Designed for medium-size rooms, this ultrasonic humidifier increases the benefits of good air quality and provides relief from some of the harmful effects associated with dry air. The unit produces a cool mist that can be seen and felt, plus it offers variable mist control with its easy-to-use control dial. A full tank will emit moisture for up to 24 hours, and the permanent filter washes clean easily and can be reused so it never has to be replaced. In addition, the filter traps impurities from the air thanks to its Microban antimicrobial protection, which inhibits the growth of odor-causing bacteria and mold. With its sleek attractive design and virtually silent operation, the humidifier measures 11-3/4 by 10-7/8 by 17-1/6 inches and carries a one-year warranty on parts and labor.

Frequently Asked Questions

  • How well does this handle hard water? Is there a mineral buildup issue?

    I'm in Atlanta and I believe our water is a bit on the hard side. So after using this unit for five years I typically see a reddish tint on the white plastic and where there is a dime size metal piece inside it will get some lime scaling after a seasons use.

  • Water tank capacity?

    1.3 gallons.
