What about these ultrasonic humidifiers? Are they any good? Do they really need demineralized water? I seem to remember at one point there was a health hazard associated with them. I need some kind of unit for my daughters bedroom, she has eczema and we need to make sure the RH is kept in the normal range. Thanks Eric
We have very hard water, they do indeed need soft or demineralized water. During the summer I use A/C condensate, during the other times, I use rainwater poured through cheesecloth. Gerber makes one, at WalMart for less than $40. As for your question of safety, the URL was too long, here are the details. ******************** Ultrasonic Humidifiers May Be a Health Hazard
BOISE: Ultrasonic humidifiers that aerosolize water pose a health hazard if tap water is used in them, since minerals and other materials dissolved in the water may be released as particles small enough to be inhaled deep into the lungs.
That is the conclusion of researchers from the U.S. Environmental Protection Agency. V. Ross Highsmith and Charles E. Rodes from the agency's Environmental Monitoring Systems Laboratory, Research Triangle Park, North Carolina, and Richard J. Hardy of Morrison-Knudsen Engineers in Boise, Idaho ... ********************

Yummy!
I have an Aprilair on my central heating system and will not consider anything else.
Agreed. Plus think about how must mold/spores you are putting back into the air! Ultrasonics do not kill the junk, it just throws it out in the air to evaporation.
Yuck!

My inlaws do vent duct cleaning. That manufacture makes them lost of money doing duct replacement, after the owner sees what highly moist air grows in the darkness of ducts.
Muahahahahaha
My system shows no evidence of mold in the ducts or any area around the humidifier. That is one reason I recommend them.
I just have to say it, but let me start by saying it is not true of all. Many of those doing duct cleaning work on the unreasonable scare method of sales.
Oh, for you, I promise to let it sit around for a couple of weeks before I use it.
