One strange number after opening the lid does not tell you much. The trend matters more.

Your choice depends on climate, humidor seal, opening habits, and how your cigars burn after storage.

Some cigars stored at a lower RH may feel firmer and burn more easily. At a higher RH, some may feel softer or need more relighting. These results can vary by cigar, wrapper, room temperature, and storage time.

Boveda currently recommends 69% RH for general cigar storage. Treat it as a practical starting point rather than a rigid target for every smoker or humidor: 65% suits a drier preference, while 72% is intended for drafty humidors, dry environments, or a higher-moisture preference.

If 69% gives you a steady trend and the cigars feel and burn well, moving to 72% may not add any benefit. Higher is not automatically better.

To change your target, remove the old packs and install packs with the new RH. Do not use different RH levels together because they work toward different targets and reduce overall efficiency.

A hygrometer that reads several points high or low can lead to the wrong fix.

For example, it may show 64% when the actual humidity is higher. If you switch to 72% or add another humidifier, the cigars may become softer than you intended.

Calibrate the hygrometer first. Then record the reading for three to seven days under similar conditions. This is a practical tracking period, not a universal stabilisation promise. A new wooden humidor may need longer, and the product instructions should come first.

A reliable hygrometer is essential before you make any humidity adjustments. If you're unsure about your current meter, see our guide on how to choose the best hygrometer for a humidor.

The number depends on two facts:

The main Boveda pack sizes used for cigar storage are Size 8, Size 60, and Size 320.

Boveda’s current cigar guidance lists these common ratios:

Check the package before use because product instructions can change.

Here are three direct examples based on that guidance:

The calculation uses the humidor’s rated capacity, not only the number of cigars inside today. A 50-count humidor does not become a 10-count humidor because you currently store ten cigars in it.

Still, real use affects how fast packs work and how long they last. A loose seal, dry wood, or frequent opening can make them harden sooner.

If you do not know the rated capacity, check the maker’s product page or manual. Without the capacity and pack size, no one can give you a reliable fixed number.

If you're setting up or upgrading your cigar storage system, you can also browse MOZSLY cigar accessories to explore humidor and storage options for your setup.

A humidor’s fill level can affect airflow and how quickly the conditions change after opening.

An empty wooden humidor also leaves more wood exposed. If that wood is dry, it can pull moisture from the air and the packs.

Follow Boveda’s capacity guidance rather than cutting the number of packs because the box is half full. Boveda states that using extra packs with the same RH can improve efficiency and will not raise the target above the RH printed on the pack.

That said, space still matters in a small travel humidor. Do not force in extra packs if they crush cigars, bend wrappers, or block the lid.

Use the official capacity before judging from the outside. Trays, dividers, and thick walls can reduce usable space.

For a humidor from the MOZSLY Cigar Essentials collection, confirm the capacity and interior layout on its current product page or in its instructions. Then apply the Boveda ratio for the pack size you plan to use.

Boveda says its packs can safely touch cigars. You do not need to keep a large gap between the pack and tobacco.

Still, I would not leave a pack pinned under a tight row of cigars. Pressure can mark a wrapper, and a cramped layout may reduce airflow.

Try placing the pack:

In a large humidor, spread multiple packs across the storage areas.

During travel, keep the case out of direct sun and away from a hot car. Temperature affects RH readings, so a quick rise or drop after moving between a cool hotel room and a warm vehicle does not always mean the pack has failed.

Seasoning mainly applies to a new humidor with exposed wood inside.

A hard polymer, metal, or foam-lined travel case normally does not absorb moisture like unfinished wood. Follow the maker’s instructions rather than seasoning every case by habit.

Seasoning prepares dry wood. Daily humidity control maintains the environment after that preparation.

Many humidors use Spanish cedar because it can exchange moisture with the surrounding air. When the wood is dry, however, it may pull moisture from the box. That can make a Boveda pack harden quickly while the hygrometer remains low.

For a new wooden humidor, start by checking the maker's instructions. You can also follow our step-by-step guide on how to season a humidor before setting up your regular humidity-control system.

For a humidor already in regular use, you normally move straight to checking the hygrometer, seal, storage packs, and temperature.

Boveda’s current cigar guidance recommends replacing packs every three months for ongoing protection. Use that as a planning interval rather than waiting for a pack to become completely rigid.

Pack feel is still useful context. A firm spot around an edge does not necessarily mean the pack is spent. Check the whole pack at room temperature, and plan a replacement if it has lost most of its flexibility or the humidor’s RH trend is falling.

Climate, seal quality, wood condition, and opening frequency can affect how quickly a pack dries. Check the hygrometer and seal as well as the calendar.

Write the installation date on your phone, calendar, or the flat edge of the pack. This makes the three-month replacement point easier to track.

I usually check four areas:

This keeps the search simple and stops you from blaming the pack too early.

For a broader look at long-term RH control, see our guide to maintaining the perfect humidity in a cigar humidor, including the factors that can cause humidity to rise or fall over time.

After a change, record the RH and temperature once or twice a day for three to seven days. Take the reading under similar room conditions. If humidity keeps falling across that period, move to the next check.

If the reading remains too high after you've checked the hygrometer and temperature, see how to lower humidity in a humidor without making several changes at once.

If you change the RH, move the hygrometer, and add an electronic unit on the same day, the next reading will tell you very little.

For many small and medium humidors, Boveda can work as the only humidity source.
