D'Addario Humidipak Maintain Replacement Pack (Single)

The D’Addario Humidipak Maintain Replacement Packs are part of the Humidipak two-way humidity control system, designed to keep instruments stored at a stable 45–50% relative humidity inside the case. The packets automatically add or absorb moisture as needed, helping protect guitars and other wooden instruments from cracking, warping, or dryness.

These replacement packs are used with the Humidipak Maintain system and provide consistent humidity control without refilling or manual adjustments.

Features

• Two-way humidity control maintains 45–50% RH inside instrument cases

Important Note

Humidipak Maintain packs are intended for maintaining proper humidity levels, not restoring very dry instruments. If the instrument or case is already dry, use the Humidipak Restore system first before switching to Maintain packs.
