A hearing aid worn in the ear and ear canal and provided with a replaceable container of desiccant material. The hearing aid comprises a body containing an electronic sound amplification circuit and an appropriate replaceable power source such as a battery. The body is generally molded of a plastic material and is custom fit to the ear and ear canal in which it is to be worn. The body is provided with at least one port connecting the body interior with the ear canal. The desiccant container is replaceably mounted within the body to maintain the ear canal substantially moisture free to reduce or eliminate moisture induced irritation of the ear canal. The desiccant container is preferably associated with the battery so that both are replaced simultaneously and preferably as a single unit in a single operation.
