Gun Safe Dehumidifier

Why Every Gun Aficionado Needs A Gun Safe Dehumidifier?

A Gun Safe Dehumidifier?

You have gone through all of the effort and expense to house your guns in their very own safe, thinking that the safe itself is enough to keep them protected.

While it’s true that the safe does a brilliant job of protecting your guns from being stolen and it keeps them out of reach of your children, what about the silent and invisible force that is causing havoc on your guns from the inside…


A few of the modern and more expensive gun safes will come with built-in gun safe dehumidifiers but the majority won’t so it’s up to you to install the necessary precautions to prevent your guns and ammunition from falling victim to rust.

This short guide was designed to spread awareness of the underlying issue of gun safe moisture as well as to provide an understanding of what a gun safe dehumidifier can do to help eradicate the problem at its source.

Firstly, let’s dive into what a gun safe dehumidifier is and how it works.

What Exactly Is A Gun Safe Dehumidifier?

As the name suggests, a gun safe dehumidifier is a device that dehumidifies your gun safe and removes excess moisture from its surrounding areas.

Gun safes can withstand a lot of damage from external forces such as fire, water, ice and human interference but unless the safe has a built-in mechanism to deal with excess moisture, problems with rust and mould are inevitable.

Gun safes are dark and have little air circulation. These two factors combined make the perfect environment for rust to develop on the inside of the safe as well as on the smaller pieces of metal inside your guns.

The exterior of your guns may be rust-proof but there are little pieces inside that surely are not.

Dehumidifiers are simple tools that help to remove excess moisture from the air, ultimately protecting the safe and all of its contents from moisture related problems.

With that being said, not all humidifiers are the same. There are actually two main types of gun safe dehumidifiers on the market today.

Let’s look at them both so that you have an understanding of which type is the better option for you.

Electric Vs Desiccant Gun Safe Dehumidifiers

Both types of dehumidifiers work the same. They both remove excess moisture from the air, they just do it in slightly different ways.

The most expensive, most popular and most practical solution for controlling gun safe moisture is an electric dehumidifier:

Electric Dehumidifier

Electric dehumidifiers work by producing heat which ultimately evaporates any excess moisture in the surrounding areas. Electric dehumidifiers work quickly and are extremely reliable.

The only downside of electric models is the fact that they generally need a constant power supply for them to work. If your gun safe doesn’t have a designated hole for a power supply cable to run through, you may have to drill out your own.

The safe must be kept close to an electrical power outlet too which isn’t always possible for some people.

To combat this issue, you can try and find a rechargeable electric dehumidifier. They work in exactly the same way, the only difference being that they can be recharged instead of requiring a constant supply of power.

Desiccant Dehumidifier

If you don’t like the idea of running electricity through your gun safe, the next best option is to choose a desiccant dehumidifier.

Although they aren’t as popular as their electrical counterparts, they are typically a lot cheaper and will work just as well.

Desiccant dehumidifiers simply act as a sponge, wicking any excess moisture out of the air and storing the water inside itself.

The obvious benefit of choosing a desiccant dehumidifier is the fact that it requires no electricity to work, simply add it to your safe and you are ready to go.

The downside?

Desiccant dehumidifiers only work for a certain amount of time before they either need to be replaced or “Baked” in the oven to remove all of the stored moisture.

If you don’t want to go through the hassle of replacing the sponges every few months, you will be better off with an electrical dehumidifier but if you want to save some money and don’t mind the extra bit of work, a desiccant model is perfect for you.

What Benefits Can I Expect From Installing A Gun Safe Dehumidifier?

Now that you know what a gun safe dehumidifier is, how they work and also the different options available on the market, let’s quickly run over the benefits that you can expect from installing one in your own gun safe.

01. Rust Protection

Although guns are often advertised as being rust-resistant, it’s not always the case. The outer shell of the gun may be rust-resistant but there will be springs and other little tidbits inside the gun that are not safe from all of the elements.

It’s not only the gun that is vulnerable to rusting either. The inside of the safe itself can start to rust, ruining the safe to the point where you may have to shell out for a new one.

Installing a dehumidifier will stop any rust in its tracks, leaving your gun, your safe and everything else that’s inside it, rust free

02. Protection From Mold

Rust is not the only problem that can arise from too much moisture in your safe. Mold can quite easily grow on any sort of sponge that may be lining the shelves of your safe and even any documents that you keep inside.

If you want to keep important documents inside your safe then you will undoubtedly need to install a dehumidifier to safeguard them from mold damage in the future.

Since mold is caused by an excess of moisture in the air, a dehumidifier is the perfect tool for eradicating the issue.

03. Keep Your Ammunition Dry

As a gun owner, you probably already know how temperamental ammunition can be. Whether you make the ammunition yourself or purchase boxes from a gun store, all ammunition has a shelf life.

If the ammunition is stored in a humid environment, the shelf life can reduce dramatically, leaving you with ammunition that doesn’t perform as well as it should.

It goes without saying that keeping your gun safe at a consistent and reasonable humidity will help to maintain your ammunition for a lot longer than a safe with high humidity.

Do your ammunition a favor and get yourself a dehumidifier as soon as possible.

Understanding What Features To Look For When Purchasing

If you have spent any time searching the internet for gun safe dehumidifiers on the market, you will have probably realised that there are way too many to choose from.

How do you choose the best product for the job if you don’t know exactly what you should be looking for?

Here are a few things to keep in mind when shopping for a dehumidifier for your gun safe:

01. Your Budget

As with most modern day products, safe dehumidifiers come with a wide range of price points to choose from. The cheaper dehumidifiers are typically desiccant and will use silica beads as the absorption agent.

Since silica beads are cheap to produce, a desiccant dehumidifier will be the cheapest option.

If you are the type of person who rarely checks their gun safe (Home Protection Gun Safes For Example), you may want to stretch your budget as much as possible in order to purchase a more expensive electrical dehumidifier as these require no maintenance.

Simply set them and forget them.

02. Size And Coverage

Another crucial factor to keep in mind is the size and the coverage of the dehumidifier.

Imagine spending a lot of money on a brand new dehumidifier just to realise that it’s too big and won’t fit in your safe.

On the other hand, imagine purchasing a new dehumidifier only to find out that it doesn’t cover the entire length and breadth of your safe, leaving pockets of moisture in the corners to do their damage.

One simple way to avoid these two mistakes is to measure the insides of your gun safe.

Once you know the sizes of the side panels as well as the cubic capacity of your safe, it’s just a case of reading the manufacturers product description to double check that the dehumidifier is good enough for the job.

03. Ease Of Installation And Use

Every dehumidifier on the market will come with manufacturer descriptions to help make the installation process as simple as possible, but it’s worth knowing beforehand that certain dehumidifiers will be easier to install and easier to use than others.

Silica or Desiccant dehumidifiers are the easiest to install but require the most upkeep.

Once the silica beads have saturated, you will need to either purchase a new absorption agent or go through the steps to empty them.

Electrical dehumidifiers require less maintenance but may require additional steps throughout the installation process. If your gun safe already has holes built in for a power supply, the job will be surprisingly simple.

However, a lot of gun safes will not so it’s going to be up to you to drill out the holes yourself.

Drilling random holes into a safe can weaken its structural integrity so it’s always recommended that you contact the manufacturer to find out which parts of the safe they recommend drilling your hole.
