The huge success of our original blue Oasis® “sound-hole” Guitar Humidifier brought numerous inquiries about how to provide humidification for other wooden instruments such as violins, violas, cellos, jazz guitars, and some woodwind instruments like clarinets and oboes. After careful consideration and research, we developed the OH-6 Case Humidifier. This style of Oasis® humidifier attaches to the inside of your instrument case. To accomplish this, two powerful neodymium magnets are inserted in the seam of the humidifier. The magnets attach to either a steel clip or a stainless steel strip with adhesive backing (both are provided with the humidifier). The steel clip fits over the side of your case, providing a flat vertical surface to which the magnets can adhere. The neodymium magnets are strong enough to keep the humidifier attached to the clip or strip, but still allow the user to remove the humidifier with ease.
The OH-6 Case humidifier can be used to humidify the headstock of a guitar by attaching the clip over the backside of the case. The humidifier can also be used in stringed instrument cases such as violin, viola or cello by attaching the stainless steel strip to the inside of the instrument case with the double sided tape. The steel clip and strip give the user a wide variety of ways to attach the humidifier to the case. Like all of our humidifiers, we provide 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.
