D'Addario Humidipak Automatic Humidity Control System

D'Addario Humidipak is the only maintenance-free, two-way humidity control system for guitar. Using Boveda's patented two-way humidity control technology, Humidipak automatically adds or depletes moisture to maintain 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.

Automatic Humidity Control System Kit: The Humidipak Control System Kit comes with three Humidipaks and two soft mesh pouches that will not harm your instrument's finish. Humidipaks last between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case. Once the Humidipaks become firm, discard and replace using the 3 refills that come in a Humidipak Replacement Pack.

Humidipak Restore Replacement 3-Pack: Humidipak Restore packs 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.

Humidipak Maintain Replacement 3-Pack: Humidipak Maintain packs automatically maintain the optimal 45-50% relative humidity level within your instrument case.

Humidipak Maintain Replacement 12-Pack: Maintain Humidipaks in a convenient bulk 12-pack.
