Boveda 72% RH Humidity Control Pack, Size 320 Single for Wood Humidors

Boveda is a 72% RH Size 320 humidity-control pack made to stabilize moisture in premium humidifier boxes and wood cabinets, including Spanish cedar.

• One Size 320 pack equals five Size 60 packs — use one larger pack for the same stated pack count.
• Use one Size 320 for every 100 items the humidifier box can hold — match the pack quantity to the box’s total capacity.
• Two-way control uses saltwater — it absorbs moisture when the air is too damp and releases moisture when it is too dry.
• Natural ingredients and a Boveda quality guarantee — humidity control without refilling beads, sponges or gel.
• Replace every three months, or when the packet feels hard and crunchy — a clear cue for when to change it.

Wood humidifier boxes can become too dry or too moist as their contents are stored, transported or collected. This pack is made to help maintain a stable humidity level in those containers, including when premium items are aging in wood. Add it when setting up a box with new items or use it to help restore items that have become overly dry.

How does Boveda control humidity inside a box?

Boveda absorbs excess moisture when the container’s air is too moist and releases moisture when the air is too dry. This two-way action is designed to stabilize humidity around the items in the closed container, rather than relying on a sponge that needs rewetting or beads and gel that need refilling. The saltwater humidity system is patented; Boveda has 25 years of experience with this approach and is trusted by over 3 million people. Boveda claims the system offers the fastest, most precise humidity control on the market and can maintain freshness within 24–48 hours.

• Designed for humidity control in containers of any size.
• Helps return overly dry items to their original flavorful, aromatic state.
• Boveda guarantees the quality of its humidity-control packs.

How many items can one Size 320 pack serve?

Use one Size 320 pack for each 100 items of total capacity in the humidifier box. The pack is a single Size 320 unit, equivalent to five Size 60 packs, so the capacity guidance is based on the number of items the box can hold—not just how many are currently inside. This size is suited to larger-capacity storage while the same 72% RH target is intended for premium items kept in Spanish cedar humidifier boxes and wood cabinets.

• Choose the number of packs according to the box’s total item capacity.
• Keep the 72% RH pack separate from packs with any other RH percentage; do not mix humidity levels.

How do you use and replace the humidity pack?

Remove the clear plastic overwrap, leave the brown inner packet sealed, place the pack in the humidifier box, add the items and close the lid. The inner packet is not meant to be opened. Once in place, it works without sponge rewetting, bead refills or added gel. Replace it every three months, or sooner when it becomes hard and crunchy; that texture signals that it is time for a fresh pack.

• Remove only the clear outer overwrap before use.
• Keep the brown humidity packet intact.
• Never combine different RH percentages in the same setup.

Who is the 72% RH pack made for?

It is made for people storing premium items for consumption, transport or collection, from first-time users and enthusiasts to large manufacturers and boutique brands. Its intended setting is a wood humidifier box, where items can stay in storage as they age. The 72% RH level is specifically intended for premiums in Spanish cedar humidifier boxes and wood cabinets, rather than being a universal setting for every type of stored item.

Collectors, enthusiasts and businesses using wood humidifier boxes will benefit from a pack that adjusts moisture in both directions without routine refilling. Boveda Size 320 combines a 72% RH target with a stated capacity guideline of one pack per 100 items the box can hold.
