SmartDryer Li-Ion is an electronic medical device designed to work with the Lithium-Ion hearing aid chargers from Sivantos. SmartDryer maintains the hearing aids by drying with hot air diffusion and cleaning with UV-C rays during charging. SmartDryer technology will eliminate humidity and substantially reduce bacteria, thus optimizing the performance of the hearing aids and maintaining the hygiene of the ear canal. It uniquely combines charging, drying and UV-cleaning in one device. This 3-in-1 user-friendly device performs three essential tasks for the daily maintenance of hearing aids.
