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
