I think you are being too harsh on the ultrasonic humidifiers.  They are
not noted for mold/etc. problems (certainly mine has nothing visible along
those lines, and it's virtually never cleaned), and the ultrasound appears
to sterilize the mist it pumps out.  The dust is a nuisance, but a simple
dust cover keeps it out of the one or two things that I really don't want
dust in.

I believe you can get ultrasonic humidifiers that have a filter cartridge
to purify the water on the way in.  (It needs replacing now and then, of
course.)

I used to do something along those lines.  An ultrasonic humidifier is
considerably better, in my opinion.  (Note that I don't have significant
allergy problems, which might change things.)

PS Have you considered the mold, amoebae, etc. that are probably growing
in your baking pans?
