The Integra | 55% Two-Way Humidity Control Pack precisely regulates relative humidity within enclosed environments, automatically adding or absorbing moisture to maintain a consistent 55% RH. This prevents over-drying and excessive moisture, preserving the freshness, potency, aroma, and quality of moisture-sensitive products like botanicals, spices, and tobacco. Safe, non-toxic, and FDA-compliant, this easy-to-use pack requires no power or activation; simply place it with up to 450 grams (1 pound) of product or in containers up to 1 gallon.
