Best Gun Safe Dehumidifier Reviews 2018

#1. Lockdown Dehumidifier Rod

The Lockdown dehumidifier is another popular heating rod that sits at the bottom of your gun safe and increases the temperature of your safe. It’s a bit cheaper than the more popular GoldenRod, but it functions quite similarly. This rod comes with a one year warranty and heats up to 120 degrees Fahrenheit. It comes in just two sizes, 12 inches and 18 inches and ships disassembled so you can easily wire it through your gun safe if you don’t have an outlet inside.

This is perfect for gun safes that range from 18-36 guns. If you have a larger gun safe and live in a humid region, you may want to refer to the GoldenRod since it offers larger sizes.

The cord is 6 feet long so make sure your safe is near an outlet or have an extension cord ready to get power to the dehumidifier after installation. It comes with two mounting brackets to place the rod on. You’ll want to keep the rod on these if you plan on putting it on the floor of your safe. Direct contact with the carpet in your safe could cause damage.

Why Do We Like About It

  • Allows warm air to circulate inside a safe or vault to eliminate humidity, mildew, rust, and condensation.
  • Dries approximately 100 cu. ft.
  • 8 watts.
  • Includes mounting brackets and a 110V plug attachment.
  • Releases only enough heat to keep it dry.
  • Stays low to the floor of the safe, so it is out of your way at all times.

#2. Goldenrod Original Gun Safe Dehumidifier

The GoldenRod Dehumidifier is a heated rod, one of the best means of preventing corrosion of items stored in cooler areas, inside enclosed containers, and ideal for use in a gun safe. Millions of homes in the USA have a gun safe and many gun owners have written very positive reviews of GoldenRod products. Warming the air lowers relative humidity and, more importantly, increases the difference between the ambient temperature and the dew point.

This reduces the probability that water vapor will condense inside the space, damaging the items inside. The rod contains an electric heating element enclosed in glass tubing and insulated in Vermiculite, a naturally occurring mineral that is widely used for high-temperature insulation.

This form of construction makes the rod almost immune from damage in normal use and enables Buenger to give their product a lifetime warranty. The Vermiculite ensures an even heat distribution throughout the rod which contributes to its effective operation.

The GoldenRod Dehumidifier reaches a maximum surface temperature just below 150°F/65°C which would make it a little uncomfortable to hold with an unprotected hand but is well below the level which would ignite any household material, even paper, so is entirely safe. As well as lowering relative humidity the heat from the rod generates a circulation of air. If mounted, as recommended, on the floor of a storage container such as a gun safe, the warmed air rises to the top of the container. Cooler air replaces it and continuous circulation is established which also helps to prevent condensation. The warmed air expands, increasing its pressure, which prevents cooler air entering the container and preserves the “micro-climate” inside.

What Do We Like About It

  • Has a lifetime warranty.
  • Tough, durable design.
  • Offers permanent, maintenance-free solutions to humidity problems.
  • Provides enormous area coverage.

Types Of Gun Safe Dehumidifiers

1. Silica Gel

This gel is what many people use to keep their gun safe dry inside. because it is the little packet of stuff that comes with new items. If you purchase a gun safe, even one with a built-in dehumidifier, you will most likely have a silica gel pack inside of it to keep it moisture free while boxed up in a store waiting for you to take it home. They are a part of what is considered a desiccant dehumidifier and work by soaking up moisture like a sponge would do. They are a cheap option to use and easy to put in wherever you need it. You should change them out every couple months, but most can be put into an oven, dried out, and reused as per the manufacturer’s directions. Silica gel does not prevent moisture from forming, but it soaks it up when it forms.

2. Electric

An electric gun safe dehumidifier is one of the most expensive options, but many people feel that it is well worth it. It controls the moisture or condensation in your safe by providing the interior of it with a constant heat source. It resembles a rod, often it is called the “goldenrod” because it is nothing more than an exposed heating element that evaporates all moisture inside of the gun safe. However, electric does mean that you will have wires that must stay plugged in at all times. Some safes have electric outlets inside of them so it is easy to plug in. For safes without an electric outlet inside, you will have to run the wire through the door or create a small hole for it to pass through.

3. Wireless

A wireless gun safe dehumidifier is a battery powered unit that sits inside of your safe. The battery life is usually fairly good and it works to add heat to the inside of your gun safe. They are small, they are portable and work very well, especially if you are willing to use silica gel alongside it. There are some that include silica gel inside of them and as the fan circulates the air, the silica gel absorbs it. Most battery operated products have a lifespan of around 10 years. The only issue is that you do have to change out your batteries on occasion. If you forget to change the batteries your valuables could get damaged. We recommend setting some type of reminder if you are not a person that opens your gun safe often.

4. Desiccant

A desiccant dehumidifier for use in a gun safe uses a form of drying agent to draw moisture from the air. In other words, it works like a sponge to draw up all the water into the drying compound. There are a few advantages to using this kind of dehumidifier. The most obvious benefit is that it does not need electricity to operate. This means no drilling of holes into the safe and no wires running from it. This also means the gun safe can sit anywhere in your home without you having to locate it near a power outlet. Another great feature about desiccant dehumidifiers is that you can renew or reuse them. Depending on the specific model of the dehumidifier, the drying compound can last up to several months.
