For complete confidence that your guitar is getting the humidification it needs in dry winter weather without worrying about whether your humidifier is leaking or hurting your instrument, check out the original Oasis® Guitar Humidifier.

Effective and reliable, it does what others can't. Oasis® is simply the best guitar humidifier on the market because it makes it easy to see when it's time to refill. Provides long-lasting humidification. Ensures no leakage due to overfilling. Promises two levels of leak protection. Is stabilized to never touch the body of your instrument. You already know that your instrument can crack in dry weather. But, do you know how to protect it? Repairing a cracked top of a fine guitar is expensive, and it can alter its sound.  Oasis® has developed a better answer to humidification: The body of the Oasis® Guitar Humidifier is made from a specially designed fabric that allows water vapor, but not water, to pass through it. As the vapor transmission takes place, a vacuum is created and Oasis® shrinks to compensate for the loss of water. Because you can see the Oasis® shrink, it's easy to determine when it is ready for refill.

Also, you don't have to guess when it is full. Simply unscrew the black cap, fill with water to the top of the container, and replace the cap. Once sealed, the water-tight container is your first line of defense against leaks. Humigel, the super absorbent polymer crystals inside Oasis®, is your second line of defense. Humigel captures up to 500 times its weight in water in an absorbent gel matrix. Like other "sound hole" humidifiers, Oasis® fits between the strings of your guitar. The materials that touch your strings are relatively soft and won?t scratch. A polyurethane stabilizing bar fits over the neck of the humidifier. Once positioned in the sound hole, the stabilizing bar lies across the guitar strings to ensure even weight distribution. The Oasis® Guitar Humidifier never touches the body of your instrument. 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.
