I had a humidifier that left a white residue on all furnishings - especially electronics. Will this humidifier do the same thing?

I have had this humidifier for over 5 years and on my second one and have never had this problem. I do use the pc 1 cartridge each year and faithfullyflush the filter by removing it and flushing it out every couple days by putting the filter in the sink installing the stopper and running the water into thecenter of the filter until the water back flushes the filter also while the filter is out and I'm refilling the water tanks I rinse out the base then put the filterback in the base and carry the base back to where the humidifier sits and reinstall the motor and water tanks.

It has not left a residue on any of my furniture but I have also never heard of that happening,

If you have hard hard water it will make the filter in this stiff in no time; if I use straight tap water here, I will have 1-2 weeks life on a filter, then it gets too crudded up to wick the water through; no fault of the filter. If I use bottled water (I get mine in 5 gallon reuseable jugs) I get 3-6 months on a filter. If you are good about maintaining filter quality and rinsing this one out; you should have no white glurk film.

This is an evaporative humidifier. The ones that cause the white residue are mist humidifiers. Evaporative units blow air across a wick filter. Water crawls up the wick and evaporates as the dry air passes over it. The mist types pushes tiny water droplets into the air to float away and dry before they land on something. Because all tap water has mineral content, when the mist dries the minerals are left in the air to settle as dust. You're also breathing in these minerals as well, though the amounts are so small that it is insignificant for most people. However, some people with breathing problems shouldn't use mist units. This includes all smokers, as smoking disables the action of motile cilia in the trachea, which normally sweep mucus and dirt out of the lungs.

No. It puts out water vapor, which is water that has already evaporated. Other types of humidifiers put out water droplet, which may leave a residue when they actually evaporate into water vapor.

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

Yes, it works for that size room and is so quiet that I am unaware of it. I keep it in my living room and have another humidifier in my bedroom. White dust has never been a problem, but it needs to be cleaned regularly with cotton swabs to avoid build up of particles in the water that build up an orangey residue.

I did. However, it destroyed my humidifier. So my recommendation would be to follow the manufacturer's instructions on adding stuff to the water in your humidifier if you can at all.

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.

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.

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

I would say that your unit is defective, yes. I used my humidifier all last winter in my office, and never had this problem.

When the machine worked, yes, it increased the humidity of the entire room.That's how humidifiers work. Of course, you'll always see a concentration of water vapor initially coming out of any humidifier. Then, the water vapor will disperse relatively evenly throughout the room.

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.

Yes - if you have hard water. White dust will come from any ultrasonic humidifier that is used with mineral-laden ("hard") water. The dust is actually the mineral residue from the water, just like the salty coating you would see in the pan if you boiled salt water until it was dry. I have soft water and do not have a problem with white dust. The key issue with white dust is the water, not the humidifier.

My initial reaction would be to say no. It's really about keeping the insides of your humidifier clean and muck-free. It significantly reduced the amount of slime that accumulates in the water laden areas of the machine. It will also extend the practical use of the wick filter, but dust I is a different matter.

There actually is a related filter, or "demineralization cartridge", if you don't want area around the humidifier to show a white mineral residue (or your lungs to accumulate the same if you operate it near your bed). It's designed to screw on in place of the OEM water tank cap, and reminds me of a Brita water filter insert. I found it sold as a "Sunbeam Demineralization Cartridge", model SDC2300-UM. Here's one source: http://www.jardenstore.com/productdetails.aspx?pid=2517

Yes but I think it has more to do with your water source than the humidifier. It did more when I used tap than with distilled.

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.

Don't know. You might check with the humidifier manufacture for restrictions, or if it would void the warranty or damage it.

I agree with L. Honeycutt's answer except that the tank seemed to stay cleaner when we consistently used them. It may also depend on the Ph of the water you are using in the humidifier.
