Integra Boost 4 g at 62% RH holds a sealed container at a steady 62% relative humidity — not by adding moisture, and not by taking it away, but by doing whichever the container needs at the time. One pack covers up to 14 g (half an ounce), which is a small jar or a pouch. The blend is 100% salt-free plant-based glycerin and water, FDA compliant and safe in direct contact, so nothing crystallises onto what it is sitting against. A Replacement Indicator Card is included so you are never guessing whether it is still working. Stocked in Sydney and shipped domestically.
Two-way is the whole point
A desiccant only takes moisture out. A humidifier pack only puts moisture in. Either one will overshoot, because conditions in a jar change every time you open it, every time the room warms up, and as the contents themselves settle.
Integra Boost works in both directions. If the container is drier than 62% RH the pack releases moisture into it; if it is wetter, the pack absorbs. The result is a flat line rather than a sawtooth, which is what preserves texture, aroma and weight over weeks and months rather than days.
Salt-free, and that matters more than it sounds
Many humidity packs work on a salt solution. They do control humidity, but if the membrane is pressed against your contents, salt can crystallise onto them — and once that happens the damage is done.
Integra Boost uses a proprietary blend of plant-based glycerin and water with no salt at all. It is FDA compliant, printed with food-grade ink, non-toxic and biodegradable, and the membrane is spill and tear resistant. That combination is why the pack can sit straight in with the contents rather than needing to be kept apart from them.
How to use it
There is not much to it, but a few habits make a real difference to how long a pack lasts and how well it holds:
| Step | What to do |
|---|---|
| Match the size | One 4 g pack per 14 g of contents. Larger containers simply take more packs — two packs for double the contents, and so on. |
| Use a sealed container | Glass jars with a gasket, sealed pouches or lidded tubs. The pack can only govern an enclosed space; in a container that breathes it will work itself flat trying to condition the room. |
| Start at roughly the right point | Integra Boost holds a level, which is its strength. Get the contents to about where you want them first, then let the pack keep them there and even out the last of it. |
| Drop it straight in | No barrier needed — salt-free and food-contact safe means it can rest against the contents. Leave the pack sealed; do not cut or open it. |
| Watch the card | Keep the Replacement Indicator Card in the container. When the dot turns bright blue, the pack is spent and it is time for a fresh one. |
| Store spares wrapped | Unopened packs keep for two years from manufacture in their wrapper. Once a pack is out of the wrapper it is working, so open them as you need them. |

FAQ
Which size do I need?
One 4 g pack covers up to 14 g of contents. The 8 g pack covers up to 28 g if that suits your containers better. For anything larger, use more packs rather than stretching one — a single pack in an oversized container will exhaust itself quickly and hold the level less reliably.
How long will a pack last?
The manufacturer's answer is anywhere from a couple of months to a full year, and the spread is genuine rather than vague: a jar opened daily in a dry room works a pack far harder than one that sits sealed in a cupboard. That is exactly why the indicator card is included — it tells you the answer for your situation instead of you working from an average.
Can it touch the contents directly?
Yes, and that is one of the advantages of the salt-free formulation. The pack is FDA compliant and safe for direct contact, and because there is no salt in it there is nothing to crystallise onto whatever it is resting against. Just leave the pack intact — it is not meant to be opened.
Will it rescue something that is too wet or too dry?
It is a regulator rather than a rescue, and it is worth knowing that so you get the best from it. Bring the contents to roughly the right condition first — a drying rack is the usual way — and Integra Boost will take it the rest of the way and then hold it there indefinitely. Used that way it is excellent; asked to move a long way on its own it will simply exhaust itself.
Can I recharge or reuse it?
No — the classic Boost packs are single-use, and you replace the pack once the indicator turns blue. The upside is that it holds its stated 62% consistently for as long as it has capacity, with no guesswork about whether a recharge has taken.
Why 62%?
62% RH is the setting most people land on for keeping dried material supple and aromatic without being damp enough to invite mould. Integra make other levels — 55% for anyone who prefers a firmer, drier result — and both sit within the accepted range. 62% is the one we stock because it is what most customers ask for.
Is this genuine Integra Boost?
Yes. We stock the genuine Desiccare product, held in Sydney and shipped domestically, so you are not waiting on an overseas parcel or wondering what arrives. If anything is not right with an order, you are dealing with us here.
