Wearing Masks or Respirators
Masks are made to contain droplets and particles that you breathe, cough, or sneeze out. A variety of masks are available. Some masks provide a higher level of protection than others.
Respirators (for example, N95) are made to protect you by fitting closely on the face to filter out particles, including the virus that causes COVID-19. They can also block droplets and particles you breathe, cough, or sneeze out so you do not spread them to others. Respirators (for example, N95) provide higher protection than masks.
When wearing a mask or respirator (for example, N95), it is most important to choose one that you can wear correctly, that fits closely to your face over your mouth and nose, that provides good protection, and that is comfortable for you.
