Most face masks won’t stop COVID-19 indoors, study warns
“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,” says study leader Serhiy Yarusevych, a professor of mechanical and mechatronics engineering, in a university release. “However, there is a very serious difference in the effectiveness of different masks when it comes to controlling aerosols.”
Really? Who would have ever thunk?
Researchers theorize many people wear masks that don’t fit their face properly. As a result, many cloth and surgical masks only filter about 10 percent of exhaled aerosols. The rest make their way past the mask, most through the top, and spread into the surrounding environment. Conversely, higher-quality, more expensive N95 and KN95 masks filter over 50 percent of all aerosol droplets.
In light of these findings study authors recommend that everyone wear a N95 or KN95 mask if possible whenever indoors in the company of others.

Many of us have known this stuff very early on. I even posted about this early last year into this scamdemic and stated how critical if was to not only wear the right mask
but even just as importantly to wear it correctly, otherwise you're spinning your wheels.
And to fit your face to one of the above mentioned masks is not an easy task either! Takes a lot of practice.
