Keeping a few cigars at the right humidity can become frustrating when a small or travel humidor loses moisture faster than expected. Boveda 72% RH Size 8 is a compact two-way humidity control pack designed to add or absorb moisture automatically inside a closed storage environment. The 72% version makes the most sense when you use a draftier humidor, live in a dry environment, or specifically prefer a higher-moisture cigar profile. Its main limitation is just as important: 72% RH is not the best target for every cigar-storage setup.
Quick Verdict
Rating: 8.7/10, Recommended with caveats
Best For: Small and travel cigar humidors that need a 72% RH target, especially in dry conditions.
Bottom Line: Boveda Size 8 is simple, compact, and requires no water refills or electronic controls. The important tradeoff is that 72% RH is a specialized humidity level, so you should confirm that it suits your humidor and cigar preference before buying.

What Is the Boveda 72% RH Size 8?
Boveda Size 8 is a small humidity-control packet that works inside a closed cigar-storage container. Instead of requiring you to refill a sponge, add water to beads, or adjust an electronic humidifier, the packet automatically responds to the moisture level around it.
The reviewed version targets 72% relative humidity. Boveda positions this RH level as a specialty option for cigar owners dealing with dry conditions, draftier humidors, or a preference for slightly higher cigar moisture. Size 8 is intended for smaller storage setups rather than large desktop humidors.
Before You Buy: Do not choose 72% simply because the number is higher. Boveda identifies 69% RH as its more universal cigar-storage choice. The 72% version is better suited to dry environments, draftier humidors, or buyers who deliberately want a higher-moisture profile.
Who Should Buy It?
Best For
- You keep a small number of cigars in a travel or compact humidor.
- Your storage environment is dry or your humidor tends to lose moisture.
- You want two-way humidity control without adding water or maintaining a sponge or gel system.
Skip If
- You want the more commonly recommended 69% RH level for general cigar storage.
- You have a large humidor that would be better matched with larger Boveda packs.
- You plan to mix several RH levels or combine Boveda with another humidification system.
How Boveda’s 2-Way Humidity Control Works
The packet contains purified water, salts, and a thickening agent sealed inside a membrane. When the surrounding environment becomes too dry, water vapor can move out of the packet. When moisture rises above the pack’s target range, the system can absorb moisture instead.
This two-way response is the main advantage over basic one-direction humidifiers. You do not manually decide when to add moisture. You place the correct number of packs in a properly closed container and allow the packets to respond to changing conditions.
Boveda states that its packs maintain the printed RH within approximately ±2% when the recommended number of packets is used. A leaky humidor or extremely dry room can reduce how closely the storage environment holds the target humidity.
Is 72% RH Right for Your Cigars?
This is the most important buying decision. Boveda describes 69% RH as its most universal option for cigar storage. By comparison, 72% RH is intended for people who prefer a higher moisture profile or have difficulty maintaining their desired RH because the environment is dry or the humidor is somewhat drafty.
A higher number is not automatically better. If your humidor already seals well and stays stable, 72% may be more humidity than you want. Your cigar preference, local climate, container type, and existing hygrometer readings should guide the choice.
Pro Tip: Check the actual RH inside your humidor before changing humidity levels. If your current setup already stays where you want it, switching to 72% just because it is a higher percentage may create an unnecessary change.
Sizing and Placement Tips
Boveda’s Size 8 guidance is based on the capacity of the humidor, not just the number of cigars currently inside it. Use one Size 8 packet for every five cigars the container can hold.
For example, a 10-cigar travel humidor calls for two Size 8 packs. A 12-cigar-capacity case would need three because its capacity exceeds ten cigars. For larger humidors, Boveda recommends moving to larger pack sizes rather than filling the container with many Size 8 packets.
Remove a packet from the resealable outer bag, place it in the humidor or small case, and close the container. Do not cut open the brown humidity packet. Reseal the unused packs in their original outer bag so they remain protected until needed.
How It Performs in Real Use
Small Travel Humidors
Size 8 is particularly well matched to compact travel storage because its 2.75 × 2.5-inch footprint takes up little space. You can choose the number of packets according to the case’s cigar capacity instead of installing a separate humidifier.
Dry Indoor Conditions
The 72% version is most relevant when dry ambient conditions or a less-than-perfect seal make it difficult to hold your preferred humidity. The packet can release moisture as conditions fall, but a severely leaky container will still make the pack work harder and shorten its useful life.
Occasional Cigar Storage
For a small collection that stays inside a closed case most of the time, the hands-off design reduces routine maintenance. You should still inspect the packets periodically rather than assuming they will remain active indefinitely.
Multiple-Cigar Travel Cases
The sizing system is easy to scale. One Size 8 covers up to five cigars of capacity, so a larger travel case may simply require two or three packs. Correct sizing matters because using too few packs can make it harder to maintain the intended RH.
When Should You Replace a Boveda Pack?
Boveda recommends replacing active packs about every three months as a general rule. Actual life can change with container quality, room conditions, and how often the humidor is opened.
The touch test is also useful. A pack can still be working when only its corners are hard or when it has a mixture of firm and soft areas. When the entire packet becomes rigid at room temperature, it is at or near the end of its useful life and should be replaced.
If a packet feels hard because it is cold, allow it to return to room temperature before judging it. Do not try to restore a used Boveda pack by soaking it in water, since the manufacturer warns that reactivation can interfere with the pack’s calibrated humidity control.
Materials and Safe Use
Boveda lists food-grade salt, purified water, and a food-grade thickening agent as the ingredients inside the packet. The contents remain sealed behind the packet membrane during normal use, and Boveda states that the exterior packet can safely touch cigars.
Do not cut, puncture, or intentionally open the brown packet. You should also avoid mixing different Boveda RH percentages inside the same humidor. Boveda advises against combining its packs with another active humidification product because the systems may work against one another.
Pros and Cons
Pros
- Two-way system can both release and absorb moisture.
- Size 8 is compact enough for small and travel humidors.
- Simple sizing rule of one pack per five cigars of capacity.
- No water refilling, sponge maintenance, or power source is required.
- 72% option is useful for dry environments and humidors that struggle to retain moisture.
Cons
- 72% RH is not the best humidity target for every cigar owner.
- Size 8 is inefficient for larger humidors that need bigger packs.
- Packs are consumable and require periodic replacement.
Is It Worth the Price?
Boveda 72% RH Size 8 makes the most sense when convenience matters more to you than maintaining a reusable humidification device. There is no reservoir to fill, no sponge to wet, and no powered controller to configure. For a small travel humidor, that simplicity can make it a strong value.
The recurring cost is the main value tradeoff. These packs are consumable, and Boveda recommends replacement roughly every three months during active use. If you have a large humidor, moving to a larger Boveda size may make more sense than using many Size 8 packets.
How It Compares to Alternatives
Within Boveda’s own cigar range, Boveda 69% RH is the more universal choice and is better suited to buyers who do not specifically need a higher-moisture target. Boveda 65% RH is an alternative for people who prefer a drier cigar profile. The 72% version stands out when dry conditions or a draftier humidor make higher-output humidity control useful.
Integra Boost is another two-way humidity-control system available in 72% RH and 8-gram sizes. Its approach differs in formulation and it offers a separate replacement indicator system. Boveda Size 8 makes the most sense if you specifically want Boveda’s salt-based system and its straightforward one-pack-per-five-cigars sizing guidance.
Frequently Asked Questions
How many Boveda Size 8 packs should I use?
Use one Size 8 pack for every five cigars of total humidor capacity. A 10-cigar case needs two, while a 12-cigar-capacity case requires three.
Is 72% RH better than 69% RH?
Not automatically. Boveda describes 69% as its more universal cigar-storage option, while 72% is better suited to dry environments, draftier humidors, or buyers who prefer a higher moisture profile.
How long does Boveda 72% Size 8 last?
Boveda recommends replacing active packs about every three months. Container seal quality, ambient humidity, and how often you open the humidor can affect actual lifespan.
How do I know when a Boveda pack is finished?
Check it at room temperature. Some firm corners are normal, but when the entire pack becomes rigid and has lost its pliable areas, it is time to replace it.
Can I recharge a hard Boveda pack with water?
Boveda advises against soaking or otherwise trying to reactivate an exhausted pack. Doing so can interfere with the packet’s calibrated humidity-control behavior.
Can I mix 72% Boveda with 69% packs?
No. Boveda recommends using only one RH level in a single humidor. Mixing different percentages can make the packs work against one another instead of maintaining one clear target.
Can Boveda packs touch cigars directly?
Boveda states that its intact packets are safe to place in contact with cigars. Do not cut or puncture the membrane, and follow the manufacturer’s storage instructions.
The Bottom Line
Boveda 72% RH Size 8 is a practical choice for small and travel humidors when you specifically need a higher RH target for a dry environment, a draftier container, or your preferred cigar-storage profile. Its strongest qualities are simple two-way humidity control and low maintenance, while its main limitation is that 72% is more specialized than the commonly used 69% option.
If you know 72% RH fits your setup and you need humidity control for a small-capacity humidor, this 10-pack is easy to recommend. If you have a well-sealed humidor, prefer a drier cigar, or need to manage a much larger collection, compare the other RH levels and pack sizes before deciding.
