Cover Story: In the current respiratory COVID-19 pandemic, airborne virus-laden aerosols are considered as the primary route of transmission of SARS-CoV-2 pathogen. Staying in the air for a long enough time (minutes or hours), aerosol particles can be transferred over a long distance in an indoor environment to be inhaled by a susceptible host. Face cover masks are currently treated as the best accepted personal protective equipment (PPE) in mitigating aerosol dispersal. The material barrier of masks makes it uncomfortable to wear them in certain situations. The individually portable air curtain is a non-material barrier based, highly effective, PPE dynamically displacing the trajectories of infected particles that would otherwise be inhaled by an uninfected individual from reaching the surface and the openings of the host’s protected face.
