The Centers for Disease Control and Prevention is considering a change to its mask guidance as the omicron variant of the COVID-19 virus continues to circulate across the country, The Washington Post is reporting.
The CDC will probably advise people to use the N95 or KN85 mask instead of a cloth mask, the Post reported. The N95 masks are the type used by health care personnel.
“The agency is currently actively looking to update its recommendations for KN95 and N95 in light of omicron,” according to an unnamed official the Post identified as a source close to the negotiations. “We know these masks provide better filtration.”
While many people use a cloth mask to cover their nose and mouth when they are indoors, the CDC guidance is expected to say that if people can tolerate wearing a KN95 or N95 mask all day, they should.
The CDC’s current guidance says a mask should fit snugly, be made of at least two layers of breathable fabric and have a wire bridge around the nose that helps the wearer make a more snug fit.

The masks shed virus exactly the same way you do when you exhale. They are not made to filter things smaller than 0.4 micron. That's why air goes through. They can filter mold, bacteria, other things that are larger than those, but they CANNOT stop viruses, or even reduce them enough to change the R-Naught numbers.
