Best Gun Safe Dehumidifiers

Last Updated: January 6th, 2021 | By Peter Robinson

Gun safe dehumidifiers are a must have for firearm owners. They are particularly essential in protecting your gun safe from moisture and dampness, which can cause rust and corrosion and eventually damage the gun. While a gun safe is necessary for keeping your gun away from unauthorized users, physical damage, and potential gun abuse, a dehumidifier is essential in keeping both the safe and gun in perfect condition. Just like its name, a dehumidifier for gun safe is a device that works to expel moisture from the air. Yes! moisture exists in the air. 

Generally, gun vaults are not airtight when locked, which means moisture can easily be trapped inside the safe; this makes the safe prone to mold, mildew, rust, and corrosion. The best gun dehumidifiers will prevent this and keep your gun in good condition for a long period of time.

You might ask yourself, what damage can too much humidity cause?

Part of the reason for getting a safe in the first place is to keep your valuables in the best condition for a longer period of time. This means they are either very delicate, expensive, or important. Whether they be documents, jewelry, or guns, etc. You don’t want to go back to your safe and find your valuables ruined beyond repair. It will break your heart no matter how strong you are. Too much humidity in your safe can wreak this sort of havoc in the way of rust and corrosion. 

When your safe is faced with too much humidity;

  1. It becomes a breeding ground for mildew. No matter where you live, your vaults are prone to dampness as air contains moisture. 
  2. It can reduce the effectiveness or quality of your arms.
  3. It can lead to rust, which will over time damage the safe.

You can never be too cautious when handling a vault; no matter how hard you try, a significant amount of air rushes inside your safe and is trapped inside whenever the vault is opened. That tiny air can do a whole lot of damage if it is not properly checked; the air eventually metamorphoses into "too much humidity" that is capable of destroying whatever you have kept in your safe. This is why a dehumidifier for gun safe is a must-have.

Advantages of a Gun Humidifier

Gun owners prefer the use of a dehumidifier for their gun safes because it's;

Easy to Install and Use:
The usage and installation of dehumidifiers are quite easy. With the electric dehumidifier as in rod models, just plug it into a power source or use batteries, while the desiccant dehumidifier as in Silica gel is to be placed inside your gun safe and make sure you recharge now and then. However, we recommend you study the manufacturer's guide carefully before usage.

Easy to Carry:
Dehumidifiers are portable (if needed) and can be easily carried from one place to the other without stress. You do not need to worry about moving it when traveling to another city.

Perfect Solution:
A dehumidifier is specifically designed for the gun safe; it has a high capacity of absorption and can not be compared with other methods of lowering humidity. Thus making it the best solution for controlling humidity level in the safe.

Most dehumidifiers are quite affordable, and even the few that are highly-priced are well worth it.

Doesn't Occupy Much Space:
Dehumidifiers occupy only a little space in the gun safes. You do not have to worry about it taking too much space in your vault.

These, amongst others, are some of the advantages of getting a dehumidifier for gun safe. With the increase in demand for gun safe dehumidifiers, you can tell for sure that its relevance of dehumidifiers for gun safe can not be overemphasized. Today, different varieties of gun safe humidifiers are available in the market, thus making it difficult to choose. This article will guide you on some of the best gun safe dehumidifiers and what you need to know before purchasing.

Benefits of Owning a Gun Safe Dehumidifier

Reduces Condensation and the Growth of Mildew:
A gun safe dehumidifier will hinder the increase in moisture and mold. Dampness is the major cause of mold growth in a safe. A dehumidifier ensures that the safe is completely dry to prevent any sort of mold growth or condensation.

Prevents Damage to Guns:
A gun safe dehumidifier helps to prevent your gun from complete damage caused by moisture. Since most guns are metallic in nature,, they are highly prone to rust when they contact water.

Keeps the Gun in Proper Condition:
A gun safe dehumidifier helps to keep your gun functioning well for a longer period of time. A little decay or rust can negatively influence the effectiveness of a gun.

Eliminates Odors:
The growth of mildew in your safe could cause decay and pollute the entire safe. The best dehumidifier will keep the safe air dry by soaking up surplus moisture in the air.

Types of Gun Vault Dehumidifiers

The different types of gun safe dehumidifiers are categorized into two. They are the rod models (the electric gun safe dehumidifier) and silica gel (desiccant gun safe dehumidifier).

Silica Gel (Desiccant Gun Safe Humidifier):
For those who are no comfortable with drilling holes on vaults, this is the best option to go for. A desiccant is any substance that absorbs water, such as silica gel. The silica gel dehumidifier, when placed inside the safe, sucks up excess moisture in the gun safe, thereby lowering humidity. You can always monitor the beads by observing the color; once it changes from its original color, it is time to take out and replace. The silica gel gun safe dehumidifiers are safe to use and the most commonly used dehumidifier for gun safe among gun-safe owners.

Rod Models (Electronic Gun Safe Humidifier):
Most people consider the electronic unit the best gun safe dehumidifier because it is simple to use. They usually take the form of a dry rod, and when plugged, the dry rod emits warmth, which engulfs the vault and dries out trapped moisture.

The dehumidifier rod models are electronic units that require a power source or batteries. When plugged in, the heated rod releases warm air into the atmosphere and gradually circulates all around the safe. The heated air dries up moisture from the safe, thereby preventing the build-up of mold, and condensation, leading to damage of guns. Hole drilling is compulsory with this electric dehumidifier.

What Does Humidity Do To Your Gun?

The right amount of humidity level in your gun safe will not cause any harm to your gun, but too much humidity can damage your guns if proper care is not taken. While it is important to reduce excess humidity from the safe, it is important to note that too low humidity can over-dry your gun's wooden component and cause it to break. This is why it is advisable to keep the humidity in your gun safe, not too high and not too low.

Now the question is, what is the right humidity level for your gun safe?

The standard humidity level for your gun safe is 50% at room temperature (about 70 degrees).

You can always use a hydrometer to monitor your gun safe humidity level to ensure that it is on the required 50% relative humidity.

What Else Can Be Done To Keep Humidity Levels Low?

Although dehumidifiers are one of the greatest ways to keep humidity levels low, there are other effective ways of protecting your gun vault.

You can keep humidity levels low by:

  • Placing silica gel in your gun safes: This moisture absorbing material is the same small packaged substance you find in your new pair of shoes with the warning “do not eat.” The silica gel is what is used in a desiccant dehumidifier, and they act as an absorbing agent.
  • Substituting with light bulbs (not recommended): Just like the rod units, a light bulb, when heated, releases warm air and can prevent condensation
  • Placing the gun safes in a cool, dry place. The gun safe is best kept in an area free from humidity or too much heat.
  • Oiling the gun regularly: Frequent application of oil on the gun will go a long way in protecting it from rusting.
  • Placing desiccants in the safe: You can use other forms of desiccant substance like charcoal, dry rice, or baking soda in an open bowl in the safe. This method requires you to continuously replace after some time and is not a suitable permanent solution for regulating humidity level.
  • Constantly cleaning your gun: Much like keeping a well lubed gun, consistently cleaning your gun will help you track the irregularities on your gun or safe before it gets out of hand.
