Frequently Asked Questions
Does the humidifier need to be right next to the guitar case?
You do not need the device touching the case, but it should be in the same room. A central location in the space helps distribute moisture evenly. Just ensure the mist does not blow directly onto the wood, as localized moisture can be just as harmful as dry air.
Is tap water okay to use in these machines?
Using tap water often leads to a buildup of minerals and scale inside the machine. Over time, these minerals turn into a white dust that settles on your guitar finish. Using distilled water is the safest way to keep your environment and your instruments clean.
How do I know if my room is too dry?
Use a digital hygrometer to get an accurate reading of the air moisture. If the level drops below 40%, your guitar is at risk of shrinking, which leads to sharp fret ends and a sunken top. Checking this device daily is a simple habit that saves you from expensive repairs.
Can I leave the humidifier on all the time?
Most modern units include an automatic shut-off feature that triggers when the target humidity is reached or the tank is empty. This makes it safe to leave them running while you are away. Just check the water level periodically so you do not come home to a dry room and a parched guitar.
Will the humidifier damage my guitar finish?
A high-quality humidifier is actually designed to preserve the finish by preventing the wood from expanding and contracting. The only risk occurs if you place the unit too close to the instrument, causing excessive condensation. Keep a distance of at least five feet between the machine and your guitar stand to stay safe.
