Using these face masks is easy. Just put the mask over your nose and mouth, and loop the earbands around your ears to secure it. Make sure the mask fits snugly against your face. When it comes to safety, don't reuse a disposable mask. Throw it away after one use. Also, if the mask gets wet or dirty, replace it right away. To keep yourself safe, store the masks in a cool, dry place away from direct sunlight and moisture. This will ensure they stay in good condition until you're ready to use them.
