The 7 Best Gun Safe Dehumidifiers

Gun Safety


People can invest hundreds of dollars into the best and most secure safe to keep their firearms protected, but what everyone forgets is that their firearms are not truly safe from environmental threats.

Metal tends to rust and corrode when exposed to moisture for long periods of time and, while your safe can protect a gun from theft, kids, and potentially even fires, it cannot save your weapon from the humidity.

Prolonged exposure to moisture in the air can leave you with a musty, mouldy gun safe and corroded or rusting guns. Sadly, few people seem to think to stop the moisture before it has destroyed the contents of their safe. That is why having the best gun safe dehumidifier is a must — especially if you live in a humid area.

Why do I need the best safe dehumidifier?

As we all know, prolonged exposure to moisture, such as humidity, can cause paper documents to mould, cause the metal to rust or corrode, and cause unwanted smells to arise.

This can and will happen in your safe if you don’t protect it. Keeping your safe truly safe starts with keeping the atmosphere from breaking it down. Humidity is a silent enemy that will cause your safe and firearms to rust and corrode.

However, owning the best safe dehumidifier can prevent this. The best dehumidifiers for safes will eliminate or prevent the moisture from permeating its immediate surroundings and keep your safe completely moisture-free. This will keep your valuables and firearms safe.

Best Gun Safe Dehumidifier

Excess of everything is bad. Same applies to your Gun safe while you are checking the level of humidity in it. If the humidity is between 45% and 50%, it is an ideal humidity level.

Below to this level will make your guns and ammunition dry. Similarly, the above level of humidity will make your guns and magazines rusty. A responsible gun owner always checks the level of humidity particularly in rainy seasons when it increases generally.

Effects of Humidity on Guns

  • Since the bullets and shells have powder, excessive humidity plays havoc for them. The bullets and shells are tightly sealed, but you cannot confirm whether they are airtight. So, the humidity makes them useless when you want to use them.
  • Sometimes, the humidity in the gun safe is absorbed by the powder in bullets and shells. It denatures the oxidant particles of the powder. As a result, the ammunition powder ignites unevenly. It can be even more dangerous when the reaction is delayed.
  • Humidity can destroy your guns completely. It does not matter which type of weapon you are using. Every gun is made of metal and the humidity can make its moving parts rusty. Some parts can swell up and some will be rusty. As a result, you cannot fire the bullets through it properly.
  • The moderate moisture level is good for your guns and other weapons. If you hold some guns and rifles with wooden handles and woodwork on them, you must be very careful about the right level of moisture. If you keep the wooden components dry, there can be a breakdown in them. So, you need to keep the gun safe a bit moist to avoid this breakdown.
  • In such a situation, a high-quality Dehumidifier is required to keep the moisture in the gun safe at a balanced level.

Buying Guide

best gun safe dehumidifier

There are some very important factors you need to consider before you select the best safe dehumidifier. You need to keep some key principles in mind. See below to know what they are.

Size & Coverage

Gun Safe Dehumidifiers come in different sizes and designs. The designs are according to the moist area they cover. So, you need to check the coverage area first. It should cover the entire gun safe if you use it.

That’s why check the size of your gun safe and see whether your desired dehumidifier covers that much area or not. Generally, electric dehumidifiers are considered more effective. They can end up the moisture up to 100 cubic feet. If you have a smaller gun safe, you can select a smaller product. For a bigger gun safe, an electric dehumidifier is perfect.

Easy to Install

It should be easy to install. If it is not user-friendly, you may not install it correctly. As a result, it may not work to your satisfaction. If you are looking for a moderate gun safe, Silica Gel dehumidifiers are the best for it. These are easy to install and there is no extra toil needed for the installation of such dehumidifiers.

You need to put such dehumidifier inside the gun safe and that’s it. They will work on their own now. On the contrary, you need to use a power source to use the electric dehumidifier. It can be a bit complicated for you to install it.

Some gun safes already have drilled holes for such devices. If your gun safe holds a pre-drilled hole, the installation of electric dehumidifier may be easier for you. Otherwise, you need to be very careful.

Absorption Capacity

Another factor you need to check is the absorption capacity of the dehumidifier. If you have selected a silica gel product, you need to check the number of beads in it. Actually, these beads absorb the excessive quantity of moisture from the atmosphere. So, always select a silica gel product with a large number of beads.

It comes with high absorption capacity. The absorption capacity also depends on the number of guns you have put in the safe. If your guns have lots of woodwork and you have many guns, you need to use a highly absorbent dehumidifier. If you have a few guns, you can use an average absorbent dehumidifier.

Easy to Use

Last but not least is that it should be free from complicated features. It should be easy to use. If you are well-informed on how to maintain it, you will be comfortable while using it. So, make sure, the model you are selecting is easy to use and simple to maintain. It is necessary for durability and longer life.

Major Types of Safe Dehumidifiers

Generally, the best dehumidifier for safes come in one of two forms: electric or renewable. Each of these types has benefits, each providing good options for different people and situations. Let’s take a look at the differences, so you can consider which is best for your particular needs, either.

Electric dehumidifiers

PEET dehumidifier

These are the popular option and are highly effective in gun safes especially. Electric dehumidifiers remove moisture from the air by heating the surrounding environment, instantly evaporating any moisture trying to invade your safe.

They usually come in a sleek rod shape that is an exposed heating element. However, these dehumidifiers do require cords and need to be constantly connected to a power source. This means that your safety must be able to accommodate an electrical cord.

That can be a definite deal-breaker for some safes, especially if your safe does not have a hole for wires. But do not fret yet… for you, the best dehumidifier for your safe could be a renewable dehumidifier.


  • Instant evaporation
  • Controls moisture
  • Sleek


  • Must be plugged in at all times
  • Wires
  • Slightly more expensive option

Renewable dehumidifiers

Stack-On dehumidifier

Renewable dehumidifiers tend to be more compact dehumidifiers that work for small areas such as gun safes. They do not rely on any power to work. In fact, they usually utilize special minerals that absorb the moisture from the air and do not need anything to help it work at all.

Most of these will last a good 20 to 30 days before they need to be renewed as well, and the renewal process is usually time in the oven to dry it out (although some do need to be plugged in for a while to dry out).

Renewable dehumidifiers are completely eco-friendly. This is a great option for someone who does not have a plug near their safe or does not want to run wires and cords in and out of their safe.


  • Eco-friendly
  • No wires
  • Renewable
  • Small


  • Has to be renewed every month
  • Not electric
  • Not dehumidifying while renewing
