Wearing a used mask could be worse than no mask amid COVID-19 - study | 16 Dec 2020 | Wearing a used mask could be more dangerous than not wearing one at all when it comes to warding off COVID-19, a new study has found. A new three-layer surgical mask is 65 percent efficient in filtering particles in the air but when used, that number drops to 25 percent, according to the study published Tuesday in the Physics of Fluids. Researchers from the University of Massachusetts Lowell and California Baptist University say that masks slow down airflow, making people more susceptible to breathing in particles and a dirty face mask can t effectively filter out the tiniest of droplets. It is natural to think that wearing a mask, no matter new or old, should always be better than nothing, said author Jinxiang Xi. Our results show that this belief is only true for particles larger than 5 micrometers, but not for fine particles smaller than 2.5 microm

Study: Wearing A Used Mask Is Potentially Riskier Than No Mask At All
A new study published in the Physics of Fluids scientific journal demonstrated wearing a used mask is potentially riskier than wearing no mask at all.
According to researchers from the University of Massachusetts Lowell and California Baptist University, a three-layer surgical mask is 65 percent efficient in filtering particles in the air. That effectiveness, however, falls to 25 percent once it is used.
“It is natural to think that wearing a mask, no matter new or old, should always be better than nothing,” said author Jinxiang Xi.
“Our results show that this belief is only true for particles larger than 5 micrometers, but not for fine particles smaller than 2.5 micrometers,” he continued.
