Guitar Humidifier to sound hole

For complete confidence that your guitar is getting the humidification it needs in dry seasons without worrying about your humidfier leaking or hurting your instrument, check out the original blue Oasis® guitar humidifier. The OH-1 guitar humidifier is a soundhole humidifier designed to maintain 45-55% relative humidity inside the guitar body when the humidity outside the case is between 25-40%, provided that the guitar is already hydrated. The OH-1 is not designed to restore humidity to a dried out guitar. The OH-1 is our most popular model. Each Oasis® OH-1 comes with a stabilizer bar for mounting the humidifier and a 10 cc. syringe for distilled water filling control.

Please Read Before Filling Oasis®

Handling your new Oasis® humidifier is simple, but it helps to know a few important things before starting.

Don’t dump out the crystals
There is a very small quantity of Humigel™ crystals, a dry, super water absorbent polymer, in every humidifier (.6 ccs). In most cases, you can shake the humidifier and hear them rattle around. Some users hear the rattling, open the cap and mistakenly dump them out. If you do this, you will need to purchase a Humigel™ replacement kit.

Hold Oasis by the yellow ends
Always hold the Oasis® humidifier by the yellow or brown ends rather than the fabric in the middle. The ends are rigid plastic which supports the structure of the humidifier. The middle blue or khaki section is soft squeezable fabric where water vapor escapes. If you squeeze the center while the cap is off the humidifier, Oasis® will behave like a toothpaste tube and eject the water and crystals. If you do this, you will need to purchase a Humigel™ replacement kit.

Fill Oasis® slowly
Oasis® typically holds slightly more than one ounce of water. When filling your Oasis® for the first time, the crystals will need a few minutes to absorb the water. If you try to fill the humidifier too quickly, it is easy to put in more water than it can hold. The crystals can be washed out with too much water. So, we recommend limiting the amount of water you initially put into the humidifier to 3 full syringes (10 cc’s each) and filling the humidifier slowly, giving the crystals time to absorb the water. We strongly recommend that you only use distilled water. Tap water contains minerals which will clog the Oasis® membrane over time. Watch carefully, and stop filling when the water reaches the top. After the initial filling of your Oasis® you will need to recharge the humidifier once a week with 7-10 cc’s of distilled water.

Sometimes, Humigel™ crystals may stick near the opening of the tube making it difficult to refill the device. If this happens, first bring the humidifier back to its original shape by gently holding the two yellow ends and pulling them away from each other. Secondly, hold the bottom yellow end, and gently tap your Oasis® on a hard service. This will knock the crystals loose to fall back towards the center of the humidifier. Then, proceed with refilling.

Spread the strings
Our soundhole humidifiers are designed to be installed and removed after the user spreads the strings. Since the humidifier is wider than the strings, installing or removing it without spreading the strings will damage the fabric on the humidifier and lead to premature failure of the humidifier.
