A respiration filtering face mask that can be washed and sterilized by common means and reused repeatedly comprised of a filtering component that is a laminate of at least one layer of particle filtering material and at least one layer of a microbe killing metallic woven cloth laminated together by adhesive or fusible material in a manner that allows low resistance to air flow, cut to a shape that is folded into a modified cone, a padding filled gasket that is continuously sealed to the outer edge of the filter cone, harness straps that are elastic and user adjustable for length and tension, and an attached shield to prevent fogging of eye ware. A method for making said anti-microbial filter and respiration filtering face mask.

Aspects of various embodiments herein may be implemented as follows. An apparatus has a material shell that conforms to a user's face, and a securing portion connected to the shell that may operate to secure a filter to the user's face with the filter covering the user's nose and mouth. A securing force may be applied to the filter via the first material portion in a direction toward the user's face, thereby sealing the filter around the user's nose and mouth. Various implementations involve elastic and other material that facilitate sealing of the filter around the user's nose and mouth.

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.

The present invention relates to a subject specimen tool for virus testing and, more specifically, to a subject specimen tool for virus testing, which enables an examiner to collect a specimen of a subject by using a specimen collection swab, while being worn by the subject, and is kept airtight during specimen collection, so that a contaminant in a mask does not leak outside of the mask, and thus, contamination around testing and infection of the examiner can be prevented. To this end, provided is a subject specimen tool for virus testing, comprising: a mask for shielding the face or a portion thereof of a subject; a specimen collection swab which is inserted into the mouth or nose of the subject wearing the mask, to collect a specimen; a swab insertion/withdrawal hole part formed in the mask and having a path with a diameter sufficient for the specimen collection swab to be inserted thereinto and withdrawn therefrom; and a detachable cap configured to be detachable from the swab insertion/withdrawal hole part and having an opening means which is open to guide the specimen collection swab to the path of the swab insertion/withdrawal hole part, wherein the opening means is open only in one direction toward the swab insertion/withdrawal hole part.

The disclosed anti-contagion facemask embodiments are a family of transparent facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used, facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding the wearer's mouth and face with opaque filter material. Accordingly, some embodiments described herein present a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth by providing a filtration system along or near the periphery of the facemask.

An off-the-face mask including a mask body comprising one or more layers and having a surface area defined by a plurality of zones, wherein at least two of the plurality of zones have different stiffness levels; and one or more straps coupled to the mask body and configured to hold the mask on a wearer of the mask.

Methods, apparatuses, and systems associated with personal protective equipment are provided. An example mask may include an exterior layer, one or more mask straps coupled to the exterior layer, and a filter layer. An example method for manufacturing a protective garment may include providing a front segment, providing a back segment, and connecting the front segment and the back segment by at least forming a front raglan seam.

A process for the production of manufactured articles in composite material comprises at least one supply phase of a plurality of layers and at least one coupling phase of the layers. The coupling phase comprises at least one step of arrangement of the layers overlapped onto each other to create at least one stratified body. The coupling phase comprises at least one step of positioning the stratified body inside a mould. The coupling phase comprises at least one firing step of the layers positioned inside the mould. The supply phase comprises at least one supply step of at least one basic layer and at least one supply step of at least one reinforcement layer.

Embodiments relate generally to methods and systems for detecting and indicating end-of-service-life in disposable filtration masks. Applicant has proposed incorporating end-of-service-life indicators comprising color changing chemicals into the mask. The indicating chemicals may be incorporated into the nonwoven fabric material of the mask, or may be attached to the nonwoven material of the mask, such as by dipping, spraying, or adhering. The color change of the indicating chemicals may indicate to a user that the use life of the mask has been depleted.
