Product Description
The Air-O-Swiss Ultrasonic Warm Mist Humidifier uses high-frequency vibration to generate a micro-fine mist. It has a built-in hygrostat and an output regulator button. A replaceable demineralization cartridge ensures a hygienic, pure water mist, without lime scale or mineral residues. When operated with the pre-heating function, the water is heated to 176F before it enters the nebulizer chamber. The mist exits the humidifier at a comfortable 104F, so the mist does not cause room temperature to fall. Pre-heating also keeps the water cleaner. The Air-O-Swiss Ultrasonic Warm Mist Humidifier also features Automatic and Sleep modes. Automatic mode maintains ideal humidity you select in relation to room temperature. When the Sleep mode is set, the unit shuts off after eight hours. Powerful & exchangeable demineralization cartridge prevents white dust Built-in hygrostat for controlled humidification Timer Auto & Sleep modes Output regulator button Multi-function LCD display Powerful & exchangeable demineralization cartridge Quiet operation Easy-to-clean & handle Mains voltage - 120 V/60 Hz Power consumption - 40 W (without preheating), 140 W Room coverage - up to 600 sq. ft.

 Best I've ever used February 1, 2006
181 out of 181 found this review helpful
I got this to humidify my kids room. Previously we had been using the old vick vaporizer but it only put out for about 6 hours and had some other issues with getting the mineral content of the water just right.
Anyway this is without a doubt the best humidfier I've ever used. Setup was a little confusing at first (where little parts went. The tube hole through the tank was a little disconcerting but after I understood its function I saw it wasn't going to slosh water everywhere.
For a humidfier it has a amazing number of options.
Warm Mist vs Cool
I had always used "warm mist" but my wife wanted "cool mist", this was the only one that had both. Warm and cool are relative terms however. When I think of warm mist I think of the Vicks which can scald you if you get to close. It heats the room up in operation. This device the warm mist is sort of warm. It takes a few minutes to warm up and if you put your hand over the output you can feel its warm but not hot. It goes to warm by pre-heating the water before it hits the vaporizer. In cool mist it just vaporizes.
Output-
You have two output controls, relative humidity and mist volume for lack of a better term. Think of it as fan speed (but no fan)You set the humidity and it spits out water as needed. I don't know where the sensor is but the position of the output nozzel can really affect its reading.
The tank seems to hold enough water for 24 hours of output or 2-3 nights of use. The output is plenty adequate for a bedroom.
Controls-
Lots of controls on/off, heat/no heat, humidity, output, timer, auto mode and more. This is the big difference betwen this and the lower end model. Someone finally figured out how to put a timer on a humidifier (imagine that). So it runs as many hours as you set it. The sleep mode sets all settings automatically and runs 8 hours. I love it.
Noise-
What noise, this thing is silent. No bubbling or hissing or fan noises.
Filling the tank-
Take it out, flip it, unscrew the deminerlization cartridage and fill er up. Not the most stable but it works. Carry handle makes it easy to take back.
Its everything you could possibaly want in a humidifier. Low maintence, easy enough to fill, quite, lots of settings for any need.
Beats the heck out of the old vicks and some fan based whicking mold catching filter units I've used. The closet thing I ever had was a drugstore one that spit out the good stuff for 15 minutes and then broke. This is a quality product (and price) and should last (I've had it 2 weeks at the time of writing). It may be expensive but it does what you want and will outlast many of the others. If you've got the money its worth it.

I went to a local Bed Bath and Beyond to find silent or near silent humidifier. Salesman introduced this Air-O-Swiss as the best machine on market. He added Venta-Sonic does the same job but costs $50 less, and all other brands can't compare. I bought both units to compare. Air-O-Swiss is a clear winner, hands down.
The two machines sat side-by-side. It's clear immediately to everyone that Air-O-Swiss is quieter. Even at highest setting, Air-O-Swiss' noise level and frequency are lower than Venta-Sonic's, and they blend nicely into background. They don't give me headaches as Venta-Sonic. At lower settings, Air-O-Swiss can be virtually silent. With Air-O-Swiss on, I slept very well. The next night was Venta night. Unfortunately, the base machine noise was just as bad as the first unit that I returned earlier for noise problems. I tried to go to sleep with it on but after a few hours, headaches and agitation from the noise made me shut it off and switch on Air-O-Swiss and slept through afterwards.
I kept on alternating units days and nights to observe results from continued operation. After three days, Venta-Sonic unit began to add that strange squeeking noise. Air-O-Swiss gave consistent good near silent performance...and going strong still. Just based on noise-level alone, I had to return Venta-Sonic even though Air-O-Swiss costs $50 more. But that extra costs are further justified by the following:
1. Consistent Performance - I can put Air-O-Swiss on automatic mode with preset humidity level before I go to sleep, when I wake up, my bedside humidity reader (far away from the machine) has within 1% margin of error to the preset desired level.
Venta-Sonic however, I can put it to MAX settings, and I get only around 32% sometimes and other times anywhere below 50%.
2. Greater Output Capacity - My bedroom is 300 square feet+, half of 600 both machines claim can cover. Air-O-Swiss comfortably reaches my desired level (b/w 40% and 50%) with lower settings (It can go as high as 75%, I only set it up to 50%). Venta-Sonic labors over 8 hours at MAX settings and gets me LESS humidity! It won't get me above 50%.
3. Ease of Use with Digital Control - I like Air-O-Swiss' Auto Mode with Desired Humidity Setting. The machine adjusts output automatically. Venta-Sonic only has two dials, you'll have to experiment for a while to find the optimal settings. As soon as atmospheric humidity changes, which can be daily or a few hours, you'd have to re-adjust again...that's like shooting darts in the dark all the time, you can get close if lucky but never on target.
4. Better Mist Venting Notch Design - I put both machines on 3-feet-tall dresser. Air-O-Swiss' notch is tilted higher than Venta's. This means when operating cold mist, Air-O-Swiss's disappears into air vs. some Venta's still hit the floor - not enough to form condensation but less efficient in humidifying - perhaps that contributes to Venta's lower output previously mentioned.
5. Better Craftsmanship - Venta-Sonic is a notch below Air-O-Swiss, appears to be made simpler and CHEAPER.
Filter changes and clean up are similar. Venta needs to change filter cup. Air-O-Swiss needs filter cup and once-a-year silver stick change. Both are fool proof. Venta filters are more expensive but Air-O-Swill has extra silver stick. Cost-wise it's similar. I like Air-O-Swiss's option of replacing resins - just dump old resin in filter cup and put new packet in and you get a NEW filter - this cuts cost by almost 65% and less trash for the environment.
Water tank design is similar. Both fills water upside down. I still prefer Air-O-Swiss because the top is more leveled, easier to sit in sink or bath tub than Venta's tilted top. When moving Venta-Sonic, water spilled between base and tank. I had no problem with Air-O-Swiss.
Anything Air-O-Swiss can improve? Sure! The humidity reader on the machine is adjusted about 13% lower than actual average room humidity. They probably did it to ensure average humidity far away from the unit reaches target, but I think they can do so internally without having to show it. It would be a mistake to read the room humidity off that machine.
After I got the machines, I googled on both. There was one review elsewhere saying that Venta-Sonic broke after a month and half, out of store 30-day warranty and owner took a loss. Air-O-Swiss has 3 year warranty, if I remember correctly, Venta 1 year.
The trouble I went through is worth the finding of the right humidifier for me. Hope this helps those with similar concerns!

so far, a wonderful piece of work December 4, 2005

I've had my Air-O-Swiss 7135 for a little over a year now and I think it's absolutely wonderful. It shoots a very fine mist through the tube on top, which you can turn to face whichever direction you like, in a 360-degree plane. (The instructions do tell you that the humidifier should be put on a table, not on the floor.) It also operates very quietly. You don't hear any fan and you only occasionally hear the sound of trickling water. I leave mine set on automatic. Simply select the humidity level you want in your house and this little appliance will turn itself on and off seamlessly to keep the humidity level near what you've selected. I consider the other features secondary to the ease of operation.
My only complaint so far with this item is with filling the reservoir. You have to turn the reservoir upside down to fill it, and it's large enough that holding it under a faucet can be a chore. (I find myself filling the reservoir every 24 to 36 hours.) The only fix I can suggest to the manufacturer is to allow you to pour water into an opening in the top of the reservoir so that you wouldn't have to remove the reservoir to fill it. Still, I love this humidifier.

Initially I was hesistant to write this review, as there are so many incredibly positive ones already, with which I wholeheartedly agree. But, odd though it may seem, this humidifier is so fantastic that I feel it would be wrong not to add my support for it.
I have very dry skin and generally need to keep extremely hydrated to avoid respiratory tract problems connected to dryness, so for me humidity is a significant health issue as well as a question of comfort. When I moved to New Mexico two months ago--in a winter of record dryness, with the need for indoor heating--I thought I was going to shrivel into a spiky dust ball and blow away down the street like a tumbleweed. I don't know if I would have spent this much on a humdifier if I hadn't been in a truly desperate physical state, but I was, and I did. I bought mine at Bed Bath & Beyond, because they would let me return it if I was not satisfied, but that's just not going to happen. I am so glad I didn't waste my time and money, or jeopardize my health, on the cheapie machines I have bought in the past.
On the very first night of using this humidifer, I experienced substantial relief. Another full day and night of use cleared away painful dryness in my throat and nose. A day and night or two more got me back to normal. After that, it was all about the luxury--I am without any respiratory discomfort, and find that my skin is actually benefitting from the extra humidity, remaining soft and moist until morning. And I've even switched to using it at night only! As for sound, quiet is not even the word for it--it is almost calming, since the only sound is the soft press of steam and an occasional gentle gurgling of water. There is a humidistat that lets you set the level of humidity, a steam volume control, warm or cool mist selection, and timer.
This machine is a thing of beauty. It elevates the (rock bottom) levels of humidity in my room with remarkable speed, and maintains the set level very well. The warm mist option is doubly great--the water is heated to higher temperatures in the base, to prevent formation of bacteria, and then cooled to 104 degrees (neither warm or cold to the touch) before evaporation into the room, so there is no need to worry about pets or kids (or me) getting accidentally scalded. The cool option is good if you want to keep the temperature in the room from increasing due to the steam. If all of that is not enough, it has a little red light indicator that comes on about every two weeks to remind you to clean the machine. It cleans easily with water and vinegar, and has a small brush that clips into the reservoir for hard to reach spots.
I've had it now for about six weeks and find it very easy to use and clean. I'm not sure how big a space it would humidify, but it has no problem keeping my bedroom at whatever humidity level I choose. When I use it in my living space, which is very open between individual rooms with higher ceilings, it does not get the humidity level as high, but still comfortable. And again, this is the desert, so it has a lot of moistening to do. I have to refill every night, as the intense dryness here and my need for high humidity uses up about 2/3 of the tank volume in one night, but I imagine that it would last longer in less extreme places. The demineralization cartridge needs to be soaked for 24 hours before first use, and can be replaced entirely, or can be refilled with its resin when necessary, for less cost. I have recommended this to other dessicated desert dwellers, and have heard nothing but praise.
There is no way to overestimate the relief this little wonder has provided me. On giddy days I even go around calling it my best buddy. If you want a serious humdifier that will work like a trooper without causing alot of trouble, one that will make a measurable impact immediately, look no further. (But don't forget to drink lots of water, too.)
