Does this unit leave white dust?

No, no white dust of any kind. The white dust is usually a problem with ultrasonic humidifiers. This one is an evaporative type, where all hard particles in the water sink to the bottom.

I have owned this one for about 6 months and have not experienced any white dust. I am very happy with the performance of this unit.

Since we used this unit in the carpeted area, I cannot say for sure that this unit does not leave any white dust. But we did not have any problems so far.

Definitely! The unit itself is all cased in, so no random bugs and dust can get in!

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 was curious to see if mine was also dirty. It was. I couldn't remove the white plastic front, but I blew into the wider opening and it seemed to get rid of just about all of the dust inside. Now I am keeping mine in a ziploc sandwich bag to prevent the build up of dust.

What may appear as white dust may be from the water source that has dried. The water in the area that I had to use in the unit also left a similar residue, but it is not harmful. It has to do with the area having hard water and me not choosing to use distilled water for the unit. If you are extremely concerned and financially capable, you may choose to try distilled water, change your filter, run bleach through the system and see if the effect is still noticed.

This is what I bought the unit for. My cat's litterbox is in our bathroom. I placed the purifier in the same room, and cleaned the filter every 2-3 weeks. After about 6 months I started to smell litter dust more than usual. I removed the filter and looked inside the unit and noticed that all of the components (wires, fan, etc.) were covered in fine dust. I don't know how long it was pouring the dust particles back in to the room, but I stopped using the unit immediately after that. Not sure if this is something that would be covered by their warranty.

I don't know. I run it continuously, but so far it has not accumulated any significant dirt/dust.

Yes...it does. Note these are the best units I have had so far. The other very popular ones crap out within a year and give a false alarm.This is due to the manner in which the smoke particles are sensed. Photoelectric and ionized particles.Bill

I honestly do not know. I use a Frebreeze feather-type cleaning cloth to remove the dust particles located on the front of the unit.

There is no white dust.White dust happens with no fan no heat humidifiers.This is a room cooler.

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.

We have both kinds. The white one can see collected dust better, when you clean it. The black works just as good, but you don't see that much dust on filter.collected

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.

I only used mine for a couple of months before I replaced it due to all white dust.

I run one of these 24x7 in my son's room and I leave the PlasmaWave turned off. It still filters fine, and I notice alot less dust accumulated dust around the unit. When the plasmawave is one, I get a fine white powdery/dusty stuff that gets all over the front plastic removable cover and the table it sits on.

No this is not common. I have had my Venta humidifier for 4 months and replaced the cartridge once and have not had any issues or white dust. I would contact customer support. Good luck.
