Gun Safe Dehumidifier Buying Guide

There is a question that always comes up regarding a Gun Safe Dehumidifier. What is it you need the gun safe dehumidifier for? The following is a discussion that will help elucidate the query.

The main purpose

The dehumidifier has a true intention of serving. Its primary purpose to make sure that there is no condensation formed inside the gun safe and, more importantly, on any of the weapons.

Condensation seems to be a mortal enemy for the guns. Metals rust due to condensation, and the safe has a moldy, nasty stench that comes off, and you can never get out of it.

Condensation happens inside the safe due to the change in temperature or also in more humid areas. 

These can happen at any place after a hunting day during snowy weather or during the rainy months.

Why use a Gun Safe Dehumidifier?

Do you own a gun safe? Well, you probably spent the right amount of money on the safe and the guns. Wouldn’t it be awful if those guns get destroyed because of a lot of moisture?

Well, a gun safe dehumidifier protects your investments by removing the extra moisture in the safe. One thing to keep in mind when purchasing a dehumidifier is whether you have a power source or whether you need it to be portable.

However, we found the top choices for each application. Before you purchase a gun safe dehumidifier, I would highly recommend reading the reviews.

Not only do you find out which safe may be best for your use, but there may be tips and tricks to attach the dehumidifier.

Different types of dehumidifiers

There are two main types of dehumidifiers.


The electric dehumidifier

Some other types of dehumidifiers

Although a Gun Safe Dehumidifier is overlooked much as an accessory, yet its importance is no less to be avoided. 

The gun safe dehumidifier would keep the humidity level in the safe all right and at a proper level so that the guns and the metals protecting your guns are kept from rusting. The dry rod humidifier, as discussed, works well.

The air is heated by the rod and then rises at the top of the gun safe, which is replaced again by the colder air. This air movement keeps happening continuously.

This process will raise the temperature of the guns to at least 3 degrees and avoid the formation of moisture and thereby rust on the guns. 

The other options like the Eva-Dry dehumidifier will require batteries to work so that if the gun is kept away from an electrical outlet, this works best for you.

This is a non-toxic solution and different from the bags of calcium chloride. This is filled with silica gel to absorb moisture and lock that in.

The device is filled with silica, and it is again renewed by plugging it into the power switch. The indicator will show a blue light, and then the dehumidifier can be kept inside the safe.

It is now ready to work and keep things dry. The device is a helpful one, and this can be used for up to ten years.

Rechargeable Vs Heated Rod Gun Safe Dehumidifiers

To prevent moisture from building up inside gun safes, one can make use of gun safe dehumidifiers. There are different types.

There is the rechargeable dehumidifier, and this consists of a tiny plastic container with silica gel inside. 

These are crystals that serve to absorb water. These have no parts that move, unlike thermo-electric dehumidifiers, and so one need not worry about any noise.

These gels are also tiny, as well as lightweight. 

They can be kept or hung inside a closet or kept in the corner of a gun safe, as required.

When these crystals are filled to the brim – they change in color, or an indicator may change in color to notify the gun safe owner that the crystals are saturated.

Usually, the period is about 4 to 6 weeks.

When the crystals are saturated, the dehumidifier will then need to be recharged. This can be done by connecting the gun safe dehumidifier to a power socket for about 10 hours.

So it is important for the safe to be close to a power socket, or at least for you to have an extension cord if there is no power outlet near the safe.

The electricity will work to give heat that will dry up these silica gel crystals.

Many feel that these rechargeable dehumidifiers rank highly or are the best when what one wants exactly is a dehumidifier that does not make a lot of noise, does not cost a lot to operate, and is small in size, so it fits snugly inside of one’s gun safe.

Before buying a dehumidifier, consider the size of your closet or gun safe. Also figure out if you are okay with using one that you will need to be recharged regularly, or if you would instead make use of a light bulb that will do the job, too.

But with these, you run the risk of the filament burning out, and moisture building up inside your gun safe.

Gun Safe Dehumidifiers and Closet Dehumidifiers

If you have ever opened the door to your closet and noticed a musty, moldy stench, were you surprised to discover tiny dots of mildew on clothes you have not worn for a certain amount of time?

This experience is not rare and can be avoided by making use of a closet dehumidifier. Inside clothes where clothes are jam-packed very carefully, moisture can bring about these problems.

There are times when we may put away clothes that are still somewhat damp, like maybe our raincoat, or a pair of shoes that got wet in the rain.

This moisture may be small in amount, but keeping these stored in a closet also means that there will not be much air that can cause these tiny droplets of moisture to evaporate.

The air inside cabinets is generally static, and air does not circulate inside closed spaces such as these. When this happens, the air gets trapped in tiny pockets between clothes.

The problem begins if or when the temperature drops at night, because those small droplets of water will go through the process of condensation, and mold and mildew can develop.

In the context of gun safes, this sort of problem can develop when there is some humidity in the air.

While it is true that air inside one’s gun safe may be static and dry, it can interact with air and humidity in the room – every time we open our gun safe door. 

This can cause condensation to build up inside a gun safe, and this can cause the metal that guns are made out of to destroy.

This type of problem can generally be avoided by making use of gun safe dehumidifiers.

One particular type can heat up to 140 degrees Fahrenheit, ensuring that moisture does not build up inside your gun safe, and so your guns and other valuables are kept safe from any damage that moisture may cause.
