I would be more woried about your lungs than any electronics. Ultrasonics 
may take a bit less electric power than the old boil the water system, but 
aren't you lungs worth it? (My heat here is electric, so the cost is exactly 
the same for me if I use a boiling humidifier or an ultrasonic one.)

If you really want to filter the air, you can get an electrostatic air
cleaner. I picked up a "Norelco CleanAir IV" for about $80 at a
department store. It works fairly well on soot, smoke and very fine
particles.  It is definately useless for fibrous dust. I've had mine
running continiously for over a year now. The only real pain is
cleaning the aluminum filter plates. The fine black soot is fairly
water repellent.  Both "Fantastic" and "Formula 409" do a good job of
lowering the surface tension of the water enough to allow it to wash
this stuff off.
