Review (5/5): Simple, low cost way to keep your tubing clear.
I use this in my class to quickly clear moisture from hearing aid tubes. When the tubes fill with a few drops of water it blocks any sound from going through. Simply remove the earmold tube and use the blower to clear out the moisture. You should also consider getting a Super Dri-Aid jar to keep your hearing aids in every night to keep them dry and clear of moisture.
