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. No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors. Note: Humidipak is designed for restoring and maintaining instrument humidity. This product is not intended for dehumidification in high humidity environments. If Your instrument has not been previously humidified or is in a known dry condition, it is recommended to use Humidipak Restore to safely reestablish the proper humidity level to your instrument and it’s case before using the Humidipak Maintain System. Using Maintain packets on a dry instrument / case will greatly shorten the lifespan of the packets. 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! ## Features - TWO-WAY HUMIDITY CONTROL – D’Addario Two-Way Humidification System is the only maintenance-free two-way humidity control system for 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 ### ⭐⭐⭐⭐⭐ 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... ## Frequently Bought Together - D'Addario Accessories Guitar Humidifier Packs-Guitar Humidifiers Acoustic - Two-Way Humidification System Conditioning Packets-24 Maintain Replacement Packets - MusicNomad (MN311) The Humitar ONE-Acoustic Guitar Humidifier & Hygrometer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/536741992-accessories-guitar-humidifier-packs-guitar-humidifiers-acoustic-two-way-humidification](https://www.desertcart.us/products/536741992-accessories-guitar-humidifier-packs-guitar-humidifiers-acoustic-two-way-humidification) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-20*
