When putting the mask on, place shiny side to face. The contrasting color seam, known as a bar tack, should be near the chin. Put loops over ears, and adjust to cover the nose and mouth. The mask should be snug but comfortable.
To remove the mask, avoid touching the outer layer of mask or face. Remove from ears, only touching loops, and immediately put into washer, sterilizer, or safe storage. It is best performed under adult supervision. Avoid putting the face mask around neck or forehead.
Clean mask by washing or sterilizing before each use. Sanitize hands immediately after handling worn masks each time. Clean after multiple use or if soiled. Discard if damaged or torn.
