Best Dehumidifier for Gun Safe in Garage Buying Guide

Not sure what the best dehumidifier for your gun safe in the garage?

Check out our handy buyer’s guide to find out what to look out for and make that decision easier for you! 

Type

There are two main types of dehumidifiers for gun safes: desiccant and electric.

For those beginners, or needing a refresh, let's look at what they do: 

Desiccant Dehumidifiers

A desiccant dehumidifier absorbs the excess moisture in the air by using beads. These are usually filled with silica gel packets. The gel absorbs a set amount of moisture (labeled on the product description) before recharging. 

The recharging process involves heat to vaporize the water that's been absorbed. Some will be plugged in to produce their heat, whereas other dehumidifiers can be popped in an oven to recharge. 

It should clearly say on the dehumidifier which process to follow. 

Desiccant dehumidifiers are easy to install without having to worry about a power source, you can put them in the safe and carry on with your day. Some may explicitly say to be put at the top of the safe for example, but this will be made clear to you on the instructions. 

As they don’t use any electricity, they are cheap to run and usually cheaper than an electric model too. 

They can be recharged for years before needing a replacement, generally, 10 years is considered good mileage on these types of dehumidifiers. 

Electric Dehumidifiers

Electric dehumidifiers have gained popularity in recent years, viewed as superior dehumidifiers by some. They use heat to evaporate the excess moisture in the room. This is done by an exposed heating element to dry the air, thus removing the excess moisture. 

The installation of these can be tricky as they need to be connected to your mains power. To do this, you often need to drill a hole in the gun safe to run power cords through. 

You can get a battery operated dehumidifier, but this will require more attention. Generally, these are only suitable for those regularly using their gun safes. 

When using an electric dehumidifier you will need to be mindful of the temperature of your gun safe. Most of these heated rods can get quite hot, which could make your guns and bullets to handle. 

When deciding which to opt for, consider how often you will be using your gun safe, as both electric and desiccant dehumidifiers will need to be checked on. Whichever you decide, you can find some great prices on either option, making them great for any budget. 

Area

Before you get your dehumidifier you’ll need to measure the area of your gun safe. 

Most dehumidifiers work with cubic feet, you’ll need to work the measurements out with that. It is done easily by multiplying the length, by width, by height, which will provide you with the area in cubic feet. 

The bigger your gun safe is the more absorption capacity your gun safe will need. 

Absorption Capacity 

The absorption capacity of the dehumidifier is an important factor to make sure it's going to take enough moisture out of your air. 

This is normally given in oz of water and will be detailed on the product description, so be sure to check this carefully. 

Those opting for an electric dehumidifier won’t need to worry about this, as they generally operate with heat instead of absorption packets. 

How it Performs 

In terms of performance and longevity, an electric dehumidifier is a better option than the desiccant based ones. 

Although it will require being connected to power, an electric dehumidifier will last longer and be more effective at removing moisture and condensation in the safe. 

The choice is ultimately yours, but those looking for better performance should strongly consider an electric dehumidifier for their gun safe. 

Coverage 

Making sure the dehumidifier is going to cover the area of your gun safe is another important factor. 

Similar to the absorption level this should be located on the product description. The length of the rod (usually on electric dehumidifiers) will correlate to how much area the dehumidifier will be able to draw excess moisture from. 

Below is a table showing the conversion. Remember this is a rough guide and to check on the product description before purchasing to make sure it’s suitable. 

Dehumidifier Rod Length
Coverage area in cubic feet (approx.)
12 inches
100
18 inches 
200
24 inches
300
36 inches 
500

Size 

Once you have measured the size of your gun safe, found the absorption capacity out, and the coverage, the size of the dehumidifier itself is another factor to consider. 

You can find some nifty ones to fit smaller spaces, or fuller safes without taking up too much space. 

Ones that can be attached to the walls are great for those who want to preserve floor space, especially desiccant dehumidifiers which can be placed virtually anywhere. 

Safe and Easy?

Compared to an electric dehumidifier, a desiccant based dehumidifier is safer and easy to use. It removes the need to drill into your safe to connect your dehumidifier to power, or any batteries, you can simply hang it in the safe. 

Most dehumidifiers will come with a warranty now, giving you peace of mind while you use it. Be sure to check how long the warranty is when you purchase, and keep that proof of purchase safe, just in case you ever need to use it! 

Frequently Asked Questions

Some last-minute questions you need answering?

Stick around and check our FAQ’s out! 

How does a gun safe dehumidifier work?

Gun safe dehumidifiers are made to remove moisture, mold, mildew, and condensation from the safe. 

There are two types used: electrical and desiccant based, that we looked at in our buyers guide earlier. Be sure to check that out to help you figure out which is the best fit for you! 

Generally speaking, a desiccant dehumidifier uses silica gel beads to absorb the moisture from the air and will need recharging once full. 

An electric dehumidifier uses heat to evaporate the excess moisture in the air but will require batteries or a constant source of mains power to do this. You can find either option for an affordable price by checking out our earlier recommendations. 

Consider which the best fit will be for you and your gun safe before investing. 

Can I put my gun safe in the garage?

Providing there is enough security, then yes using your garage for your gun safe is perfectly fine. Ensuring the safety and security of your garage is key here, as well as the lower humidity level of the garage. 

If your garage is visible from the outside, you run the risk of a burglar trying their luck. To ensure safety, consider bolting the gun safe to the concrete floor. You can also invest in an alarm system. 

The gun safe in your garage will provide you with easy access and makes it easy to install. They are also kept far away usually from the kitchen and any fire damage is greatly reduced. 

However, there is often excess humidity in the garage (which is why we are here looking at dehumidifiers) and the risk of it being stolen, especially if the garage is visible to others. 

Providing that you take these security measures and invest in a dehumidifier, you can keep your gun safe in the garage relatively trouble-free. 

Can a gun safe be too dry?

While we are so focused on getting the moisture out, asking if the gun safe can be too dry is a valid question. 

The short answer is yes, as areas too dry can cause wood and steel damage. The best humidity level to have in your gun safe is between 40-50%, which as you will have seen, our recommendations of dehumidifiers will deliver this. 

If you are buying a dehumidifier to remove excess moisture in your gun safe, the air being too dry should not be an issue. 

If you are concerned, a hydrometer will tell you the precise humidity level of your gun safe so you can keep track and adjust where necessary.
