Super Dri Aid Hearing Aid Dehumidifier - Single Dryer

Halhen is a molecular sieve desiccant. These come in various forms, for various purposes. This is for a adsorbing water -- for me, from my hearing aids. Dry circuitry lasts longer than damp circuitry, and while my hearing aids are ip67, I do place them in the Hal-Hen jar any time I shower. In addition to the new jar purchased in Jan, 2024, I have an older one from 2010. The older one has been reconstituted (baked 1/2 hr at 350F) many times in that interim. It continues to work, but I needed a second for another reason. I note that the 2024 version has about 1/2 of the molecular sieve that the 2010 version has. Thus, I expect to bake it twice as much. I consider this an inconvenience, as well as a cost/per that exceeded my expectations. One other use I've found is to reconstitute my silica desiccant capsules used in my hearing aid charger. A day in the jar, and the capsule has the proper color for a fully-charged desiccant. When charged, I keep the silica capsules in a small enclosed container. These capsules are incapable of being reconstituted via heat, and are considered disposable. Bottom line: Pro -- best desiccant I've found for hearing aids. Con -- much less desiccant per jar than previously.

We use Hal-Hen Super Dri-Aid for behind the ear instruments, and they work fine - accommodating the aids with no problem. The jar is very sturdy glass, though we have purchased plastic watertight jars at REI for travel (lightness and no glass). The jar we are currently using is about three years old, and the pellets can easily be reactivated to this date, though a few have fractured and we will be purchasing another jar. Given some apparent confusion and contradictory information, the jar instructions state: When to reactivate: (When blue pellets are white, like the others, it's time to reactivate.) How to reactivate: "Spread the Super Dri-Aid Pellets in a Pyrex microwave safe container... place in a regular household oven at 350 deg. F for 30 minutes - OR in a microwave oven with setting at MEDIUM and bake for 2 1/2 minute intervals until Blue Pellets return. Allow pellets to cool before placing back in jar. Normally each recharge will last between three and four months, depending on conditions. DO NOT place in broiler or open flame or cook in a pan over open flame. DO NOT at any time place the hearing aid or this jar in any oven. So, microwave or regular ovens are acceptable, and the clue is not about time, it's about the blue pellets whitening. The pellets last until they no longer turn blue or until they begin splitting or fracturing. Not a super cheap product, but a very good and cost-effective product that enables one to take proper care of a set of instruments costing thousands of dollars and extending their life.

This product does what it's meant to do -- remove moisture from your hearing aids. It uses drying beads that can be refreshed as needed by warming them in the oven once every few months. The beads change color to let you know when a refresh is needed. They rest under a layer of foam in the jar. In my case the beads were still fine but the foam started wearing out so it was time for a new jar. All in all a very good product.

I have been using this product for 10 years to help protect my hearing aids. After 10 years, I finally needed a replacement (the old one wasn't drying enough). I think 10 years is pretty impressive and worth the money ($20). Easy to use. Simple yet, highly effective, especially for me living in hot and HUMID Florida. Excessive moisture is a way of life here and this saves my hearing aids from expensive repairs

It's really easy to tell when it's time to "recharge." (You heat it in the microwave or oven.) There's a large quantity of drying material inside, so it's very effective. It's a heavy glass jar -- not easy to break or knock over. Someone else said there's not quite enough room inside. Not so, seems to me. My hearing aids are behind-the-ear, so they're not tiny. There's plenty of room. If you have really, really big hearing aids, you can dump out some of the drying material to make more room. On the other hand, this product is not sold or shipped by Amazon, so you don't get Amazon's reasonable shipping rates. Instead the product costs $15 and shipping is $7.50. The actual shipping cost is probably around a dollar. This is insulting and offensive. Do they think we are stupid? An honest seller would charge actual shipping cost, and raise the price, if necessary to make a fair profit. I thought about three stars for this reason alone, but decided on four instead.

Great product. Great price. Fast delivery too.

The OG. Good for hearing aids with replaceable batteries or rechargeable batteries. It’s humid here on the farm and I like knowing that I’m not messing up my hearing aids with farm moisture.

Cheaper desicants do a better job. There was condensation in my son’s ear molds that we could not get out. 3 nights in this recently refreshed Super Dri container did nothing. One night in the plastic case with the standard orange drying pack and the condensation was gone. I like that it’s not plastic and reusable/rechargeable, but it’s not as effective.
