BOCA RATON, Fla. (WFLA/NBC) – Health officials continue to stress the need to wear face masks to help reduce the spread of COVID-19.
A new study is shedding light on which types are most effective for containing the virus.
Researchers used a laser to detect droplets as they were coughed and sneezed out of a mannequin head.
They found that loosely folded face masks and bandana-style coverings had little to no effect on stopping stopping the droplets.
But well-fitted homemade masks with multiple layers of quilting fabrics and off-the-shelf cone-style masks were the most effective.
The scientists said the mannequins projected droplets much farther than six feet when they didn’t have a mask on.
