If you have a gun safe, you need to have a dehumidifier to prevent moisture from rusting or corroding your weapons. A gun safe dehumidifier is the best way to keep your firearms safe from rust. And this is especially the case if you live in a tropical or moist climate. 

We have scoured through the internet for hours to shortlist the best gun safe dehumidifiers of 2023.

Types Of Gun Safe Dehumidifier

There are primarily two types of gun safe dehumidifier. One is an electric type, while the other is a gun safe desiccant dehumidifier. 

  • Electric units

These are not truly dehumidifiers because they don’t draw moisture from the air. Instead, they work by heating the air and circulating it around. 

This cyclic process prevents condensation development within your gun safe and will keep your guns dry. However, these units can raise the temperature slightly; therefore, you need to place it right at the bottom of your gun safe. 

  • Desiccant units

This type is completely different from its electric counterparts. They operate with the help of special humidity absorbing crystals that can extract moisture from the air. 

The crystals that are there can work like moisture absorbents, and they are supposed to change their colors once they have ascribed all the moisture they can. 

What Features to Look for When Buying a Gun safe Dehumidifier

Humidity level

To go for the right kind of humidity level, you first have to determine the humidity; even your gun is safe. In most cases, the humidity level of your gun safe is going to be around 45% to 55%. 

If there is any humidity above that level, your weapons are going to corrode and rust. Moreover, anything that is lower than this margin will dry your weapons out from the inside. 

This can also lead to deformities and cracks. Therefore, you will need a gun safe dehumidifier that can keep the humidity levels inside your gun safe between these margins, and your weapons will remain in their best conditions. 

Size of the safe

You need to finalize a gun safe dehumidifier based on the size of the gun safe you have. For a small gun safe, you might not need a larger dehumidifier. 

If you don’t have the safe size, you can always measure it and find the cubic feet area of your gun safe by multiplying lengths, height, and width. And then choose a unit according to the cubic feet you have calculated. 

Your geographic location

Geographically where you are located also matters a lot. Areas differ from one another in terms of temperature and humidity levels. If you have your gun safe in your basement, you will need a more powerful gun safe dehumidifier to tackle heavy humidity. 

If you live in a tropical region, you will also need a more powerful gun safe dehumidifier

Desiccant vs. Electric: which one is better? 

Make your choice between an electric or a desiccant dehumidifier. First of all, you need to have some room available in your gun safe if you are thinking of going for an electric unit because it is relatively large. 

You can go for that rod-type as well; otherwise, a desiccant unit is a better option for you. Also, make sure you don’t go for putting holes in your safe for a particular type of dehumidifier. In such a scenario, you will still need to stick with the desiccant unit. 

Can a regular dehumidifier work for my gun safe as well? 

Your regular dehumidifier might work for your gun safe as well, but it all depends upon how close you have placed it on the gun safe and how powerful it is

The area where you live will also matter here because if it’s the tropics, you will need to place a unit inside the gun safe to keep your firearms safe from any rust or corrosion.
