  • Patent number: 5403233
    Abstract: A humidifier is constructed from basic units that have a rigid part supporting a hydrophilic part. A lower portion of a basic unit is disposed in a water-filled canal, and the upper portion is exposed to air, especially heated air from a heater. One embodiment is adapted for placement over a floor outlet for heated air to evaporate water from the canal into the heated air to increase the humidity thereof. This embodiment may be above or just below floor level. Various forms of covers are associated with the units.
