Frequent Questions

Carbon Dioxide

Intensive Care Unit physician Greg Schmidt, MD, from University of Iowa Health Care tests whether face masks impede your breathing or make you retain carbon dioxide.

Takeaways:

  1. Face masks do not decrease your oxygen intake
  2. They also do not make you retain more carbon dioxide than usual
  3. Oxygen and CO2 are very small, so they can easily pass through a face mask
  4. Droplets are much larger in comparison, and they cannot pass easily through a face mask
  5. Wearing face coverings now helps us get back to normal sooner

Legionnaires' Disease

"Is it possible to get Legionnaires’ disease from wearing a face mask or wearing a cloth face covering that hasn’t been washed?

You cannot contract Legionnaires’ disease from wearing face masks. Legionella bacteria is transmitted by aspirating drinking water or breathing in water droplets. Legionella  is not spread from person-to-person in respiratory droplets nor does the bacteria survive on dry surfaces. Your mask would not be a source of transmission for the Legionella bacteria."
