But before you take a look at our reviews, the list of specs below will help you understand more about what goes into the perfect gun safe dehumidifier.

Top Pick
The best gun safe dehumidifier for a long-term humidity solution is the GoldenRod, our top pick. This rod-style safe dehumidifier slightly heats and maintains the temperature of your gun safe to keep moisture at bay. No reheating or recharging required--just an outlet. The 12’’ GoldenRod covers 100 cubic feet, the 18’’ covesters 200 cubic feet, the 24’’ covers 300 cubic feet, and the 36’’ covers 500 cubic feet. That’s impressive! You can cover larger safes and other areas with just one tool. Each rod has a six-foot cord and includes mounting brackets and a plug attachment. Install the rod, run the cord out to the outlet, and cut off excess cord before attaching the plug for a perfect fit. The GoldenRods come with lifetime warranties, too! A rod dehumidifier involves a little work up-front to install, but it’s smooth sailing after that, and can give you peace of mind that your guns are safe in their safe!

SafeNDry Gun Safe Dehumidifier

The SafeNDry Gun Safe dehumidifier holds silica gel that helps to soak up moisture in the air, keeping it away from your guns and ammunition! It can dehumidify up to 60 cubic feet in an enclosed space to keep relative humidity below 30%. When the silica gel beads turn from dark blue to pink, that means they’re saturated and it’s time to dry them out in the oven. You can reuse this dehumidifier indefinitely! It works best for enclosed spaces with mild to moderate humidity issues. For basements and other areas with persistent humidity issues, a corded system that doesn’t need to be reset or charged may work best. In the proper setting, these silica gel canisters can last months or a year without needing to be recharged! It’s ideal for small safes and areas with basic humidity issues. This 450-gram canister doesn’t need batteries or electricity to keep your gun safe’s humidity low.

The Dry-Packs Silica Gel Dehumidifier is an easy, electricity-free way of keeping firearms from being affected by damp air.

The indicator beads can be set up in a clear “pocket” on the lid as an easy way to check whether it’s time to change out the dehumidifier and dry it out. The silica gel is formulated to be free of cobalt (II) chloride, a common color-changing indicator in silica dehumidifiers which has been linked to cancer in humans. When you’re starting to see green when you check on your dehumidifier, just pop the canister into the oven to reactivate them! If your ideal gun safe dehumidifier doesn’t require batteries or an outlet to work, this basic canister works well!

Barska 150G Dehumidifier

The Barska 150G dehumidifier is basically a “pillow” packed with silica gel that changes color as it absorbs more and more humidity. Compared to canisters, however, it has one big advantage: you can microwave it instead of heating it in the oven! “Recharging” the dehumidifier pillow so it can start soaking up moisture again takes about four minutes in a 600W microwave, versus a couple of hours for oven-baked canisters. The dehumidifier’s packet cover turns from blue to pink as it gets close to being saturated. The change covers the entire pillow cover, not just a small indicator area. Barska also makes safes, so they know what they’re talking about. Even contained dehumidifiers that recharge when plugged into an electrical socket can’t beat this pillow’s fast recharge time! No worries about spills, either. If you don’t want to constantly check on your dehumidifier or forget about it while it’s recharging, this option recharges fast!
