PROPER USAGE:If worn properly, a disposable mask is meant to help block large-particle droplets, splashes, spray or splatter from coughs and sneezes.
While a disposable mask may be effective in blocking splashes and large-particle droplets, a face mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Disposable masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and your face.
Disposable masks are not intended to be used more than once. If your mask is damaged or soiled, or if breathing through the mask becomes difficult, you should remove the face mask, discard it safely, and replace it with a new one. To safely discard your mask, place it in a plastic bag and put it in the trash. Wash your hands after handling the used mask.
These masks do not supply oxygen.
