Keeping Your Guns Dry and Rust FREE!
A good gun safe dehumidifier is a must if you live in a moist climate. When you close the safe door, the moisture in the trapped air has nowhere to go and can easily be transferred to your guns. The resulting water on the gun can cause them to rust.
There are many different dehumidifier choices. Personally, I prefer an electronic option, although there are many fine desiccant models as well.
Choosing a Dehumidifier
The key to choosing any dehumidifier is determining how much space it can actually clear of moisture. Most dehumidifiers will tell you they will work in the size of the safe (e.g., a safe up to 30 inches wide)or they will state it will dehumidify up to a certain cubic foot area (e.g., 100 cubic feet).
If you have a larger safe, you may have to buy more than one dehumidifier, especially if you go the desiccant route, as these models tend to clear a smaller area of moisture.
Electric Gun Safe Dehumidifier
Regardless of which electric model you choose, if your safe does not have an outlet in it, you will have to drill a hole in the safe wall. Make sure the dehumidifier you are using allows you to unplug the electric cord so that the cord can pass through the drilled hole. The last thing you want is to drill a hole the size an electric plug.
This model is 18 inches long and works in gun safes 30 inches wide and wider. This model retails for about $40.
This model is the latest and greatest from Browning. It actually can be bent to conform to tight spaces. There
is no recommended size limit. The cord does disengage to allow it to easily slip through a drilled hole if
needed. Retails for about the same price as the rod versus, $40.
The two Lockdown gun safe dehumidifiers are a good inexpensive option. The 12 inch models removes moisture up to 100
cubic feet, while the 18 inch model will do up to 200 cubic feet. On both models, the cord is removable to allow it
to more easily fit through a drilled hole. Pricing ranges from $20-$25 dollars depending upon the model size.
Arguably, the highest quality (and UL tested) is the Cannon GunSaver. It will dehumidify up to 100 cubic feet. It
is a bit pricey, approximately $72, but it really moves the air around your safe to keep things nice and dry.
This model has a little bigger circumference but is a very efficient model that can dehumidify up to 100 cubic feet.
The cord is removable, for easy pass through, and only retails for about $28.
Desiccant or Non Electric Gun safe Dehumidifier
|Eva-Dry E-333||Eva-Dry E-500|
These models are some of the most popular, non-electric, dehumidifiers in the industry. The E-333 does up to a 333 cubic foot area, which should be more than adequate. The E-500 does up to 500 cubic feet.
Both units take about 30-60 days to “fill up” with moisture. Then, you will have to plug the unit into an outlet so it can dry itself. This process will take a bout 10-145 hours. Cost range from $15-$28.
This desiccant model is simply a box that absorbs moisture. It works in safes up to 30 inches wide (approximately 37cubic feet). Once the desiccant material is saturated, you will need to “recharge” the material by drying it in an oven.
