D’Addario Humidipak Absorb

Description D’Addario Humidipak Absorb safely restores your instrument and case to a stable, ideal humidity range by automatically drawing out excess moisture. Powered by Boveda’s patented two-way humidity control technology, it works at a controlled rate to bring the environment inside your case back to 45–50% relative humidity—the sweet spot for protecting tonewoods, structural integrity, and long-term playability. Excess humidity can cause tops and backs to swell, alter action, and subtly compromise tone. Humidipak Absorb removes the uncertainty from the recovery process. There are no dripping sponges, no refilling, and no manual adjustments. Simply place the packets into the included pouches, position them inside your closed case, and allow the system to regulate conditions automatically. Each set typically lasts 2–6 months, depending on your environment, and should always be used inside a sealed case for optimal performance. Once your guitar and case have stabilized within the target range, transition to Humidipak Maintenance packs to preserve consistent humidity over time.
