An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a sterilization light assembly. The housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air therefrom. The sterilization light assembly may be disposed within the housing to transmit an ultraviolet light emission thereto. The sterilization light assembly may include a support board, an ultraviolet C (UVC) light source, and a lens casing. The UVC light source may be mounted to the support board and configured to emit radiation between 200 to 280 nanometers. The lens casing may be disposed over the support board and seal the UVC light source to prevent moisture from contacting the UVC light source.

A ventilation system is provided, the ventilation system comprising at least one air flow generating device, the at least one air flow generating device having a calibrated speed to produce a downward air flow capable of forcing a cloud of infectious bacterial, viral or pathogen particles or droplets out of an ingestion zone of a mouth, a nose and eyes of an individual, at least one ultraviolet C light lamp positioned proximate at least one wall of an area in a pathway of an infected air flow, the infected air flow containing the cloud of infectious bacterial, viral or pathogen particles or droplets, an ultraviolet C radiation field created by the at least one ultraviolet C light lamp, the ultraviolet C radiation field extending throughout the area from the at least one wall near a ceiling of the area and the infected air flow containing the cloud of infectious bacterial, viral or pathogen particles or droplets passing through the ultraviolet C radiation field, wherein the at least one air flow generating device is positioned to enable an upward air flow return to the at least one air flow generating device to force the infected air flow and the cloud of infectious bacterial, viral or pathogen particles or droplets out of an area and through the ultraviolet C radiation field to eradicate the infectious bacteria, virus and pathogens from the infected air flow, and wherein a fresh air flow free of infectious bacteria, viruses and pathogens is reintroduced back into the area by the downward air flow of the at least one air flow generating device.

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.

A portable air filtration apparatus capable of rapid and efficient room air turnover and recirculation of filtered and decontaminated air with eradication of both microorganisms and biological agents. The invention relates to a compact device that can be used in ultra-clean air purification using a multi stage electrostatic precipitation and air filtration with disinfection and eradication of both microorganisms and biological agents by the application of ultraviolet light radiation. It can be used in any application where space, lower cost or ultra-fine particulate filtering is needed; such as in clean rooms and surgical suites. The device is extremely efficient for purifying contaminated air from entrained dust and organic substances without using chemicals and physical filters, and it is hygienic and fireproof. The device including its multi stage electrostatic precipitator with the filter, connecting, releasing tubes and the fan is easy to clean and can be portable.
