Engineered with non-toxic crystallized desiccant technology, the Eva-Dry mini dehumidifier will quickly and efficiently absorb up to 4 to 6 oz of moisture from the air, without any leaks or spills. As the device absorbs the humidity, our moisture indicator beads will turn from orange to green, indicating that it's time to renew the unit for 10-12 hours. Repeat the process for up to 10 years!
