Planet Waves, in collaboration with Humidipak®, brings you the first two-way humidity controller that maintains a constant 45% relative humidity level. The patented Planet Waves Humidipak completely eliminates all the guesswork and anxiety of maintaining your musical instrument's proper humidity level. No more guessing if or when to refill the humidifier and worrying about drips or mess. Unlike all refillable humidifiers, the Humidipak acts as a gauge because it provides true "two-way" purified humidity control. It adds or depletes moisture only as needed to maintain 45% RH - the ideal climate for wooden instruments such as acoustic guitars. Just place 2 packets in double pouch. Put double pouch over D and G strings and let hang down into soundhole. Place 3rd packet under guitar headstock in case. Close case, and you're done. The packet will last anywhere from 2-6 months, depending on the humidity where you are. When the packet become firm, discard and replace. The Humidipak humidity controller is as simple as that!
