It’s the most cost-effective cigar storage upgrade out there, a no-nonsense setup that delivers cabinet-level performance for a fraction of the cost. With steady humidity control and room to grow, a well-built coolidor protects your cigars, preserves flavor, and keeps your collection ready to enjoy.
Think of it as the blue-collar humidor: practical, reliable, and built for cigar lovers who value performance over polish. You still honor the ritual, the aroma of Spanish cedar, and the satisfaction of caring for your cigars, you just do it with more capacity and less fuss.

A coolidor is exactly what it sounds like, a cooler turned into a humidor. It’s the most cost-effective way to store a growing cigar collection without spending cabinet money. The thick, insulated walls and gasketed lid create a stable environment that can rival any traditional humidor. Add some Spanish cedar, a reliable humidification device, and you’ve built a roomy, low-maintenance system that holds humidity like a pro.
Because a cooler resists temperature swings, cigars inside experience fewer humidity fluctuations and age more evenly. Pair it with a calibrated hygrometer and a few Boveda packs, and you’ll get the same environment found in high-end humidors, without the high-end price tag.
Coolidors have become a favorite among collectors, veterans, and enthusiasts alike because they combine simplicity with serious performance. You don’t need a walk-in humidor or a climate-controlled cabinet to care for your cigars, just a little cedar, the right tools, some attention to detail, and some effort.
For cigar lovers who value consistency, a coolidor offers three big wins: capacity, control, and cost. The cooler itself is inexpensive, and a few repurposed Spanish cedar cigar boxes make perfect trays and spacers. That means more cigars stored safely, better airflow, and less maintenance.
Wooden humidors look great in the living room, but they demand seasoning, rehydrating, and constant care. A coolidor? Wipe it down, add cedar, drop in your humidity packs, and close the lid. Done. It’s the cigar world’s version of “set it and forget it”, a workhorse that performs without drama.
When planning how to build a coolidor, think beyond size, consider layout, airflow, and how you’ll organize your cigar boxes. A 28–48-quart new cooler fits most home collections, but if you age boxes or share with friends, go bigger. More storage space means steadier humidity and smoother air circulation when storing cigars long-term.
Whenever possible, buy new. Old coolers tend to carry that plastic scent you never want near premium cigars. If you must use an older one, plan time to neutralize the odor before use.
Look for:
A tight-sealing gasketed lid to lock in humidity.
Smooth interior walls (no drain plugs or deep grooves).
A light interior color so you can read your hygrometer easily.
Bonus points for handles or wheels, because eventually, you’ll want to show off what’s inside your cigar collection.
Before loading cigars, preparation matters. Wipe every surface with a clean cloth dampened in distilled water, then let the cooler air-dry completely for a few hours.
If a plastic smell lingers, place a dish of baking soda and a small plate of dry coffee grounds inside. Close the lid for a few days, that combo erases odors better than any cleaner and removes unwanted smells without chemicals.
And never use a plastic bag as a liner. It traps moisture, creates condensation pockets, and throws off your humidity levels. A clean, breathable interior gives your cigars the best environment for aging without risking too much humidity or mold.
These aren’t luxury items, they’re the essentials trusted by cigar lovers who’ve outgrown traditional humidors and want a better environment for storing cigars long-term.
Before diving in, take a few minutes to gather your setup. Building a coolidor isn’t complicated, but the right tools make all the difference between a quick DIY project and a setup that performs like a professional cedar humidor.
Slats, dividers, or empty cigar boxes, cedar regulates humidity and adds that rich, unmistakable aroma cigar lovers crave.
Boveda packs are the gold standard: low effort, high consistency. Silica beads, an electronic humidification unit, or other options also work if you prefer more control.
To monitor your humidity control and temperature control with precision.
For setup, wiping, and occasional refreshes. Skip warm water or any additives, pure distilled keeps your environment clean and consistent.
Pro Tip: More cedar is always better. It transforms a simple plastic cooler into a true humidor environment, clean, aromatic, and reliable.
Now comes the fun part, building your setup. A coolidor isn’t about fancy tools or endless tweaking; it’s about doing it right once. With a little patience and the right layout, you’ll have a system that keeps humidity balanced and cigars aging beautifully.
Lay two cedar slats or empty boxes on the bottom to create air channels. This simple foundation improves air circulation and prevents your cigars from resting directly on plastic.
Place cigar boxes or trays on top so your smokes never sit flat against the cooler. This barrier prevents too much humidity and allows your cigars to breathe evenly.
Distribute Boveda packs or a vented container of silica beads throughout the cooler, never just one in the middle. Even distribution helps you maintain humidity and ensures every box benefits equally.
Close the lid and let the system rest for 24–48 hours while monitoring humidity. Aim for 65–69% relative humidity, the range where flavor and performance align.
Keep it simple. Once stable, your cigars are ready to store and age for long periods without worry.
Most cigars thrive between 65–69% humidity. Delicate Connecticuts prefer the lower end; oily maduros do better near 69.
Focus on consistency. Check your hygrometer daily for the first few days, then weekly. If humidity dips, add another Boveda pack; if it rises, remove one or add dry cedar. Make small, patient adjustments. Let the system stabilize, good storage rewards patience.
Segment your cooler. Keep daily smokes near the top and aging cigars deeper where conditions change more slowly.
Run dual setups. Use one cooler at 65% for cigars in rotation, another at 69% for long-term aging.
Use “sacrificial cedar.” Line the bottom with empty boxes to absorb plastic off-gassing.
Adopt a quarantine habit. Rest new arrivals in a secondary cooler before introducing them to the main stash.
Refresh stubborn odors. Use the baking-soda-and-coffee combo again if needed.
Once your coolidor is dialed in, consistency is everything. Think of this less as maintenance and more as good cigar stewardship, a little attention goes a long way toward keeping your collection in perfect shape.
Check humidity weekly at first, then monthly once things stabilize. Replace Boveda packs when they stiffen and recharge silica beads only with distilled water. Keep the lid gasket clean, wipe down the interior every few months, and don’t overcrowd your boxes, airflow matters more than volume.
Checking your hygrometer, rotating boxes, and keeping your coolidor clean isn’t just maintenance, it’s part of the ritual. That quick glance at steady humidity is a reminder that patience pays off, and your next perfect smoke is waiting.
The beauty of a coolidor is that when it’s built right, it’s boring, in the best possible way. No drama, no wild swings, just smooth performance that lets you focus on what really matters: enjoying your cigars.
Even simple setups can go sideways if you overlook a few basics. Here’s what to avoid, mand how to fix it fast.
Using open water cups or sponges: They invite mold and make it easy to over-humidify. Stick with Boveda packs, silica beads, or another controlled humidification device that keeps moisture steady.
Overcrowding boxes: When air can’t move, humidity can’t stay even. Think layers and trays, not piles.
Adding scented materials or wipes: Anything perfumed, even “cedar-scented” sprays, will ruin your cigar’s natural aroma. Keep it clean, keep it neutral.
Exposing to heat or direct sunlight: Sudden temperature swings can dry cigars or over-humidify them in hours. Find a stable spot and let insulation do its job.
Most humidors fail because of neglect, not bad design. Whether you’re using a cedar humidor, cabinet, or cigar coolidor, the goal stays the same, stable humidity, steady airflow, and cigars that light perfectly.
A cedar humidor brings tradition, presentation, and that classic cigar-lounge look.
A coolidor delivers practicality, space, and unmatched stability per dollar.
And a cabinet humidor gives you large-scale control for serious aging or high-volume collections.
Most cigar lovers end up with both worlds, a display humidor up front for show, and a coolidor tucked away quietly handling the real work. Together, they make a perfect balance between form and function.
Quick fixes for common issues:
Plastic smell? Repeat the baking soda and coffee routine for several weeks if needed.
Humidity drop? Add another Boveda pack or recharge your beads with distilled water.
Too humid? Pull one humidity pack or add dry cedar.
Traveling? Skip ice packs, condensation can crack wrappers before you even light up.
If you notice unwanted smells or inconsistent readings, let your setup breathe for a few hours, wipe it with a damp cloth, and recalibrate. Small tweaks are all it takes to protect cigars and keep your system reliable.
Never use harsh cleaners inside your cooler. Even mild residue can cling to plastic and overpower your cigars’ natural oils and aroma. Stick with a clean cloth and distilled water only, no warm water, sprays, or soaps.
Keep your cedar lining raw and unfinished, no varnish, no glue. Anything treated can off-gas chemicals that compromise your premium cigars.
At the end of the day, boring is good. Stable humidity, steady temperature control, and predictable airflow mean your cigars will light clean, burn straight, and taste exactly as the blender intended.
Before wrapping up, let’s answer some of the most common questions cigar lovers ask about building and maintaining a coolidor. Whether you’re starting from scratch or fine-tuning an existing setup, these answers cover everything you need to keep your cigars aging perfectly.
Usually 24–48 hours. Once the hygrometer holds steady, you’re good to start loading cigars.
Between 65% and 69% relative humidity. That’s where draw, burn, and flavor stay balanced for most cigars.
Yes, as long as they’re unscented and silica-based. Always recharge with distilled water, never tap water.
No. Plastic doesn’t absorb moisture, so a wipe-down with distilled water and a few humidity packs is all it takes.
Not for most builds. Passive humidifiers like Boveda or beads are plenty unless you’re managing a large cabinet-style setup.
Use baking soda and dry coffee grounds inside with the lid closed for a few days, then wipe with distilled water.
Absolutely. Just stack them on cedar rails and allow airflow between boxes for even humidity.
A 28–48-quart cooler suits most cigar enthusiasts. Larger coolers help maintain steadier conditions for long-term aging.
Not precise control, just consistency. Keep your coolidor away from direct sunlight and temperature spikes for best results.
Building a coolidor is one of the simplest, most effective cigar upgrades you can make. With a few supplies and a little patience, you’ll have a scalable storage solution that protects your investment and keeps every stick ready to burn perfectly.
Storing and protecting your cigars in a homemade coolidor is about creating an equal, if not better environment that rivals the best humidors. With the right humidification unit, cedar boxes, and patience, your coolidor becomes the ultimate setup for both single cigars and full boxes.
