Guitars have wooden parts, so you probably know that exposure to too much humidity can lead to damage.

But did you know that extended exposure to low humidity below the recommended 45-55 percent relative humidity (RH) can be just as detrimental?

What to Look for in a Guitar Room Humidifier

When shopping for a guitar room humidifier, your work is easier if you know some specific things to look for.

Size of the guitar room

For starters, you will want to pay attention to how big your guitar room really is. This is an essential consideration since humidifier manufacturers create these products for specific room sizes.

So, what is your room’s sq ft? Getting this answer can save you a lot of confusion, especially if trying to make a selection from a list like ours where every product seems to be the best choice.  

Filter or no filter?

As you may have noticed, some humidifiers such as the Venta LW25 Original Airwasher above have no filter. This feature, for instance, means the unit is easier to clean.

In addition, you will not have to worry about it losing its edge after a filter change, as in the case of the Honeywell Cool Moisture Console Humidifier.

These are just but select properties to keep in mind when deciding whether to buy a humidifier with or without a filtering system.

If you choose to go for an appliance with a filter, we recommend choosing one fitted with a lifetime filter. Such filters do not require changing; you only need to clean them from time to time.

If you decide to go for a humidifier that requires regular filter change, you may want to consider the cost of such replacements over the unit’s lifetime.

Humidifier type

Notice that we have looked at guitar room humidifiers here, which are only one category.

Other types include sound-hole humidifiers, which are tiny and hang down into your guitar, and guitar case humidifiers that sit inside your instrument’s case – as the names suggest.

Since your guitar will most likely spend more time outside its case, room humidifiers are the best investment.

They control the humidity of the entire room, so you will not have to worry about your instrument drying out while using it.

So, What is the Best Room Humidifier for Guitars? 

Our choice for the best room humidifier for guitars is the Venta LW25 Original Airwasher. Its combination of an air purifier and humidifier in one unit sets it above any standard humidifier.

This humidifier helps keep your instruments moist and dust-free while also contributing to your health by keeping the air dust- and allergen-free. 

Closely behind it is our runners-up, the AIRCARE Evaporative Whole-House Console Humidifier. This one is designed and optimized for large spaces and could keep your entire house humidified – all by itself.
