Integra Boost Humidity Packs: RH Levels, Sizing & Use
Integra Boost packs are 2-way humidity control packs that hold a cigar humidor at one exact relative humidity, adding moisture when the air is dry and pulling it back when the air is damp. They're the main alternative to Boveda, built around a glycerin-based salt solution instead of Boveda's saturated-salt formula, and every pack ships with a color-change indicator card so you can see pack life at a glance instead of guessing.
This guide covers how Integra Boost works, which RH level to pick, how to size packs to your humidor, and when the indicator card tells you it's time to swap.
How Integra Boost's 2-way humidity control works
Integra Boost is a true 2-way pack: it releases moisture when the air inside your humidor is too dry and absorbs it when the air is too damp, holding the box at one rated RH instead of just adding moisture and hoping. The chemistry is a glycerin-based salt solution sealed in a permeable membrane — a different formula from Boveda's saturated-salt design, but the same core mechanism of self-correcting in both directions.
Because it's 2-way, an Integra Boost pack can't overshoot its rated humidity the way a soaked sponge or floral foam can. You set the level once and the pack does the rest, without a fan, batteries, or a refill schedule.
Choosing your RH level: 55, 62, 65, 69, or 72%
Integra Boost sells cigar-relevant packs at 55%, 62%, 65%, 69%, and 72% RH. Most cigar smokers start at 69%, the same balanced middle ground most humidor guides recommend, and adjust from there based on how their cigars feel.
- 65% gives a firmer, slower, cooler burn — a good fit for humid climates or smokers who prefer a drier draw.
- 69% is the all-around default most smokers settle on.
- 72% runs softer and moister — useful in very dry climates or for smokers who like a fuller draw.
- 55% and 62% sit below the cigar range and are meant for cannabis and other lower-RH storage, not premium cigars.
Don't mix RH levels in the same box — packs at different ratings pull the air toward an average and waste capacity. For the full tradeoffs between RH levels, see our cigar humidity guide.
Sizing Integra Boost packs to your humidor
Integra Boost ships in several gram sizes, from small 4–8 gram packs up to 60–67 gram packs and large-format packs for bigger boxes. Match pack mass to your humidor's air volume and cigar count, not just the box size on the shelf.
A travel case or small jar (up to about 15 cigars) is usually fine with a single small pack. A 25–75 count desktop humidor typically needs one to two of the 60–67 gram packs. Larger desktops and small cabinets in the 75–150 range generally need two to four packs, and anything bigger should be sized up until the humidity reading holds steady rather than drifting. When unsure, add another pack — extra capacity doesn't push humidity higher, it just means the packs last longer. Pair Integra Boost with a well-sealed cigar humidor and confirm your actual reading with a digital hygrometer, since no humidity pack fixes a leaky box.
The indicator card: how to know when to replace a pack
Every Integra Boost pack includes a small color-change indicator card, which is the single biggest practical difference from Boveda. When the pack is fresh and still working, the card reads white or green. As the pack nears exhaustion, it shifts to orange or pink — a clear visual signal instead of squeezing the pack and guessing by feel.
Check the card whenever you open your humidor. Once it turns orange or pink, plan to replace that pack within the next week or two rather than waiting for your hygrometer to show a problem — by the time the reading drops, the cigars have already been sitting below target for a while.
Integra Boost for cannabis storage
Integra Boost's 55% and 62% packs are built for cannabis and other lower-RH storage, not cigars — cigars want the 65–72% range covered above. If you store cannabis alongside cigar gear or use tobacco-leaf wraps, our cigar wraps for weed guide covers which RH level pairs with leaf wraps specifically.
Where Integra Boost is sold (and what it costs)
Integra Boost is sold almost exclusively online — cigar lounges and tobacconists stock Boveda far more often, so don't count on finding Integra Boost on a shelf if you run out mid-session. A 4-pack of 60-gram packs typically runs $8–$10, a dollar or two cheaper than the Boveda equivalent. If you order supplies online anyway, that's a real, if small, saving over time.
Integra Boost vs. Boveda: which one?
Integra Boost and Boveda both hold a set RH reliably, so the decision usually comes down to two things: the indicator card versus the squeeze test, and online-only ordering versus wide retail availability. Our full Boveda vs. Integra humidity packs comparison walks through accuracy, recharge options, and price side by side if you're still deciding between the two.
FAQ
How long do Integra Boost humidity packs last?
Typically two to six months, depending on how well your humidor seals, your climate, and how often you open the lid. A leaky humidor burns through packs faster than a well-sealed one. Watch the indicator card rather than guessing — it turns orange or pink well before the pack is fully spent.
Can I use Integra Boost humidity packs for weed?
Yes. Integra Boost sells 55% and 62% RH packs specifically for cannabis and other lower-humidity storage, separate from the 65–72% range built for cigars. Use the RH level matched to what you're storing — a 69% cigar pack will over-humidify cannabis, and a 62% cannabis pack will under-humidify cigars.
How do I know when to replace an Integra Boost pack?
Check the built-in indicator card. It reads white or green while the pack is still working and turns orange or pink as it nears exhaustion. That color change is the whole point of Integra Boost's design — you don't need to squeeze or weigh the pack to know it's time to swap.
Is Integra Boost better than Boveda?
Neither is clearly better overall — the right pick depends on what you value. Integra Boost's indicator card removes the guesswork on replacement timing and it's slightly cheaper per pack; Boveda has wider retail availability and a marginal accuracy edge in independent tests. See our Boveda vs. Integra comparison for the full breakdown.
Conclusion
Integra Boost is a reliable 2-way humidity pack for cigars, with one standout feature: the color-change indicator card that tells you exactly when to replace it, no guessing required. Pick your RH (65, 69, or 72% for cigars), size enough packs for your humidor's capacity, and swap them when the card turns orange or pink. Use the Humidor Tracker to log pack replacement dates and get a reminder before your next pack runs dry.
