A support frame for being used with a face mask includes a resilient transverse rod and a longitudinal extension longitudinally extending from a middle portion of the transverse rod and having a strip-shaped or belt-shaped pattern including two ends connected with the transverse rod in a way that a part of the transverse rod and the longitudinal extension combinedly define a hollow portion. Therefore, when a user wears the mask quipped with the support frame, the longitudinal extension and the transverse rod expand the mask outwardly, such that the mask won't be completely attached on the mouth and nose of the user, thereby effectively enhancing comfort of the user wearing the mask. Further, the support frame can be applied to any masks with a fold portion and can be reused. The support frame has a light and simplified structure having a small size to be conveniently stored.

The present invention relates to a face mask that protects the wearer from pathogens while enabling the wearer to be heard clearly, even at larger distances. The face mask can be a multilayered mask having a vent for expelling exhaled air and a combination of a microphone and a speaker for capturing and amplifying the sound of the wearer. Further, the face mask includes a temperature sensor for sensing the real-time temperature of the wearer, and an oxygen sensor for monitoring the blood oxygen level of the wearer. The temperature and the oxygen level can be transmitted to a paired software application installed in an electronic device for visualization and processing. The face mask amplifies the voice in situations where it is difficult to project same through the mask.

A face mask that uses a super sticky substance that is sprayed between the 3 material layers of the mask and in its exhaust valve filter to trap and hold particles or microbes when breathing in and out and replicates the body's own sinus defenses in filtering air via cilia hairs and sticky mucus.

In some embodiments, a facemask assembly can include a strap system, a facial skirt, a filter assembly, a filter material, mounting bracket, front section, a tilt mechanism, and/or a seal-tester. In some embodiments, the facial skirt has at least two seal-layers. In some embodiments, the strap system has a crown section.

An eyeglasses-like frame may include a central section that horizontally traverses a wearer's face. The central section may include a first cheek portion sized and configured to be disposed at least proximate a cheek of the wearer, and a second cheek portion sized and configured to be disposed at least proximate a cheek of the wearer. A bridge portion may be generally horizontally disposed between the first cheek portion and the second cheek portion. The first cheek portion, the second cheek portion, and the bridge portion may be disposed below a lower portion of the wearer's eyes. The eyeglasses-like frame may include a left temple section connected to the central section via a first hinge and a right temple section connected to the central section by a second hinge. A mask may be connected to the frame and the mask may be adjustable to tighten around the wearer's face.

A filtering facepiece respirator decontamination device includes an enclosure defining a UV irradiation chamber, at least one UV lamp positioned in the irradiation chamber, a moveable drawer comprising a platform for positioning a respirator, wherein the moveable drawer can move to a closed position in the respirator positioned on the platform is located in the irradiation chamber, a switch for detecting that the drawer is in the closed position, and a controller for activating the at least one UV lamp based on the switch detecting that the drawer is in the closed position.

Disclosed are a non-woven fabric composite and an article including the same. The disclosed non-woven fabric composite includes an at least partially electrostatically treated meltblown non-woven layer and a spunbond non-woven layer disposed on one or both sides thereof, pressure loss is less than 5.0 mmH.sub.2O, and a size of the pilling mass after the Martindale abrasion test is less than 5 mm.

Provided are a method of producing ear loop members for masks and a device for producing ear loop members for masks with which it is possible to inhibit a reduction in the production efficiency of the masks. The method of producing ear loop members (4) for masks includes a conveyance step (S2), a tension adjustment step (S3), and a forming step (S4). In the conveyance step (S2), a sheet (U1) having high stretchability in a high-stretch direction (DH) is conveyed in a conveyance direction (C10) running along the high-stretch direction (DH) while tension is applied in the high-stretch direction (DH) to the sheet (U1). In the tension adjustment step (S3), the tension in the conveyed sheet (U1) is adjusted. In the forming step (S4), ear loop members (4) are formed by cutting the sheet (U1) after the tension adjustment.

A mask assembly comprising a face covering portion, a pocket connected to the face portion and positioned to cover a wearer’s nose and mouth, where in a filter is removably inserted into the pocket, the filter comprising a porous hydrophobic and lipophobic layer, a diamond - like carbon coated copper layer, and a non- woven fabric layer. A filter containing at least one porous hydrophobic and lipophobic layer, at least one diamond like carbon coated copper layer interposed between two non-woven fabric layers, and at least one additional non- woven fabric layer. A filter comprising at least one porous hydrophobic and lipophobic layer, at least one diamond - like carbon coated copper layer, and at least one non - woven fabric layer, the at least diamond-like carbon coated layer is between the at least one porous hydrophobic and lipophobic layer and at least one non - woven fabric layer.

A composite multi-layer textile, comprising at least one nanofibre layer with nanofibres with diameters below 100 nm and one support layer with microfibres with diameters below three microns, wherein the layers were produced by electrospinning. The multi-layer textile shows a general transmittance at #=550 nm greater than 60%, which shows improved properties concerning transparency, breathability and robustness. This is achieved in that the at least one nanofibre layer and the support layer are fused, forming solid domains in the multi-layer textile, at closed areas of a pattern used in the production process, wherein the solid domains are separated from each other or connected, showing defined shapes, with regular or irregular spatial distribution, while the fibre morphology of nanofibres of the nanofibre layer and microfibres of support layer is preserved on top of the open areas beside the solid domains, attaining a general transmittance greater than that given by the sum of the individual layers.
