How to Wear a Mask: Good Fit and Good Condition

Good Condition: All masks should be clean, dry and in good condition. Before using your mask, check that there are no tears or loose straps. Make sure your mask is clean and dry. If your mask is washable, be sure to wash regularly. If disposable, throw away the mask when it is dirty, damaged, or difficult to breathe through.

Good Fit: no matter which mask you wear, ensure it fits well with no gaps. Gaps can happen if the mask is the wrong size, if it is worn incorrectly, or if it is work with facial hair.

Cover your nose and mouth with the mask. 

•	It is important to check that the mask fits snugly over your nose, mouth, and chin.
•	All masks should have a nose wire to secure the top of the mask tightly around your nose.
•	Make sure no air is flowing from the area near your eyes or from the sides of the mask.
•	If the ear loops are too long, knot them on each side to make them smaller
•	If the mask itself it too big, fold and tuck the unneeded material under the edges.
