Each Boveda consists of a specially prepared saturated solution of pure water and natural salts. This saturated solution is contained within a patented water-vapor permeable reverse osmosis membrane. Boveda humidity packs provide the cleanest and most purified humidity of all other products available on the market today. All Boveda products are maintenance-free and require no activation.

Boveda's patented 62% humidity control packs regulate moisture content; providing 15% higher terpene and flavor retention than when stored without Boveda and adding or removing pure water vapor, as needed, to maintain a precise relative humidity (RH). Only Boveda responds to any atmospheric humidity conditions inside a container by maintaining the predetermined relative humidity (RH) level of 62%. They don't need any activation or maintenance. Just place them in an airtight container with your items and Boveda technology will do the rest. Your material will stay fresh, with stable moisture content, delivering a consistently exquisite experience every time.
