Cloth face masks can be as effective as surgical masks in reducing transmission of COVID-19
Researchers from the Universities of Bristol and Surrey have found that well-fitting, three-layered cloth masks can be as effective at reducing the transmission of COVID-19 as surgical masks.
At the height of the COVID-19 pandemic, 139 countries mandated the use of face coverings in public space such as supermarkets and public transports. The World Health Organization also advises the use of face coverings and offers guidance on their effective features. Face coverings suppress the onward transmission of COVID-19 through exhalation and protect the wearer on inhalation.

While the Centers for Disease Control and Prevention (CDC) and President Joe Biden on Tuesday announced that fully vaccinated people can go without masks while outdoors, officials noted that there are still many instances in which a mask is necessary, including in crowded settings. As such, research continues into which face coverings are most effective, with a recent finding suggesting that multi-layered cloth masks are as viable as surgical masks.
The team, made up of researchers from the Universities of Bristol and Surrey, went so far as to say that if both an infected person and a healthy individual are both wearing well-fitted masks, cloth or surgical, there is a 94% less chance of coronavirus exposure.

In a paper published by the
Physics of Fluids journal, the researchers detail how they looked at how liquid droplets are captured and filtered out in cloth masks by reviewing and modelling filtration processes, including inertial impaction.
