Humidity in the environment can sneak into your safe and slowly cause rust, corrosion, and even mildew on both the metallic and wooden components of your gun. While gun safes can resist high temperatures and force, they cannot keep your gun from dampness unless you use a dehumidifier. Yes, you need a dehumidifying unit in your safe. Is a Dehumidifier Necessary in a Gun Safe? On the other hand, if your safe’s humidity is high, we recommend that you invest both your time and money in purchasing an appropriate size of an electric dehumidifier. We recommend that you use the desiccant dehumidifiers if the humidity of your gun safe is low and you are only looking to maintain it.
These gun safe dehumidifiers vary in capacity and durability. Bigger safes require more capacity of the dehumidifier. When using desiccant dehumidifiers, you need to match capacity with the size of the gun safe. The gel inside the dehumidifier can absorb moisture or vapor for three to four weeks before you need to recharge them.
They are ideal options for safe owners who opt not to use electricity or those who do not want to drill holes in their safe walls.
