The pack everything else gets compared to. Boveda is two-way humidity control: if the air in your jar is too wet it absorbs moisture, if it is too dry it releases it, and it keeps doing that until the pack goes hard. Size 8 is the small one — it covers up to an ounce, which is the right size for a pouch, a tin or a single jar.
From our own use
We use humidity packs in all of our sealed storage, both these and the Integra Boost packs. They do their job well.
- Holds a steady 62% relative humidity inside any airtight container
- Size 8 protects up to 1 oz — each packet is about 2.75" x 2.5"
- Two-way: absorbs when it is damp, releases when it is dry, and will bring over-dried material back
- Salt-and-water based, no added chemicals, safe in direct contact
- Replace roughly every 3 months — you will feel it go hard and crunchy
- Also made as Size 4 for up to ½ oz, and in 16 oz and 80 oz sizes for long-term bulk storage
If you have seen “Vivi Fresh” and wondered
Boveda's listing carries a notice that Boveda for Growers has been renamed Vivi Fresh — same product, same performance, new brand. That rename covers the grower line, the bulk packs sized for pounds rather than ounces. There is now a Vivi Fresh consumer 10-pack too, so if you searched that name and landed here, you are in the right place: this Size 8 is the equivalent, and it is the one with twenty-five years and fifty thousand reviews behind it.
Why we picked it: this is the reorder. Ten packs at this size is three to six months of actual use, and it is the part of a storage setup people forget until the jar is already dry. Pair it with a hygrometer so you can see it working, and never mix 62% with a different RH in the same container.
