Planet Waves PW-HPK-01 Guitar Humidipak Automatic System
The D’Addario PW-HPK-01 Humidipak is the ultimate solution for two way humidity control. When your instrument is dry, moisture is released, and when humidity levels are too high, it pulls moisture back out of the case to maintain the perfect 45 - 50% humidity level. You no longer need to worry about filling up your humidifier and hoping its not releasing too much moisture.
The PW-HPK-01 Humidipak will last between 2 and 6 months. Once it becomes firm, discard them and replace them with the PW-HPRP-03 replacement packs.
