Why does it seem like my 49% RH Boveda doesn’t work?

The 49% RH Boveda are designed specifically for humidity control of wooden instruments and cases made from wood. This makes them a little different than our typical formulas which are accurate to +/- 1% RH (or lower).

For wooden instruments, we recommend that you keep them between 40-60% relative humidity to maximize the lifespan of the Boveda; the 49% packs start at the top of the range – high 50’s – and once they release their moisture, they end at the bottom of the range – low 40’s.
