Perfect Dry Lux

Hi everyone

I have rechargable hearing aids and I’m considering purchasing a heated dehumidifer but the temperature it operates at is crucial.

From what I’ve read there are 2 versions of the PerfectDry Lux heated dehumidifier. Version 1 runs at 40 degrees C for use with disposable battery hearing aids and Version 2 runs at 35 degrees C.

Version 2 was brought out for use with rechargable hearing aids.

Can anyone tell me how to identify Version 1 and Version 2 as it is not made clear on PerfectDry Lux packaging which model is inside the box?

Thanks.

I hope you’re wrong, because I bought my Perfect Dry Lux 11 years ago for my Starkey Muses, and now I use it (with Costco’s blessing) with my new Rexton Reaches. They did not say anything about “make sure you use the newer model”.

I bought my Perfect Dry Lux at Costco about 3 months ago. I assume they (the hearing department) would sell the correct version. Prior to purchase, I researched this item and didn’t find different versions though. FYI, I didn’t buy my there just the dryer. The box is pretty plain but if you need me to check anything specific on it let me know.

Perfect Dry Lux

Initially, rechargeable hearing aids were never made for driers. So it’s good to see Perfect Dry Lux offered, especially for those living in humid areas. But the run cycle is only 45 minutes, which I find rather short. Is there a reason rechargeable hearing aids are not dried out for 2 to 4 hours, plus, versus the short time span of 45 minutes?

Also, could a HA manufacturer void a warranty or not repair aids if the user does not specifically use the rechargeable unit provided by the manufacturer? The next question is, will the Perfect Dry Lux recharge batteries of any aid brand?

My PDL doesn’t charge batteries. It just helps remove moisture and (if I understood, way back when) sanitize the aids. I use Rexton’s travel charger to actually charge my .

UPDATE: I just called Costco, and I asked the HA Center specialist who answered the phone if I needed to buy a different version of PDL for my new Rexton Reaches.

Her answer was: It should be fine to use the older PDL as long as I run it a shorter time, maybe about 10 minutes. She also mentioned that at Costco, sometimes they use the older PDLs with rechargeable HAs, such as loaners, and it doesn’t seem to cause any damage.
I did not think to ask, but now that I think about it, is 10 minutes enough to help remove moisture and sanitize the aids?

I’m confused. Obviously, I don’t want to buy a new version of PDL if my old version will safely do the job. But I’m still not clear as to whether running the old version just 10 minutes will achieve the desired result. If anyone has additional info on this, please advise, thanks!

Well, this is where it gets confusing. With disposable aids, you can cook a hearing aid for any extended period of time. Be it with heat or ultralight. Two hours to say eight hours won’t impact the hearing aid, though if batteries are left in the aids, they will be slightly drained. Very slightly, like no big deal. Now I have no idea how long a rechargeable hearing aid can be left in a hearing aid dryer. I might be concerned about using a rechargeable aid dryer if it wasn’t made by the actual hearing aid manufacturer. Maybe someone else can add to the discussion regarding the safety of using a dryer like the Perfect Dry Lux, and how long it should be turned on when drying out rechargeable hearing aids that are attached to rechargeable batteries.

From what i have read and learned through contact with Resound, their rechargable hearing aids should not be dehumidified in devices operating at a temperature greater than 35C (95F).

The PerfectDry Lux is available in 2 versions. One version for disposable battery hearing aids that operates between 40C - 45C (104F - 113F) and a second version that operates at a lower temperature suitable for rechargable hearing aids, that operates at 35C (95F).

The rechargable friendly PerfectDry Lux has a standard operating cycle that lasts 45 minutes. After this time the device switches off.

Its confusing for users that several hearing aid manufacturers have at various times sold rebranded versions of the PerfectDry Lux but not made it crystal clear on the packaging exactly which version is inside.

From my reading and the help of other forum users I’m now aware that the only way to tell the two devices apart is to look at the code at the very start of the serial number thats printed on the bottom of the actual device.

**** Rechargable safe model serial code starts with PDLC

** Disposable battery model serial code starts with PDLO

Thanks for clarifying things. But I will add if anyone lives in hot, humid weather or locations with long, hot summer you’d be wise to get a hearing aid dryer. For many years, that was my main concern with rechargeable aids, since there was no way to dry them at night or when not in use. Sorry, but I don’t put much faith in a dehumidifier jar or a drying aid jar. Especially when humidity kicks up, May through September in the South. But I’d need to read more to make sure rechargeable batteries can coexist with powered aid dryers. Say for 45 minutes to an hour, day in, day out?

I’ve been using the low-temperature PDLC variant with my rechargeable hearing aids (Oticon Real) on a daily basis for about 9.5 months. So far, I haven’t noticed any deterioration in battery performance. My primary reason for using the device isn’t drying, but rather the sanitization of my earmolds using the built-in UV-C lamp.

I’m making an educated gues here that the rechargeable batteries are lithium and manufacturers will specify shorter and cooler temps because prolonged excessive heat can accelerate aging so shortening battery life. Short battery life would give the ’s a bad reputation so they are playing it safe I.M.H.O.

I follow you and its some what obvious that there’s not one hearing aid company pushing “dry your rechargeable aids” when using in high humidity. So those who wear rechragable ’s in tropical climates, high humidity areas, desert, near equator, etc., need to bypass aid dryers to prolong the use of the rechareable battery. Thus battery welfare takes precident over the actual hearing aid which most likely will start to malfunction at some point due to interior moisture in aid body or turbing. Seems we are robbing Peter here to pay Paul, since the HA (body) is way more important than little recharegable batteries.

I’m waiting (and hoping) to get a definitive response from MG Developpement (manufacturer of PerfectDry Lux).

I emailed them asking whether the older model of PerfectDry Lux could work effectively with rechargeable hearing aids. And if the answer was yes, were modifications required, such as a shorter cycle time? I also provided my serial number from the bottom of my existing (old) unit. Hopefully, they will reply soon.

In the meantime, I stopped by Costco today to purchase the newer version. They didn’t have a unit on hand, but they placed an order and will let me know when it comes in. I figure, better safe than sorry.

Trouble is - The little rechargeable battery is every bit as imprtant as the body as without the battery, the body doesn’t work and the battery is inside the body. Also there is the problem of sourcing a replacement if you are the kind of person who would attempt to open the expensive body. Sure you could send it in to get the battery replaced but that would mean waiting an indeterminate amount of time. What should be the argument is that if a HA user purchases HA’s in a location that ‘requires’ the aids to be dried then a suitable dryer should be supplied along with the HA’s. Sure it would increase the cost a bit but you would know that the dryer was the correct one. In the UK we don’t have troublesome humudity - Just torrential rains & if you are like me, getting in the shower before taking them off.
