What is the difference between masks and respirators?

• Masks, such cloth masks or disposable surgical masks, are made to prevent droplets and particles you breathe, cough, or sneeze out from escaping your mask. If they fit closely to the face, they can also provide you some protection from particles spread by others, including the virus that causes COVID-19.

• Respirators are specialized filtering masks such as “N95s” or “KN95s”. Respirators are made to protect you by filtering the air and fitting closely on the face to filter out particles, including the virus that causes COVID-19. They can also prevent droplets and particles you breathe, cough, or sneeze out from escaping your mask, so you do not spread them to others. 

When worn consistently and correctly, both masks and respirators are effective at reducing the spread of COVID-19.
