Boveda Two-Way Humidity Packs – Perfect Storage, Without Thinking About It

Anything you dry and store at home has a sweet spot for humidity. Too dry, and it turns brittle and loses its aroma. Too damp, and mould sets in. Boveda packs hold that sweet spot for you. Each one uses Boveda's patented two-way technology: it releases moisture when the air is too dry and absorbs it when the air is too damp, constantly adjusting to keep a sealed container at its set humidity.

Which Pack?

Pack	Holds	Best for
49% – 60g	49% RH	Dried mushrooms and anything that must stay below 50%, in large jars and tubs
62% – 8g	62% RH	Dried herbs, flowers, spices and chillies in small jars
62% – 67g	62% RH	The same, in large jars, tubs and storage bags

Why 49% for Dried Mushrooms?

Dried mushrooms need to stay properly dry. Above about 50% humidity they start to soften, lose their snap and become prone to mould. The 49% pack keeps them below that line, so dried shiitake, porcini, morels and other mushrooms stay crisp and keep for longer. The large 60g pack suits bigger storage jars and tubs.

Why Boveda?

Two-way control: adds and removes moisture
Set and forget: no dials, no refilling, no mess
Preserves aroma and texture of dried produce
Helps prevent mould by stopping humidity creeping too high

How to Use

Drop the pack into an airtight jar or container with your dried produce, and close the lid. Replace the pack when it feels stiff and hard all the way through, which means it has done its job.

⚠️ Please note: never mix packs of different humidity levels in the same container. They'll work against each other.

🌿 Rose's Pro-Tip: glass jars with a good seal give the best results. Boveda can only control the air it's sealed in with, so a leaky lid means it wears out faster.
