Dryboost UV dry and store for rechargeables

For YEARS I used the Dry & Store model of HA dryer/UV sanitizer. I’ve gone from the huge, jewelry-box sized units 20-odd years ago to the portable Global. You’ve probably seen the reviews at Amazon - about 70% rank DryBoost 5-star. So it could be a good purchase for you.

Given that aids may cost from $2K to $7K per pair, you have to also weigh how much is it worth to ensure maximum protection from humidity, and does the unit also sterilize the aids?

I’ve got both portable and very high-end UV/sanitizer units. Like insurance, I just want the extra peace-of-mind that comes with the units I’ve purchased.

You’ll be the best judge. If your aids are flaky, it’s likely due to moisture. If they make your ears itch, it could be they need some UV sanitization. Keep us posted.

Your recharger is a dryer. While charging, it warms up the battery inside the aids high enough to cause moisture to leave the aids themselves.

This idea is new to me, and I have some comments/questions.

You do say that only the aids themselves get dried. But receivers and molds and tubing also need to be dried. Maybe even more so, since they’re exposed to moisture inside the ear.

The battery gets warm during charging, and heat transfers from there to the rest of the aid. This involves a temperature gradient – temperature goes down the further away you get from the battery. This is true even in a closed charger, and the gradient will be steeper in an open charger. How hot does the battery have to be, in order for outside parts of the aids (microphones, receiver in BTE aids) to get warm enough to be dried effectively during the time the aids are actively charging? Considering that rechargeable aids aren’t supposed to be dried in a regular dryer at 113°F to avoid damaging the batteries, presumably the battery doesn’t heat up all that much during charging. So I question whether the battery gets hot enough to warm the aid enough to dry it effectively.
