Should I use a guitar humidifier?

Yes, you can use a humidifier. However, this should be based on the humidity levels in the guitar room. You need to know the humidity levels in the room before deciding to have a humidifier. You can use a humidity monitor to measure your room humidity levels. If the relative humidity levels are in the range of 40-50%, there is no need for a humidifier. This is the best range for storing musical instruments. If it is less or higher, then you should use a guitar humidifier to ensure the instruments are safe.

Are room humidifiers bad for guitars?  

No, room humidifiers are not bad for guitars. Acoustic guitars and other forms of guitars require a certain level of humidity (40-50%) to keep in shape. This is because wood is prone to warping when the amount of moisture in the wood changes unevenly. This warping of the wood can affect the timbre of the guitar. A humidifier works by maintaining the required level of moisture in the room. This helps the guitar to keep in good shape and produce the required sound. Therefore, a room humidifier is not bad for guitars. 

Is humidity bad for guitars?  

Yes, humidity is bad for guitars. This is because guitars are made out of humidity-sensitive materials. Take an example of acoustic guitars. They are made from thin sheets of wood. These are mostly held together by glue. Both materials essentially react to humidity. This does not mean electric guitars are superior, they are also susceptible to humidity. Humidity makes guitars start shrinking, cracking and warping. The guitar can swell making the glue joints to loosen. All these effects have a direct impact on the guitars’ performance. 

What is the ideal humidity for acoustic guitars?

As highlighted above, acoustic guitars require a relative humidity level ranging between 40-50%. Anything less or higher would mean the guitar is at risk.  

What kind of humidifier is best for guitars and guitar rooms?

For guitar rooms there are three major kinds of humidifiers. These include cool mist, warm mist and evaporative. Each one of these can do a good job for you. You can choose any you prefer and you will get the expected results. Below we highlight some pros and cons of these humidifiers to help you make a choice.

  • Cool mist humidifiers. These use ultrasonic vibration to disperse water into air as vapor. They are quiet and maintain room temperature. But, they require regular cleaning and will release any pathogens if they are present in the water.
  • Warm mist humidifiers. This works just like boiling water in the kettle. When water reaches the boiling point, it releases vapor into the air. They are fairly quiet and add warmer and clean air into the room. For home guitar rooms, warm mist might be dangerous for children and pets if left unattended. Furthermore, it is difficult to regulate its mist output.
  • Evaporative humidifiers. These use fans to blow out air through filters. The water gets through the filters as the fan blows. This releases the water vapor into the air. They do not raise room temperature, and you can regulate humidity output. Conversely, it produces a lot of noise and is expensive to maintain.

Based on the above factors, we find cool-mist humidifiers best for guitar rooms. This is because they make less noise, easy to regulate humidity output and maintain room temperature. But, this does not mean others are not necessary. On the other hand, we find sound hole humidifiers best for guitars. These are fitted in the guitar’s sound hole. This is the best option for those with few guitars and do not need to humidify an entire room.

Should I get a warm or cold mist humidifier for guitars?

Both of them can add the much needed moisture to the dry air in the room.  However, cool mist would be a better choice. This is because they do not affect room temperature and it is easy to regulate their mist output. 

How to pick the best humidifier for guitar room?

  • Area coverage. It is important to pick a humidifier that can cover your room perfectly. Most humidifiers give specifications of their coverage.
  • Humidistat. a humidifier should have a humidistat to help you regulate the humidity output. Or, the humidifier should be smart enough to automatically adjust the humidity levels. This will help you ensure the humidity levels are not below or above the required level.
  • Run time. You need to consider the factor of run time. You might need to be away for long, and this should not interfere with humidity regulation in your guitar room. If you have an option for a humidifier that can operate for a longer time, you should choose it. This is because you do not need to frequently attend to it.
