Serene Innovations, a maker of amplified phones and TV listening products, sells the DB-100 as a hearing aid dehumidifier and cleaner for hearing aids and cochlear implant accessories. Its main difference from the Dry & Store boxes is choice: you pick a 2, 4 or 8 hour cycle depending on how humid your surroundings are. The unit warms to 113°F at the press of a button, and a separate Refresh button runs what Serene describes as a cleaning function. Two small extras suit people who still use disposable batteries: a magnetic strip to keep batteries from getting lost and a built-in battery tester. At $62.95 on sale when we checked (regular $68.95), it is the cheapest heated dryer on this list. The caveats are temperature and documentation. 113°F is warmer than any other heated dryer listed here, and the product page does not address rechargeable hearing aids.
