I'm in Ann Arbor Michigan, and we've been back in the office for a month now (with lots of precautions). While not as safe for others, an N95 mask isn't too bad to wear if you can get one - about the only issue is the elastic carves indentations into the soft tissue of your skull that takes several hours to return to normal - I'm kind of worried that I'm permanently damaging the bone - but I figure Doctors/Nurses do this for 8 hours/day as well. Oh, also Coffee can only be drunk on officially (socially distanced) coffee breaks. Which is kind of weird. I figure as long as everyone is wearing a mask, the office is well ventilated (we have open windows), you are socially distanced and clorox-the-hell out of everything a couple times. And we are also essentially bathing in Ethyl-Alcohol at this point. Dispensers placed around the office and people scrubbing down anytime you touch anything.

  I'm honestly curious as to what mechanism could exist on a mask that could filter air in one direction only (and also why someone would build a surgical mask to do that) - surely you want protection in both directions?

    > I'm honestly curious as to what mechanism could exist on a mask that could filter air in one direction only You could have a mask that formed a tighter seal with internal underpressure, but moves slightly away from the face allowing exhalation to escape with overpressure. Obviously, you wouldn't want that in a surgical mask, but it pretty easy to do. There are more complex variants you could do where the difference in operation is driven by the direction of pressure differential.
