Oasis UKulele Plus Soundhole Humidifier OAS/OH-32

Ukulele Plus+ soundhole humidifier, for very dry (below 25%) environments
The OH-32 humidifier is designed especially for your ukulele. It has a mounting system that allows the humidifier to hang horizontally inside the ukulele rather than vertical (like the guitar humidifier).
If you are located in an extremely dry climate (20-25% RH), the OH-18 Ukulele humidifier may not provide sufficient humidity. If that is your situation, the OH-32 will do the job. It is the same as our OH-5, but comes with the ukulele stabilizer bar rather than a guitar stabilizer bar.
The exclusive Oasis design of all our humidifiers makes the Oasis Ukulele Humidifier easy to see when to refill, provides long-lasting humidification, ensures no leakage due to overfilling, and promises two levels of leak protection.
Because tap and bottled water have dissolved minerals that can clog the liner, distilled water is recommended to extend the useful life of your ukulele humidifier.
Most instruments only need seasonal humidification. Typically, the humidity drops in the fall and rises in the spring. When the spring arrives, we recommend that you remove the humidifier, wash all of the crystals out, and leave the cap loosely on the humidifier. If you do not remove the crystals and loosen the cap, the humidifier will shrink up, dry up and the crystals will stick together. In the fall, it is easy to damage the lining of the humidifier when trying to restore it to shape. The lining is only 1/1000th of an inch thick and can be damaged easily if it sticks to itself and the crystals, when the humidifier shrinks up and dries up if the lid is left on tight.
