Without proper humidity control, wood instruments will not perform at their maximum ability and even worse can be damaged. To maintain their shape, wooden instruments need to be stored at a stable 45-55% RH (relative humidity). Wide fluctuations in humidity will cause the wood to expand or shrink, which puts stress on the instrument and degrades its performance abilities.

Stop risking your instrument by adding water. Only Boveda’s patented 2-way humidity control adds or removes moisture as conditions require to maintain the ideal humidity level in your instrument case. Boveda helps prevent warping or cracking, and eliminates downtime for service. Because Boveda requires zero maintenance, your instrument will always be protected.

Frequently Asked Questions

When do I replace my Boveda?
As your press on your Boveda, does it feel solid? Are there only a few soft spots left? If so, you’ll want to replace it. Your Boveda has served its purpose. It’s up to you, though, if you want to thank it, or salute it as you discard it. Please note that hardening of the corners is normal and part of the usage process, and you can expect a 2-6 months usage life depending on your container and surrounding environment.
How can I maximize the life of Boveda?
Choose the largest Boveda that can fit in your instrument case. If it’s more than the recommended minimum, that’s completely fine. Your Boveda has the potential to compensate for extreme climates or seasonal humidity swings. Oh, and be sure to close the container whenever you access your instrument–the more you expose your Boveda to air, the less efficient it becomes.  
Why use Boveda to protect your instrument?
But don’t take our word for it. Listen to music experts talk about how wood type and humidity can change how your instrument sounds.
Why do I feel small crystals or hard lumps inside my Boveda?
What you’re finding is totally normal. So breathe easy—your Boveda is still doing its thing. Our signature formula is a saturated salt solution. Sometimes an excess of blended salts will mix with the water while we blend this solution then fill the inner membrane. As a result, occasionally crystals can form. These crystals will not impact the performance of Boveda’s 2-way humidity control. Your Boveda is still completely safe to use. However, if the crystals become too sharp and puncture the pouch, please reach out to us. We’ll make it right, at no cost to you.
