The Zephyr by Dry & Store is an electrical dryer/dehumidifier for nightly use at home. It is an effective storage and maintenance for all types of hearing instruments, including hearing aids, cochlear implant hardware, noise/tinnitus maskers, and in-ear monitors. The Zephyr operates on an 8-hour cycle, utilizing warm, moving air to remove moisture and a desiccant (drying agent), a proven technology for maximum drying effectiveness. The Zephyr is a value-priced dryer that does not sacrifice drying technology or the quality standard set by other Dry & Store products. The Zephyr utilizes the replaceable Dry-Brik II desiccant blocks, which are sold separately. Dry-Briks should be replaced after 2 months of use and have a shelf life of 2 years.
