  • Patent number: 11707706
    Abstract: The present disclosure relates generally to air filtration devices. More specifically, but not exclusively, the present disclosure relates to an air filtration device comprised of a copper (or copper alloy) medium to inactivate airborne pathogens (e.g., viruses, bacteria, coronaviruses, COVID-19, etc.) and mitigate harmful exposure to said pathogens. The copper medium is a porous mesh (i.e., copper wool) that is positioned within or on a structure to provide support. The air filtration device may be positioned in an HVAC system such that an air stream flows through the copper medium to inactivate airborne pathogens, such as viruses, in the air stream. The air filtration device may be used in combination with, or in addition to, existing HVAC system conventional air filters (e.g., HEPA filters). The air filtration device includes a copper medium positioned on a face mask to inactivate airborne pathogens during respiratory processes.

    Abstract: Disclosed is an air filtration mask formed from individual connectable components namely a base member, a filter holder member, a filter member, and an optional decorative mask cover member. The base member employs studs which allow the filter holding member to securely attach to the base member by means of holes in latches located around the rim of the filter holder member. A replaceable filter member attaches to the filter holder member snapping into the studs located on the inside of the filter holder. A fashion mask cover member can be attached to the front of the filter holder to enhance the appearance. A fashion scarf or bandana can be further attached to the base of the mask so that the mask assembly can stay completely hidden while worn.
