If you’re a music lover, you know that nothing beats the sound and feel of an acoustic guitar. But did you know that it is important to keep your instrument properly humidified? Without proper humidity, your guitar can become warped and damaged, resulting in costly repairs. So how do you ensure that your guitar stays in top shape? With the right acoustic guitar humidifier, of course! Let’s break down what makes a good acoustic guitar humidifier and which ones are the best on the market.

What is an Acoustic Guitar Humidifier?

An acoustic guitar humidifier is a device designed to maintain optimal levels of humidity within the body of an acoustic guitar. This process helps protect your instrument from warping or cracking due to dryness or excessive moisture. Generally, most people recommend keeping their acoustic guitars for blues at around 45%-50% relative humidity. Any higher than this can cause mold and mildew growth inside the body of the guitar and any lower can cause it to warp.

Types of Humidifiers

There are two main types of humidifiers on the market: active and passive. Active humidifiers are devices that require some type of power source (usually batteries) and actively pump moisture into the air around the instrument. Passive humidifiers are devices that don’t require any power source – they simply absorb moisture from their environment and release it as needed when placed in proximity to an instrument. Some examples include sponge-based products such as Dampit, Oasis OH-2, Boveda packs, Herco HE360s, etcetera.  These products generally absorb more moisture than active devices but require more frequent replacement/refilling than active devices do.  They also tend to be less expensive than active devices but not as effective at maintaining consistent humidity levels over time.  In short – they’re good for short-term use but aren’t ideal for long-term storage or use in dry climates.

How often should I use a humidifier on my acoustic guitar?

It is recommended that you use your humidifier at least once per month to maintain the desired relative humidity levels for your instrument. However, if you live in an area with dehydrated air or seasonal changes in humidity levels, it may be necessary to use it more frequently. Be sure to check the relative humidity levels in your instrument regularly to ensure optimal conditions.

Can I use regular water for my acoustic guitar humidifier?

No, it is not recommended that you use regular tap water for an acoustic guitar humidifier as it can contain minerals and other impurities which may damage the wood of your instrument. Instead, it is best to use distilled water or a special evaporative liquid such as propylene glycol solution (PGS).

What are the benefits of using a passive rather than an active device?

Passive devices require less maintenance and refilling than active devices do. They also tend to be less expensive than active devices but not as effective at maintaining consistent humidity levels over time. In short – they’re a great way to conserve energy, save money and still keep your guitar properly humidified.

Are acoustic guitar humidifiers dangerous?

No, they are not dangerous as long as you follow the recommended usage instructions provided by the manufacturer. Make sure that you use distilled water or special evaporative liquids such as PGS in order to prevent any damage to your instrument’s wood. Additionally, be sure to regularly check the relative humidity levels in your instrument and keep it within a safe range for optimal protection.
