1. LOCKDOWN GoldenRod Dehumidifier Rod

LOCKDOWN GoldenRod Dehumidifier Rod

I believe the best way to start off my list is with a name that almost all gun owners know and trust when it comes to gun safe moisture control, Lockdown. This brand has made a massive name for itself with tier Goldenrod Dehumidifiers. Sure, it is a bit pricy, but there are no better alternatives to this one.

If I had to use one word to describe this dehumidifier, I would use versatility. It comes in four different sizes ranging from 12 inches to 36 inches to accommodate different sizes of gun safes. The total coverage it offers ranges from 100 to 500 cubic feet.

Needless to say, whether you have a large gun safe or a small one makes little difference with the Goldenrod dehumidifier. It is extremely easy to use and quite effective at eliminating humidity from the confines of a safe by raising the temperature inside and circulating warm air continuously.

For easier placement, the unit comes with detachable legs. It also comes with a 6 feet power cord that you can run through the back of the safe and connect to a power source. If you can get overlook its price, it is one of the best electric gun safe dehumidifiers out there.

Eva-dry E-333 Renewable Dehumidifier

Not everyone has the budget nor the desire to invest in the most expensive dehumidifiers on the market. But does that mean you have to settle with an option that does not do the job well? Not necessarily. The Eva-Dry E-333 Renewable dehumidifier is a great option for you if you want efficiency at a small price.

The maximum absorption capacity of this dehumidifier is 6 ounces which are not bad considering its price. It is designed to absorb moisture within an area of up to 333 cubic feet. So even if you have a larger safe, you should be fine with using this unit to remove moisture from the area.

Since it is a desiccant style dehumidifier, it needs recharging after a few days depending on the amount of moisture it removes. In typical conditions, the unit requires recharging after around 20 to 30 days. Frankly, this is not bad at all, considering how affordable and efficient it is.

Recharging the dehumidifier is also quite easy. If you see the color of the crystal change to yellow, just toss it in the oven and heat it up for a while. It requires no electricity, and as the best cordless gun safe dehumidifier, this one is unbeatable for the price that it asks.

3. LOCKDOWN GunSaver Dehumidifier

LOCKDOWN GunSaver Dehumidifier

Even at the risk of sounding biased, I decided to go with another option by the brand Lockdown. If the Goldenrod felt a bit out of your price range, then the GunSaver Dehumidifier is a decent alternative. It is not as amazing as the Goldenrod, but as an electric dehumidifier for gun safe, it gets the job done.

It only comes in two sizes, 12 inches, and 18 inches. I would only recommend getting this for small or moderately sized gun safes. For larger gun safes, even the 18 inches model might have a hard time eliminating all the moisture from the area. However, for smaller safes, this is a great pickup.

What makes it even more appealing is its affordable price. Normally, you do not find electric dehumidifiers at this price range are stuck with rechargeable, non-electric models. However, for those with their heart set out on an electric dehumidifier, the price is extremely attractive.

You also get detachable legs with it to set it down easily inside the gun safe. The power cord feels decent and is long enough to loop out the back of the safe to the power cord. To protect your firearms and other valuables from humidity at an affordable price, this one is a solid investment.

  • Available in two sizes
  • Perfect for small to moderately sized gun safes

Hornady is another top name in the industry that prides itself in providing safety and security for your firearms. They offer many fantastic gun safes and to ensure the firearms you store inside remain moisture-free, they bring you this Reusable Canister Dehumidifier.

I will say this right away; It is one of the best non electric gun safe dehumidifier out there. At its core, it is a desiccant style dehumidifier that uses silica gel to absorb moisture at a certain spell. It can absorb up to 750 grams of moisture which is quite a lot for its price and design.

The effective area coverage, however, is a bit limited, giving you only 50 cubic feet of coverage. So if you wanted the best large gun safe dehumidifier, this might not be the best pickup. However, for small and moderate units, the performance it delivers is unbeatable.

In addition, recharging the dehumidifier takes only around 4 hours in an oven turned up to 300 degrees Fahrenheit. It is compact enough to fit in any gun safe comfortably. For people with a larger gun safe, they have a bigger model available, which can be worth a pickup. However, at that price, I would recommend going with the Goldenrod.

  • Requires no power
  • Easy recharging process

5. Lockdown Silica Gel with Rechargeable Beads

Say what you will about desiccant dehumidifiers; you have to admit that they are pretty efficient at removing moisture from a tight space. And they are also cheap, making them a fantastic investment for small gun safe owners. If you are one of them, then why not check out this desiccant dehumidifier by the brand Lockdown.

Don’t get me wrong; if you can go with electric dehumidifiers like the Goldenrod or GunSaver by them, it would give you a better absorption in a larger area. However, for a small gun safe, the 750 grams of moisture absorption capacity that this unit provides should be more than enough.

There are two other versions of this model available with an absorption capacity of 40 grams or 450 grams if you have an even smaller gun safe. You can also find one that includes a Hygrometer for easier monitoring of moisture levels. Regardless of the model you go with, the price is not too much.

You might remember Barska as the brand that often comes up with fantastic new gun safes on a budget. As it turns out, they also have a budget-friendly silica gel dehumidifier that gives you fantastic levels of moisture absorption. And the best part is that it is rechargeable.

At first glance, you might be a bit disappointed with how it looks. And to be honest, I was skeptical too at first. However, once you try it out, you will be surprised by how efficient it is at keeping humidity at bay. It is available as a single pack and a double pack.

With a capacity of around 7 ounces, this is not designed for large safes. Instead, you would get a better performance out of it if you use it inside a nightstand safe or basically any single or double handgun safe. As long as the area inside the safe is small, it does the job perfectly.

You can also recharge it within 4 minutes if you crank up the microwave to 600 degrees Fahrenheit. The color changes from blue to pink when it has absorbed enough moisture. So that would be your cue to take it out, put it in the microwave and recharge it.

It boasts a coverage area of around 333 cubic feet which is pretty great for the price it asks. This means you can put it inside a larger gun safe and forget about it. But in the meantime, it will keep working and actively fighting moisture inside the safe, protecting your belongings.

The 5 ounces of absorption capacity that the dehumidifier boast is also quite decent. In a typical environment, it can work flawlessly for up to 30 days without requiring a recharge. This, of course, can change depending on the moisture level of the environment.

Thankfully, the recharging steps are pretty simple, and it also does not take too long to get to full charge. There is an indicator in the device that changes color to let you know whether you need to recharge it. However, it can take up to 10 hours to recharge fully, which is a bit of a downer.

By now, I think I have covered a lot of the small dehumidifiers out there to give you some solid picks. So to wrap up my reviews, I would like to go with a bigger model that might cost a bit more but gives you continuous moisture control. This option by the brand PEET is one of the finest pickups to protect your firearms against humidity.

Needless to say, it is an electric dehumidifier. That much becomes apparent the moment you set your eyes on it. But unlike the traditional rod-style design of electric dehumidifiers, it comes complete with a vent and a heating tube to eliminate humidity even at a large gun safe.

It has a coverage area of 300 cubic feet which should be enough for most people. The only gripe I have with this unit is its somewhat bulky size. It does take up a fair bit of space inside the gun safe. So if you already have stored a lot of items inside your safe, this might not fit that well.

But if you have the space to accommodate it, it should work like a charm. Even if your gun safe is in a high-moisture area like a garage, its performance should not disappoint you. It comes with its own power cord that you can loop out through the mounting holes of your safe and connect to the wall socket.

Things To Consider When Buying the Best Gun Safe Dehumidifier

When choosing our products, we considered a number of factors ranging from its absorption capacity all the way to its price and other features.

Knowing about these elements can help you understand your specific requirements and make sure you end up with the best possible unit for your purpose.

In the following section of the article, we will give you an overview of the things you should look for when buying the best gun safe dehumidifier.

Types Of Dehumidifiers

Before you can commit to a dehumidifier, you need to understand the different types that you can find. Generally, there are two main types of units that you can buy, electric dehumidifiers or silica gel dehumidifiers.

  1. Electrical Gun Safe Dehumidifiers

The best thing about this type of dehumidifier is its efficient moisture control. However, it tends to get extremely hot. There is a potential for severe disaster if you place them too close to your ammunition. Furthermore, you need to keep it separated from flammable objects inside the safe.

  • Silica Gel Gun Safe Dehumidifiers

This type of unit is simple and straightforward but requires some maintenance. It typically has a lower absorption capacity and requires you to recharge frequently. But a silica gel dehumidifier is easy to install and extremely affordable, making it perfect as your first purchase.

As you can see, both variants come with their own distinct set of advantages and setbacks. If you want higher absorption capacity and lower maintenance, and electrical dehumidifier might be what you want. However, if you are on a budget, there is nothing wrong with a good silica gel dehumidifier.

Absorption Capacity

One of the most important factors in a dehumidifier is its absorption capacity. It refers to how much moisture it can absorb before you need to recharge it. Some models use silica gel beads while a few use crystals. You also have units that use steel rods to absorb the moisture.

Take a look at the total amount of moisture it can absorb before committing to buy it. If the capacity is too low, you will need to recharge it more frequently. Typically, if the unit uses silica gel beads, the larger the size, the higher the absorption. With other moisture absorption mechanisms, that may not be the case.

Size and Coverage

Size is also an important factor when buying the dehumidifier. It needs to fit inside your safe without taking up too much space. You can find the dimensions of the unit listed under product specifications to give you an idea of how much space it will consume.

However, size is not the only thing you need to worry about. Each unit has a maximum area of coverage. If the coverage area is too small, it will not be able to fully absorb the moisture from the safe. In that case, you need to use two units for a single safe, which is not really worth it.

Installation Difficulty

The installation process and difficulty can vary from one dehumidifier to another. For instance, installing a silica gel bead dehumidifier is extremely simple. Since it does not require any batteries or power connection, you can simply place it inside your safe after activating it, and it will do its job.

However, with electrical dehumidifiers, you need to drill a hole for the power cable. If your gun safe already has the mounting holes pre-drilled into it, the process becomes much easier. You can use the holes to run the cable inside the safe to connect the dehumidifier.

In case your unit does not come with mounting holes, you need to drill it yourself. You should consult the instruction manual before starting the installation as some safes might not handle the drilling process too well. The last thing you want is to compromise the security of your gun safe just to install a dehumidifier.

Ease of Use

When it comes to using dehumidifiers, it is pretty simple and straightforward. Make sure you read the operation manual thoroughly when you get your hands on the device. It should get rid of most of your confusion and questions regarding how to use it.

Whether you buy an electric dehumidifier or a silica gel unit, make sure that it is easy to use. Look at all the safety instructions and operating procedures to get an idea of how it works before setting it up. If it seems too complicated for you, you could have a better experience with a different unit.


Although there are many high-end expensive dehumidifiers available on the market, most units are quite affordable. Unless you are facing massive moisture-related issues, there is no reason to exceed your budget. In fact, almost all the products you saw on our list of reviews are in the affordable range.

So, it is important to have a clear and concise idea about how much you are willing to spend before you start browsing the market. If you do not have a budget in mind, you might end up going for a highly expensive unit that might feel like a waste after a few days.

Evaluate Your Guns

Most people, when buying a dehumidifier, make the mistake of not checking their arsenal before committing to a product. However, that is a big mistake as some weapons react to moisture at a more dramatic level. If you are using any antique firearms, an affordable dehumidifier might not be able to do the job.

In that case, you need to shell out a bit extra and invest in a higher-end model. Before buying a dehumidifier, it is worth checking how your weapons react to moisture in the air. If the effect is minimal, you would be fine with a normal dehumidifier in the affordable range.

Maintenance Requirements

If you want to buy a unit that gives you a hassle-free experience, you need a unit that requires minimal maintenance. However, those units do cost extra, but if you consider the upkeep cost, it might be worth it for you.

 But if you check your guns frequently, taking care of your dehumidifier is not that difficult. Ultimately, it all comes down to your preference
