  • Product Overview

    Enjoy soothing cool moisture that relieves your dry air symptoms and ultra-quiet operation with the Air-O-Swiss U200 Humidifier! This ultrasonic tabletop humidifier infuses your air with up to 1.8 gallons of invisible cool mist every 24 hours—all while remaining whisper-quiet so you can go about your day peacefully. The U200 is designed to treat small to medium areas up to 430 square and it's a great option for your bedroom, small living room, den, office, or any other area in your home that's prone to low humidity. Other key features include a mist output regulator, a refill indicator, and a demineralization cartridge to protect against mineral buildup.

    Ultra-Quiet Ultrasonic Humidification

    The Air-O-Swiss AOS U200 Humidifier uses ultrasonic technology to create a micro-fine mist that delicately blankets your air and boosts your indoor comfort. When compared to other popular humidification technologies, ultrasonic is by far the quietest way to increase your indoor humidity. The U200 cool mist humidifier operates at a whisper-quiet sound level of 25 decibels or less, making it ideal for your bedroom, nursery, or office.  

    Fresh Performance, No White Dust

    With the Air-O-Swiss U200 Ultrasonic Humidifier, you'll always enjoy fresh humidity with less frequent maintenance. This is especially beneficial if you're short on time. This unit uses the new Air-O-Swiss HydroCell advanced water maintenance system to ensure fresh performance in between regular cleanings. This disc-shaped insert uses activated carbon technology to help reduce heavy metals, odor-causing chemicals, pesticides, and other impurities that might be lurking in your tap water. The result is cleaner moisture, a cleaner tank, and less time to spend on maintenance. The U200 also features a demineralization cartridge that absorbs minerals from hard water that could lead to unhealthy white dust.

    Additional Features

    • Mist Regulator - Vary the level of moisture in your space by adjusting the mist output regulator with variable settings from low to high.
    • Light Dimmer - Dim the unit's bright blue light so you can sleep easier with one touch.
    • Empty Indicator with Auto Shutoff - The convenient empty indicator shuts off the humidifier and lets you know when it's time to refill the tank. You can also monitor the water level through the transparent window.
    • Fragrance Container - Add a few drops of your favorite fragrance to lightly freshen your air or drop in respiratory medication to further ease your symptoms.
    • AC/DC Adapter with Plugs - Choose from 110-120 or 220-240 voltage with exchangeable plugs and an AC/DC adapter.


    The ultra-quiet and compact Air-O-Swiss U200 Ultrasonic Humidifier infuses your indoors with up to 1.8 gallons of fresh cool moisture to relieve your dry air symptoms.
