Polymer sponge57 x 14 mm3 finishes
At the heart of every cigar humidor lies a discreet yet essential accessory: the humidifier. The ROUND T75 combines everything needed to maintain an environment favorable to your cigars in a compact, round format, measuring just 57 mm in diameter and 14 mm thick. Its PVC case contains a polymer sponge that absorbs the humidification solution and gradually releases it through a perforated grid with a diamond pattern, ensuring even diffusion throughout the humidor. Its slim profile allows it to easily slip into most humidors, from desktop boxes to more generous models, whether placed on top of the cigars, attached under the lid, or installed in a dedicated compartment. Available in three finishes—Gold, Silver, and Black—it complements the aesthetics of your humidor, from light cedar interiors to more contemporary finishes. A simple, durable, and elegant accessory, ideal for replacing a worn-out humidifier or equipping a new humidor, and for preserving the freshness and aromas of your cigar selection week after week.

Understanding humidity
Why a cigar needs humidity
A cigar is made of tobacco leaves that react to the surrounding air like a sponge: if it is too dry, it becomes brittle, burns too quickly, and loses its aromas; if it is too moist, it draws poorly, burns unevenly, and risks developing mold. Enthusiasts agree on a relative humidity between 65 and 72%, combined with a stable temperature, ideally around 16 to 20°C. Within this range, tobacco retains its suppleness, its combustion remains even, and the aromas continue to harmonize.
This is the role of the humidifier: it contains a reservoir of water or humidification solution that it releases slowly into the humidor, compensating for the dry air that enters each time it is opened. Coupled with a hygrometer, which measures the humidity level, it allows you to keep an eye on storage conditions and intervene at the right moment. The cedar wood that lines the interior of many humidors acts as a natural buffer by absorbing and releasing moisture.

A jewel at the heart of the humidor
The ROUND T75 takes the shape of a medallion with a rounded edge, its grid featuring a fine diamond lattice. Through the openings, you can glimpse the polymer sponge working in silence. Placed on a bed of cigars or fixed under a glass lid, it becomes a decorative detail in its own right.
The Gold finish matches the hinges and locks of classic humidors, Silver goes well with polished steel accessories, while Black blends into carbon fiber humidors or those with more modern lines. Three ways to decorate the inside of your humidor consistently.
Setting up your ROUND T75
1
Moisten the sponge through the grid with distilled water or a suitable humidification solution until soaked, without it dripping.
2
Wipe away any excess on the case with paper towels to avoid direct contact between water and the cigars.
3
Place the humidifier in the humidor, on top of the cigars, under the lid, or in its slot, then close it.
4
Monitor the hygrometer and refill as soon as the humidity drops below 65%, generally every one to four weeks depending on the season.

Warning: never let the humidifier drip on your cigars, as excessive humidity can stain the wrapper or promote mold. After each refill, carefully wipe the case. A single humidifier may not be enough for a very large humidor: monitor your hygrometer and adjust if the humidity remains too low. Avoid tap water, which clogs the sponge.
An essential accessory to give as a gift
For a hobbyist who has just treated themselves to their first humidor, or for a connoisseur whose humidifier is showing signs of fatigue, the ROUND T75 is a useful and elegant gift, at a small price. Choose the finish that matches their humidor: gold for classic humidors, silver for a sleek style, black for contemporary models.

Frequently asked questions
What humidity level should I aim for in a cigar humidor?
Enthusiasts generally aim for a relative humidity between 65 and 72%, with a stable temperature, ideally around 16 to 20°C. Within this range, tobacco remains supple, combustion is even, and the aromas are fully expressed. Below this, the cigar dries out and becomes brittle; above, it draws poorly and risks molding. To know where you stand, pair your ROUND T75 with a reliable hygrometer and check the reading regularly, especially during the first few weeks.
How do I refill the ROUND T75 humidifier?
Slowly pour distilled water or a humidification solution for humidors onto the grid to soak the polymer sponge without saturating it. Let it absorb for a few moments, then gently turn the humidifier over and wipe away any excess with paper towels: it should never drip. Then, place it back into the humidor. The frequency of refilling depends on the season, the size of the humidor, and the number of times it is opened; your hygrometer will always indicate the right time to intervene.
Should I use distilled water?
Yes, distilled water is highly recommended. Tap water contains lime, chlorine, and minerals that settle in the sponge, making it less effective and potentially promoting unwanted odors in the humidor. You can also use a humidification solution specially designed for cigar humidors, often based on propylene glycol, which helps stabilize humidity. In any case, avoid commercial mineral or filtered water, which also contains mineral salts that can clog the sponge.
Where should I place the humidifier in the humidor?
Thanks to its compact size of 57 x 14 mm, the ROUND T75 fits into most humidors. You can place it on the cigars, attach it under the lid if your humidor has a bracket, or install it in a compartment provided for this purpose. Since humidity tends to drop, a high position promotes good distribution. Just make sure the grid is not blocked and the case is completely dry on the outside before placing it in contact with the cigars.
Which finish should I choose?
All three finishes offer exactly the same performance: only the appearance of the case changes. The Gold finish naturally matches wooden humidors with gold hinges and classic settings. The Silver finish, with a polished shine, is suitable for understated humidors and steel accessories. The Black finish is discreet in carbon fiber, dark wood, or contemporary humidors. Simply choose the one that best harmonizes with the interior of your humidor and your other accessories.
Is one humidifier enough for my humidor?
For a standard-sized desktop humidor, one humidifier of this size is usually sufficient. For a large humidor, or if you open it very often, a single unit may not be enough to maintain the desired level. The best indicator remains your hygrometer: if the humidity struggles to rise above 65% despite regular refills, add a second humidifier. Also, remember to check the seal of the lid, as a humidor that does not close well loses its humidity much faster.
How do I maintain the humidifier?
Always refill with distilled water or a dedicated solution to limit deposits. From time to time, inspect the sponge through the grid: if it shows traces of lime, an unusual odor, or stains, it is time to clean it or replace the humidifier. Wipe the case with a soft, dry cloth. If you do not use your humidor for a long period, let the humidifier dry completely before storing it to avoid any mold development.
