Updated: January 1, 2020

Gun safe is a great way to protect your firearms from theft. Plus, it can be ideal for storing other kinds of valuables that you have, including such things as gems, jewelry, media files, important documents, and the like.

While a gun safe is a great purchase, many don’t realize that a huge issue they could face is the buildup of humidity within the safe. In fact, some report that the safe that they purchased continuously allowed humidity and condensation to build up in the safe until there were puddles of water. This will damage your valuable documents and media and cause your firearms to rust.

The solution to this problem is to purchase yourself a gun safe dehumidifier. These handy products will greatly reduce the amount of condensation that can occur to virtually nothing, giving you that added protection to guard the possessions that matter to you most.

Types of Gun Safe Dehumidifier

To begin with, it is important to know that there are two different kinds of dehumidifiers to use in a gun safe. The two options are the desiccant and the electric options.

#1Desiccant Dehumidifiers

This is a product you are probably quite familiar with already, especially if you have bought clothes or other products where humidity can damage the product. The desiccant dehumidifier is really nothing more than those little gel packs you have frequently found in products.

The way it works is quite simple. The gel contained in this product acts very much like a sponge, sucking up all the moisture that is in the air. In a safe, especially one that it is housed in a basement, you can be sure that humidity is going to build up in the safe, with this most likely being a problem during warmer months.

The use of a desiccant dehumidifier will help to eliminate excess humidity that can build up during the safe, but these particular kinds of dehumidifier packets only work for a certain time before you need to replace them. This is usually no more than a few months at most.

#2Electric Dehumidifiers

The electric dehumidifier is the more common option for some, primarily because they can control the humidity levels within the safe. Some do not want to completely remove all moisture from the safe, as that can dry out money, documents, and other valuable objects to you. Setting the dehumidifier to something like 10% ensures that the amount of moisture is regulated but not removed completely. There are two types of electric dehumidifiers:

  • Corded
  • Battery powered

Each has their advantages. A corded unit will run as long as the moisture level has not been exceeded, but it requires you to drill a hole in the safe which ruins a fire or waterproof safe. The power pack removes this problem, but requires you to recharge the dehumidifier on a regular basis.

How to Make the Right Choice?

No matter which kind of dehumidifier you select, you should be aware that the type, electric versus desiccant, is not the only features related to these kinds of products you should be aware of. There are other factors you want to consider, which include the following:

  • Lifespan. Most of the very best dehumidifiers will last for at least 10 years. Check with the manufacturer and with reviews that you find online to make sure that you’re getting one that will last for some time.
  • Source of Power. If you do not want to use a dehumidifier that requires a cord, especially if you are using it inside your safe, you must understand that you will have to drill a hole in your safe. That may not be a good option for you, so you want to get something that is either battery-powered or requires no source of power at all.
  • Size. Not every dehumidifier you will find will fit inside your safe. You want something that will accommodate what you already own, or a dehumidifier that will work to reduce moisture even if it is not inside the safe.
  • Indicator System. When your dehumidifier needs to be recharged or it needs to be emptied of the moisture it has absorbed, you want to know. There are dehumidifiers that will provide you with the proper indicator lights if that is what you are looking for. This can be a valuable feature.
  • Coverage. The amount of space that the dehumidifier can cover is important as well. If you are only going to place it inside the safe, then maybe this is not that big of a deal. But if you are purchasing one to be used in the room where the safe is contained, you want one that can handle a large area.
  • Safety. One of the chief complaints you will hear about some rechargeable dehumidifiers is how hot the device gets while it is being recharged. While they are still perfectly safe during this time, things like that may be of concern to you, and so you may want to choose something that gives you better peace of mind during its use or maintenance.

Most Frequently Asked Questions

While this review may have answered a number of questions you have related to purchasing a dehumidifier, here are some additional ones that may help to answer any other questions you may have.

What is a dehumidifier?

The dehumidifier serves several purposes in the home and these can be used in a gun safe as well. When it is turned on, it will absorb most of the moisture in the air and release a nice and fragrances smell. The dehumidifier in the house can also be used as a method of improving your home smell and cleanliness and it will absorb all bad smell.

Gun safe dehumidifiers are different and they are not scented. They only absorbs the moisture to stop is from setting on your valuables and especially your rifles. You might not even notice the amount of moisture in the air, but I can assure you that there is moisture everywhere, it is only enhanced in coastal areas.

Why I should buy a gun safe dehumidifier?

A gun safe is the first step to keep your guns safe from burglars, but many people do not know that there is another silent killer that could cause immense damage to your firearms, especially if they are not used a lot.

Moisture is not all that common everywhere in the world, but it is really harmful in coastal areas and this is visible on a lot of the homes you see close to your favourite holiday destination. Moisture build up can also be present inside your home from the evaporation of water while cooking and close to the bathroom.

How can I monitor the humidity levels on my gun safe?

This can be done in a few different ways. First of all, there are measuring tools that you can purchase that will let you know what the level of humidity is in your gun safe. The obvious way to check is if you find that items are damp or that there are small droplets of condensation that are building up. The dehumidifier you purchased may also provide you with the measuring tool to let you know what the humidity level is at.

How can I reduce the humidity in my gun safe quickly?

Sadly, you may find that there is very little that you can do outside of purchasing a dehumidifier. Some safes will build up condensation in them no matter where you place them in your home. If you are a person who lives in a humid area, including living near lakes or rivers, you are going to have humidity build up. In this case, the only option you may have is to purchase yourself a dehumidifier.

What are the negative implications of not having a gun safe dehumidifier?

Not having a dehumidifier in your safe can be bad and rust will eventually start setting on the metal. If the gun is not regularly used and inspected, you might not even notice this and for people collecting military grade weapons like hand grenades, it can be life threatening.

The safety pins on hand grenades and firearms can easily take damage and over time, they will start to wear out and one day just breaks off. If you have a hand grenade collection, this could put your entire family and household at risk, but the dehumidifier will absorb all the moisture and ensure that it does not happen.

Why an external dehumidifier will not work?

With most gun safe brands improving the design to make it more resistant against water and fire, the dehumidifier will be great when it is built in. External dehumidifiers might not be the best and they will not be able to get to moisture on the inside of the safe. They might very well stop moisture from getting to the safe, but once the moisture is on the inside, it will still cause harm.

Internal safe dehumidifiers are also cheap and they can be easily installed. I like to consider this as a type of investment that will keep the guns and other metal objects dry and away from any moisture.

How can I keep my guns safe without a dehumidifier?

Actually, there are a few other methods to limit the moisture build up and the effect of the moisture, but these methods can be costly and thus the dehumidifier might be the cheapest option for you to consider.

Have your firearm plated. This can be expensive, depending on the type of metal you choose for plating the firearm, but it is also a trusted method of keeping rust from damaging your gun. Most guns are black in design and then they are plated to give them that silver look. I do recommend considering this as an alternative.

Make sure the safe is insulated. Adding more insulation to the safe is always great and it will keep the moisture from building up in the safe, but the insulation is usually done with silicone by normal people to save money. I recommend the special plastic for insulation and added fire protection, but it is expensive.

Regularly inspect your guns. This method might not be that expensive, but it certainly will take some time to do and you might need to brush up on the inner workings of your gun. But, by regularly cleaning the gun, you should be able to spot any problems and have them rectified.

These alternative methods can be used in place of gun safe dehumidifiers, but I do recommend that you do them in conjunction with a gun safe dehumidifier. People who cannot afford these more advanced options should definitely look into buying a gun safe dehumidifier at an affordable price.
