Does this unit create "white dust" as a part of the output? That is, a residue that can be noticed on furniture etc.

No, none at all. That was one of the reasons I purchased this type of unit.

The white dust is a problem with ultrasonic humidifiers. Since this is evaportative, it is not a problem. Mine works very well

I'm using this humidifier for the 2nd year and I have not had any "white dust". The water in my apartment is very hard water, and their is a lot of mineral deposts that get left on the filter, so I have to change the filter more often. Maybe the filter is good enough so that you don't get "white dust"?

This is the second winter I have used mine and I have not seen any "white dust".

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.

No white dust with this unit. This is an evaporative humidifier where the filter soaks up the water and the fan draws air through the wet filter. The air retains some of the moisture as it passes through the filter. The minerals are left behind in the filter. The white dust is produced by ultrasonic humidifiers that use a device similar to a speaker to vaporized the water. the minerals in the water vaporize also and later settle out on everything as a coating of white dust.

Jeff, I would have to say no, because I never saw any. After reading all the other answers - I still say no, and I use water right out of the tap. The one at the apartment is city water, but one at the house is drilled well water and neither of these humidifiers leave white dust.

Mine has started doing the same thing, only it worked really well for a few months. I think it's because I wiped the inner circle on the bottom, which the instructions say not to do. I did it lightly, because I want it clean, but apparently, this ruins the unit! VERY frustrating because now I have to buy a new one!

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

I haven't cleaned mine yet but it is dusty, I will use the brush attachment from my vacuum, but the aerosol can used to clean computers also seems like a good idea!

I sprayed the carpet throughout my entire apartment with no problems. I have a computer in my bedroom, and it was not affected at all. I don't own a flat screen TV. After spraying, I opened some windows, and waited outside for a while for the fumes to subside.

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

I'm happy with the unit, however, it seems the unit puts out a vaccumn cleaner smell that I do not like. Otherwise very fine unit. mo

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

I have not noticed this with mine. However, I used it in a small apartment for one winter. I have not used this in nearly two years.

Am not sure what you mean by 'white dust.' If you have very hard water that leaves a calcium residue on the pad and it runs without water in it than I guess that 'white dust' could occur. Our well water has calcium and lime in it but not in abundance. I change the filter about twice during the season and start out the season with a new filter. It runs cleaner and works better by changing the filter when it seems to run but the humidity drops. Very happy with this humidifier.

Every now and then I take my unit apart (remove screws from feet and slide out) and blow the dust from inside the cabinet. clean with damp cloth...allow to completely dry. reassemble. Do this only if cleaning the ceramic plates doesn't help. Make sure it's NOT PLUGGED IN. Be very careful. High voltage inside.

So pleased with this unit. No white residue I seen from all over humidifiers. The unit works well. The usual dust without this air cleaner has decreased considerably and that I am positive about because I am in such a habit of wiping down all furniture and vacuuming daily. This unit is perfect for my large bedroom. Will be purchasing two more.

It does not advertise this feature, nor does it appear to do this. Its primary function is to prevent mold and bacteria. However, this company has a model that sits outside of the tank (in a designated place in some units) that is for white dust. Check out model DC-1. Also, distiller water won't create white dust if that's an option for you.

Perhaps the 2 ceramic plates are dirty and/or the unit is packed with thick dust where the plate slide in. I have found this to be the case with my unit.
