The D 'Addario humidifier 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 humidity 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 humidity kit comes with 3 humidifier and a soft mesh pouch that will not harm your instrument's finish. Humidipaks last between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case. Once the humidifier become firm, discard and replace using the 3 refills that come in the humidity replacement pack (pw-hprp-03). D 'Addario is known for innovative, problem-solving, quality musical accessories, offering a complete line of award-winning accessories including cables, picks, tuners, capos, straps, humidifiers, maintenance tools and more.
