  • Dry Caddy Hearing Aid Dryer
Dry Caddy bridges the gap between doing nothing to maintain a hearing instrument and using an active drying system from Dry & Store. The Dry & Store Dry Caddy Hearing Aid Dryer uses a molecular sieve desiccant, the most powerful, most aggressive, and most effective desiccant on the market.

The Dry Caddy Hearing Aid Dryer is ideal for times when it's not convenient or practical to use an electronic Dry & Store system. Since it requires no electricity, take the Dry & Store Dry Caddy Hearing Aid Dryer to the pool or beach, even camping or short trips - the waterproof jar offers protection from the elements while refreshing hearing devices.

The Dry & Store Dry Caddy system comes with six specially designed Dry-Disc molecular sieve desiccants. Use a fresh Dry-Disc desiccant every two months for maximum drying performance, then simply order a new Dry Caddy kit after all the Dry-Discs have been used!

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.


  • No recharging or reactivating, no batteries no electricity
  • Powerful molecular sieve desiccant captures moisture and odors
  • Molecular sieve desiccant is safe - does not contain any hazardous chemicals
  • Each Dry-Disc desiccant is a single-use product capable of drying devices in the Dry Caddy for a period of two months, so the total drying time of a Dry Caddy kit is one year
  • Includes 1 Dry Caddy jar plus 6 Dry-Discs

    Product is complete and well made. It sets you up for a year and is well packaged and convenient to use. I will definitely be replacing it with the same product next year. (Posted on 7/20/2017)

  3. Still Reliable Review by EarlyRiser
    Overall Satisfaction

    This is my second time to purchase this product. In fact, two of my siblings recently purchased it again as well, after we purchased it in June, 2016. Delivery was prompt. Service has been hassle-free. We've enjoyed the simplicity and reliability of this product, just as I commented last year. Thank you, Harris! (Posted on 7/13/2017)

  4. Great item Review by Kathy

    This is the second dry caddy I've bought and I'm very pleased with it. Especially being encouraged to write the date. That helps a lot. (Posted on 12/27/2016)

  5. Repeat purchase Review by Kathy
    Overall Satisfaction

    This is a great product for keeping my hearing aids dry and stored, especially when I travel. I have recommended it to other hearing aid users as well. When you spend so much money on hearing instruments, it makes sense to try and preserve them as long as possible. (Posted on 12/14/2016)

    This is Great for what It does. It keeps the hearing aids nice and clean. (Posted on 8/18/2016)

  7. Easy and Effective Review by EarlyRiser
    Overall Satisfaction

    The video on the Harris Communications website convinced me to purchase this product over similar ones. I even bought one as gifts for my brother (hearing aid user) and sister (cochlear implant user) who are also very pleased with this. I appreciate the tip of putting the date on the disc t to help remind me when it to replace it. Thank you, Harris, for captioning the video, too! (Posted on 6/27/2016)

    I love it. This is great travel and more room in my suitcase. (Posted on 5/13/2015)

  11. Great product, no mess Review by Terost
    Overall Satisfaction

    No more taking the crystals to the microwave oven, then cooling the crystals for a while before it goes back to the glass container. This product is wonderful, no mess at all.

  12. Good Product Review by Sonja
    Overall Satisfaction

    I like this product mostly because I don't have to worry about the crystals anymore because the last time I had to put them in the microwave, they burned; plastic and crystal, I just replace the green pod after two months with another. I also thought six pods was reasonable for the price charged. It seems to work well and my aids are protected in the plastic case too. (Posted on 7/28/2014)

  13. Very well please with product. Review by Gene
    Overall Satisfaction

    First time I have every seen or heard of this product. It is very easy to use and to tell someone (disable person) to show and them able to use it. Will see if the people that service the hearing aide thinks it working. Thanks for the product. (Posted on 5/12/2014)

  14. Great product. Review by Mark
    Overall Satisfaction

    I use it for my behind the ear hearing aids and this product works better than any other I have tried. The case is also perfect for travel. (Posted on 4/2/2014)
