I went looking for an affordable ultrasonic humidifier because I was tired of noisy fans and the other problems associated with evaporative machines. After a lot of research, I decided to try this one, partly because of its simplicity and partly because of pricing (i.e. not a disaster if it didn't work out). I was a little dubious about the small reservoir size, but it's not a problem at all. To keep a rather large room at ca. 35% in the dead of winter in MN (very dry subzero weather), one fill will last a bit over 24 hours, and of course longer than that in less extreme conditions. It's perfectly simple to fill and clean, and wonderfully quiet--just a steady hum that I barely notice, with occasional little glurps.
So far I've only seen a little white dust on the device itself, but not on nearby surfaces. The vapor seems to circulate best (i.e. up and out into the room) when it's placed well off the floor. On a 30" shelf, the vapor tended to flow downward, so I used a milk crate to raise it up a bit more, and that solved the problem. The only issue I've had with it so far was a fairly strong plastic/chemical smell at the beginning, but that's been diminishing with use. It's a great improvement over any of my previous humidifiers.

This is an excellent product. We own three and have used them for two years now. We even take one with us when we travel. Some of the common problems people have mentioned with this humidifier are easily solved if the unit is used correctly. For problems with the unit running for hours without the water level dropping, you have not properly seated the tank on the base. You need to be sure the white valve inside the tank pops up when the tank is placed on the base. If it is not properly seated the water will not enter the base, thus no mist.

Next, for problems with the mist sinking to the ground, we had this problem before I realized what was happening. I had one unit placed on a thin fabric placemat thinking to protect the wooden nightstand. This only caused a problem. The unit needs to be placed on a completely flat, solid surface, not fabric of any kind. Try it - place the unit on a fabric surface and watch the mist fall. Then place it on a solid surface and the mist rises beautifully. I was making a problem where there wasn't one. Without the fabric the unit performed beautifully and the mist has never damaged the beautiful cherrywood surface. With the fabric underneath, the mist sunk and soaked said fabric, causing problems unnecessarily.

Lastly, as to the comments about unit running, all put together properly, but no mist, we also had that issue. This was due to the base of the unit getting overfilled. Not sure how we managed that, because if you seat the tank on the base properly, only the right amount of water passes through. Easily solved, however. I dumped the water from the base, and put the filled tank back on and voila! Misting perfectly again.

This product is super easy to fill, inexpensive, requires no filters, and works GREAT.

I like to make it short
Pro
1) Quiet
2) put out just right amount of mist for my 20 x 16' bedroom
3) Cheap and good looking design
4) Filter-less - save money on filter

Con
1) White dust build up if using tap water - 2 days of using it
2) Expensive if using distilled water as recommended by manufacturer- $1/day - I used distilled water for 3 days and it is free of white dust

I ended up using filtered water after 5th day instead for cost saving, but I have to let it stand for 24 hours before I fill the tank up just to let the fluorine getting out. This works best me.
No more white dust, no more frequent trip to grocery store for distilled water, and best of it, no filter replacement but just my drinking water filter only

I have been using this humidifier for several nights. It is so quiet that you barely know it is on. The mist is very fine and gentle. I have had no problem with leaking or condensation. I have always used distilled water in my humidifiers because we have very hard water in our area. So, I really have no need for an expensive filter. It is super easy to fill and use. Plus, it has the added bonus of being really cute! I also just ordered the pig shaped version for another room. SPT SU-3751 Ultrasonic Pig-Shaped Humidifier

I was looking for a very quiet humidifier for a bedroom. I had purchased a different brand (Hunter) humidifier because the box says that it is supposed to be "ultra-quiet." It has a much more forceful motor and puts out quite a bit of vapor, which may be useful in certain circumstances. But it sounds like a big truck motor compared to the quiet little penguin.

This humidifier came highly recommended from my mother, who bought one for sinus issues. I wanted to get one for the same reason, and because we have a wood stove, combined with forced hot air heat, all which can be incredibly drying.

My critieria was simple: no filter to deal with (been there, done that!) and no wet residue left behind. This fits the bill - the mist is cool and strong and it doesn't leave any wetness on your walls, floors, anywhere!

UPDATE- used to love it, stopped working. Guess things only last a few years now.
