D'Addario Humidipak Automatic Humidity Control System

The D'Addario Humidipak Automatic Humidity Control System is the only dual-action humidity control system for guitars that requires no maintenance.

Positioned inside the instrument's case, it automatically maintains the relative humidity level between 45-50%, eliminating all the hassles associated with replacing humidifiers.

Unlike rechargeable humidifiers, the Humidipak Automatic Humidity Control System ensures "two-way" humidity control, adding or removing moisture as needed.

Say goodbye to manual adjustments based on seasons, geographical location, temperature, or other factors. The Humidipak kit contains 3 Humidipaks and a convenient mesh fabric pouch to prevent damage to your instrument's finish.

The D'Addario Humidipak Automatic Humidity Control System lasts between 2 to 6 months and should always be stored in enclosed environments, such as a hard case. When the Humidipak dries out, it can be discarded and replaced with one of the three refills included in the package (also available separately - PW-HPRP-03).
