  • Product Overview

    Stay cozy and comfortable this winter or any time of year using the Air-O-Swiss U650 Ultrasonic Humidifier. This 3.5-gallon ultrasonic humidifier features warm and cool mist operation, a digital control panel with built-in hygrometer, automatic humidity control, variable speeds, and large area coverage of up to 650 square feet. Using ultrasonic technology, the Air-O-Swiss AOS U650 Humidifier performs ultra-quiet humidification for soothing comfort and undisturbed operation in your space.

    Comfortable Warm or Cool Mist Humidification

    Count on Air-O-Swiss U650 Ultrasonic Warm & Cool Mist Humidifiers to provide comfortable humidified air in any room of your home during the dry winter months. A lack of moisture in the air can irritate your allergy and asthma conditions and cause chapped lips, red eyes, and itchy skin. Additionally, dry winter air can damage your home furnishings, valuables, and interior infrastructure. The Air-O-Swiss AOS U650 Digital Warm & Cool Mist Ultrasonic Humidifier reverses the effects of cold wintry air using ordinary tap water.

    This tabletop humidifier offers a choice of warm or cool mist operation to suit your preference. To operate as a cool mist humidifier, fill the water tank with clean, cold water while the humidifier is unplugged. After turning on, water passes down through the base of the humidifier and flows through the demineralization cartridge. After mineral deposits are removed, the water is transformed into a micro-fine mist and is distributed throughout your space.

    When used as a warm mist humidifier, the Air-O-Swiss AOS U650 Humidifier uses a pre-heating function to heat the water before it is released as a soothing warm mist at 104 degrees F. Warm mist operation ensures that your heated room temperature does not drop significantly when the humidifier operates. Pre-heating also helps improve water quality maintenance.

    Hassle-Free Automatic Operation

    Unlike conventional portable humidifiers, Air-O-Swiss U650 Digital Ultrasonic Warm & Cool Mist Humidifiers boast a variety of automated features to help simplify operation and make it hassle-free. These features include:

    • Intelligent Temperature Compensation (ITC) – Using the built-in hygrostat, set your desired humidity from 30% to 80%. The humidifier will use ITC technology to automatically regulate mist output to maintain your selected humidity level.
    • Programmable Timer – Save energy and conveniently program operation for up to 8 hours using the onboard programmable timer.
    • Sleep Mode – Stay comfortable while you sleep when operating the Air-O-Swiss U650 in Sleep Mode. When using this mode, the humidifier automatically switches to warm mist operation and maintains a humidity level of between 50 to 65%. Mist output is regulated depending on your ambient conditions. Control panel brightness is also dimmed.
    • Water Refill Indicator – This red indicator icon automatically illuminates when it's time to refill the humidifier. You can also easily keep an eye on the water level with the transparent tank.
    • Clean Indicator – A special clean indicator illuminates to let you know that it's time to clean the humidifier. For your convenience, this indicator activates every two weeks.

    Additional Features

    The Air-O-Swiss AOS U650 Warm and Cool Mist Humidifier includes a number of additional upgraded features to help simplify operation.

    • Electronic Pushbutton Controls – Choose your settings precisely and accurately with the electronic pushbutton controls.  
    • Mist Output Regulation – Use the Mist Output button to choose low, medium, or high mist operation.
    • Continuous Operation – Along with automatic operation, you can operate the Air-O-Swiss AOS U650 Humidifier continuously to meet the needs of your environment.
    • Hydro Stick – Treated with an antimicrobial coating, the Air-O-Swiss Hydro Stick helps curb mold and mildew growth inside the humidifier and ensures fresh humidification performance in between recommended cleanings.
    • Demineralization Cartridge – The included demineralization cartridge removes mineral deposits from hard water that could lead to unhealthy white dust. The cartridge lasts up to 3 months and can be replaced with a new Air-O-Swiss Replacement Demineralization Cartridge or refilled with Air-O-Swiss Refill Granules.
    • Dimmer Control – Use the dimmer control to dim the brightness of the control panel display during the evening hours.  
    • Titanium Membrane Housing – Heavy-duty titanium membrane housing ensures long-lasting use and guarantees fast dispersal of mist throughout your environment.

    Comments about Air-O-Swiss U650 Digital Ultrasonic Warm & Cool Mist Humidifier:

    I used this constantly from October until May to humidify my dry NYC apartment. This is a nice humidifier which is quiet and easy to use, although filling is a bit challenging due to heaviness of the container and no carrying handle. But this is not an major problem unless you cannot carry a heavy container. The other big problem is changing the demineralization cartridge which fortunately does not happen often. You have to fill the container with granules, which is messy and you have to be VERY careful not to get the granules into the center of the container of it will ruin the dehumidifier. This happened to me--to be fair this info is in the owners manual but it is NOT on any of the packaging for the granules. I had to replace my humidifier after one year, which is a hard lesson to learn with such an expensive device.

    Comments about Air-O-Swiss U650 Digital Ultrasonic Warm & Cool Mist Humidifier:

    This product requires a little bit of cleaning now and then. I recommend some organic cleaning agent and refill crystals instead of buying the expensive replaceable module and trademarked materials. It adds moisture quite quickly, equipped with a sensitive touch panel, and if you read the manual, has some very handy features. With timed sleep, controlled moisture output, preheating for warm mists, I find this product quite useful. This product will require cleaning though. As for the build, its got the durability of a generic printer. If it drops, it's most likely going to be damaged. The accuracy to measure the humidity is also top notch. It starts from a high percentage and slowly trickles down so to not go off as it calibrates. What is also nice is that the water will stay cool in the tank even though it may be warm. This can be utilized to cool down the room if you wish for sometimes is what my purpose is. The preheat, with all heating, takes quite a bit of time. I wouldn't recommend it unless you are opening up the windows to let the cool night's air in. It's quite muggy otherwise. As for the humidifier's direction, you can have it point in two independent directions. I would estimate the mist comes out at a 60 degree incline and settles to the point where it doesn't touch the appliance. Finally, I would like to wrap up the overall value of this machine. Compared to crane, this machine definitely has its premium tricks. If your looking for something just to put out now and then, I would recommend something cheaper. If you're looking for something serious for the house to stay out in view for extended periods, then I would recommend investing more money. Air-O-Swiss could have a better build quality, but with competitors also going in the plastic direction, i'm glad their focus is on other innovations.
