Hal Hen Dri Aid FAQ
I have had quite a few emalis from people asking about Hal Hen’s dehumidifier products since I posted this. I’ve compiled some of the questions into a short FAQ below:
Do they work?
Yes! I have been leaving my Siemens ITEs in the pot overnight twice a week for years and I honestly believe that the dehumidification process has prolonged their life. On a couple of occasions I have got some rain-water in my aid and it has stopped working – a day or two in the Dri Aid pot has always managed to dry it out and get if fully operational again.
Where can I buy them?
The Hal Hen webiste has a contact form – if you fill that in they will let you know where your nearest stockist is. Alternatively, phone or email hearing aid vendors in your local area as Dri Aid products seem to be widely stocked by most vendors. You may also find some online stores selling them but I have no bought one online so I could not recommend any particular website.
How long do they last for?
I have had a Super Dri Aid pot for well over five years now and, as far as I can see, it is still working as well now as the day I got it! As long as you mircowave the pellets when you need to – you’ll know you need to mircowave them when the blue ones turn white – you should get a few years of service from a Dri Aid pot.
How much do they cost?
Super Dri Aid and Mini Super Dri Aid usually retail for between $15 and $20 in the USA and between £7 and £18 and the UK.

Hi Steve,
Two comments on moisture in hearing adis
(i) Hal-Hen Dri-Aid dehumidifiers.
Mine has finally given up the ghost after 14 years of constant use. A reactivation now only lasts about 1 week now compared to over 6 months when new.
I have always reactivated usinig a microwave and not an oven.
The daily use of this dehumidifier ensured that my Phonak Pico (BTE) lasted 12 years. I now have a Oticon Epoq with a remote Streamer – fabulous- can use bluetooth to connect to mobile phone, TV and home phone. The downside, cannot turn the streamer off and this can cause some issues with three remote connections.
(ii) Full immersion of hearing aids
IF you do manage to submerse your hearing aid in water the first thing is to remove the battery as quickly as possible to avoid short circuits. Then you can try to dry it out. If the submersion is not too bad, your use of the dehumidifier is OK, but if bad then you need to remove all water from the aid. The best means is to use a pure alcohol solution as this displaces all water and evaporates without leaving any residue (like WD40 does). Unfortunately, obtaining pure alcohol is no longer that easy. Shellite (also known as X55) is almost pure methyl alcohol and it was used for many years as a cleaning agent for mechanical office machines. It is excellent if you can get it. Just immerse your hearing aid into the stuff, swish it around to ensure the whole interior is washed and then leave it out to dry (many need up to a day if you cannot get the case open).
Of course if you drop the aid in salt water, then goodnight. There is just no way you can ever get the corrosion out of it. The alcohol will get most out but salt water corrosion will eventually kill your hearing aid well before its normal lifetime.
