The US Centers for Disease Control and Prevention is currently experimenting to find out about the effectiveness of wearing two masks. However, what is most critical is that as many people as possible wear one, Dr. John Brooks, chief medical officer for the CDC Covid-19 Response, said during an Infectious Diseases Society of America briefing Friday.

“Experts have proposed using two masks, or double-masking, where you put a cloth mask with a very high thread count over a medical mask,” Brooks said. “When used this way, the medical mask acts as a filter and then the cloth mask over it adds filtration but also helps provide a better fit to the contours of your face and prevents leaking around the edges.”

Brooks said that there is thinking that this specific combination could block over 90% of more of the respiratory droplets, which is near the level of an N95 respirator.
