  • the present invention relates to a device for blocking airborne transmission of infectious diseases. More specifically, not only is the virus discharged from the user's respiratory tract inhaled, but the air that is filtered and sterilized after inhalation forms a vertical laminar flow in the direction of gravity and flows indoors. This relates to a device that blocks the airborne spread of infectious diseases that can smoothly block the airborne viral spread indoors as the probability of inhaling the virus indoors decreases through supply.
  • one of the infection routes of infectious agents such as viruses or bacteria may be airborne.
  • Airborne transmission is when the infectious agent spreads through the air through droplets and aerosols discharged from an individual's nose and mouth to the respiratory tract of another person.
