The Oasis Case Plus+ Humidifier uses the same evaporative membrane as the Oasis Plus+ Humidifier, providing 50% more daily humidity than the Oasis Case Humidifier.

This humidifier is designed for use in drier environments where the relative humidity is below 25%. The Oasis Case Plus+ humidifier, like the Oasis Case Humidifier, uses a small but powerful magnet, which is embedded in the seam of the humidifier, to attach to either a small sticky-backed piece of stainless steel or a metal clip (both are provided with the humidifier).

The Oasis Case Plus+ Humidifier can be used in stringed instrument cases such as violin, viola cello, guitar, or mandolin.

Oasis' case style humidifiers attach to the inside of your instrument case. They give you the same reliability and ease of use as our original humidifiers, outperforming other case and instrument humidifiers by doing the following:
• Making it easy to see when it’s time to refill.
• Providing long-lasting humidification.
• Ensuring no leakage due to overfilling.
• Promising two levels of leak protection.

How does it work? A neodymium magnet* in the humidifier enables you securely attach it inside your case, while still being able to easily remove and re-attach it to either a steel belt-style clip or a stainless steel strip with adhesive backing (both are provided with the humidifier). The belt-style clip fits over the side of your case, providing a flat vertical surface to which the magnet can adhere. The adhesive-backed stainless steel strip allows for either vertical or horizontal attachment anywhere there is a flat surface inside the case.** This type of humidifier provides the flexibility to position the humidifier in a wide variety of locations within your instrument case.

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