Boveda Humidity Control Packs GRAV Bubblers Portable Powerhouse: Reliable and compactBoveda Humidity Control Packs Boveda's unique 2 way humidity control constantly reacts to changes in the surrounding air, adding or removing moisture to create the desired relative humidity (RH) level indicated on the pack. Boveda cannot exceed the designated RH level, which is why our usage guidelines focus on minimums rather than maximums. There's no such thing as using "too much" using more than the minimum will simply prolong its effectiveness.
