So which mask is best?
A new Duke University study examined a variety of masks to see which are most effective at blocking respiratory droplets to protect wearers and the people around them.
Dr. Anthony Cardillo, a Los Angeles-based ER specialist who was not involved in the study, tells Eyewitness News his clinic has been advising patients to wear simple surgical masks while out in public. If those aren’t available, cotton masks are a good alternative, he said.
He added that people should avoid masks that have valves in them, even N95 masks, as those openings allow droplets to be exhaled.
“So we want to counsel all people, everyone to be wearing a simple surgical mask when you’re out and about. If you cant get your hands on one … If you have to wear a mask, cotton mask three-ply is the third best.”
