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° F, 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. As the longest running and best selling ultrasonic humidifier made by Air-O-Swiss, the AOS 7135 has proven to
be a reliable way to improve indoor comfort and humidify during the dry fall and winter months. Here is how this mainstay compares to
What I like about the Air-O-Swiss 7135 Humidifier
The versatility of this unit has consistently made it one of the best humidifiers available. Even if you 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 most people will fill it once per day (twice for more severe dry conditions), and the weight & size make it ideal for any room in a house or
apartment. The timer mode can be a great additional feature. Set it to run for the full nine hours before you
go to sleep at night, and you can spend the evening sleeping in comfort while not having to worry about turning the unit off in the morning.
The digital conveniences and features of this model make it ideal for setting up things just the way you want them. The AIROSWISS 7135 humidifier allows
you to choose from warm mist or cool mist. While the warm mist feature isn't hot, it preheats the water just enough that when it comes out of the humidifier, it
has been warmed enough that it won't impact the overall room temperature. It also lets you know, via indicator lights, when it needs to be cleaned (descaled) or
refilled. The LCD displays provides a real-time, relative humidity reading, and an auto (ITC) and sleep features allow you to set it and forget it
for nearly any situation. So you have as much or as little control as you want, and best of all, each feature adds actual value to the humidifier and
only enhances its benefits.
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, it's not uncommon to wake up with a nose and throat that feels like it's been through a blast furnace. Dry sinuses in
the morning or a persistant cough at night can all be symptoms of irritation caused by dry air. For those who heat their home with wood or coal, dry indoor
air can be particularly severe. Regardless of your specific situation, the 7135 can help.
Because I am a very light sleep, I usually do not like to use
a humidifier in my bedroom, but the 7135 dual mist humidifier is surprisingly quiet. The near silent
operation of the fan did not keep me from falling asleep, so aside from a low hum and occasional gurgle of water, this ultrasonic humidifier is extremely quiet.
In terms of hygiene, Air-O-Swiss 7135 humidifier set itself apart from other brands with the combination of three key features: the Hydro Cell, the Ultrasonic Technology,
and the Demineralization Cartridge. The demineralization cartridge acts as a filter to prevent any mineral content found in your water from
being dispersed into the air. The case of this cartridge is also treated with ionic silver, a natural antimicrobial agent that helps to neutralize
microbes and germs. This cartridge also helps keep the tank free of mineral build up that is often found in regular humidifier
use. The Hydro Cell is the newest hygiene feature. This small disc contains activated carbon that filters out impurities from the water before they are dispersed
throughout your home. Lastly, is the ultrasonic vibrations. The very nature of this technology disrupts the cell walls of any remaining microbes, often killing them
instantly. These features all come together to stamp out problems before they start and help to extend the life of this humidifier.
What I do not like about the Air-O-Swiss 7135 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 (or less) and a Hydro Cell more frequently. Be it that these two features help keep the
Air-O-Swiss 7135 ultrasonic running smoothly and free of bacteria and viruses, the cost to replace these is relatively minor.
In summary, the Air-O-Swiss 7135 humidifier 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 nearly silent, and its sleek design
minimizes its footprint in your bedroom or living area.
