I’m not a doctor, but isn’t this a lost cause?

The masks we all wear are primarily droplet guards, not air filters, they catch splatter that might float. All of the air that blasts out the back and escapes is barely going to be diverted by another mask after it’s already escaped the other mask and has had time to exist, right?

I guess for my threat analysis, if you’ve already invited them inside your house and they’ve stayed long enough that you think their breath particulates are floating in the air, you’ve already lost the war, so to speak.

Probably just a few minutes will be all that matters, I suspect. If you like, go take a walk and wait for the droplets to land?

That's why ventilation is important if you are sharing a room with other "external" people.
