Boveda 58% Humidity Control Packs, Size 8, 10-Pack for Airtight Storage

Boveda 58% Humidity Control Packs are two-way humidity-control packets for keeping stored items fresh in airtight containers, with Size 8 protecting up to 1 oz.

• 58% relative humidity control — helps maintain a steady humidity level inside an airtight container.
• 10 Size 8 packets — provides humidity control for multiple storage containers.
• Each packet measures 2.75 x 2.5 in (6.99 x 6.35 cm) — fits small containers, tins, and jars.
• Natural ingredients and saltwater — power the packet’s moisture-absorbing and moisture-releasing action.
• Replace every 3 months, or when hard and crunchy — gives you a clear cue for changing a pack.

Stored items can lose freshness when the surrounding air is too dry or too damp. Boveda is made for airtight storage used for consumption, transport, or collection, including in high-humidity climates and when storing items that are easy to break down. Add a pack to a new container of items, or use one to help restore items that have become overly dry.

How does Boveda 58% control humidity?

Boveda absorbs moisture when the air inside the container is too humid and releases moisture when the air is too dry. This two-way action helps stabilize humidity around the stored items rather than only adding moisture or only absorbing it. Boveda’s saltwater-based system is designed to bring contents back to the target humidity within 24–48 hours.

• Patented two-way humidity-control system.
• Boveda has 25 years of experience with humidity control.
• The brand guarantees product quality and is trusted by over 3 million people.

How do you use and replace a Size 8 pack?

Place the unopened packet inside an airtight container, add the items, and close the container. The brown humidity packet must stay intact: do not cut or open it. Replace a pack every 3 months, or sooner if it becomes hard and crunchy.

• Remove packets from the resealable bag when ready to use.
• Use 58% packs without mixing them with packs of another relative humidity level.

What can you store with Size 8?

One Size 8 pack is intended for up to 1 oz of items in a small airtight storage container. Its compact packet format suits a jar, tin, or other small container, whether you are storing items for use, transport, or collection.

• Suitable for consumers, retailers, and providers.
• Use inside an airtight container to stabilize the humidity around its contents.

Boveda 58% Size 8 is suited to people storing up to 1 oz in airtight containers, especially in humid conditions or when items are prone to breaking down. Its two-way saltwater-based control manages moisture by absorbing excess humidity or releasing it when the air is too dry.
