A face mask has a centrifugal fan assembly, with a radial outlet outside the mask cavity. A flow adjusting element is added to prevent outlet flow from the fan assembly traveling along the outside of the mask and reaching the user, for example at the neck.

A mask with a seal along an upper portion of a mask to divert air flow along a lateral axis of the mask.

A mask protecting the user and attached or sown to utility and or wear onto the body to prevent general contamination of the user, especially dust, flu, biological, or chemical, control or terminate person to person contamination, stop continue body or utility recontamination and spreading of dust, biological or chemical agents into the body, or utility. The new mask may include a medical or anti bacteria disinfectants, maybe powder, liquid, capsule or other types to control and kill germs, further the new mask have a holder, with plurality of holes, and connectors and or interconnector holding the masks to the body or utilities, like professional garment or uniforms, neck tires, T shirt, shirts, seat, car seat, bed, ear, chin, head, hand, while covering the users, faces, or half faces, particularly, the nose, eyes and the mouth from harm.

The present disclosure provides a filtration media for filtering one or more airborne particles. The filtration media may comprise a membrane comprising one or more polymeric layers to filter the airborne particles. The filtration media may have high filtration efficiency and high breathability. Additionally, the present disclosure provides devices (e.g., face masks) comprising the filtration media which may be used to filter airborne particles (e.g., bacteria, viruses) and to protect the wearer (e.g., from infection).

A reusable multipurpose face mask is provided, particularly a face mask with a transparent shell, a housing having two air passageways with chambers that are covered by replaceable, disposable, and/or reusable membrane filters coupled to two openings in the transparent shell that are positioned on the sides of the face mask, and a third multipurpose opening that can be used for a housing having a mini rechargeable voice amplifier with built in microphone and speaker. An adjustable reusable hook and loop Velcro fastener elastic strap is attached to the transparent shell and adapted to be adjusted using the hook and loop and then removed and replaced by stretching the elastic strap while removing without having to adjust the Velcro strap each time. A system is also provided comprising the face mask and a germicidal UV light sterilization box for housing and recharging the mask when not in use.

An article of manufacture providing a face attachment devices for securing a face covering to a face according to the present invention have chin attachment device, a nose bridge attachment device, and a pair of cheek attachment devices. The chin attachment device has a pair of strips of hydrogel self-adhesive material stacked on top of each other for use about a chin. Each of the cheek attachment device having a first top and a first bottom strip of hydrogel self-adhesive material stacked on top of each other for use on a first cheek, the first top strip of hydrogel self-adhesive material being placed on top of a rectangular cheek inserted structure between the first top and first bottom strip of hydrogel self-adhesive material. The nose bridge attachment device having a nose bridge top and a nose bridge bottom strip of hydrogel self-adhesive material stacked on top of each other for use on a nose bridge, the nose bridge top strip of hydrogel self-adhesive material being placed on top of a pair of triangular-shaped structure between the nose bridge top and nose bridge bottom strip of hydrogel self-adhesive material.

Embodiments disclosed herein include a stitched filtering fabric including a barrier layer configured to inhibit air flow through the filtering fabric, a yarn stitched through and forming a plurality of stitch holes in the barrier layer, and a first yarn layer comprising interlocking loops of the yarn. The barrier layer is configured to direct air flow through the yarn within the stitched holes.

An antimicrobial air treatment device and a method of its construction. The antimicrobial air treatment device comprises an antimicrobial metal nanoparticle mesh comprising a steel support mesh and a layer of copper nanoparticles disposed on the steel support mesh. The antimicrobial air treatment device may be in the form of a facemask or a component of a moving air filtration system such as an HVAC system, an automobile cabin air filtration system, and an air purifier. The antimicrobial air treatment device may contain one or more filtration layers of filtration medium. The method of constructing the antimicrobial air treatment device involves the preparation of the antimicrobial metal nanoparticle mesh by an electrodeposition technique.

The use of Manuka Honey in the production of a medicament for treating a virus by applying the honey, via the medicament, to the periphery of tissue on which the virus is present. Further, The use of one or more of methylglyoxal; 3-phenyllactic acid; p-coumaric acid; quercetin; pinocembrin; pinobanksin; hesperidin; galangin; kaempferol; chrysin; and luteolin in the preparation of an antiviral medicament for administering to a patient to treat, or prevent, infection by the virus. Further, a respiratory mask comprising a barrier permeable to air, the barrier having sufficient Manuka Honey for substantially disinfecting a vims in air when breathed in or otherwise passed through the barrier while the mask is worn.

A filter assembly comprises an air filter medium and a prefilter medium. The prefilter medium comprises a second nonwoven fibrous web comprising poly(4-methylpentene) and an electrostatic charging additive and has a second electret charge. The filter assembly is configured such that air passing through the prefilter is directed through the air filter medium. A respirator includes the filter assembly. A prefilter assembly comprises a third nonwoven fibrous web retained by a prefilter frame. The third nonwoven fibrous web comprises: core-sheath fiber comprising a fiber core having a poly(4-methylpentene) sheath layer disposed thereon; and an electrostatic charging additive, wherein the electrostatic charging additive is contained in at least one of the fiber core or the sheath layer. The third nonwoven fibrous web has a third electret charge.
