Most people probably won't put it on correctly, per this claim:

"I remember my respirator training, the last time I worked in a hospital. They gave the standard two minute explanation, made you put the respirator on, and then made you go underneath a hood where they squirted some aerosolized sugar solution. If you could smell the sugar, your respirator was leaky and you failed. I tried so hard and I failed so many times. It was embarrassing and I hated it.

"I’m naturally clumsy and always bad at that kind of thing. Some people were able to listen to the two minute explanation and then pass right away. Those kinds of people could probably also listen to a two minute YouTube explanation and be fine. So I don’t want to claim it’s impossible or requires lots of specialized background knowledge. It’s just a slightly difficult physical skill you have to get right...You are unlikely to be able to figure out how to use an N95 respirator correctly. I’m not saying it’s impossible, if you try really hard, but assume you’re going to fail unless you have some reason to think otherwise."
