Following in the footsteps of the ever popular D'Addario Humidipack 2 way protection system, Boveda has created this smart monitoring humidifier. It comes as a 10-pack and will last around 3 months so makes for a steady investment. Boveda is a trusted brand that musicians count on for their guitar maintenance needs.

This humidifier is capable of providing a 40-55% relative humidity level, it requires zero activation or maintenance, thus eliminating all the hassle that can come with other guitar humidifying products. The only real stipulation being that to get the longest life possible from each pack you need to keep it stored in a sealed environment (your case) even when your instrument is out.

Over humidifying is an impossibility with this one as its natural ingredients and advanced reverse osmosis membrane ensure that the purified water vapors which it emits are kept within a precise humidity range.

As they begin to expire they start to solidify so when to change them out is unmistakable.

Guitar Humidifier Buyers Guide

As you probably have gathered from our product reviews there are a number of factors that can contribute to a less than suitable environment for keeping your guitar in. Any wooden product will wear over time, but the build of a guitar and the constant tension under strings means that the care it requires is important to keep the woods resilient and at peak strength to deal with the pressure of being strung.

There is a lot to consider before you buy guitar humidifier. Most importantly your geographic locations because where you live and the changes each season brings with it will differ regionally in the most diverse sense. The summers in various places, as well as the winters, can each bring dryer or wetter weather so you need to have a good rough idea about your humidity requirements.

It is also key to remember that your case size design and material used will also have an impact on humidity permeability.

What Is A Guitar Humidifier?

A guitar humidifier is a device that evenly disperses water vapor inside of your guitar case, and in most instances actually inside of the guitar itself. They do this is a number of different ways but essentially they consist of something very porous which either come ready to install or need to be wet. Some guitar humidifiers employ a dampened sponge or other materials with a sponge-like consistency. Many are naturally made others man-made composites. Some use clay or salts and others use more advanced composites that have been lab designed to have properties specifically fit for function. These can be in the forms of jellies, crystals, or beads. Some are engineered with materials that have super absorbency and unbelievable water retention. The capabilities are really quite smart for something that seems so simple.

The porous component is then housed in a container which also varies from product to product to keep the water from contact with the instrument itself. Then it can safely create a properly humid environment inside of your guitar case. They do work on stands also but ideally, you want a sealed area and it is always recommended guitars have somewhere to be packed away as when left on stands there is always a small possibility it could be knocked over and damaged.

How To Use A Guitar Humidifier?

Though the manners in which they function and refill can vary from one humidifier to another, in general, guitar humidifiers are pretty straightforward to use. Those we have reviewed we have given a quick description for their set up and installation and how to monitor the levels to know when they need replacing or re-moistening.

As most customers will opt for something easy to use, most competitive brands have developed humidification systems that require very little effort for your convenience.

If the product isn't one that comes damp then this will be your first step, it is recommended you use distilled water to prevent against mold and another bacterial build-up inside the humidifier (which can spread to your guitar). This may be as simple as removing (if removable) the sponge to soak it in some water or as fiddly as needing a syringe to fill it via an access point. Once filled they need placing into their enclosure which is often a plastic pod or a breathable fabric pouch. They typically hang between the strings in the center of your sound hole because it is a prime position to give the fairest dispersion of moisture, however, some sit below or above the strings in the space left so as not to stretch the strings.

They take very little maintenance, it is generally easy to keep on top of refills if you pay attention.

Do I Need A Guitar Humidifier?

Unless you live an area with a constant suitable humidity level then the outright answer is yes.

Whilst we obviously can't control the weather or dry climate what we can do is educate ourselves about the environmental factors which can reduce the quality over time and build eventually into irreparable damage and do our best to counter them.

Without maintaining a sufficient non-dry environment for your guitar will inevitably be subject to warping, swelling, bending, cracking and joint or layer separation.

Guitar Humidifier Benefits

Without a shadow of a doubt they will keep your guitar in tip-top condition and help to extend its lifespan they tackle dry weather ruin head-on and prevent against cracking which is a major concern.

A lack of humidity is actually responsible for the majority of guitar repairs so it is a pretty safe bet to say that it is an essential step in maintaining your instrument.

Best Acoustic Guitar Humidifier?

The D'Addario Humidipak is incredibly tough to beat as far as performance is concerned. Primarily because they offer 2-way protection meaning no matter the natural humidity levels and however they may fluctuate it provides a consistent sweet spot for your instrument. In addition, they provide better coverage with the headstock being taken care of as well as the body from its inside. The Boveda humidification systems are also on par but we prefer the pouch system of the D'Addario to prevent against accidental breakage.

They make for an optimal product which was the first of its kind (though many others have gone on to 2-way protection in their own ways to compete) however they do need replacing rather than re-soaking so are in essence the pricier option. The oasis humidification systems are also a highly commendable range of reasonably priced re-usable humidifiers. If budget is of real concern to you then the Herco is our best cheap humidifier.

Best Guitar Case Humidifier?

Given the fact that a large number of hard guitar cases are constructed to uniquely fit the individual dimensions and shapes of each guitar being able to fit a humidifier can on occasion be a challenge.

The clear candidate for best guitar case in our eyes for best guitar case humidifier would be the Oasis OH-6 with its compact size and unique magnetic latch on attachment concept. It allows for more flexibility to cater to differences found from case to case.


Whilst many of the humidification systems to fulfill the same function some are more environmentally friendly than others. The main factor to consider is the value of the investment. The advantages of using a humidifier to help care for your guitar are evident but you need to think about whether you want a throwaway product or something re-usable. There are many refillable options for sale each have their own pros and cons. One of the key benefits of a refill humidifier is you shell out less money in the long run however how often they need to be refilled and how easy this is to observe are also points to factor in before you buy.

There are some great humidification systems available most of them for well under the $20 mark with budget options starting from around 4 dollars so the good news is keeping your wood in good nick won't set you back.

With the given costs being so low there really is no excuse not to give one a shot and give your guitar the environment it needs for keeping in peak condition.

As ever we trust our best humidifier reviews and jam-packed buying guide will prove useful to potential purchasers before they buy.

Expert Tip

If you want to keep a closer eye on things or aren't sure of your requirements geographically or seasonally it might be wise to invest in a hydrometer.
