D’Addario Humidipak Absorb Replacement Packs

Description D’Addario Humidipak Absorb Replacement Packs are designed to safely draw excess moisture out of your instrument case and return it to a stable, protective humidity range. Built on Boveda’s patented two-way humidity control technology, these replacement packets automatically absorb excess moisture at a controlled rate, helping re-establish the ideal 45–50% relative humidity level without the risk of over-correction. High humidity can cause swelling, finish stress, altered action, and subtle tonal changes. Humidipak Absorb Replacement Packs eliminate the uncertainty of recovery. There are no dripping sponges, no refilling, and no manual adjustments. Simply insert the packets into the Humidipak pouches, place them inside your closed case, and allow the system to regulate the environment automatically. Each set typically lasts between 2–6 months depending on environmental conditions and should always be used inside a sealed instrument case for optimal performance. Once your guitar and case have stabilized within the target range, transition to Humidipak Maintenance packs to preserve consistent humidity long-term.
