Boveda packs are considered essential for regulating the humidity of your cigars. The moisture-regulating packets are made from natural salts and purified water. They come sealed in a patented permeable membrane. Using them can even help age cigars too.
If you’re not sure what Boveda packs actually are or how they work, you’ve come to the right place. Below, we take a closer look at how to use Boveda packs to experience the full benefits.
What Are Boveda Packs?
In short, Boveda packs are humidity-control sachets. They use a saturated salt solution to maintain a specific relative humidity level inside a sealed container. Their goal is to keep moisture-sensitive items fresh by releasing or absorbing moisture as needed. This includes cigars, cannabis, and musical instruments, and they can be especially handy when traveling with cigars.
‘Boveda’ is actually the leading manufacturer of humidity packs. Boveda packs were first developed by General Mills chemist Dr. Al Saari and Robert Esse in the 1990s. Saari sought an effective way to store his cigar collection. He wanted something that provided better regulation than a humidor.
The word Boveda actually originates from the Spanish for vault. This makes a lot of sense once you understand how they’re built. The packs have a patented two-way humidity control. They contain a natural salt solution inside a vapor-friendly membrane. This membrane makes it possible for moisture to travel inside and outside the packs.
When humidity drops in the packs’ vicinity, they will automatically release moisture. Alternatively, if the air is too humid, the packs will absorb the moisture in the air. This will help regulate a standard RH level in the packs’ surrounding environment. It protects your products, preventing them from becoming too wet or drying out.
How Do Boveda Packs Work?
It's worth understanding what's happening inside the pack, because it explains why Boveda behaves differently from an old-style sponge or gel humidifier.
A traditional humidifier only adds moisture. It has no way to take moisture back out, so if your humidor runs too damp, it makes the problem worse. Boveda works in both directions, which is why it's called two-way humidity control.
Each pack holds a saturated salt-and-water solution sealed inside a permeable membrane, calibrated to a specific relative humidity. The membrane lets water vapor pass through in whichever direction restores balance. If the air around the pack falls below its rated RH, the pack releases vapor until the air matches. If the air rises above that RH, the pack absorbs the excess. It keeps working automatically until the solution is spent, at which point the pack turns hard and needs replacing.
The practical upshot: as long as you've chosen the right RH and your humidor seals reasonably well, Boveda holds a steady, self-correcting humidity without you adjusting anything. That stability is what protects the cigars.
How to Use Boveda Packs for Cigars?
Cigars are made from tightly packed, bundled leaves. The leaves themselves are highly susceptible to changes in the environment.
If they’re subject to too much humidity, they can burn upon lighting, or become moldy. If they’re stored in too dry an environment, they can crack or even lose some of their flavor.
This is where Boveda packs come in handy. Below is our full guide on using Boveda packs properly to preserve the integrity of your cigars:
1. Choose the Right RH
Before you start using Boveda products, it’s important to make sure you choose the correct RH. RH refers to ‘relative humidity.’ For cigars, there are five primary RH levels to choose from and a cigar hygrometer makes it much easier to monitor if your humidor is actually holding that level:
These include:
- 65% RH: Use this when you prefer slightly firmer cigars, or you are storing and aging your cigars for several years.
- 69% RH: By far the most popular RH. It’s ideal for keeping cigars fresh in both acrylic and classic wooden humidors.
- 72% RH: You can use this if you have a wooden humidor that causes moisture loss. You can also use this for slightly softer cigars.
- 75% RH: Use this for humidors with poor sealage or softer cigars.
- 84% RH: This should be used only when seasoning a new humidor. Don’t use it for humidifying cigars.
2. Don’t Mix Packs
Once you’ve selected the Boveda Pack with the right RH for your humidor, take care not to use too many. You don’t want to overload your humidor, as this can result in an imbalance. Boveda recommends one 60-gram pack for every 25 cigars stored, two 60-gram packs for a 50-count humidor, and so on.
In addition, you don’t want to mix packs with different RH levels. For example, mixing a 75% RH with a 65%. Instead of increasing efficiency, the packs can actually work against each other.
As we mentioned above, storing cigars in too humid an environment can cause mold or burning.
3. Place Them Correctly
Next up, you want to make sure to place the packs properly in the humidor. Arrange them evenly inside the humidor, then close the lid properly. You need to make sure they’re tightly sealed inside.
4. Season Your Humidor
Allow them to season properly in your humidor for 14 days. This will create the proper environment for your cigars. Keep the humidor closed during this time so the moisture stays inside and conditions the wood evenly. After you’re done, remove the packs and place the cigars inside. Replace the old packs with fresh ones with the correct RH levels for your cigars.
How to Replace and Maintain Boveda Packs?
It’s inevitable that your Boveda packs will dry out over time. They’ll need to be replaced with fresh ones to maintain the proper environment for your cigars. If you’re unsure how long Boveda packs last, their lifespan usually depends on your humidor’s seal, the number of cigars stored, and the surrounding conditions.
As a rough guide, a pack tends to last around 2 to 4 months in a wooden humidor and longer, often 6 to 9 months, in a well-sealed acrylic or travel humidor, where less moisture escapes for the pack to replace.
To check if they need replacing, feel the texture of the packs. If they’re dry or brittle, you’ll need to use some fresh ones.
To prolong the life of your packs:
- Always seal your cigar humidor properly.
- Season it before use.
- Make sure to use the correct number of packs.
Tip: We advise against recharging your Boveda packs. Doing so might result in a tear to the pack’s membrane. This could spill out and damage your collection. There’s also no guarantee you’ll be able to maintain the correct RH level upon recharging.
Common Boveda Pack Mistakes to Avoid
Boveda packs are close to foolproof, but a handful of avoidable mistakes account for most of the problems people run into. Since Boveda's own guidance is brief, here's the fuller picture from a storage point of view.
- Opening the brown packet. The clear plastic overwrap comes off. The brown packet stays sealed. Tearing it open is the single most common first-timer mistake, and it ruins the pack instantly.
- Recharging a spent pack. Once a pack has hardened, the temptation is to soak it back to life. Don't. You can't restore its precise calibration, you risk splitting the membrane, and you can introduce contaminants. A fresh pack costs little; a ruined collection doesn't.
- Mixing RH levels. Running a 65% pack alongside a 72% pack doesn't average out to something in between. The two fight each other, one releasing moisture while the other absorbs it, and you burn through both faster for a less stable result. Pick one RH and use it throughout.
- Using too few packs. Underdosing is as common as overdosing. One 60-gram pack per 25 cigars is the baseline. A humidor that's under-supplied can't hold its target, especially in dry conditions, and you'll see the RH sag.
- Expecting Boveda to fix a leaky humidor. Two-way control is powerful, but it can't outrun a bad seal. If your humidor leaks air, the packs will exhaust themselves trying to compensate and drain in weeks. Sort the seal first, then let Boveda do its job.
Using Boveda Packs with Cuban Cigars
Two-way humidity control suits Cuban cigars particularly well. Handmade Habanos vary more in construction than machine-made cigars, and that makes a steady, self-correcting environment more valuable, since there's less margin for the humidity swings a one-way humidifier allows.
The one point worth knowing is that RH preference for Cuban cigars is a matter of some debate. The 69% to 70% range is the popular default and a safe place to start. Many experienced Habano smokers, though, prefer to store slightly drier, often somewhere around 65% to 67%, arguing that a touch less moisture gives a firmer draw and lets the flavors show more clearly. Others find that too dry and stay at 69%.
There's no single correct answer, and the best RH depends on your cigars, your climate, and your own taste. The advantage of Boveda here is that trying a different level is simply a matter of swapping to a different pack, so you can experiment and settle on what works for you.

Frequently Asked Questions
How do Boveda packs work?
Each pack holds a salt-and-water solution sealed in a permeable membrane set to a specific relative humidity. The membrane lets water vapor move in either direction: the pack releases moisture when the air is too dry and absorbs it when the air is too damp, holding a steady RH automatically until the solution is spent.
How long do Boveda packs last?
Usually 2 to 4 months in a wooden humidor and 6 to 9 months in a well-sealed acrylic or travel humidor. The exact lifespan depends on how well your humidor seals, how many cigars you store, and the conditions around it. When a pack turns hard or brittle, it's done.
How many Boveda packs do I need?
The baseline is one 60-gram pack per 25 cigars. A 50-count humidor needs two, and so on. Using too few is a common reason a humidor can't hold its target RH, so if in doubt, err toward the recommended count rather than under-supplying.
Can you reuse or recharge Boveda packs?
It's not recommended. Rehydrating a spent pack can't restore its exact calibration, risks tearing the membrane, and may introduce contaminants into your humidor. Given how inexpensive a fresh pack is, replacing is the safer choice.
Do you open the Boveda pack before using it?
Only the outer clear plastic, if your pack came with an overwrap. Never open the brown packet itself, that membrane is what regulates the humidity, and tearing it ruins the pack.
What RH Boveda pack is best for cigars?
69% is the most popular all-round choice. Some prefer 65% for firmer, longer-aged cigars, and 72% or 75% for humidors that lose moisture or for softer cigars. The 84% pack is only for seasoning a new humidor, not for storing cigars.
