Most dehumidifier models are made of metal and they can easily rust and corrode if constantly exposed to moisture for a long period of time.  Your guns are also made out of metal so you will notice some rusts and chipped parts if they’re exposed to moisture.

  • Find a suitable spot where the contents and shooting gear isn’t in the way for good airflow between the firearms, the bottom of your safe and the top of it
  • Detach the power cord from the dehumidifying rod then lay the rod on the floor-bottom of the safe, towards the front side
  • Pass the power cord through the hole from the back of the safe and reattach it to the rod; you have to drill a hole if there isn’t one

How to Choose the Right Dehumidifier Model for you

You can choose between two types of dehumidifier models that are commonly used inside a safe.  One is the silica gel beads variety and the other is the rod models.  Both models serve the same safety purpose for your gun safe but operate slightly differently.  Whichever model you choose, it depends on your choice of what works best for you, your shooting gear, and your gun safe.

The silica gel models are the safest to handle, it would be a good choice.  You can place it anywhere safely in your gun safe.  This dehumidifier model can absorb any amount of moisture built up in the air and works similar to those small packets of silica gel found in shoe boxes for keeping out moisture.

The rod type dehumidifier is an electrical device that warms up the air in the gun safe.  It makes air inside the safe dryer and produces similar results of a silica gel gun safe dehumidifier but serves better in removing moisture and prevents damage.
