How to Buy the Best Dehumidifier for Gun Safe 

How to Buy the Best Dehumidifier for Gun Safe

Photo: Lockdown

1. Dehumidifier Type: Electric or Desiccant (Silica Gel)

As you pick up the best gun safe dehumidifier, you will first need to decide the types that you want. And here the two main choices are electric and desiccant. Each of these dehumidifiers has its pros and cons, and will hence work for different users and situations.

Electric

Electric dehumidifier for gun safe will use an exposed heating element that will produce heat to evaporate the moisture in the safe. These are more efficient dehumidifiers than the desiccant types, which explains the increase in their popularity over the years.

The high efficiency of these dehumidifiers makes them ideal for those that live in high humidity areas. However, these types will require you to have an outlet near the safe, and you may have to drill a hole on the safe for the cable.

Desiccant (Silica Gel)

The desiccant dehumidifiers for gun safe will utilize silica gel beads to absorb the excess moisture. Unlike the electric types, the silica gel can only absorb a specific amount of moisture before you have to recharge.

With these silica gel packs, you will not need to drill holes on your safe, and neither will you need to have a power outlet close to the safe. These are the easiest dehumidifier to install as you will only need to place them inside the safe.

2. Absorption Capacity

The absorption capacity should be one of your primary concerns when choosing a dehumidifier for your gun safe. And this is because it will determine how much moisture the unit can absorb and hence its effectiveness.

Electric and desiccant models will have different absorption capacities. For the electric models, it will depend on how powerful the unit will be, while the desiccant types, the absorption capacity is highly dependent on the quantity of the silica gel. The more the silica gel, the higher the absorption capacity.

The exact absorption capacity that you will need depends on factors like the humidity level in your area and safe size. However, large absorption capacity is always preferable.

3. Size and Coverage

Dehumidifiers for gun safe will also differ in their size and coverage. And to make sure what you buy works well for you, it is vital to make sure it is large enough to cover your specific safe size.

The coverage area for these dehumidifiers is measured in cubic feet, and you can get something with as little as 30 cubic feet coverage to as large as 500 cubic feet and even larger.

For smaller safe sizes, something with a 33 to 57 cubic feet coverage like the Lockdown 222178 should be good enough.

4. Longevity

Longevity is also a key factor to consider when shopping for the best dehumidifier for gun safe as it will ensure you get value for your money.

For the electric models, you will hardly ever have to worry about longevity because, with proper maintenance, they can last almost infinitely.

However, if you are buying the desiccant types, you need to make sure the model you buy will provide a long service life before requiring recharging. A 20 to 30 days service life before recharging like what you get on the Eva-Dry E-333 should be good enough.

5. Safety

You will also need to make sure that the dehumidifier for gun safe you choose is safe to use, and this is more so when buying the electric types.

For the electric dehumidifier, you need to make sure that the unit is safe to handle and with no naked wires or cables that might pose safety risks. Also, auto shut off function that prevents overheating will be very useful for ensuring extra safety.

The material used to make the dehumidifier will also determine its level of safety. Here you need to make sure that the models you choose will not have any toxic materials.

6. Installation

Some gun safe dehumidifiers will be easier to install than others, and so you need to keep the ease of installation in mind when choosing one.

The silica gel or desiccant dehumidifiers are the easiest to install as all you will need to do is throw it into the safe.

Electric dehumidifiers need an electricity source and will sometimes require you to drill holes on your safe, which makes them more hectic to install. But, if the safe has pre-drilled anchorage holes, installing the electric dehumidifier should be easy for you as you will not need to drill more holes.

Conclusion 

With the best dehumidifier for gun safe, you will have a reliable tool that will help protect your firearms from the damages that come with excess humidity.

There is a model for everyone on our list. But, the Lockdown 725721 is our best overall option thanks to the versatile size options and the low-profile design.

However, if you prefer the desiccant types and are also looking to spend less cash, the more-affordable Lockdown 222178 should serve you well.
