Improve Ventilation at Home

Improving ventilation at home can help protect you and others from getting and spreading COVID-19 and other respiratory viruses.
Here are some ways you can improve ventilation in your home:
  • Bring as much fresh, outdoor air into your home as possible—for example, open windows
  • Consider using a portable air cleaner
  • Use fans to improve air flow
CDC’s interactive tool can help you see how much you can improve ventilation in your home.
