Planet Waves 2-way Humidification System (PW-HPK-01)

Planet Waves (D'Addario) PW-HPK-01 Humidification 2 way Guitar humidifying system includes 1 headstock pouch, 1 soundhole pouch, and 3 Humidipak packets. We also offer refills for this system. No worrying about maintaining the correct humidity for your guitar. No need to add water, this system does the job for you. D'Addario brings you Boveda's patented technology as part of their instrument care line. The Two-Way Humidification System (formerly Humidipak) 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, this 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 Two-Way Humidification System comes with 3 Humidipaks and a soft mesh pouch that will not harm your instrument's finish. These packets last between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case. Once the packets become firm, discard and replace using the 3 refills that come in the D'Addario Two-Way Humidification Replacement Pack (PW-HPRP-03). This all new, reformulated, patented two-way humidification system maintains 45-50% relative humidity which eliminates all maintenance and guesswork. This system is recommended by Taylor guitars and others for maintaining the stability and playability of your instrument. Videos
