WHY THIS BOVEDA: 72% RH is for premiums in humidifier boxes made from porous materials, like wood or leather. This slightly higher RH is good if you live in low humidity or high altitudes. Use one 5.25″x3.5″ humidifier packet for every 25 TOTAL items your humidifier box can hold.

HOW BOVEDA WORKS: Boveda 72% RH keeps items fresh by stabilizing the humidity inside a humidifier box. If the air inside your container is too moist, Boveda absorbs that moisture. If it’s too dry, Boveda releases moisture into your container to bring what’s inside back to life.

CHOOSE BOVEDA: Boveda’s the only patented 2-way humidity control solution with 25 years of experience. Using saltwater in our humidity packs, we provide the fastest, most precise humidity control in the market.
