## Overview

The D'Addario PW-HPK-01 Humidipak is a maintenance-free, two-way humidity control system designed to maintain a constant 45-50% relative humidity inside your guitar case. It automatically adds or removes moisture as needed, protecting your instrument from damage caused by dry or overly humid conditions. Available in multiple sizes, it lasts 2 to 6 months per pack and eliminates the need for manual adjustments or refills, making it an essential accessory for serious guitarists.

## Description

The D'Addario Humidipak is the only maintenance free, two-way humidity control system for guitar. It automatically maintains the optimal 45-50 percent relative humidity level within your instrument case, eliminating the guesswork and potential mess related to refilling a humidifier. Unlike refillable humidifiers, the Humidipak 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 Humidipak Kit comes with 3 Humidipaks 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 Humidipaks become firm, discard and replace using the 3 refills that come in the Humidipak 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.

Review: The system seems to work fine but the bag in which the humidipaks are to ... - The system seems to work fine but the bag in which the humidipaks are to be placed is too large. I have a full sized guitar (not jumbo) and the packs still touch the bottom + the width exceeds the sound hole so it is difficult to actually hang it. Other than that these seem to work fine. For people who are in dry places the problem of these running out soon can be solved using a home-made humidifier ( can be anything, wet foam in a small box with holes or even a wet cloth placed in plastic/polythene bag). Place both in an airtight container (without touching each other) and the humidipacks will absorb extra moisture coming from your home-made one and will, effectively get refilled and will last longer. Also, for effective usage on really dry guitars, covering the sound hole with some impenetrable sheet will make the humidification process faster. The only downside is the size of the pouch given to place the humidipacks.
Review: Waste of money - Not useful for humid conditions If you are staying at high humid conditions, please don’t buy it Doesn’t work I need to switch on the Ac to get the humidity down at my place Complete waste of money

## Questions & Answers

**Q: What is the #1 cause of all instrument repairs?**
A: Lack of humidity is the leading cause of all instrument repairs. It is essential to humidify all wooden instruments

**Q: How do I recognize symptoms of a dry instrument?**
A: A dry instrument can be recognized by a number of symptoms. Sharp fret ends, neck bow, sunken top, lifted bridge, lower string height, notes starting to buzz, cracking of the neck and/or body, or change in tone of the instrument.

**Q: Which Humidipak do I need?**
A: If your instrument is not already too dry, Humidipak Maintain will maintain a constant relative humidity level inside your case. If your instrument is dry and needs to first be brought back to the proper relative humidity level, use Humidipak Restore

**Q: How often should I replace my Humidipak?**
A: Humidipaks typically last between two to six months for an instrument that is already preconditioned to 45%-50% relative humidity. They should be replaced when the packets begin to feel hard or every six months maximum, whichever comes first

**Q: What temperature should I keep the room my instrument is stored in?**
A: It's important to maintain a consistent temperature in the room where your instruments are stored. Anywhere in the range of 70-76 degrees Fahrenheit is ideal
