Get the most out of your hearing aid or listening device investment with PerfectDry! PerfectDry is the most affordable hearing device dryer in our lineup, yet still manages to complete a full drying cycle in just 2 hr 15 min (135 min). It uses automatic temperature regulation, a hot air diffusion system, and natural convection to remove sweat & moisture from your device efficiently & affordably. The automatic temperature regulation limits the maximum temperature to 104F, making PerfectDry completely safe to use with both non-rechargeable AND rechargeable hearing aids, Airpods, earbuds, in-ear monitors, electronic hearing protection devices, and cochlear implants. Other products with a higher maximum temperature can damage your hearing devices and/or batteries. For a tiny fraction of the price of your hearing device, you can prolong its life, improve its performance, and reduce the chances you will need costly repairs. PerfectDry is an electronic dehumidifier that's large enough to accommodate 2 behind-the-ear (BTE) hearing aids, 2 in-the-ear (ITE) hearing aids, or 2 cochlear implants. Also serves as a perfect storage case, or carrying case when you're traveling or on-the-go. Use daily for best results.
