Air purifiers may actually help spread COVID in confined spaces

Air purifiers may actually be doing more harm than good during the pandemic — as a new study shows they could help spread COVID-19 droplets in confined spaces.

“The air purifier reduces the droplet dispersion but will not eliminate it. The air intake integrated inside the purifier equipment induces flow circulation that can add to the transport of contaminated saliva droplets in the cabin,” wrote authors Talib Dbouka and Dimitris Drikakis.
