The large-format two-way pack. Each 67 gram Boost covers up to a pound, so this is what you reach for when you are storing a quarter, a half or a full pound and a handful of small packets will not hold the volume.
From our own use
We use humidity packs in all of our sealed storage, both these and the Boveda packs. They do their job well.
- 67 g per pack — each one handles up to 1 lb of material
- Six packs, individually overwrapped, each with a humidity indicator card inside the wrapper so you can see when to swap
- Holds a constant 62% RH: absorbs when it is damp, releases when it is dry
- Emits nothing but pure water vapour; made with materials rated for direct contact with food and consumables
- No burping required; the pack balances the container on its own
Why we picked it: this is a genuinely different job from the small packs, and the scale gap is bigger than people assume. A Size 8 Boveda covers 1 oz. One 67 g Integra covers 1 lb — sixteen times the material from a single pack. If you are storing by the ounce, small packs are fine; past that, you are either buying a handful of them or buying one of these.
The indicator card is the other reason. It is the only humidity pack in the shop that tells you when it is spent without you having to squeeze it and guess.
