Super Dri Aid Hearing Aid Dehumidifier - Single Dryer

This product keeps my hearing dry on the inside. It protects them from moisture damage. It is a great product and you can't beat the price.

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.

this is a replacement for and old one It does the job

I've had hearing-aids since I was a child. These are just like the ones I've used before. I definitely recommend these.

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.

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.

Keep it simple! This is my second Hal-Hen super Dri. I still have and use the original that I bought over 10 years ago. Needed one for travel; kept forgetting to pack it! Over the years I’ve tried a couple of electric driers but I still prefer this drier best. My simple test for how well a drier works is how easily ear wax flakes off when I take my HAs out of the drier. Super Dri wins hands down. No replaceable descant cartridges to buy, just heat up the beads in microwave when the blue beads fade and you’re good to go for months! And unlike electric driers, they don’t heat up your HAs. Heat and electronics, as a rule, don’t mix well.One time I forgot and wore my HAs into the shower. Thought they were ruined. Left them in the Hal-Hen Super Dri for 2 days and they were fine. Never had any issues afterwards. Can’t go wrong with this drier.

There is less of the drying beads in the jar than my previous purchase. I have now tried this product out for a few months and it just doesn't work. The ear wax would be dry and easy to remove but now it doesn't dry at all which means the beads are not working and that is bad for the hearing aids. If someone reaches out to me to send me beads to fill out what is missing in the jar I will change my review otherwise I will be buying a product for someone else and will never purchase anything from Twain and Moss(seller's name) ever again.
