Boveda 62% 2-Way Humidity Control Packs 67g

Boveda 67g 62% Humidity Control Packs Hold a Full Pound One 67 g pack covers a pound of material at 62% RH. This is the size operations reach when jars give way to curing containers. Pure water vapor crosses a reverse-osmosis membrane in both directions, so a container that has run dry recovers instead of just holding where it is. Measuring 5.2" x 3.5", it seats in the lid holder of the 2 L and 4 L CVault. The 8 L takes two of them rather than one, because eight liters of headspace needs more buffering. The fill is food-grade salt, purified water and a thickening agent, which is Boveda's chemistry rather than Integra's salt-free blend. The membrane keeps that solution on its own side, so the pack is safe resting against contents. A One Pound Humidity Pack for Curing Containers and Humidors Sizing above the load is deliberate. A 67 g pack on a three-ounce jar holds RH flat far longer between swaps. In a true airtight container it holds ±2% of the labeled figure. In a wooden humidor, which leaks by design, expect the reading to settle up to five points lower. Do not chase it with more packs. Replace when the pack loses its give and turns granular, because that is the only maintenance there is. There is no indicator card on a Boveda pack, so the check is done by hand rather than by eye. Unopened packs keep two years, and in use one runs two to four months on a roughly three-month cycle. The same pack is stocked as a 6 pack and by the case for anyone running several containers. Key Features 62% Two-Way Control: Adds moisture to a container that has dried out and pulls it back when the lid comes off. Protects 1 lb (450 g): Sized so the pack has capacity in hand rather than running at its limit. 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. 5.2" x 3.5" Footprint: Seats in a lid pak holder without taking volume that would otherwise hold product. Tactile Replacement Signal: The pack turns granular then solid when spent, so no indicator card is needed. 2 Year Shelf Life: Sealed stock keeps, so holding stock ahead does not mean losing packs to age.

UPC 850661003182 SKU BOV60G How Much Does a 67g Boveda Pack Hold? A full pound, or 450 g. Two of them handle an 8 L CVault, and the 320 g size covers five pounds. Which Containers Take a 67g Boveda? It is the replacement pack for the 2 L and 4 L CVault, and suits full-size humidors and humidor bags. Why Does My Humidor Read Lower Than 62%? Humidors are not airtight. Actual RH commonly settles up to five points under the labeled figure depending on build quality and room dryness. How Long Does a 67g Pack Last? Two to four months in use, on a three-month replacement rhythm. Sealed and unopened it holds a two-year shelf life.
