Indoor Air Quality & COVID-19

When people infected with COVID-19 cough, sneeze, speak, or exhale they release virus particles that can linger in the air for several hours. You can reduce the risk of COVID-19 transmission by taking steps to improve your home's indoor air quality.

In your home reduce the concentration of airborne virus particles by ensuring proper ventilation with outside air.

  • As weather permits, open windows and screened doors to increase the outdoor ventilation rate.
  • Consult with an HVAC professional to determine what HVAC filter would optimize your ventilation rate.
  • Supplement ventilation by purchasing an air cleaner (air purifier) and placing it in rooms where more targeted filtration is needed.
  • Run your HVAC system continuously and turn off automatic controls that reduce air supply once a certain temperature is reached.
