Boveda

Boveda is the market leader in two-way humidity control for herb and tobacco storage. The US brand (Minneapolis, Minnesota) developed a patented salt-solution technology that precisely maintains relative humidity inside a container — available in ranges from 58% to 75% RH depending on the pack.

For vaporizer users, 62% RH packs are the standard: they prevent herbs from becoming too dry (worse vapor, harshness) or staying too moist (mold risk). Boveda packs release moisture when the environment is too dry and absorb it when it's too humid. One pack lasts 2–6 months depending on container size. Compatible with stash jars, humidors, and containers of any type.
