The Calinga humidifier is a humidification system featuring acrylic polymer crystals designed for cigar humidors. Transparent crystals Its principle is simple: the transparent crystals absorb distilled water, swell, and release humidity gradually and consistently into the enclosed space of your humidor. The transparent rectangular case, featuring three ventilation rosettes, simply rests in your humidor—on a tray, divider, or at the bottom, depending on available space. No plugs, no electronic mechanisms: the Calinga operates via passive evaporation. A discreet, efficient, and economical accessory that keeps your cigars in optimal storage conditions.
Polymer crystals: natural humidification
Acrylic polymer crystals (or superabsorbent crystals) are capable of absorbing up to several hundred times their weight in water. Immersed in distilled water, they swell and form a transparent gel. Placed in an enclosed environment like a cigar humidor, they slowly release humidity through evaporation via the case's perforations.
Unlike traditional sponges or foams that release their humidity inconsistently, polymer crystals offer gradual and stable diffusion. They are also less susceptible to mold as they do not constitute an organic medium favorable to bacterial growth—provided only distilled water is used, without additives.
Why choose the Calinga
💎
Transparent crystals
Natural and gradual humidification. The crystals swell with distilled water and gently release humidity, without sudden changes.
🚰
Distilled water only
No chemical solution, no propylene glycol. Distilled water from a supermarket is sufficient—the simplest solution.
📏
Compact rectangular format
Rests on a tray, a divider, or at the bottom of the humidor. Fits most desktop and travel humidors.
🔄
Hygrometric stabilization
The crystals regulate naturally: they release humidity when the air is dry and absorb it when it's too humid.
🫧
3 ventilation rosettes
Three circular diffusion zones optimize humidity distribution throughout the humidor's volume.
♻️
Indefinitely refillable
The crystals do not wear out—simply add distilled water when they shrink. A durable investment.
Simplicity for preservation
The Calinga doesn't pretend to be a decorative object—it's a discreet precision tool. Its transparent plastic casing blends into any humidor interior without distracting from the wood or cigars. The three concentric rosettes perforated on the top ensure balanced humidity diffusion along the entire length of the case.
Its elongated rectangular shape is designed to fit the internal dimensions of standard humidors. Placed at the bottom or on a removable tray, it takes up minimal space while offering a maximum diffusion surface. No wires, no batteries, no noise: the Calinga works silently, 24 hours a day, solely by the power of natural evaporation. It's the humidifier you install and forget about—until the next distilled water refill.
Setup in 4 steps
1
Immerse the crystals — submerge the Calinga in a container of distilled water for 30 to 60 minutes. The crystals will swell and become translucent.
2
Drain excess water — remove the Calinga and let any excess water drain for a few minutes. Wipe the outside of the case with a dry cloth.
3
Place in your humidor — lay the Calinga flat in your humidor, rosettes facing up. On a removable tray, a divider, or at the bottom—depending on available space.
4
Monitor and refill — check your hygrometer. When the crystals visibly shrink and humidity drops below 65%, re-immerse the Calinga in distilled water. Under normal conditions, a refill is needed every 2 to 4 weeks.

Universal compatibility — The Calinga is suitable for all cigar humidors with sufficient internal space to accommodate the case flat. It works in desktop humidors (20-100 cigars), spacious travel humidors, and cigar cabinets. For very small humidors (5-10 cigars), check that the case dimensions do not compress your cigars. One Calinga is sufficient for humidors up to approximately 50 cigars—beyond that, supplement with a second module or a complementary model.
Distilled water only — never tap water — Tap water contains limescale and minerals that clog the pores of the crystals and promote bacterial growth. Use exclusively distilled water, available at supermarkets for less than €2. Do not add any additives: no propylene glycol solution, no fragrance, no vinegar. Polymer crystals work with pure water, which is their strength and simplicity.

Never use propylene glycol solution — The Calinga's acrylic crystals work exclusively with distilled water. PG (propylene glycol) solutions are designed for foam humidifiers, not polymer crystals—they clog the pores and reduce absorption capacity. Do not use tap water, mineral water, or spring water either: limescale degrades the crystals and promotes mold.
🎁 The essential accessory for every humidor owner
The Calinga is the natural complement to any cigar humidor. Offer it along with a humidor for a complete gift—your recipient will only need to add distilled water for immediate cigar preservation.

Frequently asked questions
How do I know when to refill the Calinga?
Two indicators: visually, the crystals shrink and become smaller and drier when they have exhausted their water supply. On your hygrometer, a drop below 65% indicates it's time to refill. Under normal conditions (closed humidor, ambient temperature), expect to refill every 2 to 4 weeks. In summer or a warm environment, the frequency may increase.
Why use distilled water and not tap water?
Tap water contains limescale, chlorine, and minerals that accumulate in the crystals and gradually clog their pores. Eventually, the crystals lose their absorption capacity. Distilled water is chemically pure—it leaves no residue and does not promote mold growth. A 5-liter bottle costs less than €2 at supermarkets and lasts for several months of refills.
Can propylene glycol be used with the Calinga?
No, never. Propylene glycol (PG) solutions are designed for foam or sponge humidifiers, not polymer crystals. PG clogs the pores of acrylic crystals and drastically reduces their absorption capacity. The Calinga operates exclusively with pure distilled water—it is precisely this simplicity that makes it reliable.
Is the Calinga suitable for all humidor sizes?
The Calinga is suitable for desktop humidors (20 to 100 cigars), spacious travel humidors, and cigar cabinets. A single module is sufficient for humidors up to approximately 50 cigars. Beyond that, supplement with a second Calinga or a complementary model. For very small humidors (5-10 cigars), ensure the case does not compress your cigars inside.
How long does a Calinga last?
The acrylic polymer crystals do not wear out or degrade over time. They can be refilled indefinitely—simply re-immerse them in distilled water when they shrink. The case itself is made of durable plastic. Properly maintained (distilled water only, no PG, no tap water), a Calinga lasts several years without replacement.
Where should I place the Calinga in the humidor?
Place the Calinga flat, rosettes facing up, in a spot where it won't compress the cigars. Ideal locations: on a removable tray, on a cedar divider, or at the bottom of the humidor beneath the cigars. Avoid placing it directly against the cigars—leave a small space for humidified air to circulate freely. In drawer humidors, place it in the most accessible compartment to facilitate refills.
What is the difference between the Calinga and the Calinga Round?
Both use the same acrylic polymer crystals and operate with distilled water. The only difference is the shape of the casing: rectangular for the Calinga, rounded for the Calinga Round. Choose based on the space available in your humidor and the shape that best fits.
