Can Boveda directly touch my tobacco?

Absolutely. Boveda is 100% safe to lay on / in / amongst your tobacco.

What humidity level do I need?
Boveda is available in 62, 65, 69, 72, 75 and 84 (exclusively for seasoning). All Boveda are accurate to +/- 1% of the RH printed on the pack in an air-tight environment. Humidors are not air tight. Depending on humidor quality and ambient conditions, it’s not uncommon for the actual RH to be stable anywhere from 2-6 points below the Boveda RH you’ve chosen. This is why we recommend 72% for your first set after seasoning. If it’s 72 on the nose, you’re perfect. If it drops a few points, you’re still perfect. Based on how your humidor performs, you can decide whether to move to 62, 65, 69 or 75.

I’ve been using my humidor for a while, do I need to re-season?
A. If an accurate hygrometer (calibrate it with our calibration kit) tells you you’re 60% or less, re-season it with our 84% Boveda. While the humidor is re-seasoning, REMOVE all cigars, put them in Tupperware with 69 or 72% and they’ll be perfect while your humidor conditions. It MAY NOT take the usual 14 days to season, since you’re starting somewhere in the middle. Calibrate your hygro with our calibration kit and only leave the 84% in (1 per 25 cigars the humidor holds) until the RH inside reaches 68-72%.
B. If an accurate hygrometer (calibrate it with our calibration kit) tells you it’s 60% RH or more, just use the 1 Boveda per 25 cigars it holds in 72%. This way, the 72’s are doing the rest of the seasoning while caring for your cigars and keep you at a safe RH once it’s finished. NOTE: Because the Boveda are essentially seasoning while caring for the cigars, they’re working double hard. So the first set of Boveda will not last as long as subsequent sets will.
C. If you haven’t calibrated your hygrometer with our kit, you can never be certain what’s happening in your humidor or how to fix it. Hygrometers are imprecise and require calibration. With our one step kit, you’ll know the accuracy of your hygrometer in 24 hours.

Do I use Boveda along with sponge/crytals/gel/beads?
No, throw them out. They’re only reservoirs for holding water and only give off 100% humidity – despite their claims. Those items give off flavors and films that keep you from enjoying your cigars the way the master blender intended.

How do I choose the right number of Boveda?
We recommend using at least one 60 gram Boveda per 25 cigars your humidor holds, even if it isn’t full. It’s still air space and wood that needs proper humidification. And because Boveda will never over-humidify beyond the number on the pack, using more than is recommended will just work more efficiently and need to be replaced less often. So with Boveda, you can never buy more than you need.

When do I know when they need to be replaced?
All Boveda will turn into a solid wafer when they’re dead. So it’s short of that, when there aren’t many soft spots left, that you’ll want to replace them. Pronounced crystallization and hardening of the corners first is completely normal.

Do I need individual packs, a cube or a brick?
Individual packs are wrapped in clear plastic to give them a two year shelf life. A cube is just 12 individually wrapped Boveda. A brick is a little different, it’s 20 unwrapped Boveda. As long as you re-close the master bag after removing the next round of Boveda for your humidor, they’ll have a two year shelf life inside the bag. Buying by the brick gives you the best Boveda pricing available.

Why shouldn’t I use Boveda with other humidification devices?
Boveda was designed as a stand-alone 2-way moisture control.​ When you introduce a wet sponge, crystal, gel or beads, Boveda is absorbing the very high humidity given off by these 1-way humidification devices, giving you mixed results. Just use at least one Boveda per 25 cigar capacity for perfect and predictably precise results.

3 Things you should know about using boveda:

(1)When It’s dry & crispy, it’s time to replace.

When Boveda is completely dry, it will turn into a solid wafer. It’s just short of this, when there are very few soft spots left, that you’ll want to replace them.

(2) The More you use, the longer they last.

Adding more than the minimum amount of humidity control packs recommended by Boveda is perfectly ok and in some cases required for dry climates, seasonality, or very leaky storage containers.

(3) The more you expose it to air, the harder it has to work.

If your Boveda is being depleted quickly (less than 2 months) then you know that Boveda is working extra hard to keep that environment stable. The solution is to verify your humidor doesn’t need to be re-seasoned, or to add more Boveda packs.

How Boveda Is Made

Boveda works on the scientific principle that certain salts combined with water will naturally regulate humidity. Our patents are on what makes this portable and usable in packaging and containers. The film that encases Boveda will only allow the transfer of water vapor and won’t cause any damage to product or packaging through direct contact.

All Boveda products are maintenance free and require no activation. For medical instruments, we also know that a number of Boveda formulas are stable under gamma radiation sterilization.
