Some infectious diseases, including COVID-19, are primarily transmitted via droplets and aerosols. Droplets are larger in particle size and settle to the ground faster due to gravity (3-6 feet) [3]. Aerosols are smaller in particle size and remain airborne for relatively long durations. The aerosol particle size has not been conclusively defined and reportedly ranges from less than 5 µm to 50 µm [4]. Larger particles can carry a higher quantity of viral load and are more likely to be deposited in the upper airways. In contrast, particles smaller than 10
