How does Covid-19 spread?

  • Via air & direct contact. Specifically, via large droplet transfer (coughing/sneezing and with some folks, strong exhalations).
    • Most droplets don’t stay suspended in air for long, due to their mass.
    • That means they tend to fall on surfaces, where they can remain viable anywhere from a few hours to several days (according to the World Health Organization).
  • If an infected person coughs or sneezes into their hand and then touches a surface that another person comes into contact with, the virus can spread.
  • Airborne transmission, while less likely, is also possible.
    • Some droplets may be small enough that they stay in the air and enter an HVAC system.
    • From there, they could spread to other parts of a facility and infect people.

Do HEPA Filters Help?

  • While HEPA filters are excellent choices for trapping 99.97% of particles down to 0.3 microns in size, coronavirus is even smaller – between 0.06 and 0.14 microns. Therefore, filtration alone isn’t enough. ASHRAE recommends using UV-C disinfection, as well.
