A personal respiratory protection device comprising a main body (12) carrying an exhalation valve (28), the valve (28) having a grip region (29) which is grippable in use by the user, the grip region (29) being configured to indicate to the user that the valve (28) is to be gripped during opening, donning and doffing of the device.

A filtration component for a respiratory protective device is provided. For example, the filtration component includes a filter body and a dispersing element container. In some examples, the dispersing element container includes a tube element fastened to a cover element.

An anti-fogging facemask for preventing fogging of the wearer's glasses or goggles is described herein. The anti-fogging facemask includes an outer facemask and an inner facemask. The inner facemask is attached to the outer facemask. The inner facemask provides a barrier to prevent exhaled air from traveling through the upper end of the facemask. The inner facemask directs exhaled air downwards. The outer facemask forms a seal at an upper portion of the wearer's nose. The facemask may be configured to serve as a CO2 concentrating mask for temporary relief of allergic rhinitis symptoms.

A method for providing a bio-active layer on a surface, includes the steps of: a) ionizing a plasma gas at low temperature of 150° C. or lower, and at about atmospheric pressure, thereby creating a plasma; b) introducing a precursor into said plasma; c) exposing the surface to said plasma comprising said precursor, thereby forming a coating onto the surface. The precursors include a biological pathogen transfer inhibiting compound.

Protective coverings having metal nanoparticle agglomerates adhered thereto may be applied to a surface subject to infection. The protective coverings may comprise a base substrate, and metal nanoparticle agglomerates thereof adhered to the base substrate. The base substrate may be configured for attachment to the surface subject to infection. The surface subject to infection may be a mask or facial covering in a particular example. The base substrate may be conformable to the surface subject to infection and optionally include mechanical connectors and/or a contact adhesive upon at least one side thereof to promote surface attachment. The protective coverings may be applied to a contaminated touch surface as a temporary protective layer until disinfection has taken place. Alternately, the protective coverings may be used in routine infection control procedures. The protective coverings may be formed by applying a spray formulation comprising metal nanoparticle agglomerates upon a suitable base substrate.

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.

One or more embodiments of the present disclosure includes antiviral masks with at least one metallic layer. In one or more embodiments, the at least one metallic layer can be a copper based metallic layer and can be shaped as a facial mask that covers the exposed orifices of a user's face, including the nose and mouth, and can be used independently of other layers and/or other masks.

A mouth includes four pieces of plastic foil or layers placed against each other, in particular a first external layer, a first internal layer, a second internal layer and a second external layer, these layers having at least partially corresponding peripheral edges, and wherein the four pieces of plastic foil or layers are connected along a first fraction of their corresponding peripheral edges by a quadruple welded joint connecting the four layers.

A disposable mask or optically transparent mask comprising a mask body is provided. The disposable mask includes a periphery, and straps attached to the mask body proximate the periphery for releasably retaining the mask on a user's face, the mask body including: an inner layer, which is a polymeric plastic material with a plurality of passageways therethrough, and which has an inner surface and an outer surface; and a porous glass filter which is functionalized with a visible light photocatalyst and abuts the outer surface of the inner layer. Apparel comprising fiberglass which is functionalized with a visible light photocatalyst is also provided.
