A humidifier (10) is provided having a housing (11), a conventional electric motor (12). a fan blade assembly (13), a conical suction tube (14), and a cylindrical water droplet diffusing screen (15) mounted concentrically about the suction tube. The housing defines a downward air channel (32) commencing at an air inlet (33) and which extends about the bottom edge (34) of a barrier to an upward air channel (37) terminating at an air outlet (38). The suction tube has a bottom opening (22) through which water may enter the interior space of the suction tube and a series of water outlets (23). The housing has a lower housing portion (25) which defines a water reservoir (28) adapted to hold a supply of water having a maximum water line (MWL). In use, water is drawn through the suction tube and expelled into the downward air channel as droplets. These droplets travel downwardly along the downward air channel wherein the airstream is then diverted upwardly, thereby causing heavier droplets to be withdrawn from the airstream. As the airstream continues upwardly within the upward air channel the heavier remaining droplets are also withdrawn from the airstream. As a result, the airstream exiting the humidifier contains only the smallest water droplets.
