The D'Addario Humidifier Pro protects your guitar even in the driest environments. Thanks to a special water-loving sponge (hydrophilic) that holds 12 times its own dry weight of water (much more than a regular sponge), you can leave the Humidifier Pro for longer periods without having to refill. Low humidity is the worst enemy of acoustic instruments with cracks, sunken lids, warped necks, etc. as a result. For us up here in the north, it is extra important to keep the humidity at the right level, and equally important, at a constant level. The GHP Humidifier Pro does this for you, the only thing you need to think about is adding water a little every now and then.
Refilling the sponge is simple, when it is dry, you moisten it. A spill cover allows you to check the sponge while it remains in the instrument. How often you need to top up depends on how dry it is and how much airflow there is where the guitar is stored. Best for the guitar is that it is stored with the humidifier in a case.
- The sponge holds 12 times its own dry weight in water.
