D'Addario Planet Waves Two-Way Humidification System

D'Addario Planet Waves Two-Way Humidification System

The Two-Way Humidification System 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.

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 D'Addario Planet Waves Two-Way Humidification System comes with 3 Maintain Humidipaks and a soft mesh pouch that will not harm your instrument's finish. 

Maintain or Restore? Choose what your instrument needs
Humidipak Maintain is designed for maintaining instrument humidity. It's not intended for dehumidification in high humidity environments.

If your instrument has not been previously humidified or is in a known dry condition, use Humidipak Restore packets to safely reestablish the proper humidity level to your instrument and its case before using the Humidipak Maintain packets. Using Maintain packets on a dry instrument/case will greatly shorten the lifespan of the packets.
