Buyer’s Guide

Why Do I Need a Gun Safe Dehumidifier?

A gun safe dehumidifier serves the purpose of controlling and reducing the moisture content inside the safe. By maintaining optimal humidity levels, you can prevent rust, mildew, and other moisture-related damage to your firearms. It is particularly vital in areas with high humidity or when storing firearms for extended periods.

Types of Gun Safe Dehumidifiers

Electric Dehumidifiers

These dehumidifiers use electricity to extract moisture from the air inside the gun safe. They typically have a heating element that warms the air, causing the moisture to condense and collect in a reservoir.

Electric dehumidifiers are known for their effectiveness in larger gun safes and continuous operation. Some models come with built-in humidity sensors that automatically turn on or off based on the humidity level inside the safe. They require a power outlet within or near the safe.

Desiccant Dehumidifiers

Desiccant dehumidifiers do not require electricity to operate. Instead, they utilize moisture-absorbing materials such as silica gel or calcium chloride to remove moisture from the air. These materials absorb the excess moisture, trapping it within the dehumidifier.

Desiccant dehumidifiers are popular for their portability and flexibility. They are suitable for smaller gun safes or situations where electricity is not available. However, desiccant materials need periodic regeneration or replacement to maintain their effectiveness.

Wireless Dehumidifiers

Wireless dehumidifiers, also known as battery-operated dehumidifiers, offer flexibility and convenience. They operate on batteries and do not require a power outlet, making them ideal for situations where electricity is not accessible.

Wireless dehumidifiers are commonly used in smaller gun safes or when portability is a priority. They are easy to install and provide effective moisture control. However, it’s important to consider the battery life and ensure that it meets your requirements.

Rod Dehumidifiers

Rod dehumidifiers are elongated heating elements that emit a low level of heat to keep the interior of the gun safe warm, thereby reducing humidity. These dehumidifiers are often installed at the bottom of the safe and are suitable for larger gun safes. They require a power outlet to operate and are known for their continuous and reliable moisture control.

Other Things to Consider When Choosing a Gun Safe Dehumidifier

Moisture Absorption Capacity

One of the most critical factors to consider is the moisture absorption capacity of the dehumidifier. It determines how much moisture the device can extract from the air within a given period.

The capacity should be sufficient to maintain humidity levels below the recommended threshold, typically below 50%. Consider the size of your gun safe, the climate in your area, and the number of firearms stored when determining the appropriate moisture absorption capacity.

Size and Dimensions

Ensure that the dehumidifier you choose fits comfortably within your gun safe without occupying excessive space or obstructing firearm storage. Measure the available space inside the safe and carefully review the dimensions of the dehumidifier before making a purchase.

Humidity Control and Monitoring

Some dehumidifiers offer built-in humidity sensors or hygrometers to monitor the humidity level inside the gun safe. These sensors can automatically activate or deactivate the dehumidifier to maintain a consistent humidity level.

This feature provides convenience and ensures that your firearms are protected even when you’re not actively monitoring the safe.

Durability and Construction

Since the dehumidifier will be placed in an enclosed environment, it is essential to choose a model that is durable and resistant to corrosion. Look for dehumidifiers made from high-quality materials, such as stainless steel or robust plastic. Read customer reviews and consider the reputation of the manufacturer to ensure the product’s longevity.

Noise Level

Consider the noise level of the dehumidifier, particularly if the gun safe is located in a living space or an area where noise can be disruptive. Look for models that mention noise reduction features or operate quietly, ensuring a peaceful environment.

Energy Efficiency

For electric dehumidifiers, energy efficiency is an important consideration. Look for models with an Energy Star rating or low power consumption to minimize electricity usage and keep operating costs down.

Additional Features and Accessories

Some dehumidifiers may come with extra features or accessories that enhance their functionality. These may include LED indicators, automatic shut-off, mounting brackets, or extension cords.

Evaluate these additional features and assess whether they align with your specific needs and preferences.


Should I put a dehumidifier in my gun safe?

Yes, you absolutely should put a dehumidifier in your gun safe to control moisture levels and prevent rust, corrosion, and other damage to your firearms.

What size dehumidifier do I need for my gun safe?

The size of the dehumidifier you need for your gun safe depends on the dimensions of your safe, the number of firearms stored, and the ambient humidity level. We recommend that you choose a dehumidifier with a moisture absorption capacity suitable for the size and contents of your specific gun safe.

What is the best thing to keep moisture out of a gun safe?

The best thing to keep moisture out of a gun safe is a dedicated gun safe dehumidifier. It effectively controls humidity levels, preventing moisture-related damage to firearms by reducing the risk of rust, corrosion, and other issues.
