Due to new, more contagious variants of COVID-19 emerging in the U.S., medical experts are recommending the use of N95 or KN95 masks.
These masks can filter a higher percent of particles in the air than surgical masks or homemade cloth face coverings.
N95 and KN95 masks are held to different standards, though, so you need to be careful in deciding which is right for you.
You've probably been wearing a mask when out in public for a majority of the COVID-19 (coronavirus) pandemic, but are you still wearing the right one? Since new mutations of SARS-CoV-2 (the virus that causes COVID-19)—like the Delta variant, and now Omicron—are even more contagious, it's important to wear masks with a high-filtration capacity and a snug fit. N95 and KN95 masks best fit that bill.
