This humidifier is a very small and portable; makes it very easy for people to use when they are on the road. Measuring roughly 4 x 3 x 3 inches, it is compact but heavy duty. To use simply buy a water bottle and screw the water bottle onto the humidifier. There are three settings or options on the humidifier: 1. Pressing on the button one time will have humidifier work at its maximum and produce the most mist. 2. Pressing the same button twice, will create a medium amount of mist. 3. Pressing the button three times, will have the humidifier at low setting. It is highly recommended to have the humidifier set at low setting. When using Option 1 and 2 place the humidifier on the edge of the table so the mist will disappear into the air by the time it hits the floor and prevent any dampening.
