D'Addario Humidipak is the only maintenance-free, two-way humidity control system for guitar. It automatically maintains the optimal 45%-50% relative humidity level within your instrument case, eliminating the guesswork and potential mess related to refilling a humidifier. No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors. Note: Humidipak is designed for restoring and maintaining instrument humidity. This product is not intended for dehumidification in high-humidity environments. If Your instrument has not been previously humidified or is in a known dry condition, it is recommended to use Humidipak Restore to safely re-establish the proper humidity level for your instrument and its case before using the Humidipak Maintain System.
