Types of Gun Safe Dehumidifiers

Gun safe dehumidifiers come in two different forms: electric and desiccant. So what’s the difference between the two?

Electric dehumidifiers work by heating up and circulating the airflow inside the confined space to draw the moisture out. This method is excellent at preventing a condensation buildup on the inside of the safe, keeping all your valuables and guns dry. Most experienced users recommend placing the humidifier at the bottom due to its tendency to heat up the interior of the safe. As the hotter air reaches the top, the dehumidifier should already start to cool down. Then the cooler air goes back again at the bottom. The cycle continues in order to maintain the temperature inside the safe, hence keeping your guns safe from rust and mold.

Unlike dessicants, the electric versions are more convenient to use. These options are more reliable and can absorb more moisture compared to the desiccant models. The only downside of this product is that you will need to drill holes in the safe for the power cords IF they don’t have them already. Many safes already will.

How Gun Safe Dehumidifiers Work

Too much humidity in the air can destroy any objects made of metal, including your precious guns. Rust, corrosion, and mildew can all be harmful to your valuables without proper protection and maintenance. That is why gun safe dehumidifiers become important tools to handle these situations effectively.

1. Dehumidifiers can help reduce rust

Seeing rust and corrosion taking over your expensive weapons is a nightmare. Your gun safe, since it is made of metal, may also fall victim to this natural chemical reaction. 

To prevent costly repairs and irreversible damage, gun safe dehumidifiers can help you control moisture, a necessary ingredient for the reaction and protect your valuables for a longer time.

2. Dehumidifiers can prevent molds and mildew

With a gun safe dehumidifier, it is easier to prevent molds and mildew from forming inside your safe. Keep in mind that these spores thrive well in a damp or moist environment. So, it’s essential to keep the inside of your gun safe clean and dry.

How We Choose and Must-Have Features

Looking for the best gun safe dehumidifier can be overwhelming if you have no idea what product suits your needs. Here are some factors you can think about when you shop:

Size

Gun safe dehumidifiers can come in different shapes and sizes. If you have a larger room for your gun collections, then you might need a product that is designed for larger cabinets. If you have a smaller gun safe, then it is best to choose the one that fits well in tight spaces.

Capacity

Another feature you need to consider is the amount of space the dehumidifier can cover. So how do you know if it is the right one for you? Simply check the product details - look for the internal width, depth, and height and multiply these to get the covered area in cubic feet. This will help you approximate if the device can cover the entire volume of your gun safe.

Maintenance

Dehumidifiers can come in different types, requiring different maintenance. Some products need to be heated in the oven to remove the accumulated moisture while other devices might need to be plugged into an outlet to reactivate them. Choose the one that is more convenient for you.

Performance

A reliable and high-quality dehumidifier should be able to serve you for a long time. If that’s you, get the electronic rod version since they are known to last for many years. However, if this is not practical for you, then you can go for the more affordable version which is the desiccant type. This option does not need a power connection to work. However, you do need to ensure that they are always recharged to continue functioning. 

Visual Indicators

The best dehumidifiers are designed with visual indicators to help you know when it needs to be reactivated or recharged. Some models might come with different light indicators for different warnings. Keep in mind that the frequency of recharging your dehumidifier is influenced by the surface area it covers and the dryness levels of the gel beads.

Wired or Wireless

Depending on your preferences, you can choose a corded or cordless dehumidifier. Most gun enthusiasts prefer using the cordless version due to its convenience. However, the corded models may need some installation such as drilling the safe where the electrical wires can pass in. The good news is that most modern gun safes are already designed with outlets or a place to route a cord so that you don’t need to drill anymore.

Best Overall: Eva-Dry Wireless Mini Dehumidifier

Customer Reviews

“I use this little dehumidifier in my tiny bathroom. Even though I have a fan in the bathroom it still would get mildew spots from the steam. I've had this in the bathroom for a couple months now and I haven't noticed any new mildew spots. I have to plug it in every week or two since there is so much moisture in the bathroom, but that is a very easy process. I love the size and ease of use! ”
- Madeline Audrey

Product Description

We think that Eva-Dry Wireless Mini Dehumidifier is overall the best because it is 100% safe, renewable, and super easy to use. A single device is enough to cover an area of 333 cubic feet. Once fully charged, it can operate for up to three or four weeks which is longer than most dehumidifiers. The manufacturer of Eva-Dry also claims that the product can last for up to 10 years before needing any replacement. To ensure that they live up to their promises, the Eva-Dry unit comes with a 5-year warranty.

So how does the Eva-Dry dehumidifier works? The Eva-Dry is a type of desiccant that uses silica gel to absorb moisture and humidity inside your gun safe. The crystals turn orange when it is full and then changes to a green color when it is absorbing moisture. Hence, when it completely turns green, you can take it out and recharge for up to 10 hours. When the crystals change to orange again, then it is ready for use once again. Since the product does not need batteries or electricity to operate, you can save some money as long as you use the dehumidifier for up to a decade.

Best Budget Option: Barska Safe Moisture Absorber

“I haven’t seen the indicator go pink so I don’t know about microwaving it. But I got this for my car because in the fall and winter, it gets damp inside my car. As on the steering wheel feels damp. Since throwing one of these on the dash, I don’t have that problem anymore. ”
- LEE

Product Description

Another type of reliable desiccant dehumidifier is the Barska Dessicant Pack. It’s an excellent add-on to protect your valuables such as guns and jewelry from moisture, mildew, and corrosion.

The unit is made of highly absorbent silica gel that changes from color blue to pink when it needs to be recharged.

Pros

  • Available in two different sizes
  • Comes with stand legs
  • Easy to install
  • Effectively prevents condensation

Cons

  • Can be too hot to touch

Customer Reviews

“I bought a 18” for the bottom of my safe and a 12” for the middle and put them both inside. With a Digital temp/humidity meter my interior safe temps went up from 74 to 90 degrees and the humidity went from 77% down to 48%. It took several days to get that warm and dryer inside. Nonetheless I should not have any more issues with rusted guns and mold growing on my wooden stocks. I’ll go many months without opening the safe and there’s always mold on my firearms. Here in Texas these safes just get cool and lock in the moisture from humidity. ”
- Drew

Product Description

The Lockdown rod works its magic by heating the inside of the safe to maintain the circulation of warm air. Eventually, this process prevents humidity from increasing inside and keeps things dry.

Lockdown also comes with two different sizes to cater to different safe sizes. Another feature is that it is cleverly designed with a disassembled male plug so that you can easily pass it through from the safe to an electric port. 

Best for Versatility: Goldenrod Original Dehumidifier

Goldenrod offers durability and versatility. It does not get too hot to prevent yourself from getting burnt. Effectively manages the humidity levels while it keeps the temperature slightly higher inside the safe to prevent mildew and corrosion. 

Pros

  • Can be operated at 5 degree warmer inside the safe
  • Available in four different sizes
  • Bars never get too hot to touch
  • Comes with a lifetime warranty
  • Made in the USA

Cons

  • Mounting brackets are not stable
  • You need to drill holes in your safe for the electric wire

Customer Reviews

“Not sure where there's so much drama in some of the reviews. The one I got says, "Made in America" and does the job. Essentially what you're buying is a very small space heater to warm the air in your safe and thus dry the air. I also purchased a digital hygrometer to measure air temp and humidity.

Ensure you get the length right. You probably want the biggest one your safe can hold. Also, it's AC powered so your safe must have a hole for an AC line. ”

- SemperFiMac
