As authorities continue to issue and enforce practical measures and protocols towards limiting the spread of the novel Coronavirus (COVID-19) pandemic in several countries around the world, a fresh study has concluded that cloth nose masks are not that effective at preventing transmission of the virus.

So, if you have decided to wear nose masks in public, as many jurisdictions are strongly advising, it just might pay to wear a really good one now.

Canadian researchers at the University of Waterloo discovered a large buildup of aerosol droplets suspended in the air when it had subjects wear cloth masks in a large room. The researchers found N95 or KN95 masks were much more effective at containing droplets.

Researcher Serhiy Yarusevych, who led the study, said: “There is no question it is beneficial to wear any face covering, both for protection in close proximity and at a distance in a room.

“However, there is a very serious difference in the effectiveness of different masks when it comes to controlling aerosols.”
