Wonderful so far, this little humidifier really puts out the humidity for a large bedroom--and that's on the lower setting! One filling on low can last you two nights. No filters, so like other ultrasonics, it may put out some white dust. Regardless, I couldn't be happier with my purchase. I'm breathing so much easier, and there's not a lot of upkeep required. Highly recommended.

It is quiet running, you can adjust the moisture. Runs a good 24 hours on second cycle before I have to refill.
At the end of the season I just dry out throughly and put a little vaseline around the opening before storage.

1. Because the humidity is not distributed upwards, but at an angle instead, it sprays the raised silver top of the tank with moisture which then needs to be cleaned up. Might as well be leaking from the tank, what a pain.
2. This unit also has an inaccurate humidity sensor. Because it humidifies the air directly around the unit, a room with 30% humidity is suddenly detected as 60% humidity after the unit runs for a short time, causing the unit to prematurely switch off. You'll have to override this by setting it at "always on", but the sensor still displays the inaccurate reading which is therefore a reminder every time you look at the unit of how it's not functioning as designed.
3. Because the tank is so opaque from dark tint, it's very hard to see the water level and how much is left.
4. The tank doesn't hold as much water as other units on the market, and the handle placement makes it awkward to hold while filling.
I previously owned the Holmes ultrasonic model, which was a great unit except that it was a pain to clean. I figured this Bionaire unit, which was $20 more and looked cool, would be easier to clean. After opening it up, it looked more difficult to clean. Returning this to Target and going with the Holmes.
Honest reviews on Bionaire BUL7933-UM Ultrasonic Tower Humidifier
We have had a number of humidifiers in our home to try and combat the dry air. We live in Wisconsin so the air gets pretty dry in the winter from the furnace running all of the time. After some bad luck with units purchases at the local hardware store, I decided to buy one online.
After reading some of the other reviews, I was a little hesitant to purchase this unit (in regards to leaking and humidifier monitor issues). However, after we got this unit and started using it, we absolutely LOVE it! We have not experienced any of the issues that the other reviews mentioned. The humidity monitor works great, and is a very nice feature. Although we have a ceiling fan running all the time so that probably helps circulate the humidity around the room. Our last unit actually did leak right out of the box, but this one is perfectly clean.
The digital screen is a very nice feature. The buttons are intuitive and I was able to figure out all of the controls within a few seconds. Many of the humidifiers available look somewhat "medical", which is not appealing when it's going to be sitting in my living room. This thing is even more stylish than it looks in the picture. It even has button to turn the digital screen off, in case you have it in your bedroom and don't want the extra light.
The spout works great, and the water compartment is easily removed for fillup. It's very quiet, so won't keep you awake at night either.
If there was a negative, it might be that the water output is not that high, but I don't think ultrasonic units have as much output as heating units. Everything else has far exceeded my expectations. I highly recommend it.

Decided to try an ultrasonic dehumidifier as house was very dry. Unit is easy to set up, and is putting about 1 gal/day into the air (room humidity has increased although not as much as I would have liked). I found that neither the instruction manual nor the unit itself seem to have an identifiable model number. I also found that although the manual discusses a demineralization filter, it seems to be a discontinued item (at least it is not stocked by Amazon).
