I don't know if it is used everywhere but large fans with

mist are
commonly used here in outdoor places where people

"beer garden", and they also make what might be called
"room air
conditioners" that are what used to be called "swamp
coolers".

We bought one of the pressurized bottle personal misters
during one of our trips
to New Mexico. It worked well for my wife, who doesn't
tolerate heat well.

It seems noticeably less effective here in humid Ohio.
What's the typical
humidity levels where you see the water spray fans used? ...

Ummm,,,,,, in the desert.

The stark reality of evaporative coolers is that they work
best in the very places that typically don't have a lot of
water.

In places where evaporative coolers work well, some nicer
houses even have them integrated into the central
heating/cooling system. Evaporative coolers also have the
side-effect of dumping a lot of humidity into the air,
which, if you have a luxury home with a lot of fancy
woodwork, part of the warranty is that it isn't valid if you
don't take precautions to protect the interior of the home
from very-high and very-low humidity--because the pretty
woodwork will all warp and crack.

If retailers don't sell them where you live, then you
probably live where they don't work well.

If you live in a humid environment, all a swamp cooler is
going to do is make mildew grow on everything in the room.


Yeah, Coolerators are bad enough in Texas but useless in
Wisconsin or (as Frank said) Ohio.
