Boveda knows 2-way humidity control for packages and containers. We invented it.
It’s well known in science that certain salts mixed with water will naturally regulate humidity. We just patented the way that made it practical for packaging. All other packaging inserts either add moisture or remove moisture. Only Boveda does both, monitoring the RH (relative humidity) inside the container and regulating to the specific RH engineered into the Boveda.
Available in multiple sizes and humidity levels, Boveda is the only company in the world that can solve your intermediate moisture need and maintain the ideal moisture content of the items inside your container. Boveda uses all FDA-compliant ingredients and won’t damage anything through direct contact. The life of any Boveda depends how much moisture it releases, which will vary based on climate and container. You’ll know it’s time to replace Boveda when it’s no longer pliable.
