Apparently, there is controversy over the safety of ultrasonic humidifiers. Unlike other types, they apparently put large amounts of particulates into the air (mold spores, pollen, minerals, bacteria). I heard (maybe a rumor) that the FDA has even considered recalling them. I thought they were mighty neat devices, but mine is now packed away... Paul

They do put out a lot of dust, but it is sterile dust -- the intense ultrasound kills anything in it. That was the situation last I heard, anyway. -- 1972: Saturn V #15 flight-ready| Henry Spencer at U of Toronto Zoology 1990: birds nesting in engines | uunet!attcan!utzoo!henry henry@zoo.toronto.edu

I use high mineral water that has gone through a reverse-osmosis water filter in mine. I've never had any white dust. Proper care and water should eliminate mold, bacteria and minerals. As for pollen, just keep the flowers out of the water container and that shouldn't be a problem.
