I have been doing quite a bit of lathe work using a kool-mist this week and
due to cold weather have the shop closed up. I came down with a flu or
something on day 2.
They spec sheet says it totally safe, but does anyone know something
different?
Maybe just the fact that I have been breathing a lot of water vapor could
make it easier to get sick?

All the appropriate remarks about coolant vapor notwithstanding, a cold
or the flu is a viral infection. You got it by exchanging vapor with
someone who was already infected (a sneeze, a cough, by shaking hands,
or handling coins, etc.).

I guess the question would be whether or not breathing coolant vapor
gives the virus a more direct vector to your bloodstream.
