You reach for your guns in the gun safe. It’s been a long time since you showed ‘em who’s the man.

As the goons confront you, you point your gun at them and say ‘Halt! Or I’ll shoot.’ At your surprise, instead of fearing you, they just wave off your threat over a laugh.

Why? Your guns are just a show-off now. They’re rusted and coated with molds and mildews. Only if you had the best gun safe dehumidifier installed, you wouldn’t end up falling to such an embarrassment.

I’m covering the top ones available in the market including fantastic dehumidifiers like Lockdown Silica Gel with Rechargeable Beads.

This one comes with the versatility and functionality you need. Apart from this durable beast, I’m also bringing to you all-new picks that will boggle your mind.

8 Best Gun Safe Dehumidifier Reviews

Do you want to keep your guns in pristine condition, and free of rust and mold? This post is designed to help you eliminate guesswork when searching for a top-quality option.

After spending months on end testing and analyzing the performance of different products, here are the best 8 that we handpicked.

1. Lockdown Silica Gel Can: Best Rechargeable Gun Safe Dehumidifier

If you need to keep the contents of your safe free from rust, mold, and mildew, one of the best dehumidifiers you can use is the Lockdown silica gel can. It contains rechargeable beads that do an excellent job of creating a healthy environment for your guns.

This is one of the most versatile units on our list, and it is even classified as a top-rated portable desiccant dehumidifier. You can use it in your gun safe or other areas of your home with excessive moisture. The compact design and canister shape allows you to fix the unit even in tight spaces.

Unlike dehumidifier rods, this unit does not need electricity or batteries to get rid of humidity in the air. Once its beads absorb plenty of moisture and reach their capacity, they change color. At first, they will adopt a yellowish hue, and then they will turn dark green when they need to be recharged.

The recharging process is easy-peasy. Place your device in an oven for a few hours, and it will be ready for reuse. I also like the fact that the can is silver in color. It looks way nicer than a good number of similar products in the market.

You can choose from a range of unit sizes to find a silica gel can that suits your needs. Depending on the size you choose, and also the moisture levels in your safe, the beads can last for 1-6 months before they need recharging. This offers you a stress-free means of keeping your safe’s contents free of damaging levels of humidity.


  • Simple and compact design can easily fit in tight spaces
  • The silver color blends well in just about any area
  • Renewing the silica beads is easy-peasy
  • Available in a range of sizes


  • You may need to recharge the silica beads more frequently if you experience high humidity levels

2. LOCKDOWN GoldenRod Original: Best Safe Dehumidifier Rod

In case you need an efficient means of preventing moisture from damaging the contents of your safe, there are good reasons to consider using a dehumidifier rod.

One of the best models to invest in is the LOCKDOWN GoldenRod. Instead of absorbing excess moisture from the air, this model heats the air to regulate humidity levels automatically.

Its method of getting rid of excessive moisture is quite effective, and this gives it an outstanding coverage area. Better still, this unit is available in 4 different sizes, and while the 12-inch rod offers a coverage area of 100 cubic feet, the larger 36-inch rod can provide 500 cubic feet of protection.

Something else that makes this model highly effective is that it features a glass tubing that transfers heat to the air.

The construction of the rod is on another level because the glass tubing is insulated in Vermiculite, which is a naturally occurring mineral. This ensures proper distribution of air to arrest any risk of rust-buildup or mold growth.

When plugged in power (110V-120V AC), this rod can heat up to a maximum of 150 degrees Fahrenheit. Even though you cannot hold it with your bare hands, the heat is still too low to start a fire. Lockdown also includes mounting brackets in the package to enhance user safety.

This device is as close to perfect as it can get, and it even comes with a long 6-foot cord. It is easy to use, has a reasonable coverage area and can last for years on end with minimal maintenance. What’s more, is that it features a pocket-friendly price tag and is backed with an impressive warranty.


  • Highly efficient and easy to operate
  • Sturdy and well-constructed rod
  • Reasonable coverage area
  • Available in multiple sizes
  • Uses standard US household current — 110V-120V AC
  • Floor mounting brackets included


  • This is an electric model that requires a constant power source

3. Eva Dry Mini: Best Cordless Gun Safe Dehumidifier

Let’s be honest; if you care for the environment, you are likely to stick to home remedies like using baking soda with the hopes of reducing your carbon footprint.

Fortunately, models like the Eva Dry wireless dehumidifier are environmentally friendly, and they allow you to take a break from ancient means of lowering humidity.

This model uses renewable silica gel beads. These beads trap airborne moisture for about eight weeks before they need recharging. We must also mention that recharging the beads is as easy as plugging in the unit in a well-ventilated area.

Don’t get me wrong, simply because this device has a plug-in recharging mechanism does not mean it has to be plugged into a power source to keep your safe dry. It uses neither batteries nor electricity, and this ensures entirely noise-free operations.

Thanks to the compact design, you can fit the device in tight spaces, perhaps areas where other dehumidifiers cannot fit. Even though it does not have a state of the art indicator system, you will know that the beads need recharging once they change color from blue to pink.

This unit is no bigger than a car radio, although it has an impressive absorption capacity. It can remove 4-6 ounces of moisture from the air and covers areas up to 333 cubic feet. The recommended frequency for recharging the silica beads is within 2-4 weeks, depending on the humidity levels in your safe.


  • Environmentally friendly, yet effective
  • Compact design (can fit into tight spaces with ease)
  • 333 cubic feet coverage area
  • Up to 6oz absorbing capacity
  • Highly durable (silica beads last for over 10 years)
  • Easy recharging process


  • Mainly ideal for mild moisture conditions in small spaces

4. PEET Dryer: Best Electric Gun Safe Dehumidifier

If you are not new to experiencing humidity problems, there is a good chance you have heard about PEET dryers. This is a leading dehumidifier manufacturer, renowned for some of the most effective, yet reasonably priced products. PEET safekeeping dryer and dehumidifier is one of the best gun safe dehumidification systems on our list.

This is an electric dehumidifier that works best when placed at the top corner of a safe. Before we dive in any further, this unit is not for you if you have a small or rather cramped up safe. If your safe is big and roomy, however, keep on reading.

Among the first things, you may notice is the unique design of the device. Instead of sitting horizontally, it sits vertically and features a base and tower for proper air circulation. This patented design also ensures all surfaces of your budget gun safe are covered.

Once the machine is plugged into power (any 110-120 volt US household current), it pushes out heat through its top rod and covers 80 cubic feet approximately. There is no in-built fan, so the operations are relatively quiet, and you will also not see any noticeable airflow.

It’s hard to deny that this is a well-constructed and visually appealing device. However, it also has some downsides that are worth noting before purchase.

First, it has no indicator system of any sort, although this is not necessary, especially because it is not a desiccant unit. We also noted that the cords and plugs included in the package are not of the best quality.


  • Designed to ensure excellent distribution of heat
  • Fancy design, ideal for roomy safes
  • Up to 80 cubic feet coverage area
  • Easy to install
  • Silent operation
  • Solid value for the price


  • Available in only one size option
  • The power cord and plug feel cheap

5. LOCKDOWN Dehumidifier Rod Black

If you like the efficiency and convenience of using bar-type dehumidifiers, here is the perfect model for you. It is an electric model engineered to work by increasing the temperatures in your safe slightly. The unit radiates heat all through the vault’s interiors to effectively kick out unwanted moisture.

You can mount the rod at any low point in your safe.  With the package, you will receive a quick plug attachment and a mounting bracket that make the installation process easy and quick. Unfortunately, you need to drill your safe if it lacks an in-built power hook-up.

What makes this rod better than other models in the market is that it constantly heats the air in the safe to about five degrees higher than the air outside.

It is capable of reaching 120 degrees Fahrenheit, and this not only lowers the humidity but also prevents possible damage caused by condensed air in the safe’s interiors.

In terms of coverage, the unit can offer protection for a 100 cubic feet range approximately. This is effective enough to remove moisture from vaults that are big enough to hold about 18-36 guns. Better still, you can choose from a range of unit sizes to ensure your unique needs are met.

Because this is a dehumidifier rod, it can get overly hot, and this is expected. What came as an unpleasant surprise is a cheap-looking plug that is clearly not up to the mark. For the price, however, this device offers solid value.


  • Easy to install and use
  • Compact enough to fit in tight safes
  • Different sizes are available (12-18 inches)
  • Up to 100 cubic feet coverage area
  • Cheaper than other alternatives


  • Compared to other parts of the unit, the plug looks out rightly cheap

6. Barska Safe Moisture Absorber Dehumidifier

Next on our list is a model that ranks as the best dehumidifier for gun safe. This device is a cut above the competition because it comes with a convenient wet and dry indicator window — a feature you will not find in a good number of models.

Whether you want to dehumidify your gun safe, car, or closets, this is a unit we highly recommend.

Another outstanding perk is that it uses specialized moisture meter beads. They help to eliminate mold issues by absorbing excess moisture from the air. Once the device reaches its moisture absorption capacity, the meter beads turn green, meaning the unit is ready to be recharged.

Recharging the dehumidifier is a piece of cake. Just plug it into a standard wall outlet for a few hours until the meter beads on the wet/dry indicator window turn orange.

In case you have valuable stuff in a small safe, you don’t need to worry because this is a compact size dehumidifier. It measures 6 by 3 inches and can fit into tight spaces without a problem. You can even place it inside moisture-prone drawers in your kitchen or even under the sink.

This is a rechargeable dehumidifier, so you don’t have to go through the hassle of changing its beads. It offers the perfect lasting solution for preventing long-term moisture damage.

The coverage area is quite impressive for such a small device, although you may need to install several units if you have a big, roomy safe.


  • Dry/wet indicator window
  • Compact size and can fit into tight spaces
  • Easy to recharge by plugging into any standard household outlet
  • Durable and can last for about 3 years
  • Quiet operations
  • Versatile and ideal for use in storage drawers, closets, and rifle safes


  • You need to buy several units to dehumidify larger safes effectively

7. Browning Ever Dry Electric Rod

If you are looking for the best dehumidifier for gun safe in the garage, the Browning Every Dry rod may be just what you need. This is an eighteen-inch unit that can be used on safes that are 13-inches or larger. What makes it a real masterpiece is the fact that the cord is removable for easy installation.

Earlier in our review, we analyzed the LOCKDOWN GoldenRod. Well, the performance of this model is quite comparable to that of the GoldenRod. The only difference is that this unit is cheaper, and it comes from a lesser-known brand.

Another perk that gives it an edge above other electric rods is that it does not get overly hot. The heat produced is adequate to get rid of moisture problems, although the unit is well insulated to ensure you don’t suffer from burns in case you touch it. This makes it safe for use, even in homes with kids and pets.

Something that may pose as a turn off to some people is that the electric rod is only available in one size. It is, however, efficient enough to provide a coverage area of 200 cubic feet.

In case you have a larger safe, this means you need to invest in more than one dehumidifier for you to protect your valuables effectively.

During our tests, we used a digital hygrometer to keep an eye on the humidity levels and temperature of our safe after installing the Browning Ever Dry Rod.

Unlike a good number of units that either do a shoddy job eliminating moisture or leave the air overly dry, this device kept the humidity levels at 50%. This gives it a definite plus point over other rods in its class.


  • Removable cord for easy installation
  • Well-constructed and efficient
  • Well insulated for enhanced safety
  • 200 cubic feet coverage area
  • Outstanding performance


  • Available in only one size

8. Dry-Packs 750 Gram Silica Gel Canister Dehumidifier

Let’s start by giving this model thumbs up for its design. Its construction is different from that of most dehumidifiers, and this is what makes it uniquely appealing. What’s more is that it has a large volume of 750g, meaning it offers a bigger moisture absorption capacity.

The design of the unit ensures it can fit with ease, even in smaller safes. Then again, the canister has sturdy aluminum construction for maximum longevity. Just reactivate the silica beads once they are full of moisture, and you are good to go.

So how do you know that the beads need reactivating?

It’s simple. Check the indicator system on its lid and note when it turns from orange to dark green. To reactivate the silica beads, place the canister in an oven for a few hours.

Using this unit in your gun safe helps to keep your firearms free from rust and mold. You can also place the canister in various other enclosed spaces to arrest the risk of damage caused by moisture issues. This could be in areas like your storage bins, craft supplies drawers, and toolboxes, just to mention a few.

It’s hard to point out any significant flaws. Even though this model works effectively, it is still not as reliable as an electric device. Just like when using any kind of desiccant dehumidifier, you must continuously keep an eye on the canister to find out when it needs reactivation.


  • Huge 750gm dehumidifier
  • Sturdy aluminum construction
  • A convenient visual indicator system
  • Versatile and can be used to dehumidify any area with moisture issues
  • No electricity or batteries needed
  • Easy to reactivate
  • Designed to last for years


  • It requires regular reactivating

Gun Vault Dehumidifier Buying Guide

Before purchasing a firearm safe dehumidifier, there are several important aspects you must consider. Here are the most vital elements to keep in mind.

Absorption Capacity

Gun safe dehumidifiers can differ like day and night when it comes to their absorption capacities. A good number of models depend on silica gel beads to trap moisture. In this case, the quantity of the silica gel beads will determine the amount of water the dehumidifier can absorb.

If you choose silica gel dehumidifiers instead of their electric counterparts, make sure you get the largest model possible.

Size and Coverage Area

It’s a no brainer that for a dehumidifier to work for you, it needs to fit in your gun safe. That said, take the dimensions of your safe and check a product’s description to understand its overall size.

Most importantly, get to know about the cubic feet the dehumidifier can cover. It’s as simple as ensuring your product of choice is a perfect fit for your safe.

Power Cord Length

If you opt to buy an electric dehumidifier, you must take into consideration the length of its cord. Typically, you need to run the power cord through a hole in the safe and plug it into an outlet. If the cable happens to be too short, you may struggle to do this.

Corded or Cordless

The construction of your safe will play a leading role in dictating the dehumidifier model you can choose. If you settle for one with a cable, ensure you can access an electric outlet with ease.

Some safes have electrical provisions in place, while others need to be drilled to allow the power cables to pass. In case you are not ready to bore holes into your safe, then perhaps you may want to consider choosing a cordless dehumidifier. No installs are necessary —just place the unit in the safe, and you’re done!


Desiccant dehumidifiers can work effectively for years as long as they are properly maintained. Once they soak up too much moisture, they stop working and need to be reactivated or recharged.

The recharging process may differ from one model to another. Some need to be plugged in for reactivation, and other models need heating in an oven. You should also beware of units that cannot be reactivated.

Indicator System

Models with an indicator system keep you in the know when your unit needs to be reactivated or recharged. The majority of rechargeable desiccant dehumidifiers, if not all of them have some sort of window that lets you know when recharging is needed.

From our research, we gathered that the indicator system are not created equal. Some are easy to read while others require you to depend highly on guesswork, and perhaps recharge the beads after every two weeks.

Types of Gun Safe Dehumidifier

When choosing dehumidifiers for gun safes, you have two main options — desiccant and electric. Let’s break them down in detail to help you identify the option that best suits you.

Desiccant Dehumidifiers

Desiccant dehumidifiers use silica beads to absorb excessive humidity from the air. They come in an array of shapes and sizes, although all models have silica gel packets of different quantities. The quantity of these beads dictates how often you have to recharge or reactivate your unit.

Recharging a desiccant dehumidifier is not rocket science. You simply need to use heat and vaporize the absorbed moisture. Some models can be plugged in to release the moisture, and others need to be placed in an oven to recharge.

What makes desiccant units a top choice for most people is the fact that they are easy to set up and install. These dehumidifiers are durable and cheaper than their electric counterparts, yet they require neither batteries nor electricity. Just place the unit in your gun safe and promptly recharge the beads.

Electric Dehumidifiers

Electric dehumidifiers offer premium solutions, especially for people who live in areas that experience excessively humid climates. These units are more efficient and powerful because they use an exposed heating element to kick out moisture from your gun safe.

The installation process can, however, get a little complicated, especially if your gun safe lacks ready electrical provisions. In this case, one is forced to go through the hassle of drilling power cord holes in the safe.

Before you decide to just settle for a desiccant dehumidifier, you must understand that it may not be as powerful as a corded unit.

Benefits of Using Gun Safe Dehumidification

Dehumidifiers are invaluable assets. However, we can’t disregard the fact that there are more than a few brilliant home remedies that can help you lower the humidity in your gun safe. For instance, you can use charcoal or baking powder.

So, why invest in a gun safe dehumidifier?

Get Long Term Solutions

Using an electric or desiccant humidifier will offer a lasting means for keeping the humidity in your gun safe regulated. The solutions provided in this case are reliable, and they cannot be compared with the results of basic home remedies.

Little Effort Involved

Even home remedies that work require you to do some serious heavy lifting to keep your gun safe free of moisture. For instance, placing coffee grounds in an open bowl in the safe can help absorb excessive humidity.

However, you need to replace the bowl frequently, and this can be both expensive and time-consuming.

Electric dehumidifiers work flawlessly as long as you have a stable power supply. On the other hand, desiccant units only need to be recharged once a month or so. This all depends on the humidity levels in your area. These units provide better results and need little or no maintenance.

Inexpensive and Durable

Dehumidifiers only require you to make a one-time investment and get a trouble-free service for years. In fact, desiccant units don’t need power from electricity or batteries, so they are cheaper to maintain in the long haul.

Highly Portable

Safe dehumidifiers are pretty small and lightweight. You can always pick them up and use them to dehumidify other areas in your home.

Damages Done by High Humidity to Gun Safe

If you have not experienced first-hand how humidity can damage your gun safe, it is possible to wonder whether investing in a dehumidifier is necessary. Well, let me help you clear out your doubts by expounding on the damages caused by high levels of humidity.

Rust Build-Up on Your Safe and Guns

Any moisture infested area causes metals to corrode and rust. Rust on your guns can cause degradation that is detrimental to not only their cosmetic appeal but also their structural integrity.

Moreover, even a strong and sturdy safe can suffer irreparable damage if rust is allowed to build-up over time.

Ammunition Damage

Whether you buy new packs of ammunition from gun stores or you reload your bullets using a reloading press, the bottom line is that ammo is expensive. Storing your bullets in humid environments will not only cut short their shelf life but also hurt their performance.

Humidity is notorious for causing ammunition degradation. At first, you may notice that your ammo lacks accuracy. After this, it will not be long before the bullets fail to fire altogether.

Mold Infestation

Mold has a very distinct and nasty smell, not to mention that it can cause a myriad of health concerns. It thrives in humid areas, so it’s likely to grow on the safe’s internal foam coating that protects your guns from scratches.

It is of paramount importance for you to invest in a dehumidifier the instant you invest in a gun safe. After all, mold remediation projects are not cheap, and in most cases, the professionals have to remove the mold-infested materials entirely.

If you want to effectively arrest the risk of a mold infestation, ensure your safe is installed in a dry and well-ventilated area.

Useful Accessories

One of the biggest enemies of your stored valuables and guns is excessive humidity. That is why you cannot afford to underestimate the importance of investing in a top-quality dehumidifier.

Let’s have a look at other useful accessories that can enhance the appearance and functionality of your gun safe.

Gun Safe Lights

Gun safe lighting kits are understated pieces of equipment. In case your unit lacks lights or has poor lighting, you have the option of installing electric or battery-powered lighting kits

Magazine Holders

To better organize your collection of ammunition, you need magazine holders. Ammo magazines ensure you are ready to defend yourself the instant a situation arises. For the best experience, find models that have screws for mounting or can be attached to magnet mounts.

Gun Safe Door Panel Organizer

Door panel organizers are incredibly useful accessories. They help to maximize the space inside your gun cabinet or vault. Some of the best models are highly customizable, providing lots of pockets for storing and organizing your valuables.

Gun Hangers

If you own a collection of revolvers, using a pistol rack will ensure you can store more guns in less space. On the other hand, rifle rods are instrumental in increasing the capacity of a gun safe by nearly 50%.

Pistol racks in specific can help you avoid space wastage. Some models can hold guns over and underneath a shelf, and some variants only hang under shelves. It is also possible to find pistol racks ideal for concealing your weapon under bed frames.

Indoor Temperature and Humidity Monitor

For gun safes, you should keep the humidity under 60% and the temperature at around 70°F. This will ensure that your ammo, guns, and valuables remain in top condition.

A dehumidifier can help raise the temperature in your gun safe and also control the humidity. However, you will need a hygrometer to keep an eye on the conditions in your vault.

Frequently Asked Questions

  1. How frequently should you replace a safe dehumidifier?

Not so frequently. A decent number of models, including the ones on our list, work flawlessly for a good number of years. It is, however, crucial to get your desiccant unit replaced if it is unable to absorb the moisture, even when recharged.

  1. Where do you put a dehumidifier in a gun safe?

If you choose to install an electric dehumidifier, you need to place it at the bottom of the safe. This is because the heat produced will rise, and you want all areas to be heated evenly.

Placing the dehumidifier at the bottom of the safe also allows better circulation of air. This ensures that moisture does not condense on the guns or the internal walls of the safe.

  1. How does a desiccant dehumidifier work?

Desiccant units use products like silica gel beads to regulate humidity. These beads absorb excessive moisture and can remain active for about a month. You will, however, need to recharge or reactivate them as advised by the dehumidifier manufacturer.

  1. My gun safe has a seal; do I still need a dehumidifier?

Gun safes with seals can prevent water, fire, and smoke from damaging their contents. However, it is not guaranteed that they can lock out excessive humidity, especially when placed in moisture-prone areas such as the basement. To be on the safe side, you still need to install a dehumidifier.

Final Words

We hope the information we have offered will make it easy for you to find the best gun safe dehumidifier. Our list contains different types of units, ideal for different gun safe sizes. We aimed to ensure you can find a top-quality product that matches your unique requirements.

In case you have a big collection of guns, hence a bigger safe, we recommend investing in multiple small or medium size dehumidifiers. You could also settle for a rod-type unit, as long as it has a decent coverage range.
