There is only one way to wear a surgical mask correctly, and that is with the coloured side facing outside.
And it doesn’t matter if you are wearing the mask because you are sick and don’t want to spread your germs; or are wearing it to prevent yourself from being infected.
The outer layer is hydrophobic or is a fluid-repelling layer while the inner layer is to absorb moisture, as the air we breathe out contains moisture.
There is also typically a middle layer that filters bacteria.
“The function of the blue/green layer is to prevent germs from sticking to it. If you wear the mask the other way, the moisture from the air will stick onto it, making it easier for germs to stay there.
“When you breathe in, the germs will transfer from the outside later and straight into your lungs, ” Bel wrote in a Facebook post in January 2019 that has gone viral again recently.
