Types Of Dehumidifiers

There are 3 types of dehumidifiers available in the market. But only 2 are used mainly for a gun safe to keep away any rust or corrosion. 

Best Dehumidifier For Gun Safe

  • Electric Rod

Electric rode dehumidifiers are used widely for removing any moisture, mold, dew, or corrosion, etc., inside the gun safe. The rod heats up through electrical power and warms the inside air keeping the inside temperature warm from the outside temperature eliminating any moisture.

The electric rod will surely keep your guns completely dry and works very silently. Also, you don’t have to recharge again and again to use it. An electrical power outlet is needed to operate.

Dehumidifier Type

Always keep in mind selecting the type of dehumidifier according to your safe. Always check your gun unit size and easy setup. If your gun safe is big and has a hole inside for electric wire can pass, then go for an electric rod that can easily eliminate moisture in a large size gun safe. 

And if the safe is small and does not have holes, then go with the silica-based unit, easily covering the safety box and easy to recharge.


Look at product features and coverage of the dehumidifier you will purchase because each unit has some cubic foot limitation. Minimum cubic feet start from 100 cubic feet (18″) and last up to 500 cubic feet (36″) for bigger safe.


Of course, go with the dehumidifier, which has a small size, or it should not takes extra space. The best unit will be which removes moisture fully and remain unnoticed in the safe.


If you want a dehumidifier that works for many years and does not require constant charging, always go for an electric rod. And if you are looking for a dehumidifier that works without electrical power consumption, then go for a Desiccant dehumidifier.

Evaluate Your Stored Firearms

Always have a look at your stored firearms inside the gun safe. Old guns are affected more by moisture than any other handguns or rifles.

If you have stored any antique or old guns prone to damage by more moisture, then investing in quality and the expensive dehumidifier will be worth it.


Dehumidifiers are generally low in price, especially Desiccant types in comparison to electrical ones. But I would say it all depend on your budget which type of unit you can buy.
