#1 Pick: TaoTronics Cool Mist Humidifier.

Dry air is public enemy #1 for your guitar. It doesn’t matter if it’s hot or cold—extended dry conditions will almost always lead to cracks in an all-wood guitar. Fortunately, it’s pretty easy to control the humidity around your guitar, whether it’s with a small humidifier that keeps the guitar safe inside its case, or an electronic humidifier that regulates humidity for the entire room.

Either way, the goal is to keep your guitar in an environment where the humidity level is between 45 – 55%. Simply put, too low will cause cracking and separation, and too high will cause mildew in your room.


What to look for in a good humidifier

The first question you need to answer is whether you need an in-case humidifier or an electronic humidifier for the room. If you keep your guitar inside a hard-shell case all the time, then an in-case humidifier is best. If you’re like most people who keep their guitar out on a stand or hung on the wall, then an electronic humidifier for the room is best.

If you have multiple guitars out in your room, then you’ll definitely want an electronic humidifier for the room. For the purpose of this conversation, I’m going to focus on choosing an electronic humidifier for the room.

When it comes to choosing the best room humidifier for guitars, there are a couple of things you’ll want to look for:

  • Range – the optimal range for your guitar is 45 – 55% humidity.
  • Auto Shutoff – a good humidifier should have a humidistat to monitor humidity and stop producing mist when the room reaches optimal humidity. The auto shutoff should also kick in when the device runs out of water to avoid ruining the humidifier.
  • Quiet Air Diffusion – nobody likes loud and obnoxious devices in their home. A good humidifier should be able to operate at less than 38dB.
  • Night Mode – LED displays are great unless it’s midnight and you’re trying to get some sleep. Look for a humidifier with an LED display that offers night mode and will dim or turn off the LED display while you sleep.
  • Water Tank Capacity – you don’t want to be refilling the humidifier every few hours, so look for a humidifier with a tank that holds at least 3 – 4 liters (the more the better).

Read customer reviews


The OPOLAR Digital Humidifier is the best-looking option on the list with a large touch-sensitive LED display and a very modern finish. Unlike other humidifiers that have a transparent shell that shows the water tank, the OPOLAR Digital Humidifier keeps the unsightly water tank hidden from view.

When the water level gets low, you’ll see a red notification on the LED display, and if you’re unable to refill the tank before it runs out the device has an auto-shutoff to protect it from running dry. This one has a shorter run-time and a lower mist output due to its smaller size, but it’s a perfect pick for standard-size rooms, and it won’t be an eyesore like most other humidifiers. Here are some features that make this device one of the best room humidifier for guitars.

Read customer reviews


If you’re looking for a humidifier that can regulate humidity throughout your entire house, this is the one for you. The Essick Air EP9 700 has a gargantuan 13-liter water rank with a 9-gallon output that can cover up to 2,000 square feet of living space. It’s also built to be aesthetically pleasing with black paneled sides, a hidden water tank, and a decorative natural stone tile insert on the top where you can place a vase, plant, or figurine for display.

It’s also unique in that it doesn’t emit a mist—instead, it adds moisture to the air by moving dry air through a saturated wick inside the device. That means you won’t need to worry about getting any white dust, mist, or moisture on the floor around the device, and it requires less energy than mist-producing humidifiers. Here are some features that make this device one of the best room humidifier for guitars.

Takeaways

The TaoTronics Cool Mist Humidifier offers full functionality at a great price, so that would be my go-to choice. The TaoTronics humidifier isn’t the prettiest of the bunch, though, so if you’re looking for something more aesthetically appealing I’d recommend the OPOLAR Digital Humidifier (for smaller rooms) or the HumeXL Pro (for larger rooms).
