This humidifier works very well. However, I don't recommend using anything other than distilled water in the unit, as the performance and longevity of the unit will be compromised if you use tap water. The manufacturer supplies the humidifier with a small brush to remove mineral deposits from the metal nebulizer plate, but in my experience, (having owned an older model) once the minerals are stuck to the plate it is pretty much impossible to remove them effectively. I'm only using distilled water in the new model - 1 month of nightly use and it still looks like new.

Pros: The old model gave me many years of reliable service; I expect the new one to perform at least as well. It's quiet on the low setting and hardly takes up any room. The tank usually lasts through the night (on the low setting) and is easy to fill and clean. I love that blue night light!

Cons: The fan on the old model began rattling after a few years, especially when set to 'high' (not a problem when left on the 'low' setting which is perfectly adequate for the size of my room). Occasionally, I have a little difficulty attaching the tank to the base. When the tank is empty, the fan will continue to turn (no auto shut-off).

10 hours of operation on 1 tank? - I don't think so... but if I fill up the tank and turn it on right before I go to sleep, and then shut it off when I wake up, it works very well for me. I highly recommend this ultrasonic humidifier.

We bought this unit for our bedroom because we had used a similar unit before and liked how quiet it was. This unit was quiet, definitely put humidity in the air in our room. The downside however, is that the carpet around the unit was getting wet, so we put a towel underneath, which turned out to be soaked, along with the carpet after running all night. This was unacceptable so we returned the unit.

I bought this humidifier and decided to try it out in my house.. I noticed that like some people said that it shot mist up 6 inches and then got the area aound it wet. It did that at my house, but after looking at the Humidstat (checks the humid levels) my room was at 75% humid.. That is why it got everything wet.. not rocket science.
When i have it at work (which is about 30% humid) it works just like it said it does..

If you notice that moisture is starting to build under the unit... then the humid level in your room is perfect. If you are looking for something that turns on and off to the humid level.. this one is not for you.

ok, first of all i bought this thing because its reviews werent bad at all AT FIRST. I bought this for my mother. Gave it to her. SHe loved the blue light and very quiet. ONLY BAD THING WAS...it quit working within 2 weeks. It runs, light turns on, but no water sprays out. I lost receipt and now a over sized night light on MY dresser. UGH. If anyone knows how to fix this damn thing please let me know.

i liked the first one. this one is quieter and has a higher output. new and improved and i like it.
