58% Two-Way Humidity Control PacksBoveda 58% Two-Way Humidity Control Packs Size 4, Pack of 10

A drier setting for humid homes

The 58% level is Boveda's suggestion if you live somewhere humid or prefer contents that crumble and break down easily. Each pack contains a saltwater solution that draws moisture out of the air when the container is too damp and releases it again when it is too dry, keeping the level steady. The packs are made in the USA.

Small packets for small containers

Size 4 measures about 2 x 2 inches, small enough to sit in a jar, tin or bag alongside up to half an ounce of contents. The ten packs come in a resealable bag, so unused ones stay sealed until needed. The manufacturer also suggests using them to bring overly dry items back into condition.

When to replace a pack

Plan on a fresh pack roughly every three months. A pack that has become hard, dry and crunchy has done its job and should be swapped for a new one.

How to use

Remove a pack from its resealable bag or wrapper, place it in your airtight container, add your items and close the lid. Do not cut or open the brown packet. Using more packs makes them last longer, while frequent opening makes each one work harder.
