Guitar Humidifiers: Hot Buying Secrets

Musicians use guitar humidifiers to prevent acoustic guitars from cracking due to dryness. They are useful if you live in locations with low humidity, or if you need to travel frequently.

In this article, I make a comparative review of guitar humidifiers available on the market.

The Need for Humidifiers

Dry weather and dry environments can cause irreparable damage to acoustic guitars. The contact with dry weather can end up, for the guitar, in the form of visible cracks in the wood.

One way to supply additional humidity to your guitar is through a device known as a guitar humidifier.

Designers created these devices to slowly release humidity inside the guitar through the sound-hole.

Sound-hole humidifiers all utilize some type of water reservoir with an absorbent medium. These absorbents can be made of common material such as:

  • a sponge,
  • water absorbent floral foam or
  • absorbent polymer.

Oasis Humidifier: Physical Installation

blankThe Oasis Humidifier is a product that has helped many guitar players with maintaining proper humidity.

It is easy to use, and it doesn’t cost much.

blankIn their models, the medium used by the humidifier is surrounded by some type of cover which holds the water absorbent medium in place. The cover also restricts the flow of water evaporation from the medium.

To get the humidity inside your guitar, they slip between your guitar strings and are held in place there. Depending upon the brand of humidifier you purchase, it may or may not touch the wood inside your guitar.

  • Dampit has designed a humidifier that lies inside your guitar, while
  • The product is completely suspended from the strings in the Oasis models.

Water Refill

blankWater holding capacity and the restrictiveness of the outer cover are the greatest factors in determining how often you will need to refill the device.

Needless to say, you can’t stick a quarter container of water inside your guitar. Despite this, there are several humidifiers that will hold an ounce (30 ccís) or more such as Oasis or Planet Waves.

Remember that, if your guitar needs several cc’s per day of water vapor, you will need to refill a humidifier that holds only 5-10 cc’s every few days. This is the standard mode of operation.

Water Vapor

blankPlanet Waves and Dampit utilize holes in the outside membrane to release water vapor. Oasis uses a fabric which allows the water vapor, but not the water, to pass through the material to keep your guitar humidified.

One downside of evaporation holes is the risk of water leakage. Very careful handling can minimize, but not eliminate this risk. Oasis is a water-tight, sealed unit which eliminates the risk of water leakage.

Refilling the Guitar Humidifier

The right moment to refill your guitar humidifier is one of the great mysteries… But the Oasis company solved this problem with their product. 

Since Oasis is a flexible sealed container, it shrinks as the water inside of it evaporates through the fabric.

When Oasis begins to look like a prune, you need to refill it…

As with any new product or service you purchase, please read the directions carefully before use.
