Best Guitar Humidifier

If you’re a new guitarist or beginning guitar lessons, you may not be familiar with guitar humidifiers and their importance in maintaining your instrument’s condition. When you store your guitar in your living room, in a guitar case, or particular storage space, the humidity levels contribute to your guitar’s performance and sound quality. That’s where guitar humidifiers come in. In this article, let’s look at the best guitar humidifier you can find on the market.

Humidity levels vary drastically depending on where you store your guitar, whether in a space with normal or relative humidity, dry, arid space in an attic, or a damp environment, such as a basement.

When your guitar becomes too dry, this can lead to significant damage. A room humidifier can provide much-needed moisture and water vapor for your instrument. However, it’s essential to ensure that the moisture level and humidity control are adjusted to provide the best moisture level for the best results. 

It’s essential to keep your guitar body maintained with proper humidity. This step will prevent damage caused by dry conditions, such as bad guitar strings, lifting around the bridge, sinking on the top, wood cracking, string buzzing, and other problems impacting the instrument’s physical parts and sound quality.

When you invest in a reliable guitar humidifier, you’ll prevent the effects of changing weather and environments from damaging your instrument. Humidity control is essential, especially in regions or homes with severe dryness from heating systems or frequent shifts in outdoor temperature and humidity levels.

Selecting The Best Guitar Humidifier: Buyer’s Guide

best guitar humidifier

When you choose a quality guitar humidifier, buying a device that fits your instrument and the guitar case well is essential. This small humidification system gives your guitar a balanced moisture level, only as needed. 

Different guitar humidifiers are available, depending on the style, size, and type of guitar—the three main types of humidifiers are room humidifiers, guitar case humidifiers, and soundhole humidifiers. 

The product you buy depends on how you store your guitar and whether you keep more than one instrument in a specific room or frequently travel with your instrument.

Guitar Case Humidifier

This dehumidifier fits inside the guitar case, which is ideal if your guitar shape and style don’t accommodate other types of dehumidifiers. Guitar case dehumidifiers are great for travel and don’t require much maintenance to keep them hydrated and work seamlessly. It’s also preferable if you would instead not fit this device on the guitar directly and have it control the humidity inside the case. 

Soundhole Humidifier

The soundhole humidifier sits directly on the instrument and in the guitar’s soundhole. This device resembles a rubber tube that trails from the top of the soundhole, along the guitar strings, and into the guitar body. Soundhole humidifiers are excellent for hollow-body guitars and acoustic guitars. 

Room Humidifier

If you have a collection of guitars and a specific space or guitar room, a room humidifier is excellent. Ideally, you’ll want to keep this room well maintained and free of contaminants or other items that can contribute to dryness or changes in moisture or temperature. 

The room humidifier should be set to roughly 40 to 50 percent humidity, and the temperature in the room set to around 75 degrees Fahrenheit. 

Frequently Asked Questions: Choosing The Best Guitar Humidifier

Best Guitar Humidifier

Can I use more than one humidifier for my guitar?

It’s not necessary. You’ll find that a portable soundhole humidifier or guitar case humidifier is ideal if you travel often and don’t have a dedicated room or space for storage at home. A room humidifier is best if you primarily keep your instruments in one location most of the time.

How can I take other precautions to prevent dry conditions that damage my guitar?

It’s essential to keep your guitar in good working condition and use a humidifier. You’ll want to regularly clean and maintain your instrument with a quality microfibre cloth. Always keep your guitar in a case, as much as possible, to keep its condition stable and protected. 

If you often travel with your guitar, it’s essential to never leave it in a basement or vehicle for long periods, as this can impact your instrument’s performance.

How long does a guitar humidifier last?

Guitar humidifiers last between two and six months. When you initially buy and begin using this device, you’ll find the packet moves easily between your fingers so that it can provide moisture to your instrument. Once this becomes hardened and solid, it’s no longer effective and can be discarded.

When I add water to my instrument’s humidifier, should I use a specific type of water?

Tap water is sufficient and works well. There is no need to use filtered or specially treated water.

Can a humidifier damage a guitar?

Your guitar is more likely to become damaged from excessive dryness. However, if you add too much water or mist to your guitar, it’s possible to over-humidify the material, which can cause your bridge and top of the guitar body to swell. Once this happens, your guitar cannot be repaired, making it essential to keep the moisture level balanced in the humidifier.

Isn’t my guitar case enough to protect my instrument from damage?

Guitar cases offer protection against damage, including temperature changes, sunlight, and physical damage. While there is some protection from dryness, a soundhole or guitar case humidifier provides ideal conditions for your instrument.
