Face masksHealth officials recommend wearing cloth face masks anytime you’re in public and might come in close contact with others. More than a dozen states now require cloth face coverings to be worn in places such as indoor businesses.

But different types have different levels of effectiveness, according to researchers at Florida Atlantic University.

They compared four types of face masks commonly used by the public: a stitched mask with two layers of fabric, a commercial cone mask, a folded handkerchief, and a bandana. Researchers tested each to see which would likely offer the most protection if someone coughed or sneezed.

— The stitched mask with two layers of fabric performed the best, with droplets traveling only 2.5 inches.

— With a cone-style mask, the droplets traveled about 8 inches.

— A folded handkerchief performed worse, with droplets traveling 1 foot, 3 inches.

— The bandana gave the least amount of protection of the cloth masks tested, with droplets traveling 3 feet.

— Still, any kind of cloth mask is better than none, the researchers found. Without any covering, droplets were able to travel 8 feet.

“People need to know that wearing masks can reduce transmission of the virus by as much as 50%, and those who refuse are putting their lives, their families, their friends, and their communities at risk,” said Dr. Christopher, director of the University of Washington’s Institute for Health Metrics and Evaluation.
