EvaDry dehumidifiers contain unique crystals that absorb moisture and maintain humidity levels. They are available in different sizes and are renewable. When it’s time to change, the blue crystals will turn into pink and you will need to recharge the canister.
The desiccant dehumidifier also absorbs moisture. They’re generally small and cheap. Desiccant dehumidifiers are not great for long-term use. You also need a number of desiccant packs of them placed around the gun safe to increase effectiveness.
- Ultra high capacity desiccant/dehumidifier/dryer for gun safes.
- Enough drying capacity for even the largest gun safes.
- Easily rechargeable in a home convection oven.
Dehumidifier rods are designed to control the heat inside the gun safe. They can warm up the air. Dehumidifiers are tricky to use, and sometimes they can be faulty. They come in different lengths.
You have to match the length of the dehumidifier rod with the size of your gun safe. For example, you need to use a 12-inch rod for a 20 cubic feet gun safe.
- SPECS: 24 inches long with a 110-120 volt AC plug, 6 foot power cord to protect up to 300 cubic feet
- EASE OF USE: Rod features attachable legs for placement and a cord with a quick plug attachment to...
- SECURE: Protects your firearms all while fitting in the smaller, less usable areas of the safe
What Is a Safe Humidity Level for a Gun Safe?
The general safe humidity level for a gun safe is 50%. There are some places where if humidity levels rise above 50%, rust can form. Hence, it’s always great to check on your gun safe humidity from time to time when you have valuables inside.
How Long Does a Gun Safe Dehumidifier Last?
Some gun safe dehumidifiers can last for 10 years and even more. Most are disposable ones that are discarded after use. For example, a typical disposable desiccant dehumidifier can last up to a day of use. Afterward, it loses its effectiveness.
Keeping your gun safe at safe humidity levels will help protect what’s inside from rust and corrosion. While the contents of your gun safe are protected from thieves, you should also protect it from nature by installing a dehumidifier.
