Types of Gun Safe Dehumidifier

Gun safe dehumidifiers come in two primary types: desiccant dehumidifiers and electric dehumidifiers. 

Your choice between the two types depends on your specific needs, the size and location of your gun safe, and the availability of an electrical source. Both types of dehumidifiers are effective in protecting your guns from rust and corrosion caused by moisture.

Desiccant Dehumidifiers

desiccant as dehumidifier for gun safe

These types of dehumidifiers use a desiccating (drying) agent to absorb moisture from the air. The most common desiccant used is silica gel, known for its high absorption capacity. Desiccant dehumidifiers don’t require a power source to operate, making them ideal for safes without an electrical outlet nearby. 

Once the desiccant is saturated with moisture, it can usually be renewed by heating (often in an oven) to drive off the absorbed moisture, allowing the dehumidifier to be reused. They’re often available as canisters or bags filled with the desiccant material.

Electric Dehumidifiers

Electric dehumidifiers work a bit differently. Instead of absorbing moisture, they reduce humidity by warming the air inside the safe, causing the air to hold more moisture and thereby reducing condensation on your firearms. 

These devices usually come in two styles: rod-style dehumidifiers and electrically powered units that circulate air. Rod-style dehumidifiers are a popular choice for gun safes. They are easy to install, require little maintenance, and provide a constant heat source that keeps the interior of your safe at a higher temperature, reducing humidity levels. 

On the other hand, electrically powered units that circulate air work like mini air conditioners, cooling and heating the air to maintain a constant, low humidity level. They usually come with a built-in humidistat to regulate humidity levels.

How We Chose & Must-Have Features

Our selection process was as meticulous as a seasoned sniper taking aim. Here’s what we prioritized:

Volume Covered

Size matters when it comes to dehumidifiers. We looked for options that can adequately cover the interior of a gun safe.

Size

As paradoxical as it may seem, we wanted compact units that can do a big job. Space is a premium inside gun safes.

After all, you want plenty of room for all of your toys!

Safety Features

Safety comes first. All of our picks have features to prevent overheating and other potential hazards. 

Durability

Nobody likes buying the same thing twice. We favored dehumidifiers that are built to last.

Low Maintenance

Let’s face it, nobody wants another chore. Our chosen safe dehumidifiers require minimal upkeep.

Power Options

We made sure to include both electric and non-electric options just in case power is a problem in you safe. 

Price

We all have budgets. So, we made sure to include products that provide the best bang for your buck.

The Afloia Mini punches above its weight class, and your firearms will thank you for it.

Afloia Mini Gun Safe Dehumidifier

It’s incredibly energy efficient, meaning you can keep it running 24/7 without fear of spiking your electricity bill. It’s like having a vigilant, round-the-clock guardian for your gun safe, minus the outrageous costs.

  • No continuous drainage option
  • It relies on electricity

Scores: 4.5/5

What customers say

“I have a small safe and this lasted a lot longer than I expected. Easy to recharge and when you get done charging put it in a zip lock bag after it cools for a bit. That was the only downside I noticed was an airtight bag to put them in, but that’s an easy correction.”

– Howard

Best Electric Rod Dehumidifier: Browning Ever Dry Electric Rod

The Browning Ever Dry takes the electric road to perfection. Easy to install and equipped with an automatic shut-off for safety, it’s a hotshot when it comes to keeping your gun safe dry.

The Browning Ever Dry stands tall with its stellar performance. This electric device works by gently heating the air in your safe, ensuring moisture stays on the down-low. It’s like a cozy little fireplace for your firearms, keeping them snug and rust-free.

And don’t worry about fiddling with settings or adjustments. The Ever Dry takes the guesswork out of maintaining your safe’s climate. Just plug it in and let it do its thing. It’s as simple as it gets.

But what really sets it apart is its safety features. It comes equipped with an automatic shut-off function, preventing overheating and giving you that extra peace of mind. 

Browning Electric Gun Safe Dehumidifier Electric Rod

Installation? Easy-peasy! The Browning Ever Dry comes with detachable feet for easy mounting. You’ll have it up and running faster than you can say “humidity.”

Size-wise, this rod is a space saver. Its slender design slips into your gun safe without hogging up precious room. Plus, its sleek appearance isn’t bad to look at either. It’s like the supermodel of dehumidifiers – slim, attractive, and always ready for action.

Pros

  • Helps keep humidity levels low
  • Comes with detachable feet for quick and hassle-free mounting
  • Space-saving design
  • Requires very little maintenance

Cons

  • Doesn’t have a built-in humidity sensor
  • Requires a power source to function
  • May produce heat which may be an issue in already hot environments

Scores: 4.5/5

What customers say

“This is an excellent product, I’ve had it about a month. It came quickly, and it is as described. Used in a safe, the power cord can be threaded through a small hole: the plastic cap on the power cord end pulls off the metal tube and the flexible heating element can be removed. Pull the plastic cap carefully over the flexible heating element and remove it.

From the outside of the safe, feed the flexible heating element into the safe through a small hole (I put a rubber grommet into the hole to preclude the metal safe from abraiding the power cord); once inside the safe, carefully slide the plastic cap back on, over the flexible heating element and onto the power cord (the end of which is now outside the safe);

I put a small overhand knot in the power cord between the plastic cap and the heating element to keep the power cord from pulling out of the device. Slide the heating element and power cord knot into the metal tube and replace the plastic cap; plug it in and you’re done. Easy, simple, effective.

I put mine on the floor of the safe since heat rises. The device is “hot” but not too hot to touch or move; just uncomfortable to hold. I put a thermometer in my safe and it appears the temperature is about two degrees above ambient.”

Best Canister Dehumidifier: SnapSafe Reusable Canister Dehumidifier

The SnapSafe Canister Dehumidifier is like a moisture magnet in a tin can. This zero-power device can be easily renewed in an oven and goes back to work, again and again, making it a top contender.

Another standout feature is that it requires no electricity. This makes it an excellent choice for safes located in areas without a nearby power outlet. It’s a plug-free, eco-friendly solution for your humidity woes.

The beauty of this dehumidifier lies in its simplicity. It’s filled with moisture-absorbing desiccant, which silently draws dampness from your gun safe like a magnet. The result? Your firearms enjoy a cozy, dry environment, free from the clutches of corrosion and rust.

SnapSafe Reusable Canister Gun Safe Dehumidifier

One of the SnapSafe Canister’s standout features is its reusability. Once the desiccant inside becomes saturated, you don’t need to replace it. Instead, you simply heat it in an oven to dry it out and it’s good to go again. It’s the dehumidifying gift that keeps on giving!

But don’t mistake its simplicity for lack of power. The SnapSafe Canister Dehumidifier has a moisture capacity that’s hard to beat, making it ideal even for larger safes.

Best Plugin Dehumidifier: Browning Flexible Dehumidifier

With the Browning Flexible Dehumidifier, dampness doesn’t stand a chance. Simply plug it in, and its flexible design allows it to reach any corner of your safe.

One of the major perks of the Browning Flexible is in its name – it’s flexible! Its design allows it to bend and twist, fitting into the nooks and crannies of your gun safe that other dehumidifiers might miss. This ensures an even distribution of heat, effectively controlling humidity throughout the safe.

Its moisture-removing prowess is all thanks to its electric functionality. By subtly warming the air, it increases the air’s ability to hold moisture, reducing condensation and banishing dampness from your safe. This is vital for preventing rust and other moisture-related damage to your firearms.

Browning Safes Flexible Everdry Electric Dehumidifier for gun safes

When it comes to setup, this plugin champ is a dream. With no complicated assembly or installation, it’s ready to start its mission as soon as you are. Plug it in, place it in your safe, and it’s good to go.

Pros

  • Flexibility makes it easier to install
  • Fits into a variety of safe sizes and shapes
  • Efficiently controls humidity by warming the air inside the safe
  • Designed to prevent any overheating or fire risk

Cons

  • Slight heat emission
  • Doesn’t come in multiple lengths

Scores: 4.1/5 

What customers say

“First & foremost – the heating element (thicker part) on this item is 18″ long. You won’t find that anywhere else. This allows the item to be curved around a corner or through various obstacles in your gun safe, esp. compared to the hard rods.

The Second most important fact – is it has a red led light that turns on when the item is plugged in and functioning. The solid rods don’t have that. nice to know it is actually on!! Installation was easy with the removable plug. My old safe didn’t have a hole for the cord – but it was easy to drill through the safe to install it. I HIGHLY RECOMMEND THIS ITEM.

You won’t find any deals on it anywhere – so just buy it here. It’s a great way to get more dehumidifying power into your gun safe when only a smaller rod would fit and obstruct space. DON’T BUY THE RECHARGEABLE plug in pellet dehumidifiers – those were a waste for me – and always turned pink within hours of being recharged to blue!!”

– Russell R. Herman

Most Versatile Gun Safe Dehumidifier: Goldenrod Original Dehumidifier

The Goldenrod Original is a chameleon. Its slim design allows it to fit anywhere, and its mounting brackets make it a breeze to install.

  • Lifetime warranty

Cons

  • No auto-shutoff when optimal humidity is reached
  • Requires a power source

Scores: 2.8/5

What customers say

“I am using one of these in a vehicle stored in a garage that is not climate-controlled, where it tends to stay humid. Last year, both stored vehicles developed a small amount of mold on surfaces that are frequently touched (steering wheel, door handles.) I cleaned all surfaces prior to storage this year, and added the 18″ GoldenRod raised just above the front drivers side floor.

Initially I was skeptical that the mild heat source would make a difference. I was glad to see that vehicle had no signs of surface mold after storage this season, while the other stored vehicle developed a little mold again. The GoldenRod itself is not fancy, but is solidly constructed and comes with a tool-less vampire tap plug, if removal is needed to fish cord through small hole.

A Kill-A-Watt meter confirmed the specified 1 watt per inch rating, drawing about 18 watts on mine. I will most likely order another for the other vehicle and tool chest.”

– Matthew Yarema

Best Rechargeable Silica Gel: Eva-Dry Renewable Mini Dehumidifier

A zero-power hero, the Eva-Dry Renewable is filled with silica gel crystals that absorb moisture. When they’re saturated, simply plug in the device to renew the crystals. It’s a true set-it-and-forget-it solution.

Now, here’s where it gets really cool. The Eva-Dry is renewable. When its silica gel crystals have soaked up all the moisture they can handle, you don’t throw it out. Nope, you plug it into an outlet and let it dry out, ready to be used again. It’s like a dehumidifying phoenix rising from its own damp ashes. This reusable feature is not just eco-friendly but also easy on your pocket in the long run.

Eva-Dry Renewable Mini Gun Safe Dehumidifier

Another plus is its compact and wireless design. It can easily fit into any safe, big or small, with no power cords to worry about. Just place it in your safe and let it get to work.

Its indicator window is also a game-changer. It changes color to tell you when it’s time to renew the silica gel. No guesswork, no trouble. It couldn’t be easier to use.

Pros

  • Silica gel can be used repeatedly
  • Color indicator when the unit needs to be recharged
  • Compact and wireless
  • Doesn’t require electricity to operate

Cons

  • You’ll need to have an outlet nearby to recharge it
  • Limited range

Scores: 4.3 /5

What customers say

“I put this in our busiest bathroom. I don’t use the hook–I propped the dehumidifier on its long end on a shelf. Wish it had a built-in stand (or flat bottom), but it works just fine as it is out of the traffic zone.

It takes about 5 days for the crystals to turn from orange to dark olive green. I LOVE that I can flip out the plug and plug it into an outlet. It takes several (5?) hours to dry out the crystals completely so it’s ready to use again. Yes, it does get warm when drying out–no big deal. It won’t burn you.

Glad I got it. Only complaint is that, when plugged in, it takes up a lot of space. Don’t plan to use other outlets around it, as they will likely be blocked.”

– Joe Mama

What customers say

“I bought this to install in my Liberty Safe. I didn’t see any signs of moisture, but I had that smell from the fabric liner that seemed to be getting worst. After 2-weeks of having this Rod installed the smell leveled off. I installed a Hydrometer and my immediate reading was 58% humidity.

Now it’s stabled out at a little over 49%. I installed it along the bottom front of my door opening. I had to add an extension cord to make it reach the outlet in the back of the safe, but it was an easy, straight forward install.”

– Larry L. Jordan
