how often and how long to use this?
my aids go in the dryer every night and the dry cycle is 30 minutes, My aids are ITE hearing aids with disposible batteries, so my aids live in the dryer when I am not wearing them
I bought the Hal-Hen activated alumina desiccant style dryer at Costco for less than $20. I have had it for a year now and it still does not need to be regenerated. I put my aids in it every night and essentially use it as a storage case for them, when they are not in my ears. No power needed, and easy to travel with. If you have rechargeable aids, then it is not going to work for you though.
