The air conditioner in the Beijing office crapped out. The solution: open the windows for a few breaths of a breeze.
Unfortunately, that breeze comes with particulates. My colleague Max wears a respirator mask and, like the rest of my colleagues, keeps an air purifier humming next to the desk.
A functioning air-conditioner would make things better, and we’re working on that. nonetheless, I suspect that even if we kept our office at 68º F/20ºC, the masks would stay on.
