The CDC has updated information regarding ventilation of residential, business and school buildings. One of the updates includes a simple to use Interactive Ventilation Tool. Use this program to see how particle levels change as you adjust ventilation settings, and learn how to decrease the level of COVID-19 virus particles during and after a guest visits your home.

Small particles that people breathe out can contain virus particles, including the virus that causes COVID-19. If a guest visits your home, improving ventilation (air flow) can help prevent virus particles from accumulating in the air. Use as many ways as you can (open windows, use air filters, and turn on fans) to help clear out virus particles in your home faster. Good ventilation, along with other preventive actions, like staying 6 feet apart and correctly wearing masks, can help prevent you from getting and spreading COVID-19.
