Here in northern Vermont, the temperature has been in single digits for the
last few weeks and below zero most nights. As a result, the air is so dry
that we were beginning to have respiratory problems. We can tolerate it
during the day by keeping ourselves hydrated, but at night we got all dried
out, so I looked into getting a humidifier for our bedroom.
My biggest concern was that our water here is loaded with chloramine. I
don't know much about this stuff, but the little I know suggests that it is
not something you want to breathe by putting it into an ultrasonic
humidifier. So I purchased a humidifier that evaporates the water by
boiling it. I decided that the chloramine would be left behind (true?) and
that the boiling would probably kill off any dangerous organisms.
The only problem I can see with this type of humidifier is that you have to
clean it frequently because of all the minerals left after evaporation of
the water. But it is my understanding that the ultrasonic humidifiers
deposit those minerals as "white dust" on the walls and furniture, so I
think I prefer to clean it from the device.
The other consideration was the noise level. Ultrasonic humidifiers claim
to be noiseless, but this is not true. My daughter has one and it makes a
kind of high pitched warble or whistle that is very annoying. I know that
all the evaporative humidifiers have fans, and neither my wife or I can
stand fan noise, much less sleep with it. The vaporizer type that we
settled on has no fan and only makes little "boiling" noises that are pretty
easy to tolerate.

There is one other modality where water is wicked up into a membrane and
air is blown across it to evaporate that water.
The "Swamp cooler" or evaporative air conditioner works that way.
You don't have to "boil" water to evaporate it.
If your cool mist humidifier doesn't physically direct water into a
motorized impeller to be "thrown" out the discharge, it's probably a
swamper and that is the most common type sold today with concerns over
water contaminants being inhaled by people with allergies. [or water born
bacterium and fungi]
I haven't seen a wet impeller type for decades.
Some of the ultrasonics use a biocide ion exchange resin in the water
filter..sometimes silver. [Look for the "AgION" logo ]
You may not want to run an ultrasonic without that filter unless you put
some CS in the water...or use sterile water.
If you do put CS in there, it's a good idea to remove or gut the filter
as the resins may capture the CS.

The cool mist vaporizers act either by ultrasonic or mechanical means
to break the water up into tiny droplets -- which will still contain
whatever is dissolved or suspended in the water! The water is turned
directly into tiny droplets, rather than being turned to steam first
and then condensed.
I hope that explains it. Good question!
Be well,
