This small humidifier is designed to fit on the top of any sized plastic water bottle. The Brookstone USB Bottle-Top Humidifier is not only versatile, it is also extremely portable. The tiny device addresses dry air anywhere you go.
The Satechi Humidifier is great when air is dry, but also mists when you need cooling down and functions as an aroma therapy diffuser as well. In the last case, all you have to do is add essential oil or fragrance to your bottle. It is designed to cover an area of 16.4 square feet (the size of a large bed) and comes with a replaceable filter that lasts 3 months with constant use.
The small humidifier is ideal for travelling and small spaces.
