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.

Have a flat top case? Here's a suggestion from another guitarist.


Kevin S. Hart

Living at 7,200 feet, with a yearly average humidity of 20%, I am familiar with just about every humidifier on the market. The Oasis is the best that I have come across. The Oasis humidifies longer and at a more reliable rate than others I have tried, there is never any question about when to refill, and the process is quick, easy and neat. Combined with the humidifier never leaking or coming in contact with the instrument, the result is an efficient and elegant solution to guitar care in a harsh environment.

Because tap and bottled water have dissolved minerals that can clog the liner, distilled water is recommended to extend the useful life of your humidifier.
