ABSTRACT:
A humidor and method for high humidity, ambient temperature storage of items includes a water reservoir with a relatively large surface area which is gradually and uniformly heated in response to a humidity sensor. The temperature in the reservoir is raised at a rate of less than 1 degree Fahrenheit per 4 minutes to a maintained temperature of less than 5 degrees F. above ambient temperature until a desired humidity level is reached. The humidor enclosure includes convection heating elements which create a convection current between air inlets and outlets to draw fresh air into the humidor. A water level sensor in the water reservoir deactivates the reservoir heater and convection heating elements when the water level drops below a minimum level and simultaneously actives a water level low warning signal.
