Oasis Guitar Soundhole Humidifier Yellow Plus OAS/OH-5

Guitar soundhole humidifier Yellow Plus+, for very dry (below 25%) environments
While the original Blue Oasis provides sufficient humidity in many environments, it is not effective everywhere. The humidity demands of the desert, mountain states or frigid north exceed the humidification capacity of the device. For this reason, we have developed the Oasis Plus+ humidifier. The Plus+ is the same size and shape as the original blue Oasis, but is made of a different material which provides 50% more humidity output.

Because the Oasis Plus+ HumidifierPlus+ is the same size as the original Blue Oasis and it has 50% greater humidity output, it will be necessary to refill the Oasis Plus+ more frequently than the original Blue Oasis.

If one is using a hygrometer, we recommend that the Oasis Plus+ be used when the room humidity is below 25%. The original Blue Oasis should be used when the surrounding room humidity is between 25-40%. Above, 40%, you should not be using a humidifier.

It is important to also to monitor the humidity inside your instrument case. Case size, design, material and other factors will impact the humidity permeability of each case. While general rules are helpful, a good hygrometer located inside the instrument case will give you the best information regarding proper humidification requirements.

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.
