This graphic is complete BS.
In image 2, It completely ignores the actual direction of droplets. They go UP. Right past your eyes and over your head. The droplets will linger longer and at a higher level, than they would would without a mask. They don’t travel as far forward, but they last longer.
I have a theory that breathing out of your nose is better than through a mask. I plan to test it out later this week and release a video of the experiment.
Here’s my first test, several months ago: https://www.youtube.com/watch?v=X4zNYfMYg-c
Respiratory droplets (pictured in the graphic) only stay in the air for a few seconds. Yes, some droplets will be forced more upwards, but they’ll still land quickly. You’re talking an extra couple of seconds in the air.
But that’s not the point. Wearing a properly made, properly worn mask reduces both the volume and the range of the droplets that enable SARS-CoV-2 transmission. Volume is a huge component of this. Reducing it is extremely helpful.
Does the virus also exit the body thru the other orifice?
