For use in living spaces, bedrooms, and even your office at work, a room humidifier keeps relative humidity levels under control wherever you are.

Before purchasing a portable humidifier, measure the dimensions of the space in which you wish to use it. Calculating the square footage of your space before you buy will help ensure you select a room humidifier that works correctly and delivers the benefits you desire.
