Humidification Basics & Device Guides — Long-Term Storage

Choosing the right RH level is essential for creating a stable storage environment. Different materials respond uniquely to moisture, and RH Shield devices maintain precise humidity—50%, 60%, 65%, or 70%—using natural two‑way‑regulating beads. Lower levels like 50% and 60% RH provide dry‑leaning stability for slabs, documents, and moisture‑sensitive items, while 65% RH offers balanced preservation for most organic materials. Higher humidity at 70% RH supports moisture‑dependent goods such as cigars, tea, and herbs. Selecting the correct level ensures long‑term freshness, stability, and predictable preservation.
