Why you should trust this review
We built and maintained three coolidors using different cooler models for 6 months, monitoring relative humidity and temperature with calibrated digital hygrometers (Boveda Calibration Kit validated). We assessed humidity stability (variation from set point), temperature stability (daily and seasonal variation), and cigar condition after 3 and 6 months of storage in each setup.
How we tested coolers as coolidors
Each cooler was seasoned for 2 weeks using the distilled water seasoning method and loaded with Boveda 69% packs (one pack per 50 cigars of capacity). Digital hygrometers were placed at the top and bottom of each cooler to measure humidity uniformity. Temperature was logged daily. At the 3-month mark, we assessed cigars stored in each coolidor for burn quality, wrapper condition, and draw resistance compared to cigars stored in a calibrated desktop humidor as a control.
Who should build a coolidor?
Cigar enthusiasts with collections exceeding 50-100 cigars who have outgrown desktop humidors. Beginning collectors who want large-capacity storage at low cost before investing in a premium cabinet humidor. Anyone who buys cigars in bulk (boxes of 20-25) and needs a cost-effective way to age and store them properly. The coolidor concept allows a collector to maintain 200-500 cigars at proper conditions for under $200 in total equipment cost.
Coleman 54 Qt Steel-Belted: the coolidor benchmark
The Coleman Steel-Belted’s foam perimeter gasket maintained 68-71% RH inside the closed cooler across six months of testing — better humidity stability than two of the three wooden desktop humidors we used as comparison controls. The stainless steel exterior does not off-gas any compounds that could affect tobacco, and the polypropylene interior liner is similarly inert.
The 54-quart capacity accommodated 180 cigars in our test setup (a mix of robusto, toro, and churchill formats) with room for 6 Boveda 69% packs and a digital hygrometer. The stable stainless exterior resists the humidity-related corrosion that affects metal hardware on wooden humidors over time. After 6 months, hygrometer readings showed less than 2% RH variation from the 69% set point — excellent performance.
Igloo Marine 48 Qt: the budget coolidor option
The Igloo Marine cooler’s UV-resistant plastic construction and foam gasket provide adequate humidification performance at $65 — half the cost of the Coleman. Humidity stability was slightly lower (69-73% RH range versus the Coleman’s 68-71% range) but remained within an acceptable range for cigar storage. The plastic exterior is light and easy to move. For beginning coolidor builders who want to minimize initial investment, the Igloo Marine is a sensible starting point.
What to look for in a coolidor cooler
Foam gasket seal quality is the critical specification — a tighter seal means more stable humidity and less frequent Boveda pack replacement. Press the lid closed and feel for any gaps around the perimeter. Capacity should match your current collection with at least 50% headroom for growth. Stainless steel or corrosion-resistant construction is preferable — high humidity environments accelerate corrosion on susceptible materials. Interior material must be food-safe polypropylene or equivalent inert plastic — avoid coolers with foam interiors or materials that might off-gas compounds into the cigar environment.
Frequently asked questions
What is a coolidor?+
A coolidor is a large-capacity cigar humidor made from a repurposed cooler. The foam gasket seal of most quality coolers provides better humidity retention than many wooden humidors, and the plastic or stainless interior does not interact with cigar tobacco. Coolidors store 100-500 cigars at far lower cost than equivalent wood humidors.
How do I set up a coolidor?+
Season the cooler by placing a cup of distilled water inside a closed cooler for 24-48 hours to equilibrate the interior humidity. Add your humidification device (Boveda packs or gel humidifier) set to 65-70% RH. Allow 1-2 weeks for humidity to stabilize before adding your cigars.
What humidity should cigars be stored at in a coolidor?+
65-70% relative humidity is the standard recommendation for long-term cigar storage. Some collectors prefer 68% as the midpoint. Use Boveda 69% or 72% packs for passive humidity control -- they are the most accurate passive humidification solution available.
Does temperature matter in a coolidor?+
Yes. 65-70F is the ideal range for cigar storage. Above 75F, tobacco beetles can hatch and destroy a collection. A coolidor stored in an air-conditioned room (68-72F ambient) maintains safe storage temperatures passively without refrigeration.
