The Satechi USB Portable Humidifier creates a soothing personal space at home, the office, in a car, or traveling. To use, fill a bottle or cup with purified water, place the humidifier into the opening, making sure the filter is submerged, & plug the humidifier into a USB port for instant comfort. To turn off, unplug it or wait until it automatically shuts off after 8 hours. You can then refill the bottle & plug the humidifier into a USB port to turn it back on.
