Best Dehumidifier for Gun Safe in Garages: A Review

1. Eva Dry Wireless Mini Dehumidifier

Excellent at absorbing moisture in small spaces, this portable and chargeable dehumidifier by Eva Dry is perfect for the smaller gun storage locations.

A one-car garage, bedroom, closet, or car trunk used as firearm storage would benefit from its humidity-removing and mold-growth-preventing capabilities. 

Product Highlights

Aside from having its absorption capacity of six ounces, this tiny machine also packs a lot of power, lasting up to 30 days before it needs recharging.

It also requires no cables or cords, making it super convenient for gun owners to use.

Top this all off with the machine’s excellent portability, and there’s likely no way you won’t be picking this one up on your way home.

You would love this odor-free and super-dry dehumidifier that has an industry-leading five-year warranty.

That means you can eliminate moisture without having to trouble yourself with leaks or molds.

As far as usage is concerned, the Eva Dry Wireless Mini Dehumidifier makes it easy for you.

No need to worry about spills or messes like you may have with a different model.

This one simply requires you to hang it, and then go.

You will also adore it design-wise. It won’t just fight garage humidity, but also the humidity in your boats, cabinets, gym bags, and gun safes up to a volume of 300 cubic feet.

The Good

The Eva Dry Wireless Mini Dehumidifier’s size, portability, and power make it super convenient and safe for its users.

It also means you can transfer the device from one place to another without worrying if it’s too troublesome to move, has too many cords or cables, or needs recharging.

The Bad

As awesome as this mini dehumidifier by Eva Dry is, it can get a bit too warm when plugged in for too long.

In fact, if it’s plugged in for 24 hours during a particularly hot day, there is a good chance that parts of it will melt.


  • Portable and rechargeable
  • Doesn’t come with cords and batteries
  • Can last up to 30 days when fully charged
  • Super easy to use


  • May melt when plugged in for too long

2. Pro Breeze Electric Mini Dehumidifier

Here’s another dehumidifier that’s on the small side.

It can give the best models out there a run for their money in combating humidity in almost any room.

Given, of course, that the room doesn’t exceed 150 square feet in area size.

Product Highlights

Humidity is a problem that can happen in any room, not just in your garage where you keep your firearms.

Lucky for you, the Pro Breeze Electric Mini Dehumidifier can work just as well in your kitchen, bathroom, caravan, and walk-in closet.

You would think that removing nine ounces of moisture from a 150-square-feet area would be too much for this tiny thing, but that’s not the case at all.

The Pro Breeze Electric Mini Dehumidifier can perform the task effortlessly until its 16-ounce tank is full.

When that happens, this electric mini dehumidifier will shut off automatically and turn on its LED light to signal that the tank needs draining.

Using this machine, you would think it was broken because it’s ultra silent.

Its operations are whisper-like, which is something you’ll find really convenient for bedroom or office use.

No noise means you can sleep and work without interruptions.

The Good

As far as dehumidifiers go, silence is a good thing. The more silent your machine is, the better.

With the Pro Breeze Electric Mini Dehumidifier, sounds barely go over whisper level.

That is awesome, given that it operates quite efficiently in lowering the humidity in rooms up to 1200 cubic feet in volume.

The Bad

Since the device itself is pretty small, its reservoir doesn’t take too long to fill up.

If you don’t want to empty the tank constantly, you can do something for it to empty out into a larger container.


  • Silent operation
  • Great size; takes up very little space
  • Extremely effective at lowering the humidity in small rooms


  • The reservoir can fill up quickly

3. SEAVON Electric Upgraded Dehumidifier

If you’re storing your gun safe in a larger garage or room, you would want to pick up this electric dehumidifier from SEAVON.

Capable of absorbing moisture in rooms as large as 195 square feet, this machine ensures that high-humidity levels, leaks, and molds cease to become a problem in your home.

Product Highlights

While great for large rooms, this upgraded dehumidifier is also efficient in clearing out moisture from small rooms.

It’s on the smaller side, too, so you won’t have a problem moving it from one room to another as you see fit.

The automatic shut-off function of the SEAVON Electric Upgraded Dehumidifier is another plus when it comes to this dehumidifier.

It helps ensure that the device’s reservoir is drained right away, and you can keep on using it.

Then, we have another aspect that’s worthy of praise: super-silent operations.

With this function, you don’t have to worry about sounds from your dehumidifier waking you up at night.

Lastly, because this machine is tiny, it can save you a lot of space.

You will barely know it’s there due to its size and whisper-like sounds.

To top it all off, this SEAVON model is also energy-efficient, which means it’s barely going to factor in your electric bill.

The Good

The SEAVON Electric Upgraded Dehumidifier packs quite a punch for its size. Plus, it’s not a noisy, brutally-delivered punch, either.

It’s a perfectly-placed, efficient punch that covers all your needs when it comes to lowering the humidity levels of your garage and other rooms in your home.

The Bad

This mini dehumidifier is pretty good overall. The only downside to it is probably the slightly flawed design.

You’ll notice that after emptying the tank of water, it will be a little bit difficult to clean.


  • Small but powerful
  • Especially great for bathrooms
  • Compact and lightweight
  • Energy-efficient


  • Quite difficult to clean the tank

4. Gocheer Upgraded Dehumidifier

High humidity in large rooms doesn’t stand a chance against this upgraded dehumidifier by Gocheer.

Whether you have a sizable basement, garage, bathroom, or kitchen, this machine can lower the moisture in the area quietly and efficiently.

Product Highlights

Capable of dehumidifying a room as big as 320 square feet, this Gocheer model has a lot going for it.

Part of what makes it highly effective is its 2000ml tank capacity and upgraded energy-saving function. 

These two features are responsible for handling moisture, leaks, and molds, day-in and day-out, without putting a dent on your electric bill.

Two of our most favorite qualities in dehumidifiers are the auto shut-off system and its ultra-quiet performance.

So, with this one, you also get to experience the full potential of a high-quality dehumidifier without any noise pollution.

Consider the Gocheer Upgraded Dehumidifier as one of your top options if you’re also looking for a dehumidifier for your bedroom or bathroom.

The Good

This dehumidifier’s reservoir takes more than a week to fill up even when you place it in a fairly large room.

Combine this with its energy-efficiency and ultra-silent operations, then you’ve got a machine made for ultra convenience.

The Bad

The only downside to this Gocheer dehumidifier is its power converter.

Sometimes this part of the device can run really hot to the point that it burns your skin.

Luckily, you can find a way around this by running the machine on just 12 to 13.5 volts.

Then again, the fact that an experiment had to be conducted to find a solution around something this dangerous was a major inconvenience.


  • Super energy-efficient
  • Ultra silent
  • Dehumidifies large areas
  • Has a large-capacity tank


  • The power converter can get too hot to touch at times

5. Waykar 40 Pint Dehumidifier

As the only full-size product on our list, the 40-pint dehumidifier by Waykar is not as portable as the others.

It isn’t any less impressive because it addresses high-humidity levels in very wide spaces.

Product Highlights

Capable of working on spaces up to 2000 square feet, there isn’t any room that this device can’t clear moisture.

It can adjust humidity levels from 30 to 85 percent and maintain an ideal humidity ranging from 45 to 55 percent.

Add this to the fact that its reservoir capacity can reach up to five gallons, and you basically have a high-quality, all-around dehumidifier.

As a full-size dehumidifier with an intelligently-running system, the Waykar 40-pint is perfect for the modern home.

It shuts off automatically when the tank is full and powers on when the bucket is empty.

In the event of a power outage, the machine will also restart instantly.

As the largest dehumidifier on our list, the Waykar 40 Pint Dehumidifier also happens to be one of the easiest to use.

Not to mention, it’s self-draining, and you may decide to attach it to a drainpipe so that you don’t have to drain the reservoir constantly.

Of course, should you decide not to do this, you can rely on the “full tank” indicator to tell you that you need to drain the bucket.

The Good

The size and power of the Waykar 40 Pint Dehumidifier are its strongest points.

Thanks to these two aspects, the Waykar 40-pint dehumidifier can meet an entire range of user needs when it comes to moisture control.

The Bad

Coincidentally, it’s also in the size where the device’s weakness lies.

Compared to the other dehumidifiers in our compilation, the Waykar 40 Pint Dehumidifier is not as portable.

While you won’t have a hard time rolling it from one room to another, bringing it to your car or traveling with it is another story.


  • High-capacity tank
  • An intelligent system with automatic humidity control and shut-off
  • Extremely easy to use


  • Not as portable as mini humidifiers

Buyer’s Guide

So, let’s take a moment to discuss what qualities to look for in dehumidifiers, particularly when they’re used for safes and cabinets.

Keep in mind that it’s different from when selecting dehumidification technology for rooms or buildings.

1. Absorption Capacity

You would want to consider absorption capacity when it comes to these types of dehumidifiers.

It is a huge factor, especially when you live in extra humid regions.

However, when it comes to capacity, you don’t just want to look at the volume a product can hold, but how much its reservoir can handle before needing to be emptied.

2. Size

Size, and, while we’re at it, coverage, are some of the main concerns when it comes to selecting dehumidifiers for small enclosures.

You need to make sure that your chosen product is compact enough to fit into the safe properly.

It has to leave more than enough space for your guns and ammunition.

3. Installation Process

In this case, we’re talking about how easy the device is to install.

For the most part, this likely won’t be something with too many cords or cables.

Still, these models are typically the most efficient at delivering dehumidification technology.

If a wiring run isn’t present in your safe, you’ll need to make some major modifications to get power inside.

If such is the case for you, then a wireless dehumidifier would probably be the wiser choice.

4. Types of Guns You Own

Yes, some gun safe dehumidifiers are better for some weapons than others.

Guns made of wood, for instance, require more precision in terms of humidity control.

That is because too much or too little humidity may not be ideal for the gun.

Then, we have guns made of plastics, metals, composites, which can get away with being in a too-dry environment.

In this case, the lack of humidity precision won’t be an issue.

Lastly, take a look at your ammunition.

Those made of metal casings can handle moisture intrusion better than those made of plastic.


1. Is it okay to put gun safe in garage?

As far as gun safes are concerned, you should place them where there’s a low risk of a fire, and in an area with just the right humidity.

You should also consider the risk of theft. In case someone can easily see the inside of your garage from the street once the door is open, avoid installing your gun safe there.

If there isn’t any other option but to place your gun safe in your garage, though, you’ll want to make sure it’s bolted securely to the garage floor.

Also, make it a point to position your safe in the most inconspicuous area possible.

Then, don’t forget to use a dehumidifier to combat moisture in your safe at all times.

2. Will guns rust in a safe?

No other storage option is more ideal for guns than a gun safe.

It is a unit that keeps your guns safe, but also makes them easily accessible when needed.

Gun safes can be accessed either by code, key, or fingerprint.

Still, as awesome as gun safes are, they don’t necessarily guarantee protection from rust.

If you install your safe in a room that has high humidity, for instance, moisture can slip into the cracks and crevices of your safe and slowly ruin your guns and ammunition.

Of course, you can combat rust, dust, and corrosion using gun storage bags and dehumidifiers.

3. Is a dehumidifier good for a garage?

If you live in a humid area, condensation gathering in your garage floor is probably normal.

Still, you can’t take this lightly because it can impact the room’s structural integrity due to wood rot and mold.

The best way to deal with garage humidity is by using a dehumidifier that’s best suited for such an environment.

It makes you aware of the moisture levels and reduces the moisture mold spores need to survive and thrive.

Not to mention, it also prevents metal tools from rusting and wood from rotting.

4. What size dehumidifier do I need for my gun safe?

Before we get to answering this question, let’s first take a look at the types of dehumidifiers saturating the market.

There are two, the desiccant and electric models.

When it comes to efficacy, the electric dehumidifier holds the edge over the desiccant.

That said, it usually takes a lot more work to install, requiring you to drill a hole in the wall where you’ll place the safe and connect the wires.

If you think all this is too much trouble, then you’re better off with a desiccant dehumidifier.

Gun safe size should determine dehumidifier size. The larger the area, the more power is required from a dehumidifier to perform its intended function.

For instance, if you have a gun safe that’s eight feet high, four feet long, and six feet wide, it’ll have a total volume of 192 cubic feet.

That means you would need an 18-inch dehumidifier rod for your gun safe.

If you’re using a dessicant humidifier, though, it becomes less about the size and more about the device’s absorption capacity.

Naturally, bigger gun safes will need desiccant humidifiers with higher capacities.

With certain desiccant models, they can cover up to 33e cubic feet.

Still, performance-wise, it would be wise to go for the electric humidifier, which is capable of combating excessive amounts of molds and mildew inside the safe.

5. Is it safe to leave dehumidifier on all the time?

If you’re cautious about it, then leaving a dehumidifier unattended should be okay for the most part.

Of course, you’d want to invest in one with an automatic shut-off feature so that it’s safe to leave in specific scenarios.

In this case, you can leave the appliance running all the time and just get back to it when you need to empty the tank.

Still, you’re going to feel more at peace with a unit that can drain continuously.

Also, keep in mind that keeping your dehumidifier on an entire day may result in a higher energy bill.

Before you attempt to do this on your appliance, make sure you’re well aware of its descriptions and always consider safety first.

Wrapping Up

If you’re a gun owner who’s particular about safe storage for your guns and ammunition, you’ll likely be concerned with proper care, as well.

While it’s true that the climate and environmental conditions in your area will influence how severe the humidity is, you can expect the best dehumidifier for gun safe in garages to have all the bases covered.

But first, which among our five top-performing appliances is it?

It seems appropriate that the only full-size dehumidifier from the group would end up standing out in all the best ways.

The Waykar 40 Pint Dehumidifier shines in all aspects necessary, except portability.

Then again, it isn’t really realistic to be carrying around or traveling with a gun safe, so most would probably not see this as a requirement.

In terms of absorption capacity, performance, energy efficiency, ease of use and installation, and humidity control, the Waykar 40 Pint outperforms the other four on our list by a considerable margin.

Still, there are different kinds of gun owners, and not all of them may own a wide arsenal of firearms and ammunition that need to be kept in a gun safe in a garage.

If you happen to be one of them, then any of the high-quality mini dehumidifiers may be an acceptable choice.

Besides, they do hold the edge in terms of affordability and portability, which could be essential requirements for you.
