HOW BOVEDA WORKS
Each Boveda consists of a specially prepared saturated solution of pure water and natural salt. This saturated solution is contained within a water-vapor permeable "reverse osmosis" membrane. Within a closed desktop humidor Boveda maintains a predetermined level of (RH) by releasing or absorbing purified water-vapor, as needed, through the membrane.
Boveda provides the cleanest and most purified humidity of all other products available on the market today.
Note: Do not mix Boveda RH levels within the same humidor, and do not use Boveda in the same humidor with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
