Two-Way Humidity Control

Smart moisture

Right humidity.

Our packs absorb moisture when the air is too damp — and release it when the air is too dry. No refills, no distilled water, no guessing. Just drop one in and let it hold your exact relative humidity for months.

The Two-Way Difference

It reacts. You don't have to.

Ordinary products only add moisture — or only remove it. Inside every pack is a saturated salt solution that pushes the surrounding air toward one precise RH point, in whichever direction the air needs to go. That's what "two-way" means.

Too humid absorbs Too dry releases
Too Humid

The pack absorbs

When RH inside your container climbs above the pack's rating, the solution pulls excess water vapor out of the air — preventing mold, swelling, and spoilage.

Too Dry

The pack releases

When the air gets too dry, the same solution gives pure water vapor back — keeping cigars supple, wood stable, and herbals from turning to dust.

Choose by RH%

Every collection has its number.

Pick the pack rated for the humidity your contents actually need. Mixing? Start with the most popular level: 69%.

49% RH
Guitars, violins, ukuleles, pianos — keeps solid & laminate wood from cracking or swelling.
58–62% RH
Flower, herbal teas, and cured plant material — preserves terpenes, aroma, and texture.
65–72% RH
Standard humidor range. 65% for drier smoker's preference, 72% for long-term aging.
69% RH
The sweet spot for most humidors and general storage.
Most Popular
75% RH
Slow curing and long-term storage where maximum moisture retention is wanted.

Where It Shines

Built for what you're protecting.

Cigars

Hold 65–75% RH without distilled water, propylene glycol, or touching your hygrometer ever again.

Wooden Instruments

49% RH guards tops, bridges, and necks against the cracking-and-swelling cycle of seasonal air.

Herbal

58–62% RH keeps texture springy and terpene profiles intact — no crumble, no mold.

Tea & Food

Loose-leaf tea, dried fruit, brown sugar, spices — stay fresh, loose, and clump-free.

Dead Simple

Three steps. That's the whole job.

1

Choose your RH

Match the pack rating to what you're storing — 49% for instruments, 69% for cigars, 62% for herbal.

2

Drop it in

Place the pack inside any sealed container. On top of the contents, tucked in a corner — position doesn't matter.

3

Replace when hard

The pack slowly hardens as it's spent. When it feels rigid all the way through — typically 2–4 months — swap in a fresh one.

Questions

Frequently asked.

How long does one pack last?+

Typically 2–4 months in an airtight container, depending on how often it's opened and the ambient humidity. In tightly sealed, rarely opened containers, packs can last 6 months or more. When the pack hardens completely, it's time to replace it.

Can I use two different RH levels in one container?+

You can, but the levels will fight each other and settle somewhere in between. For consistent results, use only one RH level per container. If you're not sure which to pick, 69% is the most versatile starting point.

Do I ever add water to the packs?+

Never. The salt solution inside is precisely formulated at the factory. Adding water destroys the calibration. When a pack is spent, replace it — that's the entire maintenance routine.

Are the packs safe in direct contact with cigars, food, or instruments?+

Yes — the solution is food-grade and sealed inside a rugged, tear-resistant membrane. Many users place packs directly among cigars or tea leaves. If a pack is punctured and leaks, discard it and wipe the contents; the solution is non-toxic.

How many packs does my container need?+

Match total grams to container size: an 8 g pack covers a small jar (up to ~1 oz of contents), 60 g covers a 25–50 count humidor or guitar case, and 320 g handles large cabinets. More packs = faster recovery after opening, never over-humidification.

Do you offer wholesale and private label?+
