We had ultrasonice humidifier for years. The problem was when we use it for a while the surface of our home had white dust. Does this like that?

I got the white dust eventually, but I did not change my filter as recommended.

We live in Florida and have very hard water. We have followed the instructions EXACTLY, and have yet to have "white dust". Be sure to change the cartridge (which screws onto the water tank cap), as per instructions. We really LOVE this humidifier!!

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.

Master plumber came and installed my humidifier. I asked him the same question you have for me. He said that you will go through a few more filters a year, but not substantial. He also said that that is a good thing because the dirt the filter is catching would be in your house otherwise. The reason is now that you have a higher humidity % in your house the dirt sticks better to the filter and is cleaning your household air better. I agree after one day. The air just breathes clean. Hope this helps and I am satisfied with my unit.

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

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 put the drops of essential oil in with the water. I've only had mine for about a month and I've not had to clean it yet. I've noticed it stays cleaner than the last humidifier we had. I don't think there was a warranty but I am not positive.

Yes there is a very large filter in the center of the unit. It needs to be changed periodically. The filter will turn brown and get stiff. There's an indicator light when the filter needs to be changed. I had unit a humidifier without a unit and it left a white film over my furniture and floor. I got rid of that one!

I noticed an interesting odor when I first started operating the humidifier however that subsided within a day or so. Almost smelled like new plastic if that makes sense. Hope this helps!

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.

This is my review: 1.0 out of 5 stars Doesn't work, January 17, 2015 By Holly "Healthnut" (Provincetown, MA) - See all my reviews Verified 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

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 used mine extensive last year for about 4 months and it needed minor cleaning monthly and again before putting it away. Even with the bacteriostatic solution it got a bit slimy were the water sits but none of the nasty mineral crystals like other types of humidifiers. Warm soap and water, or a quick run in the dishwasher is fine and you don't need to cycle vinegar through it like a coffee pot, very easy. I was surprised at the length of use I got out of the filters and how cheap it is to use generic filters cut to the proper length.

We have used this Humidifier for about 6 Month and use it often but not every day, we use distilled water and so far see no reasonto clean it, it works really well. Hope this will help

No, not a bit. It doesn't have that ionic feature. I do use water from our reverse osmosis water filter system, but the humidifier is not the type to put out that dust. I believe that's more in an air purifier or air filter, not a humidifier.

Not that I have noticed. It does get a film on the inside if the humidifier but a cleaning once every couple weeks takes care of that.

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.
