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.
