Can portable air cleaners prevent the spread of COVID-19 indoors?

There are various measures to reduce the risk of exposure to the virus that causes COVID-19 from spreading indoors and generally fall into three main categories: source control, ventilation control, and removal control. Source control means reducing the number of people in the enclosed space (1). This enables social distancing, which reduces the number of infected people (if there is an infected person in the enclosed space) and provides more outdoor air per person. Increased ventilation dilutes the infectious aerosols produced by infectious human pathogens.
