Air-O-Swiss 7142 Dual Mist Humidifier

As one of the digital Air-O-Swiss humidifiers, the 7142 Ultrasonic Digital Warm and Cool Mist Humidifier combines top of the line humidification with the ease of state of the art electronic and automatic controls. Like other Air-O-Swiss digital humidifier models, the 7142 features electronic controls with an LCD screen, yet where this humidifier differs is in the Air-O-Swiss Intelligent Temperature Compensation (ITC).

Just as many modern appliances will function based on their surrounding environment, so too will the Air-O-Swiss 7142. This humidifier will adjust mist output based on the temperature of the room. This works to maintain a comfortable humidity level with little worry or supervision. This automatic functionality is great for asthma and allergy sufferers on the go or anyone who wants a constant relative humidity level without having to spend a lot of time monitoring it. This model also has dual warm mist and cool mist capabilities, so whatever your preference, the Air-O-Swiss 7142 can meet your needs.

  Get the steam one
Reviewed by: dust hater from Ohio

I couldn't make up my mind and have a good size house to cover so I bought both this one and the S450 steam unit. I put the 450 in the bedroom and this in the front room. I can't use tap water as I HATE the white dust & don't use the hydrocell as I noticed a funky smell when I started using it. I now use RO water thank goodness we have big tanks, no demineralization cartridge & no hydrocell. Now I have no dust & no funny smell. I do have to wash the unit out a little bit more but can handle that over the dust. Only took the humidity up from 25 to 33 over a months time but it is a much bigger area than recommended for.
  Work great
Reviewed by:  from 

I had my Air O Swiss 7142 for 3 years. It works great not only does it help the air in the house but also keeps my hibucus blooming during the winter. I can see a big difference in my allegy since I started using this.

Customer Q & A

Q1: What is the difference between Ai o Swiss 7142 and 7144 models?
A: Look, tank capacity, and coverage. The 7142 has a larger tank and holds 2 gallons of water vs. just 1.5 for the 7144. While both put out about the same amount of moisture over a 24 hr period, the 7142 requires fewer refills and covers a larger area more square feet than the 7144. The 7142 is taller and has chrome accents while the 7144 is shorter and favors more a matte finish/look. Other than that, they're nearly the same. Same features, same accessories, same price, etc.

Q2: Can i use this for a little wine room cellar to humidify the cellar and my cigars?

A: Yes. I'm not sure what humidity level you need to maintain, but this should help to keep it to whatever you set it to between 40 and 75%. Like other humidifiers, just make sure to replace the cartridge and clean the unit regularly, and it should provide you years of reliable service.

Q3: Is this product easy to work and keep clean. thank you

A: Yes, pretty to work. You'll fill, then replace the tank. plug it in, then set your desired humidity level and output. The key with this humidifier, in terms of keeping it clean, is the same with other ultrasonic models. It needs to be done regularly, particularly depending on the hardness of your water. You can use EZCal or a home mixture of white vinegar to remove scale, but cleaning is fairly simply. You'll want to rinse or wipe the interior of the tank if you can get your hand inside and rinse the nebulizer compartment area where the water is actually turned into mist. The two areas to focus on in the nebulizer compartment are the float and diaphragm. Nearly all ultrasonic humidifiers, including the 7142 come with a small brush. If you lose it, an old toothbrush will work just as well. You'll use that to remove any scale or buildup around the diaphragm looks almost like a small brass coin and around the white float scale buildup around the float can cause it not to move up and down correctly and make your humidifier think it's out of water when it's not. Keep up with your replaceable parts, particularly the demineralization cartridge and that's about it. Most people who do experience problems aren't cleaning the humidifier often enough or aren't replacing the cartridge soon enough. Hope that helps!

Air O Swiss 7142 Ultrasonic Humidifier Reviews
Air-O-Swiss 7142 Digital Humidifier

The Air-O-Swiss 7142 Ultrasonic humidifier is the best of the best of Air-O-Swiss humidifiers. From output to features, the 7142 is a durable humidifier more than capable of providing relief from dry air anywhere in your home. With full electronic controls and ITC, this ultrasonic humidifier makes it easy to keep the air in your home at a comfortable relative humidity level.

What I like about the Air-O-Swiss 7142 Humidifier

Easily, the best features of the Air-O-Swiss 7142 are the full electronic controls. With a digital LCD display, setting this humidifier is hassle free. From the control panel you can turn the unit on/off, select a humidity level and mist output, set the timer, choose between warm mist and room temperature mist, set sleep or auto modes, and determine when the tank is empty as well as when the humidifier needs to be cleaned.

Tank capacity is another area where the 7142 excels. You can put a full 2 gallons of water in the tank, instead of 1.5 or 1.75 gal. This doesn't seem like a whole lot more, but you'll notice the difference in how often you have to fill this model vs. other ultrasonic humidifiers. Filling an ultrasonic is never as easy as a top-fill evaporative models, so anything that reduces the number of times you have to fill your humidifier is a big plus.

Quiet operation is also another hallmark of this model. It's quiet enough that it won't disturb light sleepers, and even when your home is completely silent the most you hear is a low hum and the occasional gurgle of water.

Air-O-Swiss has done a great deal over the years to improve hygiene. From a Hydro Cell that uses activated carbon to adsorb impurities and a demineralization cartridge to remove hard water minerals to ionic silver embedded in the demineralization cartridge shell and preheating the water to destroy microbes, the AOS 7142 has an array of features to keep the water as clean as possible. This not reduces the chance of putting things you don't want back into the air but also works to extend the life of the humidifier.

Lastly, and certainly not least, the output of this unit is higher than most other Air-O-Swiss humidifiers. While the majority of ultrasonic humidifiers humidify approximately 600 sq. ft., the 7142 Ultrasonic will cover up to 860 sq. ft. Again, these humidifiers are most effective with open floor plans and large rooms with good air circulation. While I never take manufacturer stated coverage at face value, this model is certainly better than average.

What I do not like about the Air-O-Swiss 7142 Humidifier

Once you know the controls, using this humidifier can be a cinch. Getting familiar with them... is another story. Luckily the user manual gives you a simple break down of all of the features and buttons, so in no time at all, you can be enjoying the benefits of a fully digital humidifier.

This unit is a little larger than other Air-O-Swiss humidifiers (mainly taller), so make sure you provide yourself with stable base to place this unit.

Overall, the Air-O-Swiss 7142 is a great fit for nearly any home, and the style/design gives this home appliance a stylish and sleek appearance. It is versatile and provides a wide range of levels and features that make it a great in most homes where dry indoor air is causing problems. The larger tank cuts down on refill frequency, and the output is strong enough to bring even the driest space back to being comfortable.

Why buy from Customer Testimonials
My son has always had a nagging cough when the weather gets colder, that persists all winter long. The Vornado Humidifier  seems to have helped him feel better, and I don't hear nearly as many late night coughing fits. Thanks!
