ABSTRACT:
An apparatus is disclosed for removing moisture from electronic devices such as hearing aids, using a desiccant material. The desiccant material is regenerated in place with heat from an embedded heater when the apparatus is open to the atmosphere. Drying of the hearing aids takes place when the hearing aids are placed in the apparatus and it is closed. Heat is not applied during drying to avoid potential damage to the hearing aids or other electronic device.
