Best Guitar Humidifier

The biggest environmental enemy to a solid-wood acoustic guitar is low relative humidity. If the wood in your guitar dries out, you’re going to have problems. The good news is, the problems can be alleviated, and often remedied by using a best guitar humidifier. And, if you use a guitar humidifier during dry seasons, your guitar will stay properly humidified.

Do you need a humidifier for your guitar? You may need a guitar humidifier if…

  • You have an acoustic guitar made of solid wood. Laminate-top guitars do not require humidifiers.
  • You live in a dry, desert area.
  • You have cold winters and heat your home with dry-air heating.

You’ll Need a Guitar Humidifier if Your Guitar Has These Symptoms

How can you tell if your guitar may be dried out? It will have any of the following symptoms:

  • The fingerboard shrinks, causing the sharp ends of the frets to extend beyond the edge of the neck.
  • The arch in the top sinks and so does the bridge.
  • The neck bows forward, requiring a truss rod adjustment.
  • There’s a hump around the 14th fret.
  • Strings buzz at high notes

If your guitar shows any of these symptoms, get a sound-hole humidifier into your guitar and put your guitar back in its case. It may take a few days but the symptoms will likely go away.

The Blue Oasis Guitar Humidifier is made from a specially designed fabric that allows water vapor (but not water) to pass through it. As water evaporates, the Oasis shrinks to compensate for the loss of water. By monitoring the shrinkage, you will know when it’s time to refill.

Refilling is easy. Unscrew the cap, fill with tap water to the top of the container and replace the cap. The watertight container combined with the super absorbent polymer crystals inside the Oasis Humidifier make the OH-1 leak proof.

Oasis fits between the guitar strings. The materials that touch your strings are soft and will not scratch your strings. A polyurethane stabilizing bar fits over the neck of the guitar humidifier. Once positioned in the sound hole, the bar ensures even weight distribution. Oasis never touches the body of your guitar.

The Oasis provides humidification for 7-10 days before needing a refill.


  • You can see when Oasis is ready for refill.
  • Long lasting humidification.
  • Won’t leak due to overfilling.
