About this product

Boveda (pronounced Boh-vuh-duh) invented the world’s first 2-way humidity control in a ready-to-use packet. Inside Boveda’s semipermeable membrane contains all-natural salts and purified water. It’s all science. Mix certain salts with water and together they naturally regulate humidity. Boveda’s patented packaging allows the cleanest, most-purified water vapor to either be emitted or absorbed. Boveda acts on the environment around it. By adding and absorbing moisture, Boveda keeps the contents of a sealed container at a precise relative humidity (RH) level. Cool, huh?
