Boveda 67g 62% Replacement Paks for CVault, 6 Pack
Six 67 g packs at 62% RH, each covering a full pound. Each one seats in the lid holder of a 2 L or 4 L CVault. The job is restocking a vault that is already in service. Pure water vapor moves across a reverse-osmosis membrane in both directions. A vault that has run dry recovers rather than only holding where it is. The fill is food-grade salt, purified water and a thickening agent, which is Boveda's chemistry. Nothing crosses the membrane except water vapor. Accuracy holds at ±2% of the labeled figure in a container sealed as well as a CVault is. This is a replacement pack of 6 rather than a container, so no vault ships with it.
A Six Pack Sized to a Replacement Cycle
Boveda runs two to four months in use and wants swapping about every three months, so six packs cover roughly eighteen months on one vault. That is the practical reason this SKU exists rather than restocking singles as they turn rigid. Running several CVaults means the six splits across them instead. Store the unused packs sealed in their bag, or they discharge into the room instead of your product. That is the one mistake worth avoiding. A pack has two clocks: two years unopened in the bag, then two to four months once it goes to work. There is no card and no dot on a Boveda, so the end is read by feel as the pack turns granular and then hard. For curing containers that is the whole maintenance routine.
Key Features
- Six 67 g Packs: Around eighteen months of replacements for a single vault on a three-month cycle.
- 62% Two-Way Control: Adds moisture to a vault that has dried out and pulls it back when the lid comes off.
- Each Protects 1 lb (450 g): Rated above the load of a 2 L or 4 L CVault, so each pack runs with margin.
- Fits the CVault Lid Holder: Seats in the built-in shelf so the pack never rests on the contents.
- Pure Water Vapor Only: A reverse-osmosis membrane means nothing but water crosses into your material.
- Food-Grade Fill: Salt, purified water and a food-grade thickener, safe resting directly against contents.
- No Activation Required: Active on arrival, so there is no soaking, charging or maintenance step.
- Tactile Replacement Signal: The pack turns rigid when spent, so no indicator card is needed.

How Long Does a Six Pack Last?
On one vault at a three-month replacement cycle, roughly eighteen months. Across several vaults it goes proportionally faster.
Which CVault Sizes Take a 67g Pack?
The 2 L and 4 L. The 8 L runs two of them, and the 21 L steps up to a single 320 g pack instead.
How Should Unused Packs Be Stored?
Sealed. Keep them in their bag or an airtight container, otherwise they spend themselves regulating the room they sit in.
When Should a Pack Be Replaced?
When it turns rigid. A fresh pack has give like a gel pillow; a spent one feels hard through the wrapper.
