These Are the Best and Worst Face Masks, Ranked by Science

Best Life Logo By Sage Young of Best Life | Slide 1 of 13: If you're not already donning a face covering every time you go out in public, you should be. But how do you know whether the kind you're using to cover your nose and mouth is doing anything to slow the spread of the coronavirus? For a study published by Science Advances, professors at Duke University designed a test that would help them to count the amount of respiratory droplets (where coronavirus particles live) that escape from several different types of masks and face coverings whenever the wearer speaks. Using a black box, a laser, a cell phone camera, and an algorithm, researchers ranked face masks by their ability to block droplets, and there were some obvious winners and losers. From the worst to the best face masks, here's how the results shook out. And for more on which kinds to avoid, You Could Be Kicked Off an Airplane for Wearing This Face Mask.
