This Air-O-Swiss ultrasonic humidifier uses high-frequency vibrations to turn the water
into a micro-fine mist that creates a comfortable environment in any room. This model provides you a dual option with a
water pre-heating function, when the mist exits the Air-O-Swiss 7135 at a pleasant 104 degrees, as well as a cool mist option
where the water exits at ambient temperatures. Intelligent Temperature technology monitors the temperature and
automatically adjusts the output when conditions change. These features give this ultrasonic humidifier a range of capabilities
that make it truly unique.
The Air-O-Swiss 7135 and 7133 are virtually identical models. From features to product specifications, these two humidifiers
largely mirror each other. The only real difference between these two models, aside from price, is the controls of each.
With the 7135 Ultrasonic the controls are electronic with a digital readout. With the 7133 Ultrasonic the controls are manual and
adjusted with the use of two knobs. With the digital controls of the AOS 7135 you have an timer and sleep mode feature that the
AOS 7133 lacks. Aside from controls and price, these two humidifiers are identical in performance and capability.
What I like about the Air-O-Swiss 7135 Ultrasonic Humidifier
The versatility of this unit makes it one of the best humidifiers available today. Though I generally do not suffer
from sinus problems or dryness year round, the warm or cool mist options are great for any time of year. The capacity is large
enough that I'm not constantly refilling it while I use it, and the weight and size make it ideal for any room in a house or
apartment. The timer mode is an excellent additional feature, and I generally set it to run for the full nine hours before I
go to sleep at night. That means that I don't have to worry about shutting it off in the mornings.
I tested this humidifier in my apartment. The air in my
apartment is very dry which it makes it difficult to get a good
night's sleep. During the winter months, I almost always wake up
with my eyes stinging or with a nose and throat that feels like it's been through a blast furnace. I usually do not like to use
a humidifier in my bedroom, because I am a very light sleeper, but the AOS 7135 was surprisingly quiet. The near silent
operation of the fan did not keep me from falling asleep.
Air-O-Swiss set itself apart from other brands with the combination of three key features: the Ionic Silver Stick, the Ultrasonic Technology,
and the Demineralization Cartridge. The Silver Stick uses silver ions to keep the 7135's water tank free of bacteria and other microbes.
The Ultrasonic Technology furthers this in that the ultrasonic vibrations work to not only turn the water to mist but also break
apart some microbes. Lastly, the demineralization cartridge acts as a filter to prevent any mineral content found in your water from
being dispersed into the air. This cartridge also helps keep the tank free of mineral build up that is often found in regular humidifier
use.
What I do not like about the Air-O-Swiss 7135 Ultrasonic Humidifier
There is not much to dislike about this humidifier. It is one of our best sellers and I did not have any problems
with it during our product testing. If I had to choose one downside to this model, it would be that you have a cartridge to
replace every three months and an Ionic Silver Stick to replace each year. Be it that these two features help keep the
Air-O-Swiss Ultrasonic running smoothly and free of bacteria and viruses, the cost to replace these is relatively minor.
In summary, the Air-O-Swiss 7135 combines simple operation with minimal energy
use and unmatched versatility. The improved system helps keep the tank water clean, hygienic and minimizes fine dust
that is sometimes left by other brands of
ultrasonic humidifiers. The AOS 7135 is near silent, and its sleek design
minimizes its footprint in your bedroom or living area.
