Humidifiers and Hygrometers : The Practice Page

Humidifiers and Hygrometers

by Kevin Hart on 03/06/18

In dry climates or dry times of year, it’s important to keep our guitars hydrated.

There are a number of products available to help us in this important pursuit. We’ll look at a few of them in this post. We will also discuss a few good practices to follow.

Room Humidifiers

Keeping the room that you store your guitars and practice in is important. They come in a variety of sizes and price points. Look for the one that will humidify the square footage that you have. Keeping house plants or even open bowls of water can help in smaller areas, too.

Guitar stands or wall hangers are convenient, but should only be used temporarily. The best place for your guitar, while not in use, is in the case.

Instrument and Case Humidifiers

There are a great number of instrument and case humidifiers available. These are usually tubes of rubber, plastic, or fiber containing something to hold water, such as sponges, gels, or saturated salt packages. Sponge types in rubber tubes can come in contact with the interior of the guitar and cause damage. Hard plastic cases can be accidentally dropped and dent or crack the top of the instrument. Gel filled fiber tubes are easy to use and tell you by their shrinkage when they need to be refilled. Saturated salt packs are more expensive, but keep the relative humidity at just about 50% exactly (where your guitar is happiest) and avoid the problem of over humidifying, as well.


Having a hygrometer is a good idea to see if a humidifier is needed and to make sure that the humidifier is working properly. Hygrometers range from simple dials to digital to Bluetooth enabled units that communicate with your smartphone. One thing to keep in mind about hygrometers is that they all have some degree of error and need to be regularly calibrated. Hygrometer calibration kits are relatively inexpensive and easy to use.

So, keep those guitars (and yourselves!) hydrated and happy practicing!
