Oasis guitar soundhole humidifier Blue, for normal dryness (25%-40% ) environments

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 cant. Oasis is simply the best guitar humidifier on the market because it:

Makes it easy to see when its 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. To solve this problem, guitarists have been using "sound hole" humidifiers since the 1960's. These humidifiers have significant shortcomings. You cant see when they need to be refilled, and when you do refill them, they can be overfilled and drip inside your expensive instrument. This is because all currently available "sound hole" humidifiers have openings to allow for water evaporation. The job of protecting your guitar against leaks is left to an absorbent medium like a sponge or floral foam, which can be easily over saturated with water.

Oasis has developed a better answer to humidification and solved these problems by using a completely different approach. 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, its 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 wont scratch. A blue 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.

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.

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.
