The USB Doughnut Humidifier provides a great way for people to stay naturally moisturized in confined, dry spaces. Take the office, as an example. A person's cubicle does not necessarily offer enough space for a standard humidifier, not to mention such public areas are often incredibly dry. The USB Doughnut Humidifier sits easily on a person's desk to ensure direct moisture contact without taking up too much space.
To work, the USB Doughnut Humidifier simply needs to be plugged into a computer port and then placed into any glass or cup of water. Thus it requires no separate water tank. It is available in three colors (white, pink and blue) and also boasts a timer feature so that it isn't left running unattended.
