How the Oasis OH5 Plus+ Protects Your Guitar

Oasis OH-5 Plus+ Guitar Humidifier Installed in the SoundholeWhen mounted between the D and G strings in your guitar’s soundhole, the USA-made Oasis OH5 Plus+ Guitar Humidifier protects your instrument against hairline cracks that might result from drying out. What sets the OH5 Plus+ apart from many other soundhole-mounted humidifiers is its elegant anti-leakage design. Soundhole humidifiers that use foam or sponge to hold water may provide adequate defense against dry environments, but fail to protect the instruments from potential leakage from the humidifiers themselves. The Oasis OH5 Plus+ prevents water leaking into your guitar in two ways:

  1. The OH5 Plus+ reservoir is made from a specially designed fabric that allows vapor to pass through it and humidify your guitar while blocking the passage of water.
  2. The super absorbent Humigel crystals inside the OH5 turn water into jelly. This enables the water to evaporate and humidify your instrument, but prevents water leaks should the humidifier become damaged.

To further protect your instrument, the Oasis OH5 Plus+ is made from soft materials so it will NOT damage your strings or dent or scratch your guitar.

As water vapor is dispensed from the OH5 Plus+, the humidifier shrinks, making it easy to tell when it needs a refill. The included 10cc syringe makes filling the humidifier a snap. As the minerals contained in tap or bottled water may clog the liner, distilled water is recommended to extend the life of the humidifier.

When Should You Use the Oasis OH5 Plus+?

Using a specially designed evaporative membrane to maximize humidification, the Oasis OH5 Plus+ humidifier is suitable for extremely dry environments with humidity levels below 25%. If your room is moderately dry, with its typical humidity between 25% and 40%, we recommend the Blue Oasis OH1 model instead. In conditions above 40% humidity, you should NOT use a humidifier at all. Typically, humidity drops in the fall and rises in the spring, so you may not need to humidify your guitar all year round, or you may switch between the OH5 and OH1 models as needed. It’s best to use hygrometers to determine the exact humidity levels both inside and outside your guitar case.
