Boveda has knocked it out of the park with this one! Their patented 2-way humidification system means that the humidity is regulated to the perfect level, If the level drops the Boveda packs releases moisture bringing it back up. If the humidity rises, the Boveda pack soaks it up, keeping it at the perfect humidity no matter the atmospheric changes. Unlike distilled water and PG solutions with sponges/gel/crystals/beads which can affect your tobacco products, Boveda's reverse-osmosis membrane only releases pure water vapor and Boveda will never damage anything through direct contact.

You can easily tell when it is time to dispose of the Boveda, you will begin to notice a granular feel to the pouch. Once the packet solidifies then it's time to replace.
