The D’Addario / Planet Waves Humidipak is the only maintenance free, two-way humidity control system for guitars.
It automatically maintains the optimal 40-55% relative humidity level within your instrument case, eliminating the guesswork and potential mess related to refilling a humidifier.
Unlike refillable humidifiers, the Humidipak system provides true “two-way” purified humidity control by adding and removing moisture on demand.
No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors. The 2-Way Humidity Control Kit comes with 3 Humidipaks and a soft mesh pouch that will not harm your instrument’s finish.
Humidipaks lasts between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case.
This all new, reformulated, patented 2-way humidification system maintains 40-55% relative humidity, it is recommended for maintaining the stability and playability of your instrument.
Automatic humidity control protects your instrument against warping, cracks and other damage cause by lack of humidification
No water, no drips, no mess
Once the Humidipaks become firm, discard and replace using re-fill packs.
