Description Additional Information About HearUSA
Dry Caddy Hearing Aid Dehumidifier, a passive (non-electric) dehumidifier from Dry & Store

Dry & Store, the worldwide leader in electric hearing dehumidifiers introduces the next best thing in a ‘passive’ dehumidifier. While more affordable than the fan type dehumidifiers, the Dry Caddy provides optimal care for hearing devices. Because all deaf technology devices require special care and maintenance to prevent the inevitable damaging effects of moisture in both short-term and long-term performance, an efficient hearing aid dehumidifier is essential, Dry Caddy brings passive dehumidification to a whole new level.

  • Easy to use & portable
  • An entire year of protection in one small package
  • No recharging or reactivating, no batteries, no electricity
  • Dry-Disc™ – powerful molecular sieve desiccant captures moisture & odor
  • Change Dry-Disc every 2 months for maximum drying performance
  • Includes: (1) Dry Caddy Jar & (6) Dry-Discs

Dry Caddy uses the most powerfull, most aggressive and most effective desiccant on the marketmolecular sieve. It out-performs the more commonly used silica gel desiccant an all categories with respect to the are of delicate hearing instruments and other assistive devices for the deaf.

The desiccant material is safe and does not contain any hazardous chemicals. Using a fresh DryCaddyt Disc (DC disc) desiccant every two months ensures that the DC Disc performs properly

Dry Caddy is also a handy alternative for those times when it’s not convenient or practical to use an electronic Dry & Store system, such as when camping or even for short trips. It’s perfect for outings to the pool or beach, because it requires no electricity, and the waterproof jar offers protection from the elements while refreshing hearing devices.

How to use the Dry Caddy

Molecular sieve desiccant

Compared to other common desiccants such as silica gel, a molecular sieve desiccant is best at removing even the most tightly bound moisture from the tiny crevices, pores, openings, and tubes of hearing devices as well as other moisture-sensitive devices. Once the moisture has been pulled from the device to the mol sieve, the mol sieve continues to aggressively hold onto the moisture with very strong electrostatic bonding forces.

Adsorption is the binding of molecules or particles to a surface. You may see charts comparing adsorption capacities of various desiccant types, showing silica gel having a slightly greater surface area. However, the difference in surface area is very slight. Both desiccant types have a huge amount of surface area on their crystalline structures. Second, adsorption capacity is affected by humidity. The mol sieve has greater capacity than silica gels at relative humidity levels below 40%, which is the typical condition inside a drying device, whether passive or active. Third, the most important factor is how quickly the water molecule is attracted to the desiccant and how well molecules "stick" to the surface. Think of silica gel as a sticky note and molecular sieve as duct tape.

Recharging desiccants

The strong electrostatic bonding forces between polarizable water molecules and the surface of the molecular sieve crystals make mol sieve by far the best desiccant for hearing device drying. However, it is that moisture-bonding strength that also makes it difficult to reactivate for multiple use. The high temperatures required for thorough reactivation of a mol sieve desiccant would cause the plastic Dry-Disc desiccant container to melt before the mol sieve is properly reactivated. Even silica gel desiccants cannot be recharged an indefinite number of times because the silica gel's structure changes to the point that it does not attract or hold moisture. Overall, recharging simply is not a reliable process.

Dry-Disc and Dry-Brik desiccants

Dry-Disc and Dry-Brik desiccants are not interchangeable. The Dry-Brik should not be used in the Dry Caddy Hearing Aid Dryer system. The rate of adsorption is regulated by the number of holes in the desiccant container. The Dry-Brik desiccant has four tiny holes for use in an active drying system while the Dry-Disc desiccant has dozens of tiny holes in order to facilitate the movement of moisture to the desiccant in a closed passive drying system (the Dry Caddy jar) with no air movement.
