Boveda 62% Humidity Control Packs Size 67, 4-Pack — Protects Up to 1 lb with Two-Way Moisture Regulation

Boveda 62% RH Size 67 humidity packs are two‑way moisture regulators designed to hold up to one pound of stored product at a steady 62% relative humidity.

These compact, ready‑to‑use packs use Boveda's patented saltwater formula to balance moisture inside airtight containers. Each 5.25" x 3.5" Size 67 pack actively releases or absorbs water vapor to protect texture, aroma and weight without chemicals or complicated maintenance. The 4‑pack setup is sized for single bags or small jars and replaces approximately every three months under normal conditions.

How quickly will a Boveda 62% Size 67 pack stabilize humidity?

Once placed inside an airtight container, Boveda begins adjusting the internal atmosphere immediately and typically achieves equilibrium within 24–48 hours. Stabilization speed depends on container tightness, starting moisture and quantity stored.

• Works right away — starts regulating moisture on contact.
• Often reaches target RH in 1–2 days under normal conditions.
• Faster in small, well-sealed containers; slower in larger volumes.
• Replace packs when they feel hard or crunchy, about every three months.

How many packs do I need for my storage setup?

One Size 67 pack is formulated to protect up to one pound of product in a single sealed bag or small airtight container. For multiple bags or larger jars, use one pack per pound or per container to maintain consistent humidity.

What is inside a Boveda pack and is it safe to use?

• Sealed membrane prevents leaks — do not cut or puncture packs.
• No sprays, gels, or additives applied directly to stored items.
• Non‑toxic materials intended for storage use only — replace when firm.

How do I use Boveda 62% packs correctly?

• Remove from resealable bag; do not open or cut the pack.
• Place pack directly in the container with your product and seal tightly.
• Use one pack per container holding up to 1 lb; replace every ~3 months.
• Store unused packs in their resealable bag until needed.
