General Questions


Why do you call it a conditioning system?
Dry & Store is not simply a dryer, and moisture removal is just one of its benefits. The Dry & Store appliances also dry cerumen for easier removal from hearing aids and deodorizes the hearing aids. A UV-C lamp (included in the DryBoost UV, DryCaddy UV, DryKlean UV, DryMax UV, Global, Global II, and Professional models) reduces 99.9% of bacteria, specifically MS2 Bacteriophage and Staphylococcus Aureus. The conditioning cycle helps to prolong life of the hearing aids, reduce service issues, and improve audio performance.

How does Dry & Store work?
Dry & Store dryers are low-power, electrical appliances (with the exception of the battery-powered DryCaddy UV), recommended for in-home use every night. All models include digital circuitry for precise timing and temperature control. Place your hearing aids in the drying compartment, press the POWER button, and Dry & Store does the rest. On models equipped with a UV-C lamp, for the first few minutes, an ultraviolet (UV-C) lamp sanitizes the hearing aids by reducing bacteria on the hearing aid. Then, for the next few* hours, Dry & Store gently circulates warm, dry air. If your Dry & Store appliance uses a desiccant, throughout the cycle, the desiccant captures the moisture molecules as they are released from the hearing aids and eliminates odors. The DryBoost UV, DryCaddy UV and DryKlean UV are convection dryers, meaning the moisture released from the hearing aids escapes through the holes in the appliance lid. All models have a built-in timer and will automatically turn off at the end of the cycle.

*Drying cycle varies by product. Refer to individual product information for drying time.

What if I have to use my hearing instruments before the cycle is finished?
While the best results will be achieved with a full cycle of conditioning, some of the benefit of Dry & Store conditioning can be gained by shorter cycles.

DryBoost UV, DryCaddy UV, DryMax UV, Global, Global II, Professional:
When you interrupt the process by opening the unit, the unit shuts off, and the timer re-sets itself, ready for the next full cycle.

DryDome, DryMax (non-UV), and Zephyr:
Press the POWER switch to interrupt the cycle then remove your hearing aids.

How warm does it get? Is it safe for ear molds and wax guards? What about the batteries?
The temperature inside Dry & Store is not much different from your body temperature. It is limited by a thermal control system, so you can safely place everything in the tray – hearing aids, earmolds, tubing, even the batteries. We do recommend the battery doors be open. NOTE: Rechargeable hearing aids must be dried at a lower temperature to avoid damage to the batteries. The DryBoost UV is made specifically for rechargeable devices using a lower temperature than the other Dry & Store appliances.

I can leave the batteries in?
Yes, you can leave the batteries in the hearing aids during conditioning, with the battery door open.

Does it work on noise maskers, ear monitors, ear buds, and cochlear implant speech processors?
Yes. Since moisture dampens the responsiveness of microphones and speakers, corrodes battery contacts, and interferes with conductivity of delicate electronics, any device that includes one or more of those components can benefit greatly from Dry & Store. Dry & Store also helps prevent corrosion of other components such as switches and hinges.
Behind-the ear and in-the-ear devices such as monitors and maskers, as well as ear-level speech processors, can be conditioned in any model. Dry & Store is also effective for drying and sanitizing ear buds that are used with portable music players.

Can I use Dry & Store with my rechargeable hearing aids?
Rechargeable hearing aids must be dried at a much lower temperature than regular hearing aids. Heat can damage the rechargeable batteries. DryBoost UV has a precisely controlled drying temperature that was designed specifically for use with rechargeable batteries. Read more.

Does the UV-C lamp heat the appliance?
No, the UV-C lamp used in equipped Dry & Store appliances generates very little heat. The air inside Dry & Store is warmed – and controlled – by a different mechanism. The UV-C lamp is on for a short time at the beginning of the conditioning cycle.
Back to Top


Does the UV-C lamp hasten hardening of BTE tubes? Can it cause damage or discoloration?
The Dry & Store UV-C lamp is a great surface sanitizer, but it has no penetrating power, and it does not generate damaging ozone. With tens of thousands of units in use, the UV-C cycle has not had a detrimental effect on tubing or molds. Tubing is often affected by climate conditions, body oils, hairsprays and similar products.

My hearing aids get clogged with earwax. Can Dry & Store help?
Yes. Earwax contains a certain amount of moisture. When that moisture is removed during Dry & Store conditioning, it becomes flaky and easier to remove from the instrument.

What is a desiccant and what does it do?
Desiccant is a term for a substance that captures moisture, either through absorption or adsorption (a specialized term in chemistry). The desiccant is a critical part of the Dry & Store conditioning process, because it captures the moisture released during the conditioning cycle. Without a desiccant, moisture would simply re-settle on and in the hearing aids at the end of the cycle.
The Dry-Brik II and Dry-Brik Mini desiccants used in Dry & Store, a powerful proprietary molecular sieve, is super efficient at capturing moisture, and it is also an effective deodorizing agent.

Do all Dry & Store appliances use the same desiccant?
No. While the same Dry-Brik II desiccant works in the Global, Global II, Professional, and Zephyr models, the DryMax and DryMax UV use the Dry-Brik Mini desiccant. The DryCaddy and DryCaddy UV utilize DryCaddy Discs. Dry-Brik II is replaced every two months. Dry-Brik Mini replacement is every month. DryCaddy Discs (one is replaced every two months; the UV version is replaced monthly.)

All of our desiccants use "molecular sieve," a premium sorbent which contains tiny pores of a precise and uniform size. It acts at a molecular level (hence the name) by allowing small molecules – such as water – to pass through, where they are retained within the pores. A molecular sieve can adsorb water up to 22% of its own weight, and it is especially effective when operating in a warm environment such as a Dry & Store appliance One of its important features is that once it grabs onto a moisture molecule, it holds it tightly so it's "gone for good."

How long does a Dry-Brik II last?
The Dry-Brik II is formulated to last two months. Dry-Brik Mini is replaced monthly. DryCaddy Discs (one is replaced every two months; the UV version is replaced monthly.)

Will the desiccant last longer if I remove it from the machine every morning and store it in a zip-lock baggie during the day?
No, for all that extra effort, you won't see any difference in the life of the desiccant. That's because when the Dry & Store lid or drawer is closed and it's not turned on, there's no air movement, and air is not being actively drawn into the closed unit. DO keep the lid/drawer closed at all times. DO keep the unit someplace other than extreme humid areas such as the bathroom.
