Polymer sponge57 x 14 mmPack of 23 finishes
At the heart of every humidor is a discreet but essential accessory: the humidifier. Delivered in a pack of 2, the ROUND T75 combines everything you need 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 housing contains a polymer sponge that absorbs the humidification solution and then gradually releases it through a diamond-patterned perforated grille, ensuring even distribution throughout the humidor. Its slim design allows it to fit easily into most humidors, from desktop cases to larger models, resting on the cigars, secured under the lid, or installed in a dedicated compartment. Available in three finishes—Gold, Silver, and Black—it complements the style of your humidor, from light cedar interiors to more contemporary finishes. A simple, durable, and elegant accessory, it is ideal for replacing a worn-out humidifier or equipping a new humidor, and for preserving the freshness and aromas of your cigar selection over the weeks.

Understanding humidity
Why a cigar needs humidity
A cigar is made of tobacco leaves that react to the ambient air like a sponge: if it is too dry, it becomes brittle, burns too quickly, and loses its aromas; if it is too damp, it draws poorly, burns unevenly, and may develop 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, the tobacco retains its suppleness, burns evenly, and its aromas continue to harmonize.
This is the role of the humidifier: it contains a reservoir of water or humidification solution that it slowly releases into the humidor, compensating for the dry air that enters with each opening. Paired with a hygrometer, which measures the humidity level, it allows you to keep an eye on storage conditions and intervene at the right time. Cedar wood, which lines the interior of many humidors, also 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 domed edge, its grille forming a fine diamond lattice. Through the perforations, you can see the polymer sponge working silently. Resting on a bed of cigars or secured under a glass lid, it becomes a decorative feature in its own right.
The Gold finish matches the gold hinges and locks of classic humidors, Silver complements polished steel accessories, while Black blends into carbon fiber humidors or those with more modern lines. Three ways to decorate the interior of your humidor with style.
Putting your ROUND T75 into service
1
Moisten the sponge through the grille with distilled water or a suitable humidification solution until it is saturated without dripping.
2
Wipe off any excess from the housing with absorbent paper to prevent any direct contact between the water and the cigars.
3
Place the humidifier in the humidor, on the cigars, under the lid, or in its compartment, 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 onto your cigars, as excessive moisture can stain the wrapper or promote mold. After each refill, carefully wipe the housing. 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 an enthusiast who has just bought their first humidor, or for a connoisseur whose humidifier is showing signs of wear, the ROUND T75 is a useful and elegant gift at an affordable 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 you 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, the tobacco remains supple, burns evenly, and its aromas are fully expressed. Below this, the cigar dries out and becomes brittle; above it, it draws poorly and may mold. To find out where you stand, pair your ROUND T75 with a reliable hygrometer and take regular readings, especially during the first few weeks.
How do you refill the ROUND T75 humidifier?
Slowly pour distilled water or a humidification solution for cigar humidors over the grille, saturating the polymer sponge without overfilling it. Let it absorb for a few moments, then carefully turn the humidifier over and wipe off any excess with absorbent paper: it must never drip. Then place it back in the humidor. The refilling frequency depends on the season, the size of the humidor, and how often it is opened; your hygrometer will always tell you the right time to intervene.
Should you use distilled water?
Yes, distilled water is highly recommended. Tap water contains limescale, chlorine, and minerals that settle in the sponge, making it less effective and potentially promoting unpleasant odors in the humidor. You can also use a humidification solution specially designed for cigar humidors, often based on propylene glycol, which helps stabilize the humidity. In any case, avoid store-bought mineral or filtered water, which also contains mineral salts that can clog the sponge.
Where should you 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 rest it on the cigars, secure it under the lid if your humidor has a holder, or install it in a compartment designed for this purpose. Since humidity tends to drop, a high position promotes even distribution. Simply make sure the grille is not obstructed and that the housing is completely dry on the outside before placing it in contact with the cigars.
Which finish should you choose?
All three finishes offer exactly the same performance: only the appearance of the housing changes. The Gold finish naturally complements wooden humidors with gold hinges and classic styles. The Silver finish, with its polished shine, suits understated humidors and steel accessories. The Black finish blends discreetly into carbon fiber humidors, dark wood humidors, or those with modern lines. Simply choose the one that harmonizes best with the interior of your humidor and your other accessories.
Is one humidifier enough for my humidor?
For a standard-sized desktop humidor, a humidifier of this size is generally suitable. For a large humidor, or if you open it very often, a single unit may not be enough to maintain the desired humidity level. The best indicator remains your hygrometer: if the humidity struggles to rise above 65% despite regular refills, install the second humidifier from the pack. Otherwise, keep it in reserve for a second humidor or a travel case. Also remember to check the seal of the lid, as a humidor that does not close properly loses its humidity much faster.
How do you maintain the humidifier?
Always refill with distilled water or a dedicated solution to limit deposits. From time to time, inspect the sponge through the grille: if it shows traces of limescale, an unusual odor, or stains, it is time to clean it or replace the humidifier. Wipe the housing 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 prevent mold growth.
