Air-O-Swiss Ultrasonic Humidifier Review

Air-O-Swiss Ultrasonic HumidifierIf you are in the market for a high quality premium humidifier that is designed to last many years then you will find a few available on the market. One such popular choice is the Air-O-Swiss 7147 Ultrasonic Humidifier. With a retail price of  just under $200 this is a humidifier designed to work hard and provide many years of use. So is it worth spending so much on this product? Let’s find out below.

Product Features:
First up let’s begin by taking a look at the design of the unit. The entire base of the unit is a sleek black color, including the nozzle at the top. The lcd screen is in the middle of the base, with 3 buttons either side of it to control the operation of the machine. The lcd displays the basic info and settings that are currently selected, and shows you the current humidity level of the room. The buttons are all surface touch buttons which are responsive and easy to operate. There are two nozzles at the top of the machine and they can both be rotated and put in whatever direction you desire. One can face forward while the other faces backwards for example, and this provides a good means to ensure even mist distribution. Overall the design of the machine is very modern and sleek, and it certainly looks a lot more modern and advanced than many of the cheaper models available on the market!

This is a combination humidifier meaning you can use it to create cool or warm mist. This is a great feature although we should mention that the warm mist is not quite as hot as the mist that comes out of a vaporizer. However the water is heated enough to ensure that the mist doesn’t cool down the room temperature too much in winter time. The built in timer can be set to run between 1 – 8 hours, or you can set the machine to run constantly. There are a variety of other settings to play around with. You can set the mist output manually if you want – this can be set to low, medium or high. Otherwise you can leave it set on auto mode. This will analyze the current temperature and humidity of the room and set the output to the ideal temperature. You can even set your desired humidity level if you want, so as you can see there are a few different options to consider. There is also sleep mode which aims to create a comfortable sleeping environment. This model can humidify rooms up to 600 square feet which is quite a bit more than some of the cheaper alternatives.

This unit has a filter which may need to be replaced every few months depending on how you choose to use the machine. If you plan to use distilled water then there is no real need to worry about replacing this. If you stick to normal tap water then you will probably look at replacing this a few times a year. Also included with this machine are demineralization cartridges which are needed if your area has hard water. These also need to be replaced every two months ago, but again you won’t need to worry if you have soft water.
One downside to this machine is that filling it is a little awkward. Like most humidifiers it needs to be flipped upside down in order to be filled, however the base of the unit sits in a pool of water so when you remove the tank it can create a bit of a mess if you aren’t too careful. Once you get the hang of it it shouldn’t be a problem, but we can’t help but feel that Air-O-Swiss could have made a slightly less hassle free design! Once the tank has been filled then the unit works very well. The high setting creates a big flow of steam which will leave the surrounding area damp if left for a few hours. Auto mode seems to create a good compromise, and we had the best results using it this way. The tank has a capacity of just over a gallon, so you are looking at a running time of around 16 hours on the medium setting for example.
So that is a rough summary of what you can expect from the Air-O-Swiss Ultrasonic humidifier. It does have quite a big price tag, but this is what you should expect to pay if you are looking for an advanced long lasting humidifier. It comes standard with a one year warranty.



  • Lovely modern design
  • Warm and cool mist
  • Rotating nozzles
  • Many settings to pick from
  • Can humidify large areas


  • Pricey
  • Little awkward to fill

Summary: .With a price tag of almost $200 this is quite a pricey machine, however it does come with a variety of great features which somewhat justifies the price. If you are looking for a quality humidifier then this one is certainly worth a look. You can check the current pricing and read some user reviews over on the Amazon product page.
