Best Gun Safe Dehumidifier – 3 Top Options for 2020

If you have purchased a gun safe, then you have taken the first step in protecting those around you from misuse of your guns. A good gun safe ensures that a gun is not used mistakenly, or taken by anyone who should not be using one of your guns. But, have you given full thought to the safety of your guns inside the safe?

Sure, they are protected from the outside world, but are you protecting your guns from the one thing which can damage them even behind the thick layers of steel? I am, of course, talking about moisture. Moisture can eat away at your guns. Moisture can cause them to seize up. It can cause parts to grind together.

A gun safe dehumidifier can remove that moisture for you. All we need now are some gun safe dehumidifier reviews, and I have three of the best for you. We look at 3 different types of gun dehumidifier: silica based, battery powered and mains powered.

Eva-Dry Mini Dehumidifier

The great thing about this small and compact dehumidifier is that it does not use batteries. This means that you will never again forget to replace the batteries and lose the dehumidifying power of the unit. No batteries needed also means that you do not have to shell out for replacements every so often. The lack of a power source also means that this dehumidifier works soundlessly. There will be no annoying humming coming from your gun safe to distract you.

The unit uses silica gel to absorb the water. You can use this device to absorb moisture over an area of 333 cubic feet. When you open your gun safe, you will notice that the front of the unit has crystals which will display the water level in the silica gel. The colors of the crystal will change when the water level increases, to remind you when you should change the gel inside. If you are not going to open your gun safe regularly, then you should schedule times to check on the water levels in the dehumidifier. The crystals are changed by the moisture and not power, so you do not have to worry about batteries for that either.

The dehumidifier has a capacity of 4-6 oz. This can take anywhere from two to four weeks. Once the water levels reach maximum (or even before), you can take the dehumidifier and plug it into any outlet. This will power the unit and force out the moisture, returning the gel and crystals to their original state. You can repeat this for up to 10 years.

One of the best things about this dehumidifier is the low cost. For the standard of service, you get from this small unit, you would expect to pay a lot more.

Stack-On Cordless Dehumidifier

This is another dehumidifier which is small and compact. It will take the moisture from a space of up to 100 cubic feet and will work for up to 6 weeks before needing to be recharged. This is one of the features which I love. You simply plug the device into any outlet and let the main power replenish the juice in the batteries. No need to spend your hard-earned money on replacement batteries. While the dehumidifier is plugged in to recharge, it will also remove the moisture from the device. This means that you do not have to worry about manually removing the water or replacing any gel packs.

There is a moisture gauge on the front of the unit to tell you how full the device is. The front will also show you how much charge is left in the battery. This allows you to check everything about this unit with one quick glance.

One of the defining features of this unit is how easy it is to use. There are some other dehumidifiers out there which need you to drill holes in your safe to allow the moisture to flow and be captured by the device. This device needs none of that (and why should it? I hate the devices which ask you to damage your safe).

One other thing which I like about this device is that you can choose where you want to distribute the moisture contained. You can use the dehumidifier as a humidifier in a dry room.

Goldenrod GunSaver Dehumidifier

This is one of the best performing gun dehumidifiers that we could find. A lot of time and effort has gone into creating a device specifically engineered with guns and gun safes in mind. This dehumidifier will deal with any moisture that may get into your safe. And, do you know what the best part is? It does all of this for a very affordable price. Your guns may have set you back a lot of money, but protecting your guns need not.

This unit mounts to your safe, with wires which will run through the pre-drilled holes which come with most safes. Once you have the rods mounted and the unit plugged in, you do not have to worry any more about it. There is no need to recharge batteries or empty the water. This device gives your guns protection 24/7.

This unit will provide great coverage for your safe and actively increases the heat in the safe to stop condensation from forming. If you have expensive guns, then this is the dehumidifier to trust them with.


It does not matter if you have guns or expensive guns, they all need protection. It is not about protecting the money they cost you, it is about protecting them so that they can protect you, and so that they are not a danger.

A gun which does not work properly can put your life in danger. If you are attacked, you may not be able to retaliate. If you are able, and the gun is not working as it should, you can pose a second danger to yourself. A gun safe humidifier will keep your guns in prime condition.
