Hal Hen Super Dri Aid

Hal Hen is an (oddly named) company that supplies many different types of hearing products. Their Super Dri AidTM and Mini Super Dri AidTM are dehumidifiers for your hearing aid.

Moisture is very, very bad news for your hearing aid. Dampness, sweat and humidity will shorten the lifespan of your battery and cause it to corrode. You can cause permanent damage to your aid if you allow excessive moisture to build up inside it; dropping it in water isn’t a good idea either, but I don’t think Dir Aid will help you out there!

Both the Super and Super Mini products are a glass pot, which is about 2/3 full with pellets. These pellets suck the moisture from your hearing aid once you have placed it inside and screwed the lid shut. Always remove the battery before you leave your aid in the pot. The pot contains white and blue pellets, the blue ones will fade to white after repeated use – once this starts to happen, the pellets have become saturated and it is time to dry them out. To do this, you simply empty the pellets onto a dish, cover them with a second dish and put them in the microwave for a short time.

I’ve been using a Super Dri Aid pot for years. I’ve had my current set of hearing aids for about 5 years now, I’m certain that regular overnight use of the Dri Aid pot has helped to prolong their life.

  1. My pellets no longer return to blue but become a deep brown. Are they still effective?

  2. Hi Bob,

    I’ve been using the same Dri Aid pot for years and get the odd brown one now and again when I recharge.

    I assume the brown ones have been burnt.

    If your pot if full of brown pellets then it might be time to get yourself a new one!


  3. I recently received a Drying Pot from the Mayo Clinic when I picked up my hearing aids. The instruction provided with the aids strictly forbid using a Microwave for reviving the pellets. They also say a regular oven must be used, once a month.
    These instructions do not agree with those printed on the pot.
    Which should I follow? The Microwave would be the most convenient for me.
    Thank you.

  4. Dr Lindsay,

    Is it possible that the clinic gave you the wrong set of instructions with your Dri Aid pot?

    Rather than me make any assumptions here, I would suggest giving the Mayo Clinic a call.

    I don’t think you will need to charge the pellets every month, just when the blue pellets turn white. The speed of the whitening process will depend on how often you put your hearing aids into the pot and and how much moisture they contain.


  5. Thank you for your acknowledgement. The technician, while demonstrating the Hal Hen Super Dri-Aid, was quite specific, verbally, about never using the microwave, and also about recharging on a monthly basis.
    This is not the only confusion. One instructor told me to brush the hearing aid filters (though the manufacturer says not to touch them). Another said: “never brush the filters!”
    Confusion reigns!

  6. Hi,

    I am writing from Mexico.

    My mother has used this item for a long time and we have seen that it is really good, but that we have at this moment is close to get its life period, so would like to know where we can purchase it in Mexico.

    Comments are highly appreciated!!

  7. I need to know if I can just buy the pellets or do I need to purchase a new Jar. If I can just buy the pellets please let me know how to get them thank you.

  8. Peggy,

    As far as I am aware you will need to buy a new jar.

    I don’t know where you live but here in the UK you can pick up a new jar from Specsavers – they sell a jar made by Siemens for £6. You should be able to buy jars from most hearing aid vendors.

  9. re Hal-hen super dri- aid

    I may sound a silly question but it doesnt say anywhwere if you need to remove the grey sponge on top of the pellets before putting in you hearing aids?
    and I have had this jar about 3 years and no matter how I heat it none of them turn blue.

    I am presently experiencing a problem with on of my hearing aids so shall ask them at the ha centre but would like to hear what you have to say .
    Many thanks

  10. Liz.

    I removed the sponge from my Dri Aid pot and just put my hearing aids directly on top of the pellets. I think though, the proper use is to put your hearing aids on top of the sponge.

    If you only have white pellets then your pot is not removing any moisture from your aids. My method to dry the pellets out is:

    1. Empty pellets onto a plate
    2. Flip a second plate over and place it on top of the first plate. So your pellets are no incased between the two plates and cannot jump around in the microwave.
    3. Put plates in the microwave and turn it on full power for 1 minute.
    4. After 1 minute lift top plate off and see if any blue pellets have appeared. Replace top plate and heat for another minute.

    BE VERY CAREFUL when lifting the top plate as the pellets get very hot and let off a lot of steam.

  11. The instructions from Hal-Hen explicitly state the pellets should be placed for 30 minutes in a 350 degree oven to remove the moisture. It also states that this should be done only when the blue pellets lose their color, which for me takes several months. After the oven treatment, the blue pellets regain their color.
    I don’t think using a microwave is a good idea.

  12. Only just found your site. Ive had my MINI-DRI-AID 3 yrs and the chemical in the wndow has never turned PINK. Also, there are no instructions on the jar to open the metal container and take the pellets out. Do I have an obsolete product or what?
    I still use it whenever Ichange batteries but i dont know whether it does anything.
    Advice please

  13. Hi there,

    I have had my mini dri aid for about 18 months now and the pellets are all white.. so I put them in the oven and some of them turned blue like they are supposed to.. but when they cool off they are all white again.. does this mean they are not working? I was wondering if I need to heat them in the oven again or buy a new one..

    This is the first time I have ever had to recharge them so I have no idea. I called the clinic where I got it and my hearing aid from and they didn’t know either!



  14. Hello:

    When the pellets stay white after heating you need to purchase more. My problem is I can’t find a web site that sells this. All of the web sites that I have found explain what the pellets do but do not sell it.
    Does anyone know where I can purchase a new jar of Mini Super Dri-Aid?






  16. I always remove the batteries. There is no reason to dry them. By removing them, you add another 8-9 hours of life to them (depending on how long you have them in the Dri-Aid) and, considering how short the battery life-span is, that is significant.

  17. Save the little white bags that say, “Slica Gel- Do Not Eat” from things you purchase such as cameras, computers and the like. Put them on a cookie sheet and bake them in the oven at no more than 300 degrees farenheit for about 30 minutes. Put the bags in a dry air-tight container and put your hearing aids in the jar.

    Silica Gel adsorbs water vapor molecules in the jar and dries out the hearing aids. Once a month or so, slowly bake the bags as shown above to get rid ofthe water molecules and put them back in the jar. Other adsorbents are:

    Activate Alumina
    Clay based kitty litter
    Crushed Zeolite
    Activated Charcoal aka activated carbon

    All of these can be regenerated by carefully heating them in an oven, preferably an electric oven since a gas oven produces water vapor as a byproduct of combustion. A microwave oven is iffy IMO since it heats unevenly. But maybe putting a dish on top of the pellets helps even out the microwave radiation to prevent overheating and damage to the pellets that happen to be in the “hottest” part of the microwave oven.

  18. I can’t find any information about the safety or toxicity of pellets. My instructions say to use a Pyrex bowl/pan to heat the pellets. I want to know if the bowl/pan/dish that I use is safe to use for food. Should I use something just for heating the pellets?

  21. i need to buy another jar of mini super dri-aid pellets.where can i do this?

  22. I just purchased another jar of Super Dri-Aid pellets. How do I properly disposed of my used ones?

  23. Why remove the batteries when placing the hearing aids into the drier? The batteries should not be affected in any way by the drying compound. They appear to be sealed from the affects of moisture – so it should make no difference. If they could stay with the aids, it would help me considerably. My arthritic fingers find it quite difficult to just pick them up.

    Thank you for your consideration.

  24. I have been trying to get in touch with Hal-Hen to see where I can purchase various items. I am currently wearing two Oticon hearing aids and have been using your products. Please call me at 908-581-9806 or email me at address above.

  25. Hi.. this is my first time buying the Hal-Hen(last month) where I bought the hearing aid (Chili 7). I’ve been wearing this aid for 4 yrs never had a problem. During my stay in mexico recently in feb..I’ve experience that my aid was shutting off on it own ..restart it by reopening then close the battery compartment. works for a while then repeat again. I’ve been going to mexico every year and never had a problem till recently. Had it fix a month ago for cleaning then last week it start again.. shutting off. so I’m asking you will the super dri-aid works even the humidity here is low.?? ….Thanks….

  26. Can I remove the batteries from my hearing aids and store them loosely overnight inside the Hal-Hen dry aid container with my hearing aids??

  27. Hi Nancy,

    It is recommended that you don’t leave your batteries inside the container – it can shorten their lifespan.
