Gun Safe Dehumidifier: Top Electric and Wireless Models


If you own a gun safe, you may want to invest a little more for it than your guns, ammo, and other treasures. One of the biggest issues that people tend to have with a gun safe is the humidity inside of it becoming too much. This can lead to a musky smell inside and/or damage your valuable items inside of it. A gun safe dehumidifier can really help fix this problem. Some gun safes have a dehumidifier built in, but for those that do not, you may definitely want to consider purchasing one or two.

What Are Gun Safe Dehumidifiers?

A dehumidifier is a device that works by removing moisture from the air. They are great in a home that may be closed up for a while or homes that are in naturally damp areas of the world. They can cut down on allergens, dust, mold, mildew and a lot of other things that may affect the air quality inside of a home, basement, or attic. In a gun safe, they work the same way. Many people do not open up their gun safe very often. Therefore, air does not circulate inside of it. Changing temperatures in the room outside of where it is located can cause the safe’s internal temperature to fluctuate and allow moisture to develop. This can cause a musky odor to occur and increases the potential for mold and mildew to set in.

Types of Gun Safe Dehumidifiers

There are several ways that you can dehumidify your gun safe and several types of dehumidifiers available for them. Each has pros and cons, but for the most part, the pros will far outweigh the cons. Without something in there to keep your safe moisture free, you will end up with important papers that are discolored and guns or other metals that may become tarnished or rusty. The three most popular choices are listed below:

Silica Gel

This gel is what many people use to keep their gun safe dry inside.  because it is the little packet of stuff that comes with new items. If you purchase a gun safe, even one with a built-in dehumidifier, you will most likely have a silica gel pack inside of it to keep it moisture free while boxed up in a store waiting for you to take it home. They are a part of what is considered a desiccant dehumidifier and work by soaking up moisture like a sponge would do. They are a cheap option to use and easy to put in wherever you need it. You should change them out every couple months, but most can be put into an oven, dried out, and reused as per the manufacturer’s directions. Silica gel does not prevent moisture from forming, but it soaks it up when it forms.


An electric gun safe dehumidifier is one of the most expensive options, but many people feel that it is well worth it. It controls the moisture or condensation in your safe by providing the interior of it with a constant heat source. It resembles a rod, often it is called the “goldenrod” because it is nothing more than an exposed heating element that evaporates all moisture inside of the gun safe. However, electric does mean that you will have wires that must stay plugged in at all times. Some safes have electric outlets inside of them so it is easy to plug in. For safes without an electric outlet inside, you will have to run the wire through the door or create a small hole for it to pass through.


A wireless gun safe dehumidifier is a battery powered unit that sits inside of your safe. The battery life is usually fairly good and it works to add heat to the inside of your gun safe. They are small, they are portable and work very well, especially if you are willing to use silica gel alongside it. There are some that include silica gel inside of them and as the fan circulates the air, the silica gel absorbs it. Most battery operated products have a lifespan of around 10 years. The only issue is that you do have to change out your batteries on occasion. If you forget to change the batteries your valuables could get damaged. We recommend setting some type of reminder if you are not a person that opens your gun safe often.

Pros and Cons of a Gun Safe Dehumidifier

The pros of a dehumidifier being inside of your gun safe are simple. If you do not allow moisture to thrive inside of it, you will never have to worry about papers developing black spots or guns that no longer work because they are so rusty.

The cons of using a dehumidifier will depend mostly on the type that you choose to use.

If you choose the electric type, having wires is a requirement. This can increase your power bill. They are also pretty expensive to purchase or replace.

Wireless versions do wear out, which means you must replace them every so often and you do have to occasionally remember to check the batteries. Some need batteries every 4-6 months so you have to weigh that cost versus paying a small amount for your electric bill every month. If you forget, you could end up with mold or mildew despite your best efforts. In some battery powered dehumidifiers, they use silica gel to ensure that everything stays dry.

The biggest type that most people avoid because of its inconvenience is the desiccant dehumidifiers. Depending on the type that you use, you may have to deal with extreme moisture that drips before you realize it is full. Some of the silica gel sponges have to be rung instead of baking in the oven to dry them. Either way, it can be messy to deal with and requires checking more often.
