Audiologist's Choice Hearing Aid Dehumidifier is a great way to eliminate that dangerous and unwanted moisture from your hearing aids. It's small and portable which makes it great to bring with with you on trips or vacations. The dehumidifer is large enough to hold two BTE hearing aids at one time. The Silica Gel pouch can be re-activated in a microwave or conventional oven making this dehumidifier reusable over and over again.
