N95 face masks are the gold standard in terms of protection. But N95 masks continue to be in limited supply, so they’ll be difficult to score for the time being. The issue then is how to spice up your cloth or surgical face masks, said Onyema Ogbuagu, a Yale Medicine infectious disease doctor and principal investigator of Yale’s Pfizer COVID-19 trial. KN95 masks are thought to be pretty good alternatives to N95 masks in non-clinical settings. (Tip: if your surgical mask is loose, try tying knots in the ear loops to keep it taut.)
