Keep enclosed storage at a consistent 84% RH Boveda® 84% 2-way humidity control helps maintain a stable relative humidity level inside an enclosed container. The 60g pack releases or absorbs purified water vapor as needed, so it can respond to changing conditions instead of only adding moisture. 84% relative humidity: Choose this pack when your storage setup calls for a higher humidity target. Two-way control: Releases or absorbs moisture to help maintain the set RH level. 60g individual pack: A convenient size for a single enclosed storage space. Simple, low-maintenance setup: Place it inside the enclosed container and let Boveda manage humidity passively. How to use Place the Boveda pack inside a properly enclosed storage container. Keep the container closed so the pack can regulate the internal humidity. Replace the pack according to its condition and the manufacturer’s guidance. Use the RH level that matches your product and storage goals. Boveda 84% is a targeted humidity option, not a universal replacement for lower-RH packs.
