What care do hearing aids need?
There are a few simple things to learn. Currently, there is no such thing as completely waterproof hearing aids, so it’s important to keep them dry – and safe from heavy rain. Special hearing aid dryers can remove moisture from inside. It is also important to keep them away from hairspray, which can damage the plastic. However, the main considerations they need are new batteries, which typically last for about a week. Some models allow for rechargeable batteries.
