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.

  • The first two-way humidity control that maintains a constant 45%-50% relative humidity level within your instruments case
  • Protects your instrument against warping, cracks and other damage cause by lack of humidification
  • No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors Unlike refillable humidifiers

A guitar's best friend


Whether you are using a guitar that is laminate or a solid piece of wood...this is truly your acoustic guitar's best friend. This is a two way humidification system. It puts moisture out, and it takes moisture in when there is too much. This is the ultimate set-and-forget system out there. You put to packs in the soundhole and one under the headstock(in a case or gig bag of course) while you're not playing and it does its thing. Too many times have I forgot to fill the tube or dampen the sponge that comes with other humidifiers. The packs also last for months! This is truly the best you'll buy!



Simple, elegant solution to proper humidity


I have several solid wood guitars and live in an area of the country that gets very cold in the winter. That means ultra low humidity inside. I've tried several other in-case humidification systems and this one is by far the easiest to use. It also keeps the humidity right at the proper level for wood instruments. Newly designed pouches are much easier on my guitars. This and an in-case hygrometer and you're all set.

Warning do not use this!


These old 'humidipak' products leak and will ruin your guitar! I know from first hand, because it ruined my guitar. They have a new improved product called 'Two Way Humidification System', that suppose to have fixed this problem, but I'm not using them ever again .
