Aerosols and Micro-droplets: HVAC Approaches During COVID-19

In July 2020, 239 scientists urged the medical community and public-health authorities to acknowledge the potential for airborne transmission of SARS-CoV-2, the virus that causes COVID-19, and promote additional precautionary measures like increasing ventilation in indoor, enclosed environments. By implication, they suggested that HVAC systems have a role to play in combatting this virus in light of mounting evidence that it may be transmitted by aerosols.

But still, select health organizations, including the World Health Organization (WHO), did not recommend control measures for combatting an airborne SARS-CoV-2.
