I had been pricing and comparing the substantial number of humidifiers on the market and I am glad I settled on the Air-O-Swiss. Despite its higher price, I am quite satisfied with its functions, control, design and specifically, its quiet operation. I was looking to pay between $70-150 for a quiet, low-maintenance model to add humidity to my [very dry] 10x12' bedroom. I purchased it at a local store for the same price as listed on Amazon; I am glad I was able to see [and hear] this model in operation.
There is NO sound, even at the highest setting. I'm a light sleeper and cannot fathom a bedroom appliance that even approaches a dull hum.
The visible mist generated by this model is pleasant for me and my pets.
I have been refilling each morning, as I have had the device on a high setting and running nonstop.The compartment becomes about half-empty after a full day at this setting. Refilling is a snap.
The ability to have cool and warm settings is a big plus, since the jury is still out regarding the negatives and rewards of either mode.
The system has been running clean and I am certain this will continue to be the case with a modicum of effort. The cost of the filter and the silver stick is not intimidating and the recommended three-week maintenance check is reasonable.
The design is quite fetching. Minimalist and fetching.
I have it sitting on the floor and there is no dampness on the carpet as mentioned by owners of other brands. This tells me that this model is doing a good job of propelling the mist into the air.
My roommate recently paid $29 for a smaller Holmes humidifier. The Holmes is downright deafening and I am sure she would have paid the difference for an Air-O-Swiss. Silent operation is really important.
The only possible shortcoming is the hygrometer. It is not entirely intuitive: the machine is to shut off after the desired humidity percentage is met, yet I have yet to see the model shut itself off. Turning it off manually is not a big deal.
I took a big step purchasing an air purifier, but this purchase has made a significant difference in my bedtime and bedroom comfort. I've had some winter nights with seriously labored [allergy, smoke and pet-related] breathing but I find this device has given me a little peace of mind and tangible change.
With not having much experience with buying humidifiers, I purchased this one based on some online research and with the help of user reviews. I was very worried about the noise factor that comes with having a cool mist humidifier but this one passes with flying colors. I'm a very light sleeper and require almost total silence in order to fall asleep. I can't even tell that this machine is in the same room! I love the fact that it can be switched from cool to warm mist at the press of a button and that I can control the amount of mist and how fast or slow it comes out. The only downfall that I've experienced is how difficult it is to keep clean. The still water that sits in the unit's base will have a black build up. This same build up is located at the base of the blue, water-holding section, as well as the tube and attachment the mist comes out of. The machine comes with a small brush, which does not do the job. By running pressurized water over the build up and using a long tubular bristle brush I can get the unit semi-clean. If any one has a better method, please let me know.

This product has a fatal flaw it has a mechanical hygrostat to control humidity. It's basically a spring loaded device. It doesn't work reliably. You set the humidity level one day, but as the spring adjusts to its own tension, its humidity control stops being accurate.
I had to return my unit 3 times. Each time they replaced the return with a brand new unit. But each one eventually manifested the same problem. *It is a design defect.* Fortunately, the device has a three-year warranty. If you are the type of person who demands that their purchased products work as expected, you will need this warranty. I had to return my unit at the end of every season.
Unfortunately, the company threatened to stop honoring the warranty because I had returned the unit so many times. Rather than send me a unit which would work reliably, they took the tact of blaming me for returning the defective units. They never claimed that the units that I returned were working at spec.
You may not notice the problem if you have the unit in a large room, but in my case it was used in a small, approx 8' x 12' room with a closed door. At the lowest humidity level setting, the room would eventually get very humid, the level couldn't get dialed down, and I had little control over the level of humidity. Because the unit doesn't have a digital readout of the humidity level, most people wouldn't notice this. But I checked the level against a stand-alone humidistat.
If the hygrostat worked, I'd give the unit 4 stars it's otherwise a fine device. I'd echo the sentiment about the tank. I think someone in Marketing told the engineers to design the tank with a visually appealing rounded top. But it's a pain to refill. You have to always hold onto it while filling it. It will not stand up on it's own. It is cumbersome to refill and will fall over if you let go of it. It's always a two-handed operation to fill.
My advice would be to try one of their units with a digital humidity level readout. I haven't tried them myself, but I'm guessing that the hygrostat on those models will be more accurate and thus, useful.

I am very happy with this purchase. I can't imagine another unit outperforming this one.
Pros:
1)High design; the prettiest, sleekest humidifier you'll find. Everyone who sees it compliments me on it and it's become a very popular acquisition.
2)High output: produces a thick, steady stream of humidity. When on highest setting, outpaces volume of other cheaper units.
3)Great customer service: I had a hairline fracture in the water tank and the Air-O-Swiss folks replaced it within days; it was very fast service and completely hassle free.
Cons:
1)After 2 weeks, I discovered a fracture in the water tank causing water to leak out onto the table.
2)No hygrometer/hygrostat display so there's no way to know for sure what degree of dryness you need to compensate for.
3)Water tank is a little on the small side and needs to be refilled often Very often if highest volume setting is used.

This humidifier is fantastic but I cannot get rid of the white dust. Despite the fact I'm replacing the desmineralization cartridge regularly, this humidifier is producing a lot of white dust.

I was referred to Boveda by a trusted cigar enthusiast who swore by them. I was excited to try them out in my three rack home humidor. After being patient for several days the humidity level dropped significantly, however on the positive has held steady, just not at the expected range based on the product specs. I enjoy the premise of the product however it just isnt for me and my cabinet. I may not purchase these again unless someone can prove me its a worthy year round investment.
