Hal-Hen Super Dri-Aid

Does anyone on this forum use the Hal-Hen Super Dri-Aid, and if so, how long does a jar usually last for you? I live in a really dry climate - not quite desert-like, but with very low humidity - and I take my aids out whenever I exercise, don’t wear them in the rain or shower, and generally don’t have a problem with excess ear wax. But I’m finding the jar is only lasting 6 months before needing replacement. The pellets that come with the jar are to be “rejuvenated” once their absorption level decreases. I’ve followed the microwave rejuvenation directions exactly two separate times now, and while the pellets do change back to their original blue (absorptive) state, they only stay blue for about half an hour, and seem to fade (indicating a lack of absorptive ability) as soon as I put them back in the jar. I’ve been letting them cool off completely before returning them to the jar.

My original jar, which I used for 18 months with only 1 hearing aid, was replaced back in June of this year, because despite my following the microwave directions, I just couldn’t get the pellets to rejuvenate even one time. As of two days ago, the pellets in the new jar were showing a need for rejuvenation, which means the current jar has lasted only 7 months with two hearing aids. Their website claims that a user should be able to get several years of use from one jar, but that certainly hasn’t been my experience. Thoughts? My microwave is new and is of decent quality. It cooks all other foods in the appropriate amount of time, so I’ve ruled out a problem with it. I wrote to Hal-Hen to see if they can offer any suggestions, but thought I’d also ask here.

Can someone recommend another good option for a dry store container? I’d prefer to use something that doesn’t require electricity, but am open to the fact that a unit which plugs in might be my best bet. Thanks in advance!


I use the Sta-Dri can which sounds the same except the desiccant is pink. ($10 Amazon) I’d had it for several years when a spot overheated and loosed the granules Got it overheated somehow. So, I replaced it. I put the canister back in after a minute or so when its has cooled a bit.

Was still working fine when the canister melted.

After writing to Hal Hen to ask what I’m doing wrong, I got a very personal response in the form of a phone call from their head office a few days ago. In case anyone else uses this brand of dry jar, here’s what I was told:

-When the coloured balls lose their colour, it’s time to rejuvenate them.

-Place all of the balls (dessicant) in the microwave on a pyrex dish and microwave them for 30-60 seconds at 50% power. (DO NOT microwave the balls while still in the jar. Use a separate, microwave safe glass dish.) The instructions that come with them say to microwave them in 30 second increments, but the Hal Hen customer rep said 30-60 seconds is fine, as long as it’s only at 50% power.

-He said that you can keep microwaving them until the bright blue balls stay blue. Mine were fading after they were cooling off. So he told me that I needed to microwave them several times in short increments until the bright blue colour reappeared. He said some people he’s spoken with have had to microwave them for up to 15 minutes, all in 30-60 second increments. I had to put mine in the microwave for a total of 9 to 10 minutes, but now the blue colour has been restored, so hopefully the jar is doing its job again.

I live in a really dry climate and don’t have much ear wax, so I’m not sure why I’m needing to rejuvenate my dry aid dessicant so frequently, but I am. At least now I know how to do it.

The gentleman I spoke with from Hal Hen was extremely helpful and gave me his direct line to contact him again if I had any questions. I’m quite pleased with the service I received. Now I’m going to give my audiologist his instructions, as she had no idea that the dessicant may need to be microwaved more than once or twice; hence the reason we replaced my last jar a few months ago.

I hope this can help someone else!
