Hearing aids and earwax

Hearing aids are usually in a pretty hostile environment - your ears! It is hot and sweaty in there and, for many people, there is some ear wax too. Hearing aids need some care to keep them in good working order, a bit part of that care is making sure that they are clear of wax. An in-the-ear or in-the-canal hearing aid will have a wax filter in them, which is located at the end of the hearing aid that sits deepest in your ear and is a thin mesh which blocks any wax coming out of your ear.

The wax filter should be changed to make sure it doesn't have a lot of wax built up against it, this will stop you from hearing so well as any sounds coming in to your ear are having to travel through a layer of wax. How often does the filter need changing? Depends on how much wax you produce, if you aren't sure ask your hearing aid provider.
