Description

Simply insert the Boveda Pack into the humidifier and the rest will happen by itself! Boveda's unique bags have an osmotic membrane that automatically releases the internal moisture into the environment – at a constant 49% relative humidity. The special feature is that the membrane works in both directions, so that excess moisture can also be reabsorbed. There is no need for refilling at all. If the bag becomes hard and dry, it is simply replaced with a new one.
