Even in drippy locales, humidity control is no sweat for Boveda. Boveda 49% RH High-Absorbancy are specially designed for musicians who live in a climate with 50% humidity or more for most of the year. Not sure if this is you? Check your local humidity levels. (Lower humidity? Choose Boveda 49% RH for wood instruments.)

Information

Year-round extreme humidity? Formulated to protect wood instruments in year-round extreme humidity level of 50+%

Protects instrument from warping and mildew build-up while balancing the humidity level in your case.

Tested in a lab at rainforest-like conditions! Absorbs 3x more moisture than Boveda 49% RH.

Keeps wood instrument in the safe zone—Automatically achieves and maintains a constant relative humidity (RH) level between 45% and 55%. 

Prevents humidity fluctuations. Exposing your wood instrument to humidity swings day after day—going in and out of air-conditioned venues or traveling by air—can throw off its measured alignment and cause permanent damage.

How to use Boveda in your instrument case:

  1. Remove Boveda's plastic wrapper. (Do not open the Boveda itself.)
  2. Slip the unwrapped Boveda into a protective pouch of its leak-resistent fabric holder (available separately)
  3. Place in case and close the lid. Always keep your case closed when using Boveda.

No maintenance for months! Initially, Boveda has some catch-up work to do, so your first Boveda won't last as long as subsequent ones. After your first set, Boveda will last 2-6 months depending on the time of year, your climate and your case. When Boveda 49% RH High Absorption fully expands, it’s time to replace it.

Effective and versatile 2-way humidty control—safe to use in an ABS plastic or fiberglass cases, wooden cases and soft case or bag. (Boveda will last longest in rigid cases.)

Choose how many—High-Absorbancy Boveda is available in packages of 4, 12 and 20.

Packaging:

Unopened, Boveda can stay fresh for up to 2 years in its overwrap and sealed bags.

Unwrapped in resealable high-barrier plastic bag with zip closure: 

  • 4 pack

Individually wrapped in factory sealed in a high-barrier plastic: 

  • 12 pack

Unwrapped in recloseable high-barrier plastic bag: 

  • 20 pack

Always insert Boveda into the pouch of a Boveda fabric holder before placing in an instrument case. Within the same wooden instrument case, do not mix Boveda 49% RH High-Absorbancy and Boveda 49% RH or different Boveda RH levels. Instead of creating a new “average” RH, the moisture will merely transfer back and forth between the Boveda. Do not use Boveda with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
