What Are Gun Safe Dehumidifiers?

Whether you own guns for sport, or home defense, responsible ownership means ensuring that they are in peak condition at all times.

Given that the critical components of guns are generally made of ferrous metals, excess humidity can cause pitting and oxidization.

Gun safe dehumidifiers are small dehumidifiers specially designed to fit inside gun safes, or any other safe for that matter.

They differ from the typical Peltier method dehumidifiers you’d find in your home in that they don’t rely on the refrigeration cycle to operate (keep reading to learn how they work!)

Ultimately, a gun safe dehumidifier will reduce or remove moisture from within your gun case and create an optimum environment for protecting firearms from atmospheric damage.

What Are The Different Types Of Gun Safe Dehumidifiers?

With gun safe dehumidifiers you first need to choose between electric or desiccant style.

Desiccant Dehumidifiers

Desiccant dehumidifiers require no power, they have no moving parts, and are a proven method of dehumidification.

These units are usually housed in a canister or sachet filled with hydrophilic (water attracting) pellets.

They can be reusable or disposable, and you’ll usually find that those in a metal canister are able to be recharged by heating them.

They use materials like silica gel as the desiccant – silica gel is something you’re likely to recognize from the small packets that manufacturers include in shoe boxes, electronics packaging, and even in beef jerky packs!

Silica based desiccant dehumidifiers are cost effective, and require no modifications to sealed gun safes.

They present zero risk of fire, and as long as the silica is fresh, or freshly recharged, these are extremely reliable dehumidifiers.

Electric Dehumidifiers

Electric dehumidifiers are a more technologically advanced gun safe moisture control method.

They are usually much more powerful than desiccant dehumidifiers, and are a great choice if you have a lot of humidity in your home.

With electric gun safe dehumidifiers, you are actually using heat to remove moisture from the case.

These units feature a heating element that provides dry warmth, working like a blow dryer to remove moisture.

If you’re actively looking for an electric dehumidifier, the two main types available are horizontal rods and upright towers.

How do Gun Safe Dehumidifiers Work?

Depending on which style you choose, your gun safe dehumidifier will work in different ways to achieve the same end result – reduced/eliminated humidity in the case.

With electric gun safe dehumidifiers, they operate by slightly raising the internal temperature inside the safe.

The aim is to create a stable temperature – as we know, condensation occurs when warm air cools rapidly, so by keeping the temperature constant, we prevent the formation of harmful condensation on guns and ammunition.

Secondly, by keeping an electric gun safe dehumidifier low down in the case, it creates a circulation effect as the warm air rises. The warm, dry air from the dehumidifier displaces moist air, pushing out up and out of the case.

Now, for silica based desiccant dehumidifiers, the beads within the container or sachet are hydrophilic, meaning that they naturally want to take on water.

They absorb moisture from the surrounding air and hold onto it like a sponge.

Once they are saturated, they either need to be replaced, or in the case of ‘rechargeable’ silica, placed in an oven and heated – this pulls the moisture back out of the gel, making them ready to go back to work in your gun safe.

Rechargeable silica canisters do gradually lose effectiveness over time, but they are inexpensive to replace.

What Do You Look For In The Best Gun Safe Dehumidifiers?

Keep an eye out for these must have features when shopping for your gun safe dehumidifier!

Removable Power Cord

If you’re planning on investing in an electric gun safe dehumidifier, look for a model with a quick release power cord, especially if your safe is sealed and does not have a built in power source.

This will help to minimize the size of any hole that needs to be drilled as you’ll be able to easily pass the power cord through and reattach it to the dehumidifier at the other side.

Compact Size

Your gun safe is for guns, ammo, and other valuables that you want to protect – the more space items like dehumidifiers take up, the less you will have to protect the valuables that mean the most to you.

Compact, low volume dehumidifiers should be able to keep the air dry without consuming valuable space.

Recharge Period (Desiccant)

As we mentioned above, some desiccant dehumidifiers require recharging in order to continue absorbing moisture.

If this is the style of dehumidifier you’re considering, look for models with the longest recharge period, that is, dehumidifiers that can go the longest between charges.

Recharge Indication (Desiccant)

If you do choose a desiccant dehumidifier, look for one that has some kind of indicator to show that it is saturated and requires recharging.

In some models the beads will change color, in other models, there will be a gauge that visually shows how saturated the beads are.

Without this, you may incorrectly assume that your dehumidifier is working, when it is actually incapable of absorbing any more moisture.

Final Thoughts On The Best Gun Safe Dehumidifiers

Dehumidifiers aren’t always the first accessory gun owners think of for their safe, but a small investment in one of these important devices can significantly increase the lifespan of some of your most valued items.

Not only that, but keeping your guns rust free and ready to go could also make the difference between life and death in some cases! 

As a final tip, we also recommend keeping a digital thermometer and hygrometer in your gun safe too. This will help you to monitor conditions in real time.

This model from Govee is Bluetooth operated, meaning you can leave the device in your safe and check conditions from your compatible smart phone.
