Top Five Best Guitar Humidifiers

Did you know that your acoustic or classical guitar is under constant threat if you live in a dry climate? Most beginner and intermediate players don’t know this, but keeping the wooden instruments safe with the proper humidity is imperative, so finding the best guitar humidifier should totally be your worry today!

You don’t want the wood of your acoustic guitar to be living in conditions that make great firewood like is the case with dry climate; instead, you want the living conditions to be nice and with the right humidity levels (opt for digital hygrometer if you don’t have one so you can measure). If you don’t take proper care of the wood that your guitar is made from, disastrous things can happen!

Your guitar is not created to be able to withstand major changes in humidity; guitars are assembled in factories where the humidity is put under strict humidity levels control. Guitar manufacturers understand that there when there is the slightest change in humidity, they risk warping or swelling the wood of the guitar before the instrument is even finished, damaging the acoustic permanently.

Even guitar stores tend to be a bit cooler than the average home and this is just to ensure that the guitars are not exposed to any temperature and humidity extremes.

Once the guitar you purchase finally ends up in your hands, you have to keep up with the maintenance! Some guitar owners spend thousands of dollars on their guitars but don’t understand that they have to give their guitars a proper humidity place to be stored.

Having an acoustic guitar that’s dried out doesn’t sound terrible, but it can have disastrous results. A guitar that’s dried out can cause the guitar to crack, which alters that glue to dry out, the wood to separate, major changes in the actions, frets to stick out, and joints to become loose. All because you didn’t keep your guitar in a humid environment! Do find here all you need to know to ensure your acoustic guitars a good life with the proper type of humidifier.

Before Buying Tips

Before you go and start researching any old humidifier for your guitar, you need to know that there are actually two different types of guitar humidifiers. There are:

  • Guitar case humidifier
  • Soundhole humidifier

Guitar case humidifiers sit inside of the guitar case and typically rest right underneath the headstock.

Soundhole humidifiers are the more popular humidifier. These types of humidifiers can either cover the soundhole or sit right in between the strings of the guitar.

You can also purchase a guitar room humidifier in order to provide humidity for your guitar. The room humidifier will keep the entire room your guitar is stored at a steady level of humidity. If you own several guitars, this is probably the best option for you to go with.

While purchasing an acoustic guitar humidifier is important, how you use it is also important. If you don’t use your humidifier properly, you’ll also risk damaging your guitar, so first, make sure you discover how your humidifier works. Make sure that when you use a sponge for your humidifier, that it’s a damp sponge, not a soaking wet one. Having a dry guitar isn’t good, but having a wet guitar is also not what you’re looking for.

Also, make sure that your consistently check on your humidifier; no two environments are the same, so you should monitor your humidifier to see when it needs to be re-hydrated. You should need to dampen your sponge at least once a week.

Planet Waves Humidipak Two Way Humidity Control System

The planet waves humidifier is a good humidifier that maintains the humidity level as a consistent 45%. It’s easy to use, especially because you don’t want to worry about sponges or water vapor. If you purchase the Humdipak Kit, you’ll receive three Humidipaks that come along with a mesh pouch that will allow you to avoid harming the finish of your guitar.

The biggest complaint about the Planet Waves Humidipak Control System is that when it’s inserted, it stretched the strings on the guitar out. Also, if you want to truly take advantage of the entire humidifier system, you’re going to have to store your system in your hard case. There is also no measuring device for the amount of humidity the system is putting out.

Oasis Instrument Humidifier

The Oasis Instrument Humidifier is very popular mainly because the most recent models humidify the entire case, not just the instrument. This means that you don’t have to stick the humidifier into the guitar, lowering the chance of you damaging your guitar.

Not to mention that the Oasis Guitar Humidifier can raise the humidity an extra ten percent if you live in a very dry air environment! I also love how that when the humidifier gets low on water, the humidifier collapses, so there’s no second-guessing if your humidifier needs water.

The downfall to that is that this device does tend to dry out quickly, so make sure that you consistently check the device.

Kyser Life Guard Humidifier

The Kyer Life Guard Humidifier is great if you want to keep your guitar displayed on a stand; this humidifier covers the soundhole, which ensures that the humidification is distributed evenly throughout the guitar. I personally recommend this humidifier to anybody who doesn’t like keeping their guitar in a case and likes to leave it out on display.

The Kyser Lifeguard humidifier fits very well into the soundhole, so it’s not going to be a sight for sore eyes. However, if you have a sound hole that isn’t shaped like the generic sound hole is, this humidifier may be a struggle for you to get into the guitar.

Music Nomad Humitar

The humidifier from Music Nomad has a very low profile in the soundhole, which allows you to completely close the top of your guitar case without hitting the humidifier. You also don’t have to worry about dripping with this humidifier, as the synthetic sponge that’s in this humidifier holds more water than a typical humidifier and it comes with an Anti-Drip function.

Also, there’s no need to buy any replacement packs because this is a one-time purchase! The only downfall with the Humitar is that it is recommended that you only use distilled water for the humidifier.

Martin Guitar Humidifier

The Martin Guitar Humidifier is shaped like a snake and is made from fine materials, which allows this humidifier to absorb ten times its weight in water. There are holes in this humidifier which allows moisture levels to slowly come out of the holes; this is a very simple design. You can just stick the tube around the sound hole and it’s super affordable!

The only con about the Martin Guitar Humidifier is that it doesn’t have any sort of device to measure the amount of humidity that the device produces.

FAQs About Guitar Humidifiers

How important is it to humidify the guitar?

Very. If you want to prolong the life of your wooden instrument no matter if it is a guitar, banjo, violin, you have to use a humidifier and a hygrometer inside your case, so you can keep the instrument in a perfect temperature that will not alter the wood and will not allow altering the volume and tone.

Can you over humidify a guitar?

Yes. The ideal humidity should be 40-45% because higher levels can alter the wood, increase the chances of mold growing in your guitar, and also, complete alteration of the tone, which is something that no player wants to experience.

Can a guitar humidifier make your guitar sound better?

No. Guitar humidifiers cannot make your guitar sound better, however, they protect your guitar from wetness, alteration and permanent damage, so you definitely should use one for your instrument. Having installed one and re-wetting it every 5 to 7 days will allow your instrument to remain in perfect shape and sounding as the first day you bought it.


You should not be hanging your guitar on the wall every day, all day. Keeping your guitar stored in a hard case is the best way to protect it from physical damage and the different changes in the elements.

Hard cases are better for your guitar compared to soft cases, but soft cases still offer some protection from the temperature and minimal physical damage. If you have a lot of guitars in one room, you may have to purchase two humidifiers, which is completely normal!
