Planet Waves Two-Way Humidification System

The Planet Waves Two-Way Humidification System automatically maintains the optimal 45-50% relative humidity level within your instrument case. No more guessing or adjusting—the Two-Way System adds or removes moisture in your case as conditions dictate. The system comes with 3 Humidipaks and a soft mesh pouch that won’t harm your instrument's finish, without water, drips, or mess. Humidipaks last between 2-6 months.

We strongly recommend humidifiers, especially during the winter months, when central heating systems can easily cause indoor humidity to drop below 20%. According to Jeff the Repair Guru, you should use a humidifier, “…from the time you turn on your heat until you shut it down in the Spring.”
