HUMIDIPAK MAINTENANCE
Automatic humidity control system
PW-HPK-01
D'Addario Humidipak is the only maintenance-free, two-way humidity control system for guitars. It automatically maintains the optimal relative humidity level of 45-50% within your instrument case, eliminating the guesswork and potential mess of refilling a humidifier. No more manual adjustments based on seasonal changes, geographic locations, temperature or other factors. Note: The Humidipak is designed to restore and maintain instrument humidity. This product is not intended for dehumidification in high humidity environments. If your instrument has not been humidified previously or is in a known dry state, it is recommended that you use Humidipak Restore to safely restore the appropriate humidity level for your instrument and this is done before to use the Humidipak maintenance system. Using Keep pouches on a dry instrument/case will significantly reduce the life of the pouches.
