A humidor is a box built to keep cigars fresh. It holds a steady humidity level so your cigars don't dry out, and a good one will keep them in smoking shape for months or years. If you're new to cigars, this is the piece of gear that protects everything else you buy. Here's how it works and how to set one up. If you're unsure of any humidor terminology please feel free to reference our glossary of cigar humidor terms.
Why cigars need a humidor
A cigar is rolled tobacco, and tobacco is happiest at a specific moisture level. Leave a cigar out in a dry room and it loses its oils within days, which makes it burn hot and taste harsh. Store it too wet and it gets tight, tunnels when you smoke it, and can grow mold. A humidor keeps cigars in the narrow window where they stay springy, burn evenly, and taste the way the maker intended. Most cigar smokers aim for about 65 to 70 percent relative humidity and a temperature around 65 to 70 degrees.
The parts of a humidor
Every traditional humidor comes down to a few pieces working together.
The box itself is sealed wood, usually lined with Spanish cedar. The cedar holds moisture, adds a pleasant aroma, and helps keep tobacco beetles away. The humidification source adds moisture, whether that's a two-way pack, a gel or bead unit, or an electronic humidifier. The hygrometer is the gauge that tells you the humidity inside, either analog or digital. Put simply, the box holds the environment, the humidification keeps it wet enough, and the hygrometer lets you check that it's working.
How a humidor works
Once seasoned, the cedar and the humidification source keep the air inside at your target humidity. The cedar buffers small swings by absorbing moisture when it's high and releasing it when it's low, while the humidification source keeps the overall level topped up. You glance at the hygrometer now and then, refill or replace the humidification when it drops, and otherwise leave your cigars alone to rest. Electric humidors add automatic humidity and temperature control, which we compare in electric vs. traditional humidors.
How to season a new humidor
A brand-new wood humidor is dry, and if you load cigars right away the cedar will pull moisture straight out of them. Seasoning fixes that. Here's the simple version.
- Wipe the interior cedar with a cloth lightly dampened in distilled water. Use distilled only, never tap water.
- Place a small dish of distilled water inside, or drop in a seasoning pack made for the job.
- Close the lid and let it sit. Over two to seven days the cedar absorbs moisture and the interior climbs toward 65 to 72 percent.
- Once the hygrometer holds steady in that range, add your humidification source and load your cigars.
That's it. Season once, and the box is ready to protect cigars for years.
Keeping it stable
After setup, a humidor is low effort. Check the hygrometer every week or two, keep it out of direct sun and away from heat vents, and refill or swap the humidification when the level drops. If you open it constantly or live somewhere very dry, you'll refill more often. That's normal.
FAQ
What humidity should a humidor be? Most cigar smokers keep it around 65 to 70 percent. Some prefer a touch lower for a firmer smoke. Anywhere in the mid to high 60s is a safe target.
Do you need distilled water? Yes. Tap water has minerals that can cause mold and clog humidification units. Distilled water only.
How long does it take to season a humidor? Usually two to seven days for a desktop box, and up to a week for a cabinet. Don't rush it.
Can you use a plastic container instead? A sealed plastic container with a humidification pack, sometimes called a Tupperdor, will keep cigars fresh in a pinch. It won't have the cedar or the look of a real humidor, but it works as a starter or overflow.
