Are Knit Face Masks Safe

What kind of mask should I wear during the COVID-19 pandemic?

See full answer

Omicron is the most contagious variant we have come across yet, so high-quality, well-fitting masks are more important than ever. This is true for everyone, and even more so for anyone who is unvaccinated, at increased risk for severe illness, or caring for someone with COVID-19.

Not all masks are created equal. High quality KN95, KF94, and N95 masks have the tightest fit and the best filtration. Surgical masks are also effective at filtering out small viral particles. You can wear a cloth mask on top of a surgical mask to improve the fit. Or, you can adjust a surgical mask for a tighter fit using a method called “knotting and tucking.” To knot and tuck a surgical mask, knot the ear loops of a 3-ply face mask where they join the edge of the mask, then fold and tuck the unneeded material under the edges.

Do face shields provide the same level of protection as face masks during the COVID-19 pandemic?

Unfortunately, though, shields don’t deliver the same protection as masks. Shields do not absorb the droplets in your breath the way a cloth face covering does. They merely deflect some of the droplets downwards.
