After a little search over the internet my tryst ended with Air – O -Swiss AOS 7147 Ultrasonic Humidifier with both warm and cool mist features. It uses the AIR-O-SWISS ITC technology (Intelligent Temperature Compensation) which automatically regulates the output to create an appropriate level of relative humidity in accordance with the room temperature.

  • Dual Mist option to choose from warm or cool.
  • Digital surface touch display. (I’d say the best)
  • Capability to humidify the air in a room of 600 sq. foot
  • Noise free performance. (Big relief as the most common humidifiers are clattering boxes)
  • Sleep mode which automatically sets the humidity level in the night.
  • Timer feature with which we can set the working time of the humidifier. (1-8 hours or continuous)

Accessories – It  has some included accessories that come with the product

  • Demineralization Cartridge which prevents the release of any harmful minerals in the air.

I am impressed with the design of this humidifier as it has a very uber looking front panel with very friendly touch interface that anyone can use without a hassle. The finishing of the device especially on the edges is a work of quality. Overall the device has a black glossy color scheme which is very soothing to the eyes.  The humidifier  looks like a polished furniture with its own class & finesse.


Now, let’s discuss about the real performance part. Since, I have used it from over a fortnight, I think I qualify to comment about its functioning.

After 14 days of use, I haven’t encountered any sort of problems yet. The product has been performing brilliantly and way above my expectations. Moreover, I didn’t expect it to be this good because my previous experience with a humidifier was not so pleasant.


Ease of Use

Being an ever busy guy who is always occupied by work, I am not much comfortable with the idea of using manual settings. I always search for devices & peripherals that have the option to work on their own i.e. automation. And this device is made for guys like me. As I found a great relief by using its auto settings option on the front panel,  the humidifier adapts itself to the surroundings very well & I didn’t need to manually check it.

Humidity levels work perfect on the automatic setting. The timer function is great because you just have to set the time you need it to run, 1-8 hours or the continuous mode where the humidifier keeps running until it runs out of power!

All the features mentioned in the product description proved to be novel. The device works noise free, hassle free and labor free.

After Sale Service – The after sale support of the device is also superb, the installation guy gave me a good demonstration about the product’s features. Though, it was never a rocket science! I’d say.


I would say I am intensely satisfied with the product. As I mentioned before, my previous experience with other personal humidifiers was that some were clumsy and not much graceful and I was always skeptical about their reliability and durability but Air-O-Swiss AOS 7147 Ultrasonic Humidifier has changed my whole perception.

Though I have been using it only from the last 14 days and it might be only the tip of an iceberg. But I’d say it’s been so far so good for me. It’s noise free, automated working  and its congenial design has really flattered me. I’d recommend it to anyone planning to buy a humidifier. This product delivers more than its price value.
