Most gun safes do not allow air to escape or pass through. This significantly reduces air circulation inside. Some have ventilation, which allows free air circulation. Both situations can lead to increased humidity in the safe. Notably, high humidity levels lead to moisture. Being metallic, guns are prone to rusting when exposed to moisture. This can seriously affect your gun. Besides, it can lead to the growth of mold and mildew on felt linings, leather holsters and other related materials. Places with fluctuating temperatures make it hard to control humidity. However, you should note that humidity can be anywhere regardless of the temperature. A good gun safe dehumidifier can help you get rid of humidity problems. This will make your gun safe from related effects. In this article, we have listed the best dehumidifier for gun safe and other dehumidifiers you can consider for gun safe moisture control.

Do you need a dehumidifier in a gun safe?

Everyone needs a dehumidifier for their gun safe. It does not matter where you live, humidity can slowly increase and damage your firearms.  When you lock up your safe, it prevents the air from flowing. This means the moisture trapped inside your safe will condense onto your valuables. Condensation may be in form of water droplets that can cause chemical reactions like rusting of your gun. In other scenarios, it can lead to the growth of mold in the safe. This makes a dehumidifier a vital component for your safe. 

Do dehumidifiers work in gun safe?

Yes, dehumidifiers work in gun safes. This is because gun safes can also harbor moisture. Dehumidifiers work by removing water molecules from air. This helps prevent condensation. Dehumidifiers come in all sizes small and big. So, you can lock it in your safe of any size and get rid of all moisture related issues. 

How can I choose a dehumidifier for my gun safe?

  • Size

The size of any dehumidifier you choose to put in your gun safe should be small enough. It should not be big to compete for space with your firearms.

  • Recharge duration

If your device does not operate while charging, you would not want one that takes the whole day recharging. Your dehumidifier should not take more than 15 hours trying to recharge. This is because you want to be able to quickly get the dehumidifier back into your safe. Otherwise, your safe will be left unprotected from moisture. 

  • Type of gun safe

The type of your gun safe will guide you on the dehumidifier to choose. Some gun safes are airtight while others have ventilation. When your safe is airtight you need desiccant dehumidifiers. However, when your safe has ventilation, you could opt for electric dehumidifiers. Desiccant dehumidifiers contain silica-gel or other absorbing material. Electric dehumidifiers work by pulling water molecules from the air into its coil via a fan. When the molecules are exposed to the coils, they start to condense. The condensed droplets will then drip into the water tank. After which, the warm air will be pushed back into the air for circulation.  But, you should note that both types can effectively perform  in all sorts of gun safe

How do gun safe dehumidifiers work?

Gun safe dehumidifiers work by removing water from the air in the safe. This can be done in two ways. One is through air heating and another is absorption. These approaches depend on the type of dehumidifier you have. 

How to install a gun safe dehumidifier

First you need to check the instruction manual of the dehumidifier. This will give you a guide on how to fix the device inside the gun safe. After that you may follow the steps below to install a rod dehumidifier.

  • Place the dehumidifier horizontally in your preferred position.
  • Most gun safes have a pre-drilled hole for wires. You can run through an electrical cord going outside.
  • Mount the rod with clips
  •  Turn the rod or dehumidifier on

Where should a dehumidifier be placed in a gun safe?

It depends on the type of dehumidifier you have. When using an electric dehumidifier, the lower part in the safe is better. This will allow the power cord to connect to the supply. If you use a desiccant dehumidifier, you can place it anywhere in the safe. 

What can you put in a gun safe to keep moisture out?

A dehumidifier would be the best option to keep moisture out of your gun safe. This works by removing water molecules in the air. 

How to recharge gun safe dehumidifiers?

When using a desiccant dehumidifier you can recharge by drying the silica gel. You can put the silica gel in the oven or microwave for some time as indicated by the manufacturer. For electric dehumidifiers, you need to connect the rod to the power supply for a given period of time. 

What size dehumidifier do I need for my gun safe?  

This heavily depends on the type of dehumidifier you have. There are two types of gun-safe dehumidifiers. These include electric and desiccant dehumidifiers.  These differ in terms of size and occupation.  Giving you an example of an electric dehumidifier. A 12 inch dehumidifier covers 100 cubic feet. That of 24 inches can cover 300 cubic feet of your safe. So, you can calculate and determine what fits in your safe. But, when using a descant, size is not a big issue. You only have to understand their capacity. Desiccant dehumidifiers usually come in small sizes.
