Abstract
A humidifier having a reservoir, an exhaust opening, and a humidification unit including a motor driven fan with a suction tube attached thereto, a diffusion screen, and an intake opening. Water is drawn from the reservoir through the suction tube and dispersed towards the diffusion screen to cause mist which is combined with air drawn through the intake opening by the fan and expelled through the exhaust opening. An integral latch mechanism removably and replaceably attaches the suction tube to the fan to facilitate cleaning of the tube.
