Violin Humidity Control System - Boveda 49% RH Packets
Today is extremely cold. Vermont temperatures plunge into the low single digits—snow falls as I tuck myself inside with my violin.
I came downstairs this morning, and the strings were loose over the top of the instrument—a bad sign! My poor violin is reacting to the low humidity that comes with freezing temperatures.
Failure to act could be devastating to my instruments. Dry weather can cause maple and spruce to contract.
Seams can open, pegs can become loose and sloppy, and tone can dull and lose vibrancy. Or worse! Spruce may even crack, requiring an expensive and devaluing repair!
In this video, Oren Kronick from Vermont Violins explains why proper humidification is essential for stringed instruments and demonstrates how the Boveda humidification system can protect your violin from costly damage.
A room humidifier is ideal, but a case humidifier is often more practical and reliable. We highly recommend the Boveda system.
Boveda packs have two components, so they are simple. A sleeve and an insert. The sleeve lasts forever; you simply replace the insert when it expires.
The insert is basically salt water in a special wrap that lets moisture escape into your case. It also works as a de-humidifier for times of the year when humidity rises to unsafe levels. Each Boveda pack is calibrated to target a specific humidity, 49% for instruments
After about 1-2 months of use in dry weather, the Boveda insert will become dry and crusty. Just throw it away and replace it with a fresh insert—they are only a few dollars. The beauty of the system is that, unlike
Unlike most humidifiers, Boveda requires no daily attention—just check occasionally to see if it needs replacing.
Note that a single B hop Veda will suffice for violins
And violas. Larger instruments like cellos would need two to fully function. You'll need a hard shell case.
Give your instrument the best—choose Boveda. They are inexpensive and easy to use, and Vermont violins has found them to be the most effective!

Maintain Ideal Moisture Levels with Boveda for Wood Instruments
Automatically responds to any storage environment, geographic location or change in temperature
Adds or removes moisture on its own (eliminates messy sponges, hoses, discs, etc.)
Maintains a constant relative humidity (RH) between 40-60%—the ideal climate for wood instruments
Don't store your instrument without Boveda
There's a specific geometry built into your instrument. Precision crafted in a climate-controlled shop. An artisan used intense heat, moisture and pressure to bend wood to shape your instrument. Now the care and keeping of that wood is in your hands.
Developing and fine-tuning your repertoire put significant demands on your instrument. If you expose your instrument to humidity swings day after day, you can throw off its delicate alignment and cause permanent distortion. Improper storage is the greatest constant danger to the condition of any wooden instrument.
Storing your wooden instrument in a stable environment created by Boveda preserves your instrument, and maintains its sound, so you avoid taking repairs due to:
Cracking
Warping
Sagging
Glue damage
Boveda works automatically (& solo) — so there's nothing else to add
No more adding water to sponges, hoses, or discs. No more risk of moisture puddling inside your instrument. Boveda eliminates the hassle (and danger) of one-way humidification methods. These methods spike humidity when you add water, and take a nosedive as the water evaporates.
Boveda is pure water and natural salts sealed inside a leak-proof membrane. Boveda adds and absorbs water vapor slowly and precisely to achieve and maintain an RH level between 40% – 60% in your instrument’s closed case.
How to use Boveda
Just slip the unwrapped Boveda(s) in the pouch holder. (Do not open the Boveda itself.) Nestle the pouch holder in a storage cut-out in your case where the holder will not be crushed.
