What Are The Best Dehumidifier For Gun Safe Options?

Eva-dry E-333 dehumidifier for gun safe use

A dehumidifier for gun safe protection is a great investment. We know that there are many reasons why using a gun safe is a good idea, including:

  • A safe can protect your weapons from theft.
  • It can even provide protection against fire.
  • It will protect your firearms from damage that can result from too much moisture in the air.

However, some people don’t realize the importance of gun safe humidity control.

When gun safe moisture control is not regulated, the moisture content can increase. This leads to corrosion forming on metal. Corrosion on guns leads to rust and many other problems.

Corrosion can have a huge impact on how your guns operate and how long they will last. Corrosion on firearms can lead to issues with firing accuracy and consistency. Plus, for collectors of antique guns, corrosion will whittle away at the value of these items over time.

This is why you need to consider adding a dehumidifier to your gun safe. With this in mind, make sure to have a look at a list of the best gun safe dehumidifier reviews below.

But to begin with, a bit about…

The Different Types of Gun Vault Dehumidifiers

There are two very different varieties of dehumidifiers that are effective in regulating the humidity in a gun safe. They are the:

  • Electric dehumidifier, and
  • Desiccant dehumidifier.

Electric Dehumidifier

With an electric dehumidifier for use in a gun safe, you plug it into a power outlet. The disadvantage to using an electric dehumidifier is that it requires a hole drilled through the steel wall of your gun safe. The hole allows the electrical wires to run from the wall power outlet to the dehumidifier sitting inside the safe.

The electric dehumidifier also requires a power connection at all times to work.

Electric dehumidifiers are the most popular choice for gun owners for one specific reason… they are excellent at drawing moisture out from every corner of a steel-walled safe.

Desiccant Dehumidifier

A desiccant dehumidifier for use in a gun safe uses a form of drying agent to draw moisture from the air. In other words, it works like a sponge to draw up all the water into the drying compound.

There are a few advantages to using this kind of dehumidifier. The most obvious benefit is that it does not need electricity to operate. This means no drilling of holes into the safe and no wires running from it.

This also means the gun safe can sit anywhere in your home without you having to locate it near a power outlet.

Another great feature about desiccant dehumidifiers is that you can renew or reuse them. Depending on the specific model of the dehumidifier, the drying compound can last up to several months.

The renewing or recharging of the compound used in a silica gel style dehumidifier is easy. As these beads draw moisture from the air, you need to dry them out to keep working. Baking them in an oven dries them which ‘recharges’ them for further use.

Do You Need To Use a Gun Safe Dehumidifier?

Gun safes are often installed in cool, dark places that don’t get much air circulation or light. These environments are often damper than others. Having a high moisture content in the air, as well as in your gun safe, can have a damaging effect on your gun, ammunition, and anything else of value.

Any moisture sealed within the safe will condense on the items within it when the temperature cools. Besides preventing mold and mildew from growing on all surfaces within the safe, gun safe dehumidifiers also prevent rust and corrosion from forming as a result of the condensation build-up on your precious metal items.

Gun safe dehumidifiers are designed to extract moisture from the air within the gun safe and/or circulate warm dry air 24/7, drying the air and protecting everything within the safe from the damaging effects of moisture build-up.

Unless you choose to purchase a gun safe with a dehumidifier built into it, you should install a dehumidifier in your gun safe. Gun safes with built-in dehumidifiers are not common, so most people opt to install a dehumidifier into their gun safe using one of the options reviewed above.

Where Do You Put A Dehumidifier In A Gun Safe?

There are two main locations inside a gun safe where a dehumidifier works best. Either on a shelf inside the safe or on the safe floor. Either location can work ok, however many people prefer to install their gun safe dehumidifier on the floor due to warm air from the dehumidifier rising to protect everything in the gun safe better.

Where Is The Best Place To Install A Gun Safe?

There is no ideal place to put a gun safe, however, there are factors that will help determine the best location. For example, you may wish to consider the possibility of water damage, a fire, or the potential for burglary (see below).

Is It Ok To Keep A Gun Safe In The Garage?

A garage is a bad location for a gun safe. This is for a few reasons. Many of the tools stored in a garage contain fuel and chemicals that are flammable. Should a fire occur, you risk losing your guns as a result. Also, garages are often separated from the rest of the house (if not a separate building, then behind a closed door). They are also sometimes easier to gain entry to, and contain a lot of expensive equipment that can quite easily be sold for cash. For these reasons, thieves often target garages, which means that storing your gun and ammunition in a gun safe dehumidifier in the garage may not be the best option.

Is A Gun Safe Dehumidifier A Good Investment?

Yes, it is. By being able to measure and monitor the humidity level where your guns are stored, you will be able to prevent them from getting damaged. Too much humidity can cause corrosion and gun stocks can become damaged when the humidity is too low. Therefore, regulating the humidity in your gun safe is vital.

What Humidity Is Bad For Guns?

The best humidity level for gun storage should be between 30% and 50% at a room temperature of about 70°F / 20°C. The NRA (National Rifle Association) states that should the air become dryer than 20% relative humidity (RH), gun stocks may be negatively impacted. Above 50% RH corrosion can form which can also damage guns and ammunition.

Final Thoughts on Dehumidifiers for Gun Safe Use

Protecting your investment comes in many different forms. It can include insurance, alarms, and dehumidifiers. By implementing gun safe moisture control systems, it will keep your firearms safe from their most dangerous foe, corrosion.

Rust can destroy the look, feel, and value of your gun. This is why it is important to not only keep your gun maintained, but to put in place gun safe humidity control. This is the best way to keep corrosion at bay.

As we have outlined above, there are many dehumidifier options for gun safe protection. So depending on the size and location of your gun safe, you should be able to find a solution to protect your gun collection.
