HumidiPak Replacements

The D'Addario Two-Way Humidification System (formerly Humidipak), the first maintenance free, two-way humidity control system, made by Boveda, that preserves a constant 45%-50% relative humidity level within your instrument's case. This eliminates all maintenance and guesswork.

• Automatic humidity control protects your instrument against, cracks and other damage cause by lack of humidification
• No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors unlike refillable humidifiers
• Eliminates the guesswork and anxiety of maintaining your instrument’s proper humidity level
• No water, no drips, no mess
• Custom made by Boveda for D'Addario

Each Humidipro case comes with one or two packs in it, depending on the case. Each packet should last 6-8 months depending on how much the case is open.
