Abstract
A desiccant system in which a body of water-vapor-adsorbing desiccant material is sealed in a bag which is permeable to water vapor, but not to liquid water or particulates. A humidity indicator is sealed to the bag, and is sensitive to humidity within the bag, but not to water or water vapor outside the bag. The indicator changes color when a predetermined humidity level has been reached within the bag, and thereby to signal that the bag should be replaced.
