General Questions



Why do you call it a conditioning system ?


Because Dry & Store is not simply a dryer, and moisture removal is just one of its many benefits. Dry & Store also dries cerumen for easier removal from hearing aids, and it deodorizes the hearing aids. A germicidal lamp (included in the Professional, Global, and Global II models only) kills 99.9% of bacteria and other organisms that if not removed can cause itching, irritation, or recurring infections. You can expect improved clarity and dependability, longer-lasting batteries, fresh and clean hearing aids, and for many people, an end to itching and irritated ears.

How does it work?


Dry & Store units are low-power, electrical appliances, recommended for in-home use every night. Place your hearing aids inside, press the start button, and Dry & Store does the rest. For the first few minutes, an ultraviolet lamp sanitizes the hearing aids by killing resident bacteria. Then for the next eight hours, Dry & Store gently circulates warm, dry air. Throughout the cycle, the desiccant captures the moisture molecules as they are released from the hearing aids. Dry & Store has a built-in timer and will turn itself off after approximately eight hours.

What if I have to use my hearing aids before the 8-hour cycle is finished?


Just open the drawer (or on the Global and Zephyr models, lift the lid) to interrupt the cycle. While the best results will be achieved with the full 8 hours of conditioning, some of the benefit of Dry & Store conditioning can be gained by shorter cycles. When you interrupt the process by opening the drawer (or lifting the lid), the unit’s timer re-sets itself*, ready for the next full cycle. Just press the Start button when you're ready to start a new cycle. *Note: the Zephyr timer does not reset itself when you open the lid. Instead, it continues the cycle underway until the ON/OFF button on the side of the unit is pressed.

How warm does it get? Is it safe for ear molds and wax guards? What about the batteries?


The temperature inside the unit is close to your body temperature. It is controlled by a sophisticated electronic thermal control system, so you can safely place everything in the drawer - hearing aids, earmolds, tubing, even the batteries.
Back to Top


I can leave the batteries in?


Yes, you can leave the batteries in the hearing aids during conditioning, with the battery door open. As noted above, the temperature is a controlled warmth – it's not "cooking" anything.

In fact, Dry & Store conditioning can actually prolong the life of zinc air batteries. Independent testing by Energizer revealed that in high humidity conditions, Dry & Store increased the life of their zinc air batteries by 10 - 20%. Another reason for batteries lasting longer is that Dry & Store can improve a hearing aid’s efficiency. Simply put, it takes less energy to power a hearing aid that is completely dry.
Back to Top


Does it work on other devices such as cochlear implant equipment, noise maskers, ear monitors, etc.?


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. Body-worn processors require more room than the Professional model provides, so the Global, Global II, or Zephyr would be better choices.
Back to Top


How does Dry & Store relieve itching or irritated ears?


Dry & Store Professional, Global, and Global II units utilize a highly specialized ultraviolet (UV-C) germicidal lamp that operates at the beginning of the conditioning cycle. During this brief period, the lamp generates enough germicidal energy to kill 99.9% of the bacteria that are a common cause of itching ears. (Note that the only function of the UV lamp is to kill germs; it does not heat the unit. The unit is heated by other mechanisms that precisely control the heat.) The Zephyr does not contain a UV lamp but does provide the same drying benefit as its larger siblings, the Professional and Global models.
Back to Top


Does the UV lamp heat the appliance?


At 4 watts, the UV-C lamp used in Dry & Store generates very little heat. The air inside Dry & Store is warmed - and controlled - by a different mechanism. The UV lamp is on for just a few minutes at the beginning of the 8-hour conditioning cycle.
Back to Top


Does the UV lamp hasten hardening of BTE tubes? Can it cause damage or discoloration?


At 4 watts, the Dry & Store 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 germicidal 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 moisture. When that moisture is removed during Dry & Store conditioning, it becomes flakey and thus easier to remove. In a nationwide survey, 100% of hearing healthcare professionals recognized Dry & Store as an effective cerumen management tool.
Back to Top


What is a desiccant and what does it do?


Desiccant is a term for a substance that captures moisture, either through absorption or ad sorption (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 8-hour 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 desiccant used in Dry & Store, a molecular sieve, is super efficient at capturing moisture, and it is also a highly effective deodorizing agent.
Back to Top


Do all Dry & Store appliances use the same desiccant?


Yes. The same Dry-Brik works in the Professional, Global, Global II, and Zephyr models. Alternatively, the Global and Zephyr models can also use a rechargeable metal can desiccant, according to personal preference. Please note, however, that a metal can does not provide the deodorizing function, and due to the amount of moisture being moved to the desiccant during Dry & Store conditioning, a can desiccant will require more frequent re-charging than is common when used with a pouch or jar.

The Dry-Brik II is a superior product based on the physical characteristics of its active ingredients. The Dry-Brik II uses a "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 or Zephyr. One of its important features is that once it grabs onto a moisture molecule, it holds it tightly so it's "gone for good."

The canister desiccant's ingredient, silica gel, is an inexpensive, man-made, solid substance with a high surface area but no uniform porosity. Ease of regeneration makes it suitable for users in areas where Dry-Briks are not available or for individuals who choose to not use consumables. Silica gel is most effective at room temperature, and its capacity declines as it is heated. It will not adsorb the same amount of water as molecular sieve, but since it can be easily regenerated in a conventional oven (no microwaves!), this is typically not an issue for most users.

How long does a Dry-Brik last?


The Dry-Brik II is formulated to last two months even in highly humid climates.

Back to Top


Will the Dry-Brik 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 Dry-Brik. 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 drawer closed during the daytime. DO keep the unit someplace other than extreme humid areas such as the bathroom. The manufacturer of the new Dry-Brik II guarantees that it will adsorb moisture for two (2) months.
Back to Top


Is there a different lifespan for the new Dry-Brik II between summer and winter months?


There could be a slight difference, depending on where you live. If you live in a climate where you have a lot of rain, you definitely want to stick to the two-month schedule. If you live in a climate where you have the heat on in your house for several months and it tends to be dry, the Dry-Brik could last a bit longer. Of course if you're outside shoveling snow and working up a sweat, you're still accumulating moisture in your hearing instrument, and the Dry-Brik will be "on duty" to adsorb it.

Overall, the difference is not significant over the span of a year, so it's a good idea to get in the habit of changing the Dry-Brik every two months in order to ensure that you have a fresh, charged desiccant at all times. If you change your Dry-Brik II every two months, the average cost will be around $2.00 a month to keep your hearing instruments working at their peak performance.
Back to Top


Can the Dry-Brik be recharged?


No. The Dry-Brik is not rechargeable. the temperature required to break the polar bond between the adsorbed moisture and the pores of the sorbent material is far too high and would melt the plastic.
You can dispose of used Dry-Briks in regular household trash. The plastics used in a single Dry-Brik II weigh about 0.1 ounces. Over a five-year period, the average user will go through only 3 oz of polypropylene. The desiccant itself is a clay-based product, so it is inert. We recommend against trying to separate the plastic from the desiccant for recycling purposes.
Back to Top


Can I use a rechargeable metal can desiccant?


The Global model will work with either the Dry-Brik or a traditional metal can desiccant. (The Professional model works with the Dry-Brik only.)

Routine recharging of a metal can desiccant is required. As moisture is adsorbed by the desiccant, the crystals will change from blue to light pink, or from orange to pale, depending which desiccant you have. A light pink or pale orange color signals that the desiccant can no longer absorb moisture. Proper function can be restored by placing the metal desiccant can in an oven for 2 hours or more at a temperature of 105¡-150¡C (225¡- 300¡F). The color will change back to blue or bright orange. Repeat as necessary.

The metal canister will be hot when it is removed from the oven, so caution should be used to avoid burns. Allow the can to cool before it is placed in Dry & Store. Best results will occur if the can is covered during the cooling period; a drinking glass or pan lid works well.
WARNING: Use care when removing the metal desiccant can from the oven. Allow it to cool before handling. Never place metal in a microwave oven!

The frequency of metal can desiccant recharging will vary according to several factors, such as season, geographic location, local climate/weather conditions, and the activity/perspiration level of the user.

Check the color of the desiccant crystals before each use, and recharge as needed. Whichever model of Dry & Store you use, and whichever type of desiccant you choose, do not operate Dry & Store without a properly positioned desiccant.
