This humidifier is best described as a cool moisture humidifier. It humidifies the air without producing a mist (mist would make wet spots around the unit and could create mineral deposits on the floor or in carpet); this unit traps minerals from the water in the wicking filter. There are a number of modes. The most useful to me are the modes to maintain constant humidity. I chose this model because it is used to control the humidity for guitars. The humidified air is directed up so it does not blow directly on the guitars which are highly sensitive to changes in humidity.
This diffuser doubles as a humidifier and is wonderful because of its small size. I have had it for a few weeks and this little guy is a workhorse. Truly a great purchase.
