Best Gun Safe Dehumidifiers Reviewed

We have reviewed & compared the best gun safe dehumidifiers on the market. Rods and rechargeable models are covered in our guide.

Keeping guns is your right; keeping them safe and cared for is your responsibility. One of the best ways to do this is to have a gun safe. But just because the safe keeps your guns and ammo safe from prying eyes or fingers doesn’t mean they are fully protected.

High humidity inside your gun safe can promote mold growth, rust, corrode your guns and make your ammo worthless. The best investment you can make is a gun safe dehumidifier. This article will explain why, show you what to look for, and offer up the best gun safe dehumidifiers around.

Why a Gun Safe Needs to Be Dehumidified

Gun safes need care and maintenance, just like anything else in our homes. Humidity is one of the biggest issues when dealing with gun safe maintenance. Different temperatures inside the safe and outside can lead to condensation if the humidity isn’t controlled.

Condensation can lead to rust, corrosion, and even mold. Generally, when high humidity is present, the ammunition is the first to be affected. High humidity can degrade ammo to the point that it is no longer usable.

Next are the guns themselves. Triggers, springs, barrels, and other internal parts can begin to rust when exposed to the air’s moisture. You can’t forget about the safe itself, either. Moisture can damage the metal plating, eat away at the foam insulation and rust the screws that hold the gun mounts in place.

Using a gun safe dehumidifier is the best method of preventing all of this from happening. They are affordable, easy to install, and with the right model, virtually maintenance-free.

Choosing the Right Dehumidifier for your Gun Safe

Dehumidifier Type

The first thing to think about is what kind of dehumidifier you want. There are three basic types of dehumidifiers broken down into two primary categories.


Desiccant is a moisture absorbing material. For the most part, silica gel is used because it has high absorption properties and is relatively inexpensive. There are two types of desiccant used in dehumidifiers, standard, and rechargeable.

Standard desiccant is found in sheets or packs, much like the small “Do Not Eat” packages found in your shoes and electronics boxes. These has a limit as to how much moisture they can absorb before they need to be replaced.

Rechargeable desiccant styles use a heating pad to dry out the silica gel to be reused repeatedly. Of course, these types must be plugged in and offer a higher initial cost.

Electric Dry Rod

Electric dehumidifiers for your gun case come in the form of a dry rod. This is a glass tube around a mineral, usually Vermiculite. The electric rod is heated, and the warm air rises and circulates inside the gun safe preventing condensation and lowering the relative humidity.

These models will either need to be plugged in or run on batteries. If you choose the battery option, you will need to replace the batteries as they run out.

Coverage Area

One important aspect is to measure the space in the safe and the capacity of the dehumidifier. You want to ensure your humidifier can cover the size of your gun safe. These smaller capacity dehumidifiers are generally measured in cubic feet.

Once you have the gun safe measurements, you can then compare it to the capacity size listed for the dehumidifier model you are looking at.

Moisture Absorption Capacity

While dry rod dehumidifiers may not have an actual capacity for moisture collection, desiccant models do. You will need to know when the desiccant needs to be dried out or replaced so you can maintain the proper level of humidity at all times.

Indicator System

One of the best ways to tell is to use a dehumidifier with an indicator system. These systems can let you know when the desiccant needs attention, when the humidity is too high or too low or if there is a problem.

Not every model will offer an indication system, but the added cost is well worth it for those that do.

Dehumidifier Lifespan

Because these are smaller units, not all of them will last forever. There are a few models on our list below that offer a lifetime warranty, but you won’t be able to keep them around forever for desiccant models.

The true lifespan of any dehumidifier will depend on care, maintenance, and the amount of use. For a gun safe dehumidifier, though, you should expect several years to a lifetime for the dry rod models and between 3 and 10 years for the desiccant dehumidifier.

Ease of Installation & Use

Installation may be more difficult, depending on the type of dehumidifier you choose. For the most part, desiccant models are the easiest. You simply place them in the gun safe and close the door.

However, if the desiccant is rechargeable, it will require an outlet, as will the electrical dry rods. For this, you may need to drill a hole in your safe to fit the plug through. This can increase the difficulty of the installation since gun safes aren’t easy to get into.


Warranties will vary with each model, and you need to understand what is covered. Some warranties won’t cover the silica gel, for example, while others will. For the most part, the term of coverage is the most important part.

You will find that warranties vary from 1-year to a lifetime. Make sure you know what coverage terms your brand and model offer. Also, make sure you read about making a warranty claim. Some warranties require things like registration, professional installation, proof of purchase, or even paid shipping.

Understand what you are getting into when it comes to the warranty before you buy.


Your budget is the final concern. For the most part, these dehumidifiers are competitively priced and shouldn’t pose a burden for most budgets. However, there are a few models that can get expensive.

While you may be tempted to go with the highest-priced model thinking it is the best, it may be better to get a model you can easily afford that will get the job done.

9 Best Gun Safe Dehumidifiers Reviewed

1. Lockdown GoldenRod

Best Gun Safe Dehumidifier Rod
Gun Safe Dehumidifier Type Electric rod
Coverage Area 100 cubic feet
Voltage 110-120 v
Dimensions 12-inches long

Lockdown’s GoldenRod gun safe dehumidifier is arguably the best dehumidifier out there. It is the model that is the highest-selling, most reviewed and sought after. It comes in various sizes to accommodate many different types and sizes of gun safes and has features that make it easy to use.

The heating element inside produces a warming effect that doesn’t rise much above 100 degrees. The insulating DDE field and glass tube do get hot to the touch, but if you must move it while heated, an oven mitt will suffice.

The 6-foot cord isn’t all that long but offers you a quick-disconnect feature that allows you to drill a smaller hole (if your safe doesn’t have one) and plug it in once the cable is run.

This model will mount on the floor of your safe or the lowest shelf. The heat will rise and circulate with the cooler air in the safe. This effect lowers the humidity some but helps more to prevent condensation.

This model will accommodate gun safes up to 100 cubic feet. However, there are various sizes available. The 18, 24, and 36-inch models will protect gun safes up to 200, 300, and 500 cubic feet, respectively.

One of the best features, though, is the lifetime warranty. Should anything ever go wrong with your dehumidifier rod, you can get a replacement or a repair for as long as you own the device.


  • Lifetime warranty
  • Breakaway cord for easier installation
  • Multiple sizes available
  • Highly affordable
  • Fits virtually any gun safe


  • Does get hot to the touch
  • Power cord may be too short


Best Dehumidifier for Gun Safe in Garage
Gun Safe Dehumidifier Type Electrical heating
Coverage Area 300 cubic feet
Voltage 110-120 v
Dimensions 9 x 7 x 4 inches

PEET makes a corner stand dehumidifier for your gun safe that works best in the garage. This model offers some interesting features and uses heat-controlled air circulation to combat condensation and moisture accumulation.

This model is a heated air unit that takes in cooler air from the bottom of the machine, heats it and pushes it out of the top. The result is a warm, dry environment inside your garage mounted gun safe.

The electrical draw is minimal and will cost you about as much as an incandescent bulb does each year. The power cord, though, is both a highlight and a low point for this particular model.

The cord and plug come unassembled to make routing easier for you. You can drill a much smaller hole to only fit the wire through (if your safe doesn’t have a hole already). Once through, you need to strip the wire and assemble the plug.

The problem is that the actual plug isn’t made of the best quality. Arcing, sparks, and tripping circuit breakers is common. However, you can buy a better quality plug and use that instead for a couple of dollars.

Once the plug is sorted, though, there are little problems at all with this dehumidifier. It runs quietly and doesn’t get hot to the touch. It also comes with a 5-year warranty, as long as you register within 10 days of purchase.

Upon registration, you receive 30-days to return the dehumidifier for a full refund. After the first month, the rest of the 5-year warranty kicks in. However, if you do not register within 10 days of purchase, the warranty is void.


  • 5-year warranty (30-day money back)
  • Quiet operation
  • Circulates warm air on its own
  • Ideal for garage mounted safes


  • AC plug is poorly designed
  • Must register warranty within 10 days

3. Dry-Packs

Best Desiccant Gun Safe Dehumidifier
Gun Safe Dehumidifier Type Recharging desiccant
Coverage Area Approx. 50 cubic feet
Voltage N/A
Dimensions 4.5 x 4.5 x 6 inches

Dry-Packs offer you the best desiccant dehumidifier for your smaller gun safe. These canisters do not need an electrical current and can be recharged to work again and again for years to come—simple and effective dehumidifying.

The canisters are about 6 inches tall and will fit in most gun safes with ease. It is advised to install them near the bottom to middle of the safe, if possible. However, if you only have space at the top, you can put them there, too.

The canisters use two types of silica beads. The white beads make up the bulk of the canister and are not dyed nor contain cobalt. They absorb about 60% of their weight in moisture. The orange colored beads are there as an indicator to recharge.

When the colored beads (there is only about a cap full) turn dark green, it means it is time to recharge the canister. You do this by baking them directly in your oven or convection oven. Do not use in the microwave, though!

Depending on the temperature and relative humidity, the recharge takes between 3 and 6 hours per canister. Baking at about 275 to 300 degrees will dry out the beads and return the indicators back to orange. Once cooled, you can place them back in the safe. The beads will last several years worth of recharging.

While there isn’t a warranty, you do have 30 days to return them if you aren’t happy with the results. Just keep in mind these aren’t designed to actively remove humidity as there isn’t a fan to draw air into the cans.


  • No electricity needed
  • Recharge silica in the oven
  • Will last several years
  • Indicator beads tell you when to recharge
  • Can use multiple cans in the same safe


  • 30-day return
  • Doesn’t actively reduce humidity

4. Eva-Dry E-333

Best Cordless Gun Safe Dehumidifier
Gun Safe Dehumidifier Type Recharging desiccant
Coverage Area About 50 cubic feet
Voltage 110-120 v (recharge only)
Dimensions 5 x 6 x 1.5 inches

Eva-Dry also presents you with a desiccant dehumidifier; however, this one can recharge itself (with your help) and doesn’t require your oven. However, it doesn’t absorb as much moisture as some other models on this list.

Like the Dry-Packs, this uses silica beads that are dyed to change colors as they absorb moisture. The beads will start orange (not blue, which is an indicator that cobalt was used, and is bad for the environment). As they collect moisture, they will turn green.

Once the beads are green, you simply remove the pack from the safe and plug it into an outlet or extension cord. There is a folding plug on the back of the unit for this reason. Inside is a small heating element that will use the electricity to heat the beads and remove the moisture.

It is best to do this in a well-ventilated area or even outside so you don’t return the moisture to the room with the safe. Once the beads turn orange again, you unplug it and place it back into the safe where it will start the process all over again.

This model will absorb about 6 ounces of moisture over about 30 days. This will depend on the ambient temperature and relative humidity in your safe, though.

There isn’t a warranty, but you can return the unit for a refund within 30 days. However, at the price point and the fact you can hang it anywhere, you won’t need to return it. You should note, though, that the recharge time is about 12 hours. Make sure you have the safe sealed tight during the recharge period to help maintain lower humidity.


  • No cords or batteries needed
  • Plugs directly into an outlet to recharge
  • Can absorb as much as 6 ounces per month
  • No cobalt in silica beads


  • 30-day return only
  • May not work well in larger spaces

5. Hornady 95900

Best Rechargeable Gun Safe Dehumidifier
Gun Safe Dehumidifier Type Recharging desiccant
Coverage Area 333 cubic feet
Voltage 110 (to recharge)
Dimensions 4 x 6 x 1.5 inches

If you buy ammo, you have heard of Hornady. This dehumidifier is easily the best rechargeable desiccant dehumidifier for gun safes. It has mounting options and recharges when needed to keep your guns and ammo moisture-free.

This small box is sleek and well designed using a red and black color scheme to make it even more eye pleasing. However, one of the best features is the mounting options. You can lay this box flat on the floor or shelf of your safe, prop it up in a corner or use the included quick-connect mounting bracket.

As long as you can easily view the bead window, you will know when it is time to recharge. In the past, charging was a major issue. The original run of this model has a problem with the plug area that would cause the internal wires to come loose and sometimes allow the silica beads to fall out.

However, those issues, according to Hornady, have been addressed. The recommended recharge time is about 10 hours. However, because the silica beads use cobalt to turn from blue to pink, it can take much longer. In most cases, you should expect to leave the unit plugged in overnight for up to 24 hours to get them back to as blue as possible.

The dehumidifier does come with a 1-year warranty, so you can get a replacement if there are any problems. It is also advised to buy two to use in alternating charging conditions. For the price, it is a good recommendation.


  • Lay flat, prop on shelf or mount with hanger
  • Viewing window indicator for recharging
  • Works in large safes up to 300 cubic feet
  • No batteries or power cords needed


  • 1-year warranty
  • May take longer than stated to recharge
  • Does contain cobalt

6. Liberty Safe Dehumidifier

Best Electric Gun Safe Dehumidifier
Gun Safe Dehumidifier Type Electric dry rod
Coverage Area up to 500 cubic feet
Voltage 110-120 v
Dimensions 12 or 18 inches long

Liberty Safe makes some of the best residential gun safes in the world. It is no wonder that they also create a great dehumidifier rod to protect those safes and your guns. This electric dry rod will heat up the air and prevent condensation.

Within a few hours of use, you will notice a difference. This rod warms up to about 100 degrees, allowing warm air to rise and slowly circulate around your safe. The warm air lowers the humidity over time and prevents condensation from forming on your ammo and gunmetal.

To mount the rod, you need to run the power cord wire through the safe (drill a hole if needed) or use an internal outlet if your safe is equipped. You will need to put the plug together, but it is a simple process and pretty well built.

Once the power is ready, the mounting brackets screw into the bottom of your safe. However, the included screws are fine thread and not very long. It is highly advised that you purchase longer wood or even sheet metal screws for a more secure mounting.

The rod does get hot to the touch. It won’t ignite cloth, fabric, or even paper, but it can scald skin, so take precautions when using or moving in and out of the safe. With a 5-year warranty (1-year for refurbished), your investment is protected, just like your guns.


  • 5-year warranty
  • Easy to assemble and install
  • Warms to between 100 and 120 degrees
  • Works in as little as 3 hours
  • 12 or 18 inch sizes available


  • Mounting hardware is low quality
  • AC plug may come apart

7. Pro Breeze

Best Mini Dehumidifier for Gun Safe
Gun Safe Dehumidifier Type Recharging desiccant
Coverage Area 333 cubic feet
Voltage N/A
Dimensions 7 x 6 x 2 inches

The Pro Breeze dehumidifier is also a rechargeable desiccant type. It doesn’t use batteries or power cords and can easily be transported wherever you need it. In a gun safe, it is the best mini dehumidifier you can buy.

The silica gel beads are dyed for color identification. However, there isn’t any cobalt here, so the beads are the green (when wet) and orange (when dry) colors. Recharging is easy as well. Once the beads turn dark green, they are about 60% full, which is about all they can hold.

Simply remove the dehumidifier from the safe and plug it into an outlet. The recharge process will take about 10 to 12 hours, though, so be prepared for that. Ideally, you will have 2 boxes and can swap them out, so you are never without a dehumidifier in your safe, especially in high humid areas.

These boxes don’t spill and have a compact, space-saving design. You can use them anywhere, too, not just your gun safe. They work well in RVs, cars, and even your gym locker. Wherever you need to control humidity to limit moisture, mold and mildew growth, a Pro Breeze is a simple and affordable answer.

The best part, though, is that unlike many other desiccant style dehumidifiers, this one comes with an actual warranty. It is only for 12-months, but that is a lot better than no warranty or a 30-day refund warranty.


  • No batteries needed
  • Saves space and is portable
  • Non-toxic silica beads
  • Can use multiple units in a single safe


  • 1-year warranty
  • May need to recharge weekly

8. SnapSafe 75902 Safe Dehumidifier

Gun Safe Dehumidifier Beads
Gun Safe Dehumidifier Type Canister desiccant
Coverage Area About 100 cubic feet
Voltage N/A
Dimensions 4 x 5 x 4 inches

Another canister model comes from SnapSafe. SnapSafe, if you aren’t aware, is a subsidiary of Hornady, makers of some of the finest ammunition around. They know a thing or two about humidity control and its effects on ammo and guns.

This canister is a 5-inch diameter, and like the Dry-Packs canister, it will indicate through color changing beads when it is time to recharge. The good thing about this canister, though, is that it recharges really fast. At just about 2 hours in your oven (at 300 degrees), the silica beads will be ready to absorb more moisture from your safe.

You will need to recharge at least once a month. High humidity areas may need to do so every couple of weeks. Once you get used to checking the indicator beads, you will be able to work out a schedule to maintain the canister’s absorbency.

The lifetime warranty protects against defects and craftsmanship of the canister; it will last you a very long time. Silica beads of this type don’t generally wear out, and you can recharge and reuse them for decades.


  • Lifetime warranty
  • Recharges quicker than most other models
  • Lasts for years
  • Affordable option
  • Doesn’t use batteries or electricity


  • Can require frequent recharging
  • Lid may be loose during shipping

9. Browning Ever Dry Electric Rod

Made in the USA
Gun Safe Dehumidifier Type Electric dry rod
Coverage Area Up to 500 cubic feet
Voltage 110-120 v
Dimensions 24-inches long

Rounding out our list is the made in the USA Browning Ever-Dry electric rod dehumidifier. This model is similar to the other dry rods on the list and performs well in any safe. There is one size to choose from, the 24-inch rod. It works in gun safes up to 500 cubic feet.

The rod will heat to 120 degrees and offers the safe environment a warm, dry air circulation. As long as you mount this on the floor, your entire safe will experience the warmer, dry air without worry of condensation or high humidity levels.

Like most other dry rod units, you will need to run the power cord through the safe. Unless your model has an internal outlet, this may affect the safe’s fire rating, so make sure you make the hole as small as possible.

Once you run the power cord, you can mount the unit to the floor using the included hardware. This hardware is strong enough that you don’t need an extra purchase, but some do choose longer screws.

The worst part about this model is the 90-day warranty. That is a bit dismal for the dehumidifier type and should be a lot better. However, once you have the dehumidifier up and running, you shouldn’t experience any issues. The 90-days is plenty to determine if there is an issue or not.


  • Heats to 120 degrees
  • Mounts are stable
  • Plug works for any internal or external safe outlet
  • Mount and forget with near-zero maintenance


  • 90-day warranty
  • Only one size to choose from

What Causes Gun Safe Moisture Problems

There are a lot of factors that go into giving gun safes humidity and moisture problems. One of the biggest factors is the safe’s location. Keeping them safe in a garage or basement will elevate humidity levels the most.

You also need to factor in the ambient temperature around the safe and the humidity levels in the home. These will come into play where condensation is concerned and are affected by how often you access the safe. The less often the safe door is opened, the more controlled the humidity levels will be inside.

How to Install a Gun Safe Dehumidifier

Installing a gun safe will depend on what type you purchase and how it receives its power. Battery powered models and non-rechargeable desiccant types, for example, only need be placed inside the gun safe (battery models need to be turned on, obviously).

You will need to get the power cord to an outlet for electrical types and rechargeable desiccant models. Usually, this will entail drilling a hole to fit the power cord through.

Once you have the hole and the cord is run through, you will want to seal the hole, usually with a clear, waterproof caulk. This will prevent moisture and humidity changes outside the safe from affecting the inside.

Dry rod models should be placed at the bottom of the safe. As the hot air they create rises, it will circulate with the colder air, raising the temperature and preventing condensation while also lowering the relative humidity.

More Tips to Help Reduce Humidity in Gun Safes

The best way to reduce and maintain humidity levels in your gun safe is through the use of a gun safe dehumidifier. This will offer the most moisture absorption and humidity control inside the safe.

There are other methods, of course, though they aren’t as capable as a dehumidifier.

  • Light bulbs and heating pads.
    Using the same method as a dry rod dehumidifier, light bulbs, and heating pads will raise the air temperature to combat condensation.
  • Gel packs, rice, baking soda.
    These three methods aren’t permanent solutions, but each will absorb moisture from the air. You will need to replace them frequently, though.
  • Damp Rid and Moth Balls.
    Both commercial products are designed to remove moisture from the air. They cost a little more than the other options, but you can buy them in bulk.

People Also Ask (FAQ)

What size dehumidifier do I need for my gun safe?

The size of your gun safe will determine the size dehumidifier. You need to measure your gun safe in cubic feet (Length x Width x Height). Once you have that number, you can match it up with the capacity rating of the dehumidifier. If you are on the capacity line, you will want to go with the size bigger instead of the size smaller.

Can I make a DIY gun safe dehumidifier?

You can make a DIY gun safe dehumidifier. However, it isn’t recommended. Just as too much humidity can cause damage, too little can as well. DIY dehumidifiers (other than using baking soda or rice) can absorb too much moisture as they are difficult to control. It is best to use natural methods or buy a dehumidifier specifically made for gun safes.

How often should I change my gun safe dehumidifier?

If the dehumidifier stops working, breaks down, or has a refrigerant leak, it is time to replace it. If your model is still under warranty, you can make a claim to have your unit repaired or replaced. If it is out of warranty, it is best to buy a new one. Generally, dehumidifiers for gun safes will last between 5 and 15 years. Some dry heat rods will last much longer.

How do I charge a rechargeable gun safe dehumidifier?

Recharging your dehumidifier will depend on the type you are using. To recharge silica gel, for example, you only need to use the heating pad to dry out the gel. If you use a refrigerant based dehumidifier, though, you shouldn’t ever need to recharge the refrigerant. If you do, it is likely because of a leak. The dehumidifier should be checked and repaired or replaced by a licensed professional.

Where is a good place to buy these units?

One of the best places to buy a gun safe dehumidifier is through Amazon. They will have the largest selection, best prices, and even specials or deals based on the brand or model. You can also shop locally at gun shops, sporting goods stores, or even home improvement shops. Aside from Amazon, shopping at Dick’s, Home Depot, or Lowe’s will be your best bet at finding the right model for you.


Finding the best gun safe dehumidifier can be challenging. You need to decide on the type, power source, and size capacity before you can pick one to buy.

Hopefully, this article gave you some insight into choosing the best model and which ones to shop for. If you are still in doubt, check out our top pick, the Lockdown GoldenRod. This model comes in various sizes and will work in almost every gun safe there is, including yours.
