Since face masks have become part of the new normal, many do not leave home without them. But what if you forgot to get a new one, would you still put on that used crumpled mask in your pocket? Recent research says that might not be the best option.
A study titled, Effects of mask-wearing on the inhalability and deposition of airborne SARS-CoV-2 aerosols in human upper airway published in the journal Physics of Fluids, revealed that wearing a used mask proves more dangerous than when one would not opt to wear anything at all in trying to ward off COVID-19.

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
