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.

Mold. You have to clean the humidifier - any humidifier - regularly. This one is a little tough to clean, so I'd recommend a bottle brush.

We use the Ultrasonic in a large master bedroom and it is very quite. I do not notice any "white dust" but we live in Southwest Colorado on the Mesa and we have plenty of dust that gathers in the house. However I don't think any of it is due to the Ultrasonic. Worth the money.

yes, using tap water with the cartridge should be just fine. The reason for the cartridge is basically to avoid white mist that's typically associated with ultrasonic humidifiers. hope this helps...

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

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.

It's a calcium build up. It'll disable your humidifier altogether if not it's not regularly cleaned. When I first bought the humidifier, I also bought a solution that was supposed to help keep calcium buildup at bay. It didn't. So now I clean the humidifier once a month by letting the heating mechanism soak overnight (or while I'm at work) in vinegar.It works like a dream. This was my boyfriend's suggestion, so I can't take credit for it. But I'll swear on a stack of humidifiers that it works each and every time.

There is a small blue light on top of the unit that is on when it is functioning. We don't even notice it so unless one is really sensitive to any light it shouldn't be a problem. The unit is very quiet and does not produce any fine dust as many units do.

Pretty sure its the white side, thats what I see when I look at the top of the humidifier where you can see the filter, white.

I would have to agree with others who posted answers. However, I have issues with white powder. I am in Phoenix and unless i use distilled water, the tap water supply here is too hard for the filter that is built-in to the humidifier to handle. This is not by any means a bad thing, since I have the same issue with all other humidifiers i have tried (like 15 or so) and they all had the same issue. But there is no issue with wetness with this unit.

I do not have that problem with mine. It does not leave a powder in my rooms, but that may be because I follow the directions about leaving doors open so the humidity can go where it needs to. Also, I alternate between the lower and high settings. This is a good, basic cool humidifier - I am happy with it.

The same here. I know I turned down the level of water added to the air this year becsue I found mold in the attic. Have you changed the pad in the machine as ours was coated with minerals which may inhibit the humidifying action.

I don't have answer for this question. But I should let you know that this one was broken within two months. Then I had to buy another humidifier.

I'm using the electric blower to clean it once in a while. It surely does collect dust and white color becomes gray!!

Unacceptable that your humidifier beeps all the time--Send it back to the manufacturer (we had to do this once) and get a refund (or your humidifier back!Good luck! Joan

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.

Make sure the seal is tightened all the way; I purchased 2 humidifiers with no issues.
