Do Gun Safe Dehumidifiers Work?

If you have a gun safe, you will need a dehumidifier. It helps protect your weapons from rust and mold. So, for gun owners, owning a gun safe without a dehumidifier is very risky.

The million-dollar questions are; does a gun-safe dehumidifier work? How do they work? Up to what extent are they effective? Why put a dehumidifier in a gun safe? And what can you put in a gun safe to keep moisture out?

Yes, a gun-safe dehumidifier works!

The ultimate function of a gun-safe dehumidifier is to eliminate all moisture from the air inside the safe.

Gun Safe Dehumidifiers that Work

1) Silica Gel Desiccant

White Silica Gel Desiccant BeadsDesiccant is suitable for any enclosed space up to 3 cubic feet in size. A single tightly sealed pack of these will keep a 12x 12 x 12 (denote centimeter ) area dry for a month. It can be rejuvenated in the oven for 30 minutes at about 200 degrees to get the moisture out, and then it is ready to use again and again. Nothing drips out while placed upside down inside the safe. Ergo, a desiccant is highly effective for small-size gun storage.

2) Dehumidifier Rod

Lockdown Dehumidifier RodA dehumidifier rod operates by gradually raising and regulating the temperature within a gun safe. This allows the rod to control warm air and constantly flow inside the safe.

The rod comes in different sizes with specific watt ranges that are perfect for your particular needs. It is designed specifically for small enclosed spaces that do not have an element of active humidity, such as water from the fixture.

A dehumidifier rod comes with mounting brackets so you can quickly secure it to the bottom of the safe. And a separate plug adapter so you can cut the wire to the length you want before powering it up.

3) Portable Electric Dehumidifier

This type of dehumidifier has an 18-inch tank. It also features a light indicator that alerts you when the tank exceeds its total capacity and immediately shuts off until emptied. Today, it is the most efficient humidifier for controlling the moisture in a gun safe. (1)

How Do Dehumidifiers Work?

Humidifiers work by drawing warm air moisture into their coil via their fan. The warm air shrinks as it passes through the machine’s evaporation coils. Then condensation forms within the dehumidifier. (2)

Each time the condensation collects water droplets, it falls into the tank attached to the machine. Then colder water is emitted into space from the other side of the device.

The dehumidifier keeps the humidity in the air between 30 and 50 percent. If your dehumidifier has a humidity meter, you can adjust the humidity level to the desired percentage.


Gun owners can buy a gun safe and a dehumidifier. They are both excellent for your weapons and other valuables.

The gun safe is essential for safekeeping your ammunition. And the dehumidifier will effectively regulate the atmosphere inside the safe. Both are equally essential to keep your guns from corrosion and mists that cause dangerous malfunction.

There is a wide range of gun safe from which you can choose. So if picking the right gun safe is difficult for you, you can always seek expert advice here.
