Boveda 62% Humidity Control Packs, Size 67, 4-Pack for Airtight Storage

Boveda 62% Humidity Control Packs are two-way humidity packs for maintaining stored items in airtight containers, with each Size 67 pack serving up to 1 lb (454 g).

• 62% relative humidity control — absorbs excess moisture or releases moisture when the container air is too dry.
• One Size 67 pack stores up to 1 lb (454 g) of items — suited to a bag or airtight container.
• Four packs per set — keep packs available for multiple storage needs.
• Natural ingredients and a saltwater-based humidity system — regulate moisture inside the container.
• Patented two-way humidity control with 25 years of experience — designed to maintain a consistent storage environment.

For items kept for consumption, transport or collection, changes in container humidity can affect freshness. Boveda 62% is made for airtight storage, including stickier, fluffier and bouncier items and storage in low-humidity climates. Add a pack when storing new items or use one to restore items that have become overly dry.

How does Boveda 62% control humidity?

Boveda 62% responds to the humidity inside an airtight container: it absorbs moisture when the air is too moist and releases moisture when the air is too dry. This two-way action is designed to bring the contents back toward the pack’s 62% relative humidity level. Boveda says its humidity control can work within 24–48 hours.

• Pack size: 5.25 × 3.5 in (13.3 × 8.9 cm).
• The system uses saltwater in the humidity pack.
• Boveda guarantees the quality of its packs.

How do I use and replace the packs?

Remove a pack from its resealable bag, place it in an airtight container, add the items and close the container. Leave the brown humidity packet sealed; do not cut or open it. Replace the pack every three months, or sooner when it feels hard and crunchy.

• Use one pack for a container holding up to 1 lb (454 g).
• Do not combine 62% packs with packs at another relative humidity percentage.
• Place a pack in each bag of new items when starting storage.

Who is the Size 67 four-pack for?

This set suits consumers, retailers and providers storing items in airtight containers for personal use, transport or collection. The pack is intended for items that benefit from humidity control, including those kept in a low-humidity climate. Boveda’s two-way system is a patented humidity-control solution, backed by 25 years of experience.

• Four Size 67 humidity packs are included.
• Use the packs in an airtight bag or container.
• The 62% version is designed for storage at that relative humidity; do not mix it with other percentages.

Boveda 62% Size 67 is a practical fit for people who want to maintain humidity while storing items for consumption, transport or collection in airtight containers. Its 5.25 × 3.5 in (13.3 × 8.9 cm) pack is sized for up to 1 lb (454 g) of stored items.
