An inhaler device which includes a wick which draws water from a reservoir and which is in contact with a heated plate. Air is directed over the heated wick surface by means of a fan thereby to produce a stream of heated humid air. A sensor monitors the temperature of the heated air stream and a control circuit which is responsive to the sensor maintains this temperature substantially constant at a predetermined value. The heated humid air stream is available for inhalation by a patient for the treatment of certain ailments.
