Ultrasonic atty?

[PaulZ]

couldnt we use ultrasonic atomisers and achieve a non-heated vaporiser? it would prevent any dangers from burning fiberfill and whatnot...

i have a small humidifier that uses ultrasonic technology, and the air isnt heated at all.

discuss!

It would be nice, but unlikely to be worth the negatives:
-Vapor will not be warm
-Ultrasonic transducers can accumulate mold/bacteria
-They can "vaporize" things like dust and particles in addition to the liquid (bad for you)

Heating seems more archaic, but for how it is being used, I don't think ultrasonic is necessarily the best option.

There's been a few threads about this idea, but this is generally what it seems like people settle on.
