  • Product Overview

    The PureGuardian H900 Ultrasonic Humidifier is perfect for adding moisture to rooms up to 150 square feet. Use it in your office cubicle, hotel room, or dorm room. The H900 includes Silver Clean Technology for less maintenance, near-silent ultrasonic operation, a water shortage indicator, 2 fan speeds, and a night light. It runs for up to 10 hours before you need to refill the tank, emitting up to 0.5 gallons of moisture per day.

    Indoor Air Comfort on the Go

    Whether you’re traveling for work or simply want a portable humidifier to use in your cubicle, the Pure Guardian H900 can reduce your cold symptoms and dry skin wherever you need to be. Weighing just 1.1 pounds and standing 8.5 inches tall, this humidifier stows easily into a luggage bag, and takes up a small amount of surface space.

    Silver Clean Technology Simplifies Maintenance

    Formerly known as GermGuardian, PureGuardian has added its Silver Clean Technology to the H900. Silver particles within the water tank destroy mold and mildew on contact, resulting in less cleaning for you. This also adds to the life of the humidifier and creates cleaner mist.

    Near-Silent Operation

    The H900 Ultrasonic Humidifier features ultrasonic operation, in which a metal diaphragm vibrates to break up water molecules into ultra-fine mist. These ultrasonic frequencies are inaudible, resulting in quieter operation than most other humidifiers. 

    Additional Features

    • Night Light —A handy night light provides low-key lighting during the overnight hours.
    • Energy-Efficient—This humidifier uses only 12 watts of power, using about 25% less power as the lowest-watt light bulbs on the market.
    • No Replacement Parts—There are no wicks, filters, or cartridges to replace, cutting down on the cost of upkeep.
    • Pink and Blue Models—Choose between the pink or blue model to give your space personality.


    The PureGuardian H900 10-Hour Ultrasonic Humidifier effectively adds up to 0.5 gallons of mist to a 150-square-foot space per day.

    What Customers Love

    • Light Cleaning and Maintenance—Silver Clean Technology makes maintenance less of a hassle by inhibiting the growth of mold and mildew inside the tank.
    • Near-Silent Operation—Ultrasonic technology offers ultra-quiet operation.
    • Portable—Weighing just 1 pound and 8.5 inches tall, this humidifier travels easily.

    Things to Consider

    • Basic Features—The H900 features basic controls. Choose another PureGuardian humidifier if you're looking for additional features like mist output control.

          Comments about PureGuardian 10-Hour Ultrasonic Tabletop Humidifier - H900:

          I bought this because I have chronic sinusitis and our dry winter air aggravates it. I run this unit every night with fresh water and clean it once a week with vinegar. I use our hard well water so it has to be cleaned regularly, distilled water is too much trouble. I wish the tank were a bit bigger to go through the entire night, it runs out after about 6-7 hours.


          a great humidifier!
