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.

How can I improve my mask protection from COVID-19 if I have a beard?

Certain types of facial hair, like beards, can make mask fitting difficult. People with beards can do one or more of the following:• Shave their beards.• Trim their beards close to the face.• Use a mask fitter or brace.• Wear one disposable mask underneath a cloth mask that has multiple layers of fabric.

What is an N95 filtering facepiece respirator (FFR)?

An N95 FFR is a type of respirator which removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3 micron) particles. N95 FFRs are capable of filtering out all types of particles, including bacteria and viruses.

Can I use a polyester mask during the COVID-19 pandemic?

Polyester or other less breathable fabric will not work as well, due to moisture produced when breathing. If using denim or other fabric that is being “recycled”, please be sure it is clean and in good shape. Worn or dirty fabric will not be protective.

How can I improve ventilation at home to prevent COVID-19?

What to do if my glasses are fogging up when I wear a face covering during the COVID-19 pandemic?
