Scientifically engineered to maintain a precise relative humidity in an enclosed space, Boveda humidity control packs will never humidify beyond the RH on the pack, so there�s no such thing as �too much�. You want to think in terms of using at least the minimum because the more you use, the more efficient Boveda works and the longer they last. You�ll know it�s time to replace when the entire Boveda pack becomes solid.
Simply place the correct number of Boveda inside your container to maintain a precise relative humidity. 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 container 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.
