More Information

Choosing the right one is based on two decisions, the first is subjective, the second is objective. The objective decision is based on a power source, do your safe have access to a power source to operate the dehumidifier? If not, move on to the desiccant, choice issue solved.

Now to the subjective option, what do you prefer? An electric or chemical dehumidifier? It’s all down to preference. The desiccant dehumidifier requires an occasional refill of silicone balls or re-drying the silica gel, other than that the decision will have to factor in the safe size, which is the internal dimensions for storage.

The safes dimensions will determine whether the item you choose will provide maximum efficiency, or not.

To make life easy for you, we already tested just about every option available on the market, and here are the two different dehydrators. We provide any standout features, two or three pros to why the item is in the list and of course our review.

This guide will be split into two sections; desiccant dehumidifiers and electric dehumidifiers.

Conclusions

One of the biggest issues facing any gun enthusiast or gun owner is how to protect their weapon from corrosion when not in use. All gun owners will have one kind of safe, either small personal one or a larger one that also supports documents as well as multiple guns and rifles.

No matter where you live, a closed space will become moist over time, and if you live in hot humid states or cold, wet states, you will need really good gun protection. This review comes after testing an checking hundreds of options.

Gun Safe Dehumidifiers

Types

Electric Safe Dehumidifiers

The electric safe dehumidifier is extremely efficient in reducing the humidity level in any closed space. They operate by heating up the enclosure 24/7.  While they are very efficient at perfuming their job, they do have three downsides:

  1. They heat up and can be too hot to touch
  2. They use electricity, even a small amount adds to your bill
  3. They must be placed away from flammable objects (paper etc.)

Silica Gel Dehumidifiers

These are exceptionally easy to install but have a higher maintenance requirement than electric models. The silica gel bead works by sucking out the water molecules in the air, trapping them in the bead. This means that once the bead is full, it will not suck in anymore and this is the time you need to replace or recharge the beads. Recharging is done by drying the beads out with heat.

There are two versions for recharging silica gel units, the electric and the oven heated. The electric versions have a small heating element in the body, and you attach the body to an AC outlet, this dries the beads over an 8-12-hour period. The oven heated units require you to place them in an oven, or just the beads in the oven and heat for 2-3 hours or until the beads are dry.

 

Key Performance Indicators (KPI’s)

When buying a gun safe dehumidifier, there are a number of KPI’s to look out for in each model type.

Absorption Capacity

This is a silica gel KPI. You need to check how much water moisture the beads can absorb before requiring recharging or changing. This is done by reading the manufacturing details. Take into account the larger the unit, the more sucking power you get. So, this means that size does matter since the materials used by all the suppliers are basically the same. Until someone discovers a new gel formula, all the bags will be variants in size and shape of the basic material; silica gel.

Size and Coverage

As mentioned, size does matter with silica gel models. The same is true for electric units too since they cannot heat up over a certain temperature or they will constitute a fire danger as well as a destructive force.

This leads you to factor in the following equation size/coverage=coefficient of power (Efficiency). Where the size of the actual unit and the area the manufacturer recommends, it will cover (such as 100 cubic feet). The smaller the efficiency number, the higher the power ratio.

This method works with all models, you simply take the overall size of the unit which is basic geometry (DxL for the round, and LxWxH for rectangular) and you get your size, now what does the manufacturer state the coverage is, and presto you have your coefficient of power.

Ease of Installation

In most cases you just check the dehumidifier unit into the safe and walk away. However, this works only with cilia gel units. For electric units, you need to factor in a number of considerations.

You will need a pre-drilled hole for passing the power cord through or use the anchorage hole. This requires you remove the plug and pass the bare wires through, and then reattach the plug.

You will need a long enough unit cord to reach the outside and either directly connect to an AC outlet, or to an extension cord.

If you need to drill a hole you will need to consult with the Safe manufacturers manual or customer service to know where to drill the hole for best performance; you don’t want to compromise your safe’s security devices for a heating unit.

Some units come with brackets which you might consider installing in larger safes for better protection. Also, consider where you place the heating elements, so they do not come near any flammable objects.

Ease of Use

There is no difference between these models; they are both easy to use once they are installed. The electric once requires you turn them on, and the silica gel just require you look at the indicator port once a week.

Price

The price is another equation that is a product of the coreference of power, which is Price/CoP=Value for money. You take the confidence of power number you obtained when checking the efficiency of the unit’s performance, and you divide this into the price. The closer the value is to zero, the more cost-effective this unit is.

Other Factors

Check Their Coverage

Make sure that the dehumidifier coverage is larger than your safes internal storage capacity. You do not want to buy a unit that covers less area than you have in your safe. At the same time, do not buy a unit that exceeds your safes storage capacity by more than double. This means, don’t buy a 33 cubic foot unit for a 90 cubic foot safe. Get the 100 cubic foot unit to cover areas between 60 to 100 feet, and over 100 feet jump to the next level.

Evaluate Your Guns

Always check your guns on a regular basis, and when the heating elements are involved, you should consider waxing the wooden stocks and parts, since dried out wood will crack. Also, check for mildew and moss on all the surfaces of the safe and your guns. It is always prudent to be extra careful with your weapons.

Check Their Maintenance Requirements

When buying a dehumidifier, consider the price and functionality. The more expensive and larger the unit, the more maintenance you will need to consider.

The 3 Benefits of a Gun Dehumidifier

Now we get to why you need a gun safe dehumidifier. There are three basic benefits, and they will improve your living standards.

Keeping Your Ammunition Dry

The number one cause for ammunition degrade is humidity. Add to this that all ammo has a shelf life, and you need to contemplate leaving your ammo lying around unprotected. A dry, protected environment will make sure your ammo lasts well into its shelf life and maybe even longer.

Take into a stock that humidity degrades your ammo immediately, but it does accumulate over time, and eventually, you will get degraded ammo that is not accurate and in some instances totally ineffective.

Just consider that if you use a weapon for security issues, law enforcement or hunting, you don’t want to be in that situation where you have a misfire due to bad ammo.

Keeping Mold Out of The Safe

Many gun safes are used for more than just guns, and this raises the issue of mold. Let’s start with the basic ammo boxes made of cardboard, then move onto documents such as money and passports. The next step is the wooden gun parts. The last thing you want to see on any part of your safe are those telltale signs of spores accumulating.

Moisture will lead to spore growth which will accumulate into the mold, and the next time you open your safe you have a whole ecosystem protected by the EPA.

Add a dehumidifier immediately and stop any chances of mold accumulation.

Protecting Your Safe and guns from Rust

The final and maybe most important aspect for all gun owners is rust. The big R. You do not want to wake up with a rusty barrel, rusty parts, or anything to do with oxidization. Once rust sets in, the part has to be replaced. There is no other way around it. If you want an efficient weapon, it has to be in perfect condition. Just as you wouldn’t expect a 5’5” x 400lb man with clogged arteries to run a marathon, don’t expect your gun to perform well when rusty.
