Cloth masks provide 'least protection,' CDC says
In newly updated COVID-19 guidance on its website, the Centers for Disease Control and Prevention said that loosely woven cloth masks provide the "least protection", while masks like N95 respirators offer the highest level.
In some cases, Americans might want to opt for higher-quality masks like KN95 and N95 respirators, the agency said.
"Wearing a highly protective mask or respirator may be most important for certain higher risk situations, or by some people at increased risk for severe disease," the CDC stated.
The CDC recommendation stops short of calling on Americans to choose one mask over the other, maintaining that any mask is better than no mask.
The updated guidance comes after weeks of health experts urging Americans to upgrade their masks in the face of omicron.
