Things to Consider When Buying the Best Safe Dehumidifier 

When choosing our products, we considered a number of factors ranging from its absorption capacity all the way to its price and other features. Knowing about these elements can help you understand your specific requirements and make sure you end up with the best possible unit for your purpose.

In the following section of the article, we will give you an overview of the things you should look for when buying the best gun safe dehumidifier.

  • Types of Dehumidifiers

Before you can commit to a dehumidifier, you need to understand the different types that you can find. Generally, there are two main types of units that you can buy, electric dehumidifiers or silica gel dehumidifiers.

  • Electrical Gun Safe Dehumidifiers
  • The best thing about this type of dehumidifier is its efficient moisture control. However, it tends to get extremely hot. There is a potential for severe disaster if you place them too close to your ammunition. Furthermore, you need to keep it separated from flammable objects inside the safe.

  • Silica Gel Gun Safe Dehumidifiers
  • This type of unit is simple and straightforward but requires some maintenance. It typically has a lower absorption capacity and requires you to recharge frequently. But a silica gel dehumidifier is easy to install and extremely affordable, making it perfect as your first purchase.

    As you can see, both variants come with their own distinct set of advantages and setbacks. If you want higher absorption capacity and lower maintenance, and electrical dehumidifier might be what you want. However, if you are on a budget, there is nothing wrong with a good silica gel dehumidifier.

    • Absorption Capacity

    One of the most important factors in a dehumidifier is its absorption capacity. It refers to how much moisture it can absorb before you need to recharge it. Some models use silica gel beads while a few use crystals. You also have units that use steel rods to absorb the moisture.

    Take a look at the total amount of moisture it can absorb before committing to buy it. If the capacity is too low, you will need to recharge it more frequently. Typically, if the unit uses silica gel beads, the larger the size, the higher the absorption. With other moisture absorption mechanisms, that may not be the case.

    • Size and Coverage

    Size is also an important factor when buying the dehumidifier. It needs to fit inside your safe without taking up too much space. You can find the dimensions of the unit listed under product specifications to give you an idea of how much space it will consume.

    However, size is not the only thing you need to worry about. Each unit has a maximum area of coverage. If the coverage area is too small, it will not be able to fully absorb the moisture from the safe. In that case, you need to use two units for a single safe, which is not really worth it.

    • Installation difficulty

    The installation process and difficulty can vary from one dehumidifier to another. For instance, installing a silica gel bead dehumidifier is extremely simple. Since it does not require any batteries or power connection, you can simply place it inside your safe after activating it, and it will do its job.

    However, with electrical dehumidifiers, you need to drill a hole for the power cable. If your gun safe already has the mounting holes pre-drilled into it, the process becomes much easier. You can use the holes to run the cable inside the safe to connect the dehumidifier.

    In case your unit does not come with mounting holes, you need to drill it yourself. You should consult the instruction manual before starting the installation as some safes might not handle the drilling process too well. The last thing you want is to compromise the security of your gun safe just to install a dehumidifier.

    • Ease of Use

    When it comes to using dehumidifiers, it is pretty simple and straightforward. Make sure you read the operation manual thoroughly when you get your hands on the device. It should get rid of most of your confusion and questions regarding how to use it.

    Whether you buy an electric dehumidifier or a silica gel unit, make sure that it is easy to use. Look at all the safety instructions and operating procedures to get an idea of how it works before setting it up. If it seems too complicated for you, you could have a better experience with a different unit.

    • Price

    Although there are many high-end expensive dehumidifiers available on the market, most units are quite affordable. Unless you are facing massive moisture-related issues, there is no reason to exceed your budget. In fact, almost all the products you saw on our list of reviews are in the affordable range.

    So, it is important to have a clear and concise idea about how much you are willing to spend before you start browsing the market. If you do not have a budget in mind, you might end up going for a highly expensive unit that might feel like a waste after a few days.

    • Evaluate Your Guns

    Most people, when buying a dehumidifier, make the mistake of not checking their arsenal before committing to a product. However, that is a big mistake as some weapons react to moisture at a more dramatic level. If you are using any antique firearms, an affordable dehumidifier might not be able to do the job.

    In that case, you need to shell out a bit extra and invest in a higher-end model. Before buying a dehumidifier, it is worth checking how your weapons react to moisture in the air. If the effect is minimal, you would be fine with a normal dehumidifier in the affordable range.

    • Maintenance Requirements

    If you want to buy a unit that gives you a hassle-free experience, you need a unit that requires minimal maintenance. However, those units do cost extra, but if you consider the upkeep cost, it might be worth it for you.

     But if you check your guns frequently, taking care of your dehumidifier is not that difficult. Ultimately, it all comes down to your preference

    Frequently Asked Questions 

    Do I need a dehumidifier for my gun safe?

    If you live in a humid environment, having a dehumidifier can be highly beneficial. It would ensure the quality and finish of your weapons remain intact when it is left in the gun safe for an extended period.

    How do you recharge a silica gel bead dehumidifier?

    Typically, silica gel beads do not require any batteries or other forms of power. But in some cases, this unit requires an electrical outlet to recharge. There is also a different form of units that can be recharged in the oven.

    The idea is to heat up the gel beads so that the water inside can evaporate freeing up space to capture extra moisture. Some units require charging the whole night for the water to evaporate fully. But once charged, it usually lasts at least a month without any problems.

    Are there any disadvantages to using an electrical dehumidifier?

    Both electrical and silica gel dehumidifier comes with some minor disadvantages over the other. None of them are perfect, and there is always a small compromise that you need to make. For instance, an electrical dehumidifier will generally result in an increased power bill at the end of the month.
