Where To Put Dehumidifier In Gun Safe

Whenever we talk about guns, the first thing should consider is safety. To keep firearms safe and secure we must need the best quality gun safe. Gun safes are highly secured and designed to be protected from intruders and burglars.

Nobody, especially unauthorized persons, can enter into the safe except with a highly equipped drilling machine, but there is an enemy which can cause much more trouble, that is the moisture. Lack of airflow inside the safe increases moisture which results in rust and mold being caught in the guns and safe.

Moisture accelerates the formation process of the rust inside the chilled steel of the gun and the safe. This is why we need to control the moisture and humidity inside the safe. In this case, a dehumidifier is a must.

A dehumidifier is a device that helps control moisture and humidity level in the air. However, if you want to ensure maximum performance of the dehumidifier then you should put it in a suitable place.

Dehumidifier rod can be placed on the bottom of the safe to get maximum performance. You can put it at the front side, near to the door, or deep inside the safe, near to the back of the wall. Most of the gun safe contains predrilled holes at the bottom to pass the wire through. So, it would be very helpful for you to pass the cord of the dehumidifier and plug it on the socket.

Another place is in the middle of the inside of the back wall. In that case, your gun safe needs to have predrilled holes at the back to pass screw and wire. If it doesn’t come with holes then you can drill holes as per your requirement.

Best place for desiccant based dehumidifier and moisture absorber

If you are in search of a non-electrical dehumidifier then the desiccant based dehumidifier is the best option for you. It contains silica gel beads to absorb moisture from the air. This type of dehumidifier can be recharged. There are also moisture absorbers that require baking on the over after a certain time.

A desiccant based dehumidifier can be placed inside the selves of the gun safe. It also contains plug on the back to hand at the wall of the safe. For moisture absorber, the self is the best place. Try to place it to the middle so that it absorbs moisture easily from all corners. But if you don’t have that space in the middle you can put it on top and bottom.

Best place for silica gel bag

Silica bags are the most commonly used dehumidifier at the present time. These bags can be placed in any corner of the gun safe. Although silica beads are placed inside the bag preventing direct contact with the others, it should not be touched with firearms and valuables inside the safe. Like other moisture absorbers, a silica gel bag requires to bake on the oven when it completes absorptions capacity.  

Why finding a suitable place is important?

Finding a suitable place is really important to get the highest performance from the dehumidifier. If you have come to this point means you have already studied where a dehumidifier should be placed inside the gun safe. Setting up a dehumidifier in an inappropriate place may result in uncontrolled moisture and humidity inside the safe.

How to choose the right dehumidifier model?

Right now there’re basically two types of dehumidifiers on the market. One is being electric and the other being desiccant based dehumidifier. Dehumidifier rod is operated by electricity and desiccant based dehumidifier requires to be baking or recharging.

You need to choose the perfect dehumidifiers based on your gun safe area and location. If you have an electrical plugging outlet near your gun safe then obviously you should choose the dehumidifier rod. On the other hand, if your gun safe is far away from an electric outlet then you can choose a descant based dehumidifier.

If your gun safe is too big you can choose both electric and desiccant dehumidifier. However, you can use a gun safe hygrometer to measure the effectiveness of your dehumidifier and decide which model is perfect for your gun safe.

Do gun safe dehumidifiers really work?

It has been proven that gun safe dehumidifiers play a crucial role to reduce excess moisture. As you know, most of the gun safes are made of metal steel or iron, so it is essential to keep them moisture-free to avoid rust. The dehumidifier works perfectly well to reduce the moisture and humidity level at an acceptable level.

How many dehumidifiers should I use?

It totally depends on the size of the gun safe and the number of guns present. Normally people use a single dehumidifier but if you have a large size of the gun safe then you can use more than one.

We would like to request you to use a hygrometer to measure the relative humidity level inside the gun safe. If a single dehumidifier can maintain acceptable humidity level inside the gun safe then you don’t need to use more.

However, one dehumidifier is not sufficient then you can use more dehumidifier to control ambient at an acceptable level.


Humidity means the presence of vapor of water in the air which is invisible to the human eye. Humidity varies according to the condition of the region. We know that steel and metal become vulnerable with the contact of the humidity.

Thus the gun safe and guns are not safe without a controllable moisture level. When it comes to the matter of controlling the moisture of the air, there is no alternative to the dehumidifier.
