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.
This listing is for Restore (previously called Conditionaing) packets. The D'Addario Two-Way Humidification Restore Packets allow you to safely restore an instrument and case that is in a known dry condition or has previously not been humidified to the proper humidity level without the danger of over humidification.
