A respirator includes a mask shell, a face flange attached to a rear edge of the mask shell, a filter cover removably attachable to the mask shell, a filtration media removably secured between the filter cover and the mask shell, and scannable identification device.

A facepiece comprising a main body having a geometry configured to fit on a human face and cover the human's mouth and nose is provided. The main body defines an interior cavity between the main body and the human's face. The facepiece also includes one or more straps extending from the main body and configured to extend around the ears or head of a human such that the main body is held on the human's face. The main body includes a filter defining a plurality of airflow torture paths extending therethrough between the interior cavity and an external environment. The filter includes three or more layers of airflow path defining features, each airflow path defining feature providing a passageway for air to pass therethrough. The path defining features in adjacent layers are fluidly coupled but offset to form the airflow torture paths.

A medical grade reusable and washable fabric/cloth face mask comprising a plurality of filtration layers located between a first and last layer of top quality cotton, polyester or other suitable fabric. In at least one embodiment, the present invention consists of an N95 grade filter. In other embodiments, the face mask consists of a plurality of non woven polypropylene melt blown material. The invention provides a high level of filtration and can be washed and reused.

A method for producing an improved mask or device for killing or deactivating pathogens, such as viruses. A mask or device produced in accordance with the method for producing. A method for killing, or making inviable, viruses, such as airborne viruses. A pathogen-deactivating assembly having two zones of hydrophilic particulate matter for deactivating a pathogenic aerosol. The two hydrophilic particulate matter zones are separated by a hydrophobic fibrous partition.

A facemask assembly and method of manufacturing the same includes a thermo-polymer strap along the nose and upper cheek areas that can be custom conformed by the wearer to create an effective seal in both those areas of the face plus can be flared inward/outward to enhance the seal below the chin. In some embodiments a snap-together, two-part framework is employed to increase the breathable filter surface area and bring such near the mouth and nose. In some embodiments, the facemask has a front clip component that enables inserting elastic tubing/strap adjustably below the nose or looped back and then also inserted below the mouth to create ear loops. In addition, the external front clip—pressing between the filter and the interior back frame—allows for the vertical adjustment of the strap/tubing to customize/optimize the facial seal.

In addition, the front clip can be externally disconnected and internally inserted to create a strap holding method or a strap clip can be inserted to also hold within the facemask the straps that would otherwise be loose.

A facial covering assembly comprises an inner frame comprising at least one aperture to allow air flow through the inner frame and an outer frame configured to couple to the inner frame. The outer frame comprises at least one aperture to allow air flow through the outer frame. The facial covering assembly further comprises a cushioning element configured to couple to the inner frame, the cushioning element configured to establish a seal around at least a portion of a user's face.

The present disclosure delineates both active as well as passive respiratory filtration systems. The respiratory filtration systems are configured to be worn by a user, providing the user protection from the ambient environment, possibly containing microorganisms, pathogens, particulate matter, and the like. Some embodiments are also designed to protect observers, by filtering user exhalation air released into the environment. Nontransparent members of the system are configured to be located over impassive features of the user's face, such as the cheeks or chin areas. The disclosed respiratory filtration system(s) includes one or more hygienic materials. The hygienic materials are carefully selected and disposed at predetermined locations within the respiratory filtration system, so to optimize user to the observer(s) communications. Optimized communications include the transmission of distortion-free speech and/or unobstructed view of the user's oronasal area—via an expression window(s).

A respiratory face mask having a breathing cartridge therein which face mask breathing cartridge can both filter the breathing air while passing the breathing air through a voltage being generated by the cartridge. The cartridge generates a galvanic cell using spaced apart dissimilar metal particles when immersed in an electrolyte being held by an adjacent hydration layer of liquid retaining foamed polymer having breathing passageways therethrough.

A handheld mask assembly for protecting a user's face without a strap. The handheld mask assembly comprises a face mask component, an attachment component, and a rod. The attachment component is joined to or otherwise integrated into a corner of the facemask component and is configured to engage one end of the rod. One end of the rod is insertable into the attachment component when the user desired to hold the face mask component over their nose and mouth. The rod is removable when not needed. The handheld mask assembly may further comprise a strap for engaging the face mask component to secure the face mask component around the user's head for longer periods of time when the rod is removed.

An adjustable mouth shield device provides an adjustably fitted mouth shield with adjustable headband for secure fit. An adjustable headband is fastened to a padded earpiece. A straight first extension from the earpiece is angled downwardly and forwardly to terminate in a swivel joint providing almost 360 degrees of swivel. A second extension is arced both downwardly and forwardly. A mouthpiece is fitted to an adjustable spring mount for horizontal pivot of the mouthpiece. The mouthpiece may, by virtue of the swivel joint and the spring mount, be moved completely away from a user's mouth and, in turn, pivoted and swiveled to be directly in front of the user's mouth. A filter is releasably attachable to the mouthpiece to shield a user's breath from objects, foods and other materials.
