D'Addario Humidipak Replacement Packet 3-Pack

This 3-pack of replacement packets for Planet Waves' Humidipak humidification system is an affordable way to keep your acoustic instrument at its proper relative humidity. The packets last from 2–6 months, so ordering a three pack can last you anywhere from half a year to a year and a half.

The patented, two-way Humidipak humidification system (sold separately) is a two-way humidity controller that's recommended by Taylor guitars and other leading manufacturers for maintaining the stability and playability of your instrument. This humidification system maintains 45–50% relative humidity, eliminating all maintenance and guesswork. No more guessing if or when to refill the humidifier and worrying about drips or creating a mess. Unlike other refillable humidifiers, the Humidipak humidity controller acts as a gauge because it provides true two-way, purified humidity control. It adds or reduces moisture as needed to maintain proper relative humidity, which is the ideal climate for wooden instruments such as acoustic guitars.

Just place two packets in the double pouch, place the double pouch over your D and G strings, and let it hang down into the soundhole. Place the third Humidipak replacement packet under your guitar's headstock while in its case. Close the case and you're done. The packet will last anywhere from 2-6 months, depending on the humidity where you instrument is located. When the Humidipak packet becomes firm, discard it and replace it with another Humidipak replacement packet.
