## Description

Continue to protect your investment with replacement packets for the D’Addario Two-Way Humidification System. The D'Addario Humidipak System is the only maintenance free, two-way humidity system for guitars. By adding or removing moisture on demand the Humidification Control System automatically maintains the optimal 45-50% relative humidity level within a sealed environment (your instrument case) — the ideal climate for wooden instruments. The technology behind this product eliminates humidity concerns regarding seasonal changes, geographic location, temperature, or other factors without any guesswork or mess from refilling the humidifier. It is essential to humidify all wooden instruments. Lack of humidity can cause warping, cracks and other serious damage. The D’Addario Humidipak System packets last 2-6 months and then once they become firm, you simply discard and replace them with the refills that come in the Humidipak Replacement 3-Pack. No water, no drips, no mess, nothing to maintain. Replacing the packets in the Two-Way Humidification System is a necessity to maintain the stability and playability of your instrument. For over 20 years, D’Addario has been leading the industry in innovative and problem-solving products that serve musicians worldwide. D’Addario Accessories are proudly made in a state-of-the-art manufacturing facility in the USA to the most stringent quality controls in the industry. The D’Addario family’s heart, soul and love for making music is put into every accessory we create, and we never stop inspiring performance.

Review: A must have for flying with an instrument! - I’ve used these every time I’ve flown with my Martin acoustic guitar. The pouches make using the humidifiers really easy, they fit really nicely in the case. And they do their job! They keep the humidity constant and this is a must when flying. Highly recommend
Review: Best humidity controller yet imho - I use Boveda gel packs on my sax reeds. They work great! I didn't know they had applied it to guitar as well. The D'Addario packaging is a great idea too. I love how non-intrusive it is, resting on the strings without putting more stress on them. Excellent product!

## 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

### ⭐⭐⭐⭐⭐ Best humidity controller yet imho
*by J***T on November 30, 2025*

I use Boveda gel packs on my sax reeds. They work great! I didn't know they had applied it to guitar as well. The D'Addario packaging is a great idea too. I love how non-intrusive it is, resting on the strings without putting more stress on them. Excellent product!

### ⭐⭐⭐⭐⭐ They don't tell you these are rechargeable (or for ukes), but they are
*by D***N on March 6, 2013*

This is a GREAT product (that could just benefit from somewhat better directions)! I use them with both guitars (essentially as intended) and my solid wood tenor ukulele. For the uke, with its smaller soundhole, I slip one of the cloth bags that holds a single Humidipak (designed to lay in a case under an instument's neck) between the 4 strings and the soundhole. I don't actually try to cram the guitar-hole-sized Humidipak into the uke's little soundhole, as that's neither necessary nor prudent, given that Humidipaks harden as their moisture becomes depleted --which might make it difficult to get a dried out Humidipak out. I love that these things are fairly foolproof, as I didn't like the idea of potentially damaging my solid wood Martin guitar by water dripped from a competing product. The main criticisms I've seen of these are (1) price and (2) length of use before disposal. But the online pricing is quite good, especially factoring in the fact that these are RECHARGEABLE not just disposeable. They balance humidity, right? So when they dry out, simply temporarily store them in a humid environment and... voila, good as new! My first attempt at this worked wonderfully: (1) partly fill the bottom of a relatively large, air-tight food storage container with tap water; (2) place a relatively heavy but smaller container such as a stoneware bowl that won't float in the water; (3) place some (I did 3 at a time) dried out Humidipaks in the stoneware bowl (rather than throwing them away and buying new ones); (4) close the air-tight lid on the large food storage container; and (5) wait until the Humidipaks become soft and fluid (like new) again! So perhaps buy some replacement Humidipaks so that you can be recharging some old dry ones while other moist ones are slowly discharging in your instrument case(s). That's what I'm doing, and thus far I'm 100% satisfied with the ONE-TIME up-front purchase costs (assuming I can recharge these indefinitely?). Furthermore, for the rare few who live in overly humid environments, you could use these as DE-humidifiers. Just don't make the mistake some have made in thinking that you can benefit from placing a fully moist new Humidipak in your instrument case to absorb excess moisture. First somehow DRY OUT some Humidipaks and then place the hard, dry Humidipaks (that many would throw away as trash) in your instrument case to absorb the excess moisture. Repeat as necessary...
