuration. A facemask includes a breathing area for filtering air; and a compressible gasket formed on a periphery of the breathing area to abut on a user's face; wherein the compressible gasket comprises a nonwoven first layer to biased against the wearer's face so as to support the three dimensional configuration of the compressible gasket, and a protection thin layer made of airtight material attached on an inner surface of the nonwoven first layer.

Filter media including a waved filtration layer are described herein. The filtration layer may be held in a waved configuration by a support layer. In some cases, the filtration layer may have a combination of characteristics (e.g., mean flow pore size, basis weight, amongst others) that can lead to enhanced filtration performance (e.g., reduced air permeability decrease), in particular, in high humidity environments. The filter media may be used to form a variety of filter elements for use in various applications. In some embodiments, at least a surface of the filtration layer is hydrophilic.

A kit includes at least one facemask configured to cover a respective user's mouth and nose. The facemask contains at least one layer impregnated with a first chemical. When the facemask covers the respective user's mouth and nose, airborne particles of the first chemical are released from the at least one layer through the user's breathing. A sensor is configured to measure airborne concentration of the first chemical. A processing circuitry is configured to receive outputs of the sensor, to calculate a change in airborne concentration of the first chemical, and to issue a notification when the airborne concentration of the first chemical increases at above a predetermined rate.

One or more embodiments of a respirator and a method of making the respirator are disclosed. The respirator can include a harness (60) including first and second straps (62, 64); a mask body (12) including right and left portions (16, 18) on each side of a centerline (24), where the right and left portions (16, 18) are bounded by a perimeter (24) of the mask body (12); a right tab (30) that extends from a right side perimeter segment (26) of the perimeter (24) of the mask body (12) adjacent the right portion (16); and a left tab (40) that extends from a left side perimeter segment (28) of the perimeter of the mask body (12) adjacent the left portion (18). The first strap (62) of the harness (60) is attached to the right and left tabs (30, 40) at first right and left attachment locations (50, 52), and the second strap (64) is attached to the right and left tabs (30, 40) at second right and left attachment locations (54, 56).

A smart mask is proposed, which combines a virus protection function with a sweat-absorbing and quick-drying function, an antibacterial and deodorizing function, and a skin care function. The smart mask includes an outer covering fabric of a three-ply fabric structure including an outside fabric, an inside fabric, and an intermediate fabric intersecting and knitting between the outside fabric and the inside fabric; and an inner covering fabric obtained by coating and drying a composition on a first surface thereof, the composition containing a water-repellent agent for fiber, a functional microcapsule obtained by micro-encapsulating functional oil that has antibacterial and deodorizing effects or skin care effects, and an aqueous binder for processing a fabric, the inner covering fabric being joined to the outer covering fabric by attaching a second surface of the inner covering fabric to a surface of the inside fabric.
