i used the ultrasonic ones over the years: they die from dust (fan clogged), minerals in the water accumulating (yes, user cleaning error) , hard to reach places to clean mildew (or in couple cases black mold). they smell even with daily use (warm/room temp water).
not adjusted right will wet (condensation from cold surfaces+carpet/rugs/walls/furniture) and get white dust all around them
i think i had all the cute crane zoo (and a winnie pooh).
now have couple units a little simpler with the nooks and crannies. wife got them at bed bath and beyond.
i'm in charge of cleaning and filling with water/setup. they seem better then the previous trials... (wet furniture/output/cleaning -wise)
also used couple hot steam units. returned either because of boiling water noise, or clogged from minerals in old pipes city water.
the cold evaporation systems i used, died from broken fans, too expensive filters (they got mildewy/smelly quick, even with mildew control in water, so with daily use you pretty much have to change them monthly/bi-monthly, even with weekly cleanings)
oh, and just for the record (user error) DO NOT USE scented oils/perfumes in todays plastics!!! usually they will attack the plastic, cause malfunctions, start the mildewy germs/goo. (it was sleep-deprived parents attempt at getting cold-hit kids to sleep better; i hate eucalyptus/pepermint/vicks-cold oils)
P.S. most of the units are not made for you to open them repeatedly to clean them/fans. my experience stand at mostly 20-30-50-80 bucks.
