Humidity is a personal preference for your cigars within a certain range, some people enjoy cigars a little dryer, some enjoy them with a bit more moisture. Boveda Humidity Packs come in 3 different humidity levels, 65%, 69% and 72%. It is up to you which one you prefer. Remember, Boveda Humidity Packs are bi-directional, they will actually remove moisture from a humidor that is too moist and then maintain the relative humidity that you choose.
