The Centers for Disease Control and Prevention (CDC) is preparing for the possible spread of the corona virus in the US. You can consider getting masks or a mask to cover your mouth and protect yourself. Note that the CDC before you do that does not recommend that you wear a mask to protect against coronavirus unless you already have symptoms.
But if you are in a situation where you need a mask and you have facial hair that could break the seal of that mask, look at it this handy CDC infographic, which I also included at the top of this post, to know which facial hair you can wear without breaking the seal of that mask.
In short, the CDC recommends that facial hair that fully fits under a gas mask should be good. Where it may seem that you may have some problems is if your facial hair is long enough or covers enough of your face to press against the seal of the respirator.
I love lots of images and names on the infographic. I really love Zorro, Zappa, and Walrus, and the image of the English mustache sticking out the sides of the mask makes me laugh for some reason. I will say that it is a doubtful choice to add a person with a mustache in Hitler style (sorry, “toothbrush” style), that can no longer be so common.
An important note about the infographic: it was not made as specific guidelines for coronavirus. It was first published in November 2017 to tell people who want to do No-Shave November and Movember what facial hair works with close-fitting masks. But the infographic is still fun to look at and its general guidelines apply to any situation where you need to wear a face mask or mask. And I also want to repeat that the CDC says that you do not have to wear a mask if you are already healthy.
But if you need a mask or a mask, it may not work with a beard. Instead, you may have to choose from the CDC’s other facial hair recommendations.
