Humidity can have a far-reaching effect on completely wooden or partly solid-wood guitars.

This is due to the susceptibility of wood to changes in temperature, especially moisture. We’ve reviewed the best room humidifier for guitars in this post to help you avoid damage to your guitar

The creation of guitars is done in environments with regulated temperatures. Still, when purchased from the factory, they’re stored in various settings, which may not suit them. Hence, a guitar room humidifier is necessary so you can check humidity around and inside your guitar.

You’ll, of course, be interested in preserving and protecting it so that it can serve its cause. Indeed, several guides would give you insight into maintaining the polishing of your wooden equipment. However, only a few of them will provide a comprehensive guide on regulating the humidity around the guitar. 

This is the secret behind the feeling you get when you enter a guitar store and experience a good-quality sound with their guitars. These vendors possess not just a guitar room humidifier but top ones that would preserve the quality of their instruments.

To help you easily navigate the market and select the suitable top humidifiers, we have provided a buyer’s guide for the best guitar room humidifier below. 

Best Guitar Room Humidifier: Buyer’s guide 

It is either guitar sellers, ardent collectors, or manufacturers that would know much about the features of a Grade A humidifier. However, you wouldn’t need to put that much into consideration before selecting the best guitar room humidifier.

All you need to know are the best four features and conditions humidifiers for guitars must meet. These include; the type of humidifier, size of the room, fitted with a filter or not, and the humidistat. 

Types of Guitar Room Humidifier

The kind of humidifiers you acquire would depend on a few factors. These can include the various types, and we have listed out the top three humidifiers you can pick from below:

Sound Hole Humidifier: Like its name, the soundhole humidifiers are fitted around or inside your guitar’s soundhole. They could cover the hole totally or be included among the strings and hang down into the equipment.

They are renowned for their inexpensiveness and will only function when stored in your guitar case. This is for the lone or fewer guitar owners who would only be interested in humidifying part of the room. They could as well be used in displayed guitars or stashed ones.

Guitar Case Humidifiers: This kind is designed to lie in the guitar case while protecting the whole case and wood through humidity regulation. These are ideal for guitarists who stash away their guitars properly and use them sparingly. They come with either a pouch, plastic tube, or material, making it easy for water vapor to dissipate outside the equipment. 

Room Humidifiers: These humidifiers are specially made to control the humidity of the whole room. Possessing several guitars or a music room for frequent practice is best. They’re also recommended for maintaining good health, as rooms with a humidity above 30 percent are healthy. However, they‘re surely more expensive than other types.

If you’re a singer, you may as well choose a humidifier meant for singers and steer clear from choices that employ warm mist to operate. This will avoid heat-related impairment to your instrument. 

Size of Room

You must choose a model of humidifier that could humidify the whole area. Several humidifiers specify their coverable dimension, although it is not always accurate. So, make sure you get one that would work for you. The original calculation is commonly done based on standard building plans and dimensions of different localities.

Fitted with a Filter or not

You have a choice between humidifiers with a filtering system and those that don’t have filters. However, it would be best to consider the kind that could clean your air to prevent particles from damaging your musical instrument. 

Some of these humidifiers are fitted with lifetime filters that merely need periodic cleaning, whereas others require regular replacement of the filters. Other humidifier types run different methods to purify the air. 


Having your humidifier fitted with a humidistat isn’t compulsory, as you can buy a hygrometer distinctly.  Nevertheless, it helps.  With an installed humidistat, you will have additional regulation over the productivity of your machine.

It will equally allow you to supervise the humidity levels to certify they will at no time become excessively high or low for space.
