The 7 Best Gun Safe Dehumidifiers

How To Dehumidify A Gun Safe? After extended periods of time moisture will cause metals to rust and corrode. This can happen to your guns if you do not keep the moisture out of your safe. There are different types of ways to dehumidify a gun safe so you will have to find the best gun safe dehumidifier that meets your expectations.

There are two kinds of dehumidifiers on the market.

  • Electric dehumidifier
  • Desiccant dehumidifier

If you do not have an outlet near the safe or you, choose not to drill holes in the safe you can go with the desiccant dehumidifier. The desiccant dehumidifier is like a sponge. It will pull all the moisture from an enclosed area. A desiccant dehumidifier can be reused for several months if you choose a good brand. If you have an outlet near your safe or you do not mind drilling holes in your safe, you can always go with the electric dehumidifier. An electric dehumidifier is more popular among gun safe users. An electric dehumidifier does pull out moisture from within the safes tight corners, but you will have wires running from the safe, and they have to be plugged into a power source at all times. You can find the best dehumidifier whether you prefer to work with the desiccant dehumidifier, or you do not mind having holes drilled in the safe and would prefer the electric dehumidifier. They all perform the same task no matter that one you choose.

Gun Safe Dehumidifier Buying Guide

Best Gun Safe Dehumidifiers

Finding the best gun safe dehumidifier might seem like a challenge in today’s crowded market, but you shouldn’t worry about it. In the following section, we explain how to find the right model for your needs, and how to use it to its maximum capacity.

Here are some features you should look for in a dehumidifier.

  1. Absorption Capacity – As you could see in our short reviews, there are multiple dehumidifier models you can use in your gun safe. As you can imagine, even though some of the models we reviewed are similar, all of them offer different absorption capacities. Most gun safe dehumidifiers rely on silica gel beads to capture the moisture. Dehumidifiers can hold more water if they contain a larger quantity of silica gel beads. As a rule of thumb, when it comes to silica gel dehumidifiers, the larger the dehumidifier, the better
  2. Size And Coverage – You should always make sure that the dehumidifier you choose will fit in your gun safe. The best way to make it will fit is to measure the inside of your gun safe and compare the measurement with the dimensions you find in the dehumidifier’s description. Besides making sure the dehumidifier will fit in your gun safe, you should also be certain it will be able to keep the moisture low in the safe. You can see how many cubic feet the dehumidifier can cover in most product descriptions.
  3. Ease Of Installation – Some dehumidifiers are easier to install than others. For example, dehumidifiers that rely on silica gel beads to capture the moisture do not need a power source, so you can simply place them inside the safe and that’s about all the installation they need. On the other hand, electric dehumidifiers will need access to a power source, so that might make the installation process slightly complicated. If your gun safe comes with pre-drilled holes for anchorage, it will be easy to install an electric dehumidifier. You will only have to pass the electric cord through one of the anchorage holes and plug it into an outlet. However, if your safe doesn’t have any holes, you will need to drill your own. The best approach to drilling holes in your safe is to either read the manufacturer’s instructions or to contact the manufacturer to see where it’s safe to drill without damaging the safe and to lower its security.
  4. Ease Of Use – Most safe dehumidifiers are pretty easy to use if you’re careful to read the manufacturer’s instructions. Each model has its plus and minuses, and it’s better to know what to expect before purchasing one.
  • Electric Safe Dehumidifiers – Electric safe dehumidifiers are very effective at keeping the moisture at low levels, but they might get too hot to touch at times. Since they’re too hot to touch, it might be safer to place them away from the ammunition, especially since the gunpowder inside them will be dry. Another thing you should be careful of when using such a model is to keep it away from flammable objects.
  • Silica Gel Dehumidifiers – Even though they might have an easy installation, silica gel dehumidifiers have a slightly higher maintenance than electric models. Silica gel dehumidifiers capture the water with their silica gel beads. The more beads they have, the more moisture they will be able to capture. However, no matter how effective they are at removing the moisture from the air, these beads will eventually become saturated, and you will need to recharge them.
  1. Price – Even though most gun safe dehumidifiers come at reasonable prices, there are some models that will make you think twice before buying them. And despite their high prices, you might be surprised to find that they’re really worth it. Here’s how to determine how much to spend on a dehumidifier for your gun safe.
  • Check Their Coverage – Gun safe dehumidifiers usually have a small coverage. Most of the more expensive models offer a better coverage than their competitors, which make them more appropriate for large gun safes. However, you should only invest in a dehumidifier that has a large coverage only if you own a large gun safe. Otherwise, you might end up spending money without having to.
  • Evaluate Your Guns – Even though you should always keep your guns dry to prolong their lifespan, some models are more affected by moisture than others. Antiques or replica firearms might be more affected by water than modern handguns and rifles. If you know some of your guns are susceptible to water damage, investing in an expensive dehumidifier might be worth it in the long run.
  • Check Their Maintenance Necessities – Some dehumidifier models are more expensive because they have lower maintenance necessities. If you know you’re one of the people who doesn’t really check their gun safes frequently, investing in a dehumidifier that has a lower maintenance level might be a sound decision. However, if you’re always cleaning your guns and taking them out, an inexpensive model that has a medium or high maintenance level might do the trick.

3 Main Benefits Of Using A Gun Safe Dehumidifier!

Using a gun safe dehumidifier offers a lot of advantages. These units don’t do much besides keeping the moisture levels low, but they offer multiple benefits.

  • Keeps Your Ammunition Dry – Ammunition is expensive. Whether you use a reloading press and make your own ammo or you buy cases of it, you know that losing ammunition is no laughing matter. Every type of ammunition comes with a limited shelf life, and if you store the ammo in a humid environment, its shelf life will be reduced significantly. And the worst part is, not only the ammo’s shelf life will be affected by the humidity, its performance will also suffer. Humidity will start degrading your ammo instantly. The process is slow at first, but over time you might find that your stockpiled bullets are no longer accurate, or worse, it won’t fire at all. Using a dehumidifier will reduce the moisture in the air and prolong the shelf life of your ammo by a long margin.
  • Keeps Mold Out Of The Safe – If you’re thinking that a safe will protect your guns from burglars and from the mold at the same time, you’re gravely mistaken. Sure, mold will most likely not grow on your safe’s walls, but chances are your safe came with a shelf or two that have a foam coating to protect your guns from scratches. Well, the foam is great at preventing your firearms from getting scratched, but it will also accumulate over time. And the accumulated moisture can lead to a mold growth if you don’t take some precautions. One of the most effective precautions you can take is installing a dehumidifier in your gun safe. Another good measure would be to install your safe in a well-ventilated and dry area.
  • Protects Your Safe From Rust – Your safe might seem strong and sturdy, but even the best gun safes can be affected by rust. And rust build-ups can cause permanent damage to your safe. Using a dehumidifier will not only keep your firearms dry, but it will keep your safe dry and rust-free as well.

Frequently Asked Questions

  1. How Can I Recharge My Dehumidifier?

There are two ways to recharge a silica gel dehumidifier. Some models can be plugged into an electrical outlet and they will recharge automatically. These dehumidifiers will get warm and the water inside them will evaporate, allowing the silica beads to capture more moisture. A full recharge might take as long as a whole night, but you only have to do it once or twice per month on average. Other silica gel dehumidifiers cannot be recharged using electrical outlets. These models have to be recharged manually, following the manufacturer’s instructions. You can recharge these models by following these instructions. First, you will need to remove the canister’s lid. Second, you will have to preheat the oven until it reaches 300 degrees F. Once the lid is removed and the oven is preheated, you will have to put the canister into the oven and let it dry for about two or three hours. Make sure you don’t touch the canister with your bare hands after you take the canister out and let it cool before you place it in the safe again

  1. Does Using A Dehumidifier Have Any Cons?

Honestly, using a dehumidifier can have some cons, but the pros outweigh them by a serious margin. Each type of dehumidifier has its own cons. The most popular are;

  • Increased Power Bill – Electric dehumidifiers rely on electricity to keep the moisture levels low. This means that using them will slightly increase your power bill.

  • High Maintenance – Silica gel dehumidifiers will need a high maintenance if you live in a humid area. If there is a lot of humidity in your safe, you might have to recharge the dehumidifier on a weekly basis.
  1. How Often Do You Have To Change A Dehumidifier?
