Air-O-Swiss is a fairly well-known brand in the air purifier market. PLASTON International (based in Switzerland) is the corporation that manufacturers Air-O-Swiss products for distribution in North America. Besides making one of the best humidifiers on the market, Air-O-Swiss is also considered one of the most eco-friendly machines as well.

As per their website, the newer line of Digital Ultrasonic Air-O-Swiss humidifiers have been upgraded to help set a new standard in home humidification. In my opinion, this is one of the more advanced units on the market and could also be one of the most durable as well.

What is it?

The Air-O-Swiss AOS 7135 is a warm and cool mist digital humidifier. This means that you can choose to have warm mist fill your room or cool mist, depending on your preference. This machine is capable of humidifying air in rooms up to 650 ft.² and also has a pretty unique control panel and LCD display for adjusting it’s different settings.

Besides its auto-shut off feature, the Air-O-Swiss also comes with some pretty interesting functions such as; a timer option which you can program to run continuously for anywhere between 1 to 9 hours. It’s (ITC) or Intelligent Temperature Compensation technology, which adjusts the output temperature of your mist in accordance to the humidity and temperature of your room. Or you can use it in sleep mode which works to pre-determine a comfortable level of humidity throughout the night.

Lastly, this machine comes with “tri-band microbial protection“, which uses their Ionic Silver Stick, Pre-heating, and their Ultrasonic system to help keep your water clean and prevent any bacterial growth.

What I liked?

What I liked most about the Air-O-Swiss AOS 7135 Humidifier was how good it was able to stop my nose and throat from drying out, especially overnight. It’s ITC also did a great job maintaining the humidity against the temperature in my room. That and the fact that it makes very little noise really helped improve the overall quality of my sleep.

Another thing that I liked about this machine was that there were no leaks and I never experienced any dry white calcium powder build up. As long as you don’t have hard water in your water system and as long as you regularly change your demineralization cartridge, you should never have this problem.

Finally, I really liked being able to choose between a warm mist and a cool mist. I generally choose a warm mist, but occasionally like to choose a cool mist from time to time.

What I didn’t Like?

The one thing I didn’t like about this unit was the cost for cleaning and maintenance. I must admit that the cleaner required is a little pricey, especially if you tend to use your machine for more than 8 hours a day and are forced to clean it regularly.

Overall Opinion

If you have a hard time with allergies or easily experience a dry nose or dry throat in the winter then I would highly recommend trying out this system. The Air-O-Swiss AOS 7135 is one of the best and most durable humidifiers on the market, and that’s why it’s one of the most sought-after machines by allergy sufferers.
