Face mask to protect against airborne viruses like coronavirus. Mask is not a one-size-fits-all solution, requiring different scales to determine the best fit.

Optional: 1) Use a hair dryer to heat up the edges and contours to your face. 2) Initial your masks in case you have more than one in the family.
