I don't know if it is used everywhere but large fans with a "water
spray" system attached so that they blow a sort of fine mist are
commonly used here in outdoor places where people accumulate. Think
"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? Maybe I should rig
up something like that for our sunny patio, for next summer.

I've seen them used in Thailand and Singapore. Singapore has an
average temperature of 82.5(F), 166 days of rainfall and an average
humidity of 80%. Thailand has an average humidity of 79.9%, average
annual temperature is 89.6(F) and averages 130 days of rain (average
whole country).

Quite a lot of open air type of places have them and my experience was
that it made it feel cooler, but I don't know whether it actually
lowers the temperature appreciable.

The first ones of these I saw was a ring of, maybe, 1/4" tubing
mounted on the face of a 24" fan, similar to
A piece of 1/4" copper tubing and one could make his own at least well
enough to see whether they were practical.

My wife has a evaporator type of room air con (swamp cooler) and it
blows cool air... or at least it feels cool, even during a downpour.

Re make your own. The first ones I saw were simply a tube ring with
small holes drilled in inner diameter of the tubing aimed straight
across the face of the fan. No nozzles as in the Amazon version.
