ALDS #1 Selling Hearing Aid Dry & Store Unit
Dry & Store is an electrical appliance for nightly use at home to store and care for all types of hearing instruments, including hearing aids, cochlear implant hardware, noise/tinnitus maskers, and in-ear monitors.
It combines the three essential elements needed for effective drying: heat, moving air, and a desiccant that drives the relative humidity really low, and captures the moisture that is released.
During the first ninety seconds of the Dry & Store Global II cycle, a germicidal lamp sanitizes the hearing instruments, after which conditioning continues for 8 hours. The unit then automatically shuts off, continuing to store the instruments safely until they are needed.
After pressing the ON button, Dry & Store Global II will run for 8 hours before automatically turning off. However, if the lid is opened before the 8-hour cycle is complete, the unit turns off and the electronics timer resets itself.
In most locations around the world, the Global II ships with the custom Dry-Brik® II desiccant. The Dry-Brik contains an aggressive sorbent (mol sieve) packaged in an attractive, molded, disposable container. Each Dry-Brik has a shelf-life of at least one year, unopened. Once the foil label is removed, the Dry-Brik II lasts two (2) months. Replacement desiccants are inexpensive and are available from Dry & Store distributors. The desiccant also absorbs odors as it dries. In some countries the Global II ships with an oven rechargeable metal dry can. Both types of desiccants are available as accessories, and Dry & Store Global II operates well with either, though a can-type does not provide the deodorizing function that the Dry-Brik provides.
The Dry & Store germicidal lamp is a short wave low pressure mercury vapor tube that produces ultraviolet (UV-C) wavelengths that are lethal to micro-organisms. During its one-and-a-half minute cycle, just 90 seconds, the lamp will generate enough germicidal energy to yield a 99% kill on common bacteria found in the external ear canal.
- 4 watts UV-C (@ 254nm, which is the peak germicidal wavelength) in the Global II model produces
over 400 joules/m2 of UV-C energy.
- For comparison purposes, a 90% kill on staphylococcus aureus bacteria requires only 26 j/m2.
Elimination of this flora from hearing aids can significantly reduce itching and the reintroduction of infection-causing bacteria into the ear canal. To the user, this means less itching and irritation, and fewer recurring infections of the external ear canal. Note: The UV-C lamp is a surface sanitizer only, and it has little to no penetrating power. This means that it is not damaging to plastics or earmolds. (Germicidal lamps are not to be confused with sunlamps or blacklight lamps, for while those are also ultraviolet lamps, the UV produced by a sunlamp or blacklight is of longer wavelength and is not useful for germicidal applications.)
Batteries do not have to be removed from hearing aids before Dry & Store use. Independent tests by Eveready Battery Co. on their Energizer/Amplifier® batteries showed a 10-20% gain in battery life under high (85% RH) humidity conditions and no decrease in life at normal (50% RH) conditions. This was confirmed by a user survey which showed that over 50% of users experienced longer battery life.
