Is white dust a problem only with sonic humidifiers?

No, I don't think so. I believe it is residue from the evaporated water. I think Ralph is correct. The harder the water, the more residue.

White dust is actually hard water and yes will always happen so no problem.

White dust is caused if using tap water because of the minerals in the water. You probably have hard water. The only way to avoid this is to use distilled water.

Pretty much. White dust happens when minerals are vapors along with the water, and is essentially only a feature of ultrasonic humidifiers. In other types evaporation happens in the unit, rather than in the air after vaporisation (which is how ultrasonic units work-they're vaporizers rather than evaporators). Heat and wick units get scale in the unit, instead of white dust. Makes it easier to clean, since it's all in one easy plat.

Have you cleaned it. I use distilled water so I don't have to worry about mineral build up. I also have a water distiller which paid for itself in one year. you will also get a white powder over everything with a sonic humidifier with water from the faucet, especially if you have a water conditioner.. I clean out my sharper image humidifier half way through the winter. if you bought it from Sharper Image, they are very good about replacing items that stop working. sorry if this doesn't help.

Mine works beautifully with no dust issues, but I would see what the others say.

This humidifier was a bust for us. We've never used a humidifier that created as much white powder/dust as this one. To the point that we no longer wanted to use it and replaced it with previous brand we had used.

Yes I had the same problem and ditched it and found a better humidifier. Our unit leaked from the very same spot. Other people have had the problem. We've had this one for about 6 months: Crane Drop Shape Ultrasonic Cool Mist Humidifier with 2.3 Gallon output per day and it seems to be working well. No filters. It's a little bit of a pain to clean, but a little bleach solution and voila, it's clean. For our needs, this has been a much better humidifier and NO LEAKS!!!!

You did not do anything wrong. My unit worked the first time or two and then leaked from the bottom. I believe the humidifiers are poorly designed.

This is my review:1.0 out of 5 stars Doesn't work, January 17, 2015 By Holly "Healthnut" (Provincetown, MA) - See all my reviewsVerified Purchase(What's this?) This review is from: HoMedics UHE-HDC4 Ultrasonic Humidifier Demineralization Cartridges (Misc.) Didn't work at all. White dust all over all hard surfaces in the area. Used it with Homedics cool mist ultrasonic humidifier model #UHE-CM25

Reading about humidifiers, ultrasonic humidifiers put quite a bit of white dust into the air. You would have to have naturally very soft water. NOT water softener water. Or use distilled water. Very expensive.

I have the Hello Kitty model and the same thing happened. For some reason the fan gets misaligned even though I have it on a flat surface and it hardly moves. I called Crane and if you are under warranty they will replace it. I think it may be a flaw in most of their humidifiers, I have gone through 3 of them already due to the same problem every time.

My humidifier has none of those problems, so you must have a defective unit. The only drawback I've experienced is when I fill the tank and put it back in the unit, and the bottom of the tank snags on the filter. I have to help the tank get into place past the filter, but everything works fine after that.

We're using the unit in a room that's about 420 SF, but it also has a 10 ft ceiling. I fill the unit up twice a day, about a gallon each time. We've had no problems with dry air symptoms although the humidity ranges from 32-42%. The unit is very quiet, particularly compared to our previous humidifier, and we've seen no white dust. We do use the recommended demineralization cartridge (Kaz DC-51) and the antimicrobial cleaning cartridge (Protec PC-1) to help with keeping the unit clean and because of our hard water.

If you sanitize it on a regular basis, once to twice a week, there should be no dust. The humidifier sucks air in through the bottom and filters it through a filter which is damp and due to the filter the air that comes out is cleaner than the air going in. Hope this helps. Its a good product and amazon has replacement filters for it 3 for $30 i think. I like this humidifier and recommend it.

I would contact Essick. Last year my humidifier didn't work but just groaned when I first started it. It was only the second year I'd had it. I called Essick and learned that the year before, the motors were defective in a group that had been sold. Because I had my receipt which I faxed to Essick, a new humidifier was sent to me a no charge. It worked well last season and is working well this season with new filters. I doubt that your problem is a filter issue. Good luck.

white dust is probably referring to mineral deposits, if this is the case then it's the fact that you have hard water that causes this and not the humidifier.

I have 2 humidifiers and used both these upon arrival about 3 weeks ago. So far no "white dust". However we also have a whole house water filtration system which may help also. These are way easier than using the bottled treatment and the humidifier and wick are staying much cleaner.

Yes it does leave white powder on everything. It is not super loud but I have had quieter humidifiers.

Unfortunately, while this is a decent humidifier, what you mentioned is an annoying problem with it. I have bought two and have the same problem.
