Best Gun Safe Dehumidifiers Expert Reviews & Buying Guide


How to Pick Your Dehumidifier

Firearms do best in relatively dry storage conditions. In fact, high humidity levels may cause metal to rust and corrode, shortening the lifespan of your gun collection. We researched new and best-selling gun safe dehumidifier products to help you keep your firearms in perfect condition! 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.

Type

The main dehumidifier types are silica gel canisters and electric dehumidifiers that require recharging or a plug.

Coverage

The best gun safe dehumidifier for you depends on how big your safe is and how big the humidity problem is.

Wireless

Wired (corded) dehumidifiers don’t require recharging, but maybe more difficult to install. Wireless ones are easy.

Size

If you don’t have a lot of room to spare, compare the sizes of our dehumidifier picks to get one that’s compact!

Weight

Don’t overburden your shelving with a heavy dehumidifier. Weight can also be important if you want to mount a dehumidifier.

Warranty

A manufacturer may say their product will last a certain number of years, but a warranty really backs that up!

  • Weight: 0.43lbs
  • Warranty: 1 year

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!
