Protect Hearing Aids From Moisture

Protect Your Hearing Aids From Moisture

Moisture in hearing aids slowly corrodes the components.  Then moisture makes its way onto the batteries and reduces their effectiveness.  Continuing on its path of destruction, moisture travels down the hearing aid tubing where it condenses into tiny drops and eventually infiltrates the filters inside the ear hooks.  During this process the hearing aid will slowly lose clarity and amplification until it finally gives up completely.

My daughter believes that I have magical powers because I make quarters appear from behind her ears.  I tell her that is because I am an audiologist and I specialize in ears.  Although the battle against an invisible enemy like moisture sounds like it would require magic, there is no magic needed.  By employing some simple preventative measures and cleaning techniques listed below, you can almost completely banish this enemy from your hearing aids.

Dry Storage:

  • There are two different devices that work to dry out your hearing aid while it is not in use:
    • A dri-aid kit is small and inexpensive device that contains silica crystals. The silica crystals will absorb moisture from the hearing aid overnight.  The silica crystals are dried when it is placed inside an oven.
    • A Dry & Store machine is an electrical device that uses heat, moving air, and silica crystals or a similar substance to remove moisture from a hearing aid.  The machine also has a germicidal lamp which helps kill bacteria, molds, or fungi that may be growing on the surface of the hearing aid and it also helps to reduce odors.

Battery Cleaning:

  • To keep battery contacts clean, use a Q-tip that is dipped in isopropyl alcohol and rub the contacts.  Battery contacts with corrosion may cause an unwanted “frying” noise and less efficient use of the battery.

Tube Cleaning:

  • To remove moisture from the tubing, the tubing must be disconnected from the hearing aid. Then gently blow air through the tube until it is dry.  A can of compressed air from an office store works great for this.


Using these methods you too can fight the effects of moisture on your hearing aids and make them last longer and make the world sound better.  Please join me in this battle and I am confident we can win!
