Description
The Two-Way Humidification System is the only maintenance-free, two-way humidity control system of climate-control protection for your guitar. For smaller instruments, such as violins and violas, consider the D’Addario Small Instrument Humidifier.
This Two-Way Humidification System automatically maintains the optimal 45-50% relative humidity level within your instrument case by adding and removing moisture on demand, eliminating the guesswork and potential mess related to refilling a humidifier. Unlike refillable humidifiers, this automated system provides true “two-way” purified humidity control, eliminating the need for manual adjustments based on seasonal changes, geographic locations, temperature, or other factors.
- These packets last between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case.
- Once the packets become firm, discard and replace.
Conditioning Pads are also available for extremely dry environments.
- Once the conditioning packs bring the instrument to the 45-50% humidity range, replace them with the Humidipaks for continued maintenance.
Refill packages for Humidipaks and Conditioning Pads are available.
- Conditioning packs are sold in packs of 3.
- Replacement Humidipaks are sold in packs of 3 or 12.

Planet Waves Humidification system takes the guesswork out of worrying over having the right humidity level in my violin case. Price is great and southwest strings customer service is phenomenal.
