D'Addario Humidipak Two-Way Humidification System

D'Addario Humidipak Two-Way Humidification System

The D'Addario Humidipak Two-Way Humidification System keeps your guitar at 45–50% relative humidity inside its case, with no water, no refilling, and no guesswork. It's built on Boveda's patented two-way technology, so it adds moisture when the air in your case is too dry and absorbs it when it's too damp.

That matters most for acoustic guitars, where humidity swings can lead to cracks, warping, and playability problems like sharp fret ends or shifting action. Refillable humidifiers only add moisture and need regular attention through the seasons. The Humidipak system works in both directions on its own, whether you're dealing with a dry winter or a humid summer.

The kit includes 3 Humidipak packets and a soft mesh pouch that won't harm your finish. Packets last 2 to 6 months and should stay in a sealed case, such as a hardshell. When they turn firm, replace them with the D'Addario Two-Way Humidification Replacement Pack (PW-HPRP-03). Recommended by Taylor Guitars, it's a simple way to protect any guitar you care about.
