Oasis Guitar Humidifier OH-1

When winter arrives it’s time to put your Oasis Guitar Humidifier to work!

For complete confidence that your guitar is getting the humidification it needs in dry seasons without worrying about your humidifier leaking or hurting your instrument, check out the original blue Oasis Guitar Humidifier OH-1. 

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.

 

Your Instrument Can Crack In Dry Weather

You probably already know that your instrument can crack in dry weather. Repairing a cracked top of a fine guitar is both expensive and can alter the sound of your instrument. To solve this problem, guitarists have been using guitar humidifiers since the 1960’s. These humidifiers often have a number of drawbacks. The first is that you cannot see when they need to be refilled. When you do refill them, they can be overfilled and drip inside your instrument. This is because most currently available humidifiers have openings to allow for water evaporation. The job of protecting the instrument against leaks is left to an absorbent medium such as a sponge or floral foam, which can be over saturated with water.

The Oasis Guitar Humidifier OH-1 has solved these problems by using a completely different approach. The body of Oasis 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. By watching the Oasis shrink, you can determine when it is ready for refill. When refilling, 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, are 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 instrument. The materials that touch your strings are relatively soft and will not scratch your strings. 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. Oasis never touches the body of your instrument!

 


How To Fill Your Oasis

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:  Oasis 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.
