Why does High-Absorbency Boveda 49% RH feel thicker than Boveda 49% RH?
Different recipes. Both formulas are a combination of all-natural salts, purified water and a food-safe thickener. Boveda High-Absorbency feels more dense because its formula calls for more salt and less water than Boveda 49% RH. This special solution absorbs 3x more moisture than Boveda 49% RH. As a result, Boveda High-Absorbency will fully expand—not harden—when it needs to be replaced. (Think expanded puffer fish!)
High-Absorbency Boveda 49% RH is an innovative humidity control solution that protects wood instruments for musicians who live and play in locales with extreme humidity. (That’s 50% humidity or more for most of the year.)
Musicians can prevent warping and mildew build-up as well as humidity fluctuations by using Boveda in instrument cases. Exposing wood instruments to humidity swings day after day—going in and out of air-conditioned venues or traveling by air—can cause permanent damage. Storing with Boveda keeps wood instrument in the safe zone between 45% and 55%, which is ideal.
Remember, 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 High-Absorbency Boveda 49% RH 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.
