Is there studies that determined how the effectiveness of masks degraded when improperly worn?
That'd be interesting to read. My gut feeling is to say if you wear it over your nose and mouth, even incorrectly, it is still better than nothing. But sometimes, intuition is wrong.
Yup. A n95 with a proper fit is really the only mask that is going to actively protect you. Every other mask acts to mitigate spread from you.
And many people don't wear their masks properly, so it still really only protects others from them.

I mean, it's like condoms. Pretty effective when worn correctly.
A mask needs a seal to work properly. It doesn't matter what filtration you have if air is getting in other ways.
Considering how air work vs fluids, I'd say there is a difference.
I agree with you that for a complete protection, a sealed n95 is the way to go.
If you wear your mask improperly, will the viral charge that spread be the same? Some should stay strapped in the mask.
But anyways, it was a small bubble
