Best Dehumidifier for Gun Safe | 5 Best of the 4 Types


Gun safes are airtight which reduces air circulation and can cause the humidity in the safe to rise.  Metal items such as guns are prone to rusting and corrosion when exposed to moisture when the humidity is high. This can lead to serious damage to your gun, or cause undesirable mold and mildew to develop on leather holsters, felt linings and the like. If your safe is in a garage it is particularly difficult to control the humidity in the safe because of fluctuating temperature.  But a good gun safe dehumidifier can solve most humidity problems.

The best way to control the humidity in a gun safe is with a dehumidifier.  These devices absorb moisture from the environment or raise the temperature to lower the humidity, which keeps items safe from corrosion and rusting. Some of them work by drying the air inside the safe gun while others use silica gel (a desiccant) to absorb moisture.
