How Does A Gun Safe Dehumidifier Work?

There are two types of gun safe dehumidifiers on the market: desiccant and electric. Desiccant dehumidifiers use silica gel beads to draw any moisture into its collection unit. There’s little setup involved – it’s more of a “set it and forget it” and can last for months. 

An electric dehumidifier works the same way yet may require an outlet nearby. There are some cordless electric dehumidifiers that are rechargeable and work the same way. 

The ultimate goal is to ensure moisture is pulled into the device instead of circulating throughout the safe. It’s an essential tool to ensure gun safety and full functionality.

What Does A Gun Safe Dehumidifier Do?

While gun safes are designed to house and secure your possessions, they’re stored in a dark environment. That leaves them susceptible to accumulating water and moisture inside the safe. If that happens, the likelihood of mold and mildew growing inside increases. Water build-up also leaves guns prone to corrosion if left unchecked. Nothing sucks more than a ruined patina or God forbid… rust.

The dehumidifier ensures any moisture is pulled away from the guns and into one isolated area in the safe. By collecting and storing the water in the apparatus, your guns are less likely to be ruined by the instrument designed to keep them safe and secure. 

What to Look for When Buying a Gun Safe Dehumidifier

When it comes to selecting the right dehumidifier, factor in the size of your safe. Buying a small dehumidifier for an oversized safe makes little sense, as does getting a larger device for a small safe. 

Account for location. Whether it’s in your closet, garage, or makeshift armory, where your safe is matters. If it’s in a space without outlets, it’s safe to assume a desiccant dehumidifier is the way to go. If your safe is exposed or located somewhere by an outlet, consider an electric version. 

Another crucial factor is the model of the dehumidifier. Some are small and portable, like the size of a GPS unit, and some are rod-shaped. As you need to consider the size of the device, fit also matters.

Also, consider how often you’d need to check on the dehumidifier. Whether it’s silica-based, rechargeable, or electric, you’ll want to make sure that after enough time passes, your dehumidifier still works at maximum efficiency. 

If you need to change the beads, recharge it, or make sure the electric model warms the air, look for one that is long-lasting and requires minimal maintenance.

Review of the Best Gun Safe Dehumidifiers

Not sure where to start for the best gun safe dehumidifier? Here’s a list of the best options currently on the market:

Top Pick

Lockdown Golden Rod Dehumidifier




What Recent Buyers Report

Most buyers’ selling points include that while it’s too hot to touch, it won’t burn your guns if one leans against it. The safe humidity stays regulated, installation and setup is easy, and the various sizes allow owners with multiple safes to not be limited in choice.

Why It Stands Out to Us

The Lockdown Golden Rod Dehumidifier is ideal for very humid places. Whether it be in a garage, a closet, in the open, or under a staircase, it’s optimal for various safes. It doesn’t draw too much power, so your electric bill won’t be sorely affected. 

Because it stays plugged in, there’s continuous regulation of humidity and heat within the safe. Additionally, because the product eliminates mold and mildew build-up it protects against rust, corrosion, and metallic degradation. There’s also a lifetime warranty for the product, so should something happen with it, you’re in good shape. 

Bottom Line

The Lockdown Golden Rod Dehumidifier is rated 5/5 on its website, 4.9/5 rating on Google, and 4.8/5 on Amazon. It’s one of the top dehumidifiers in the market. Simply put, this is a can’t-miss product.

Runner Up

Eva-Dry Wireless Mini Dehumidifier

Eva-dry E-333 Renewable dehumidifier, Pack of 1, White Sand



What Recent Buyers Report

When it comes to portability and compactness, the Eva-Dry Wireless Mini Dehumidifier works well for gun safes. Though it needs recharging, it works well for tight spaces to remove moisture and ensure that mold and mildew don’t build up. 

Why It Stands Out to Us

The Eva-Dry Wireless Mini Dehumidifier works well in small spaces and can manage humidity levels extremely well. The device telling you when it’s full of moisture and needs recharging is a big perk for monitoring its progress. 

Being dry and odorless while possessing a low probability of the silica beans spilling out makes it perfect for a “set and forget” environment. Additionally, with proper use and management, the product shelf life is ten years!

Whether the safe is large or small, you can’t go wrong with this product as your go-to gun safe dehumidifier.

Bottom Line

Simply put, this device works. For a safe that’s large or small, stashed away at the bottom of a closet or in a damp and cold garage, this dehumidifier will keep your prized possessions safe. You can’t go wrong here.

Best Budget Option

Snap Safe by Hornady Rechargeable Gun Safe Dehumidifier




What Recent Buyers Report 

Usability for both small and large safes and an indicator to inform users when it’s time to recharge, the Snap Safe by Hornady Rechargeable Gun Safe Dehumidifier gets the job done as a hybrid product. With a long-lasting battery, you don’t need to charge the product frequently. It takes “set and forget” to a new level.

Why It Stands Out to Us

The Snap Safe dehumidifier works as advertised to keep securely stored products dry. It’s excellent at drawing in water to make sure your guns keep from rusting and corroding. Users highly review it as being reliable, safe, and a must-have product.

If you’re looking for something that truly draws down the humidity in tight spaces, you will want to invest in this product. It does as advertised and has a long shelf life. Its reach of 500 cubic is astounding. A portable dehumidifier with that kind of range is hard to come by. 

Bottom Line

The Snap Safe dehumidifier is worth the investment. Accurate indicators are a big asset for a desiccant tool; saying “Wet” and “Dry doesn’t get much more accurate than that. Who doesn’t like things spelled out for them?

Browning Safes Flexible Everdry Electric Gun Safe Dehumidifier



What Recent Buyers Report

With the ingenuity of the design, the flat surface of the Browning Safe Flexible Everdry Gun Safe Dehumidifier is hit or miss. The LED indicator is a good feature to have, but between not heating to optimal temperature or not being sturdy, people appreciate the aesthetic but not the function.

Why It Stands Out to Us

First and foremost, a flexible gun safe dehumidifier? Who would think one of those exists? Typically a dehumidifier that gets to a high heat would be rigid, but to have one that bends to whichever corner you want to stash it in is unprecedented. 

Yet, here we are with the Safe Flexible Everyday dehumidifier. An indicator light that tells you the product is working is an unconventional yet extremely neat option for keeping your guns in perfect condition. 

Bottom Line

If you’re looking for something less rigid and gets the job done, consider investing in the Flexible Everyday dehumidifier. It fits virtually any safe, is fully electric and will keep your guns from rusting or corroding.

Dry-Packs 750 Gram Silica Gel Canister Dehumidifier

Dry-Packs 750 Gram DP750CAN Silica Gel Canister Dehumidifier - Moisture Indicating



What Recent Buyers Report

Some buyers report that the beads effectively retain moisture yet need to be recharged every few days instead of weeks or months. The 750g Dry Packs Silica Gel Dehumidifier is effective yet may require more frequent maintenance than most people want.

Why It Stands Out to Us

The Dry Packs is a solid alternative to the rechargeable or electric gun safe dehumidifiers. A low-maintenance, fully-manual desiccant dehumidifier is as effective as an electric one. The true meaning of “set it and forget it” you’ll need to reheat it on occasion, but you’re in good shape with just one or two.

While the product is not suitable for a large space, it’s perfect for a small closet-sized gun safe. It will effectively draw moisture and virtually eliminate moisture buildup.

Bottom Line

It may not be the most effective tool on the planet, but little routine maintenance goes into this product. Once it’s full, throw it in the oven to dehydrate, throw it back in the safe, and you’re good to go once more.

Advantages of Investing in a Quality Gun Safe Dehumidifier

In some way, shape, or form, I’m sure you’ve experienced unwarranted water damage or water buildup in dark and confined quarters, only to have your belongings ruined and unsalvageable. A safe is no different, and a gun safe is even more precious. 

Guns are expensive and should be taken care of as any other prized possession would. That means that investing in products to enhance and secure your storage unit is a must. 

Whether you plug it in, charge and recharge, or nuke it every few weeks, investing in a quality dehumidifier removes fears of mold and mildew buildup, rust and corrosion, and results in peace-of-mind that your commodities are well maintained. 

With a fully-electric version, it’s truly “plug-and-play.” If it’s more manual, it’s “set-and-forget.” If it’s rechargeable, just check on it every few weeks or months. You can’t go wrong with whatever version fits your needs. 


When it comes to doing what you must against what you should, you MUST invest in a gun safe dehumidifier and SHOULD take the time to figure out the right one for you. Not all dehumidifiers on the market will work for you, but there will be one that does.

People Also Ask

Doing research does not guarantee finding the answers. That said, two popular questions that come up with safe care are below. Take a look at the answers and factor that into your decision. They will greatly benefit your search for the right product.

Where do you put a dehumidifier in a gun safe?

The best places are near the very back of the safe and right by the door on either side. The size of the safe will have a great impact. If it’s a large safe, consider the very back; conversely, if it’s a small one, by the door works well.

What is the ideal humidity for gun storage?

The ideal temperature for a gun safe is 50℉. Stored in a room that’s close to or at room temperature, having a gun safe stored much cooler reduces the likelihood of water building up inside. Getting a dehumidifier will help you say, “problem solved!”
