re: Mask Facts - they don't work

At the very end of the spectrum, the researchers were shocked to find that not only were trendy face coverings such as bandanas and neck gaiters ineffective, but that they actually spread respiratory droplets more effectively than no mask at all. The reason for that, the study said, is because the thin material of the fleece splits the droplets into smaller particles, allowing them to spread more easily.

"We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask," Fischer told CNN.

Duke physician Eric Westman, another researcher involved in the study, said the findings about the less-effective masks are important because little information was available.

"They were no good," he said, according to DukeHealth.org. "The notion that ‘anything is better than nothing' didn't hold true."
