Boveda 65% RH Humidity Control Packs, 4 Count Size 60 for Long-Term Storage

Boveda 65% Two-Way Humidity Control packs regulate humidity for long-term storage and aging, with a 65% RH target and four Size 60 packs in each set.

• 65% RH humidity control — supports long-term storage and aging.
• One Size 60 pack can serve up to 25 items in a plastic or wooden storage box — suited to year-round high-humidity conditions.
• Two-way moisture control — absorbs moisture when air is too damp and releases it when air is too dry.
• Saltwater and natural ingredients — support humidity regulation and freshness retention.
• ±2% RH accuracy — provides a defined humidity-control range.

Changes in moisture can affect stored items over time. Boveda packs are made for collectors and long-term storage users who want humidity regulation inside an enclosed plastic or wooden storage box, including in high-humidity conditions. Their two-way action responds to the moisture level in the air, helping prevent both drying out and over-humidification.

What does Boveda 65% RH humidity control do?

Boveda 65% RH packs take in moisture when the air is too moist and release it when the air is too dry. This two-way process is designed to help maintain storage conditions and freshness, rather than only adding moisture. In a plastic or wooden storage box, the packs help preserve flavor and aroma and maintain storage conditions within 24–48 hours.

• Designed for long-term storage and aging periods.
• Made for use during year-round high humidity.
• Helps prevent over-humidification as well as drying out.

How many items can one Size 60 pack serve?

One Boveda Size 60 pack can serve up to 25 items in a plastic or wooden storage box. The set contains four packs, each intended for use in an enclosed storage container; the stated capacity applies to one pack, not to a combined total for the set.

• Use the pack in a plastic or wooden storage box.
• Close the container lid after placing the pack inside.

How do you use and maintain the Boveda packs?

Remove the clear plastic overwrap, place the unopened brown packet in an enclosed storage container, and close the lid. Do not cut the brown humidity packet; it regulates moisture inside the container. Replace the pack every three months, and do not combine Boveda 65% RH packs with humidifier packs set to a different RH level.

• The set includes four Size 60 humidity packs.
• Keep the brown packet intact during use.
• Use Boveda packs with the same RH level in a storage setup.
