Most Of Us Wear Masks Incorrectly
Vidcast: https://youtu.be/7adflrzSE5w
Eighty-seven percent of mask wearers apply them incorrectly with air leakage that could be deadly. A collaborative analysis by investigators at Singapore Hospitals and MIT looked at 714 subjects given N95 masks.
The common mask fit mistakes were incorrect strap placement and improper tightening of the mask’s nose clip. Both mistakes result in air gaps around the mask. Younger subjects and those with previous mask fit training did better. In typical American fashion, reading the instruction book or previous mask use didn’t help.
When you use a mask, any mask, tighten the straps, position the mask under your chin, and fit the mask to your nose.
