Video compares droplet sprays when wearing different masks –

Scientists compared the sprays of droplets we spew out of our mouths when using a one-layered cloth mask, two-layered fabric mask, surgical mask, and no mask at all– while talking, coughing, and sneezing.

Mashable summarize the findings succinctly:

The research study’s huge takeaways are:

– When talking, wearing even a single-layer mask considerably restricts the exhalation of droplets.

– For coughing and sneezing, a double-layer mask is much more efficient than a single-layer mask.

– Generally, the more layers a mask has the much better. The scientists recommend “at least three layers” and discovered surgical masks performed finest in this research study– though not everyone has access to these masks.
