Most individuals would go to any extent for their family’s safety, which sometimes includes purchasing a gun. Buying a gun safe is essential for storing your firearms when not in use and kept away from family and safe from accidental discharges, ill-usage as well as burglary. However, just buying a gun safe is not always enough to keep your firearms secure, as though it will keep guns securely, but a gun safe cannot defend itself or gun from high humidity levels. Metal is reactive to moisture, and excess humidity in the air can trigger metals to rust and corrode over time, with the top layer of the metal can slowly start to flake off.
One of the biggest problems in keeping a gun in a safe is that humidity levels inside a closed, airtight safe can build up and damage your gun, especially if you don’t open the gun safe regularly or live in a humid place. Since the air inside the gun safe is not regulated, the trapped moisture inside can be relatively high.
Keeping your gun safe in optimal humidity levels is essential to prevent firearms and accessories from developing rust, corrosion. If left untreated, rust and corrosion may cause permanent damage to the gun safe, firearms, and any other metal valuables in the safe. Besides rust and corrosion, high moisture can lead to mold and mildew growth. While not impacting metals directly, they cause an unpleasant odor and can severely damage fabrics, gun paperwork, or accessories, such as holsters.
Using a dehumidifier is an excellent option to regulate internal humidity levels and reduce mold and mildew build-up in your gun safe. They protect our firearms from getting damaged by rust and retain their cosmetic integrity and optimal functionality.
Types of Gun Safe Dehumidifiers
Silica Gel
Silica gel dehumidifiers absorb the moisture through hygroscopic beads and crystals. Higher the number of beads, the more amount of moisture they can absorb. Once these beads become saturated, they need to be recharged or replaced.
There are two types of silica gel available in the market, single-use and rechargeable.
Single-use silica gels can be utilized and thrown away after absorbing moisture to its capacity. They are available in disposable pouches and bags and are a convenient and hassle-free option. However, since single-use gels need to be discarded periodically, they tend to be expensive in a long time and are not environment-friendly.
Rechargeable silica gel crystals and beads can be charged through electricity or heating, once they absorb moisture up to capacity. This type of silica gels dehumidifiers are available in electric or canisters. Electric beads or crystals can be plugged in to be recharged, while canister beads can be placed in an oven for drying. Rechargeable silica gel beads are affordable, long-lasting, non-toxic, spill-proof, and easy to install. However, they have a lower absorption capacity and require frequent recharges.
Electrical Gun Safe Dehumidifiers
Electric gun safe dehumidifiers reduce the humidity levels by warming the air. It also increases the difference between the dew point and temperature, lowering the likelihood of condensation inside the gun safe. While electric safe dehumidifiers effectively keep moisture at low levels, they tend to get extremely hot, which might become problematic if kept too close to ammunition.
Electric dehumidifiers are more flexible than desiccant dehumidifiers in humidity and temperature settings. The downside of electric dehumidifiers is that you need to drill holes in the gun safe for wires. If you want higher absorption capacity and lower maintenance and are willing to put holes in their gun safe electrical dehumidifier, it is ideal.
Heating rods
Heating rods, heat the air inside the gun safe, reduce condensation and moisture, and prevent mold and mildew growth. Heating rods require an electric connection and can be easily mounted. On the downside, they need active electrical connections inside the gun safe, and they cannot remove moisture odor.
Dryers cum dehumidifiers
Dryer cum dehumidifiers absorb the moist air and release heated air back in the atmosphere. The dual-function brings down the humidity levels smoothly and efficiently.
Advantages of a Gun Safe Dehumidifier
Portable: Gun safe dehumidifiers are compact and easy to move around, and don’t take much space in the gun safe. Moreover, they are easy to install and remove.
Long-lasting: Gun safe dehumidifiers come with a long-life span, with some lasting for up to ten years before needing replacement. A lot of manufacturers are now also giving lifetime warranty and years of trouble-free service.
Keeps Ammunition Dry: Ammunition is expensive and comes with a limited shelf life. If they are kept in a humid environment, it will impact their longevity as well as performance. A dehumidifier will reduce the air’s moisture and keep it safe from rust and mold growth.
Reduce Rust: A dehumidifier can keep rust and corrosion from impacting the guns as well as ammunition. If not prevented, it can lead to permanent damage or costly repair.
Prevent Mold and Mildew Growth: Most gun safe shelves are made from foam coating to protect weapons from scratches, and over time these shelves may accumulate moisture, which can lead to mold growth.
Affordable: Dehumidifiers are designed to save you money in the long run. Some dehumidifiers don’t even need batteries or electricity to run, so apart from the initial investment, there are no major running expenses.
How to choose the right Dehumidifier for your Gun Safe
To pick the humidifier that will address all of your needs, here are the things you should consider when buying a gun safe dehumidifier
Absorption Capacity: This refers to the amount of moisture the dehumidifier can absorb. An electric dehumidifier can be operated continuously if required to capture any amount of moisture. On the other hand, desiccant dehumidifiers rely on silica gel beads to capture the moisture. 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.
Size and Coverage: The dehumidifier needs to fit inside your safe without taking up too much space. Also, each unit has a maximum area of coverage. If the coverage area is too small, it will not fully absorb the moisture from the gun safe.
Installation difficulty: Installing a silica gel bead dehumidifier is relatively easy since it does not require any batteries or power connection. For installing electrical dehumidifiers, you may 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 more manageable. Please consult the instruction manual before starting the installation as some safes might not handle the drilling process too well.
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.
Evaluate Your Guns: When buying a dehumidifier, most people overlook the type of arsenal they have. While you should always keep your guns dry to prolong their lifespan, some models are more sensitive to moisture, especially antique or replica firearms. If you are aware that your weapons are susceptible to high humidity, investing in an expensive dehumidifier might be more beneficial.
Coverage: Gun safe dehumidifiers are generally able to cover small areas. Most of the more expensive models provide a better range, making them more appropriate for large gun safes. You should select the dehumidifier according to the size of the gun safe as putting a high capacity dehumidifier in a small safe will waste money and make the ammunition too dry, which will also impact its performance.
Charge Time and Duration: Most desiccant dehumidifiers contain beads or crystals that recharge by heating them. Electric dehumidifiers beads take anywhere from 4 to 12 hours, while canisters one can be heated in an oven for as little as two hours. The idea is to heat the gel beads to evaporate the water inside, freeing up space to capture extra moisture. Once charged, it usually lasts at least a month without any problems.

Here’s our process –
When we think about dehumidification, the challenges faced in humid buildings or spaces are different from the humidity challenges in enclosures such as cabinets and safes.
We have considered the absorption capacity depending on your climate; it is a critical factor. For example, if you live in a naturally humid environment, your device needs to be absorbing a lot of moisture for half the year, making capacity important. Apart from the volume absorption, we have also considered the amount of moisture it can absorb before being drained or replaced (such as desiccants/silica gels).
We have also considered size and coverage as they are essential for smaller enclosures. You want it compact enough to fit well into the safe without compromising the space needed for guns, ammunition, and related tools.
Another critical point that we have looked at is the ease of installation. Corded Gun safe dehumidifiers are robust and provide efficient dehumidification; however, they are challenging to install, especially if your safe doesn’t already have wires running in for lighting and other purposes. In addition, you may need to do significant modifications to get power inside where it can plugin. In this case, you probably just don’t want a corded device, opting for wireless or a desiccant instead.

Other Measures to Keep Humidity Levels Low in a Gun Safe?
Put the gun safe in a cool, dry place. You must make sure that the gun safe won’t suffer from too much heat or moisture inside or outside. It is common to put a gun safe in the basement, but make sure that your basement doesn’t have dampness issues.
Checking your safe regularly will easily prevent this scenario. If the humidity does rise, place a fan near the safe to keep the air fresh and cool. Remember that this is only a temporary solution to a humidity problem.
Use charcoal, baking soda, or coffee grounds. Please place them in an open container inside the safe. Plenty of people trust these desiccant materials to absorb moisture in any scenario. However, it would help if you replaced them regularly since they cannot be recharged as a desiccant dehumidifier can.
Protect your guns from rusting. You may use numerous products such as sprays and creams, to keep your guns free from rust. Remember that taking good care of your guns allows them to remain dry and clean, which is essential to keep them from rusting.
Humidity levels shouldn’t be kept too low, either, as the low humidity can dry up your ammo. Ideal storage conditions occur at 50% humidity. You must continuously reassess the climate where your gun safe is situated, as the humidity levels might change with the weather.

FAQs
Should I Install a Dehumidifier in My Gun Safe?
A good gun safe will protect your firearms from theft and fire but may not protect your valuable guns from rust, corrosion, mold, or mildew. You can ensure that your gun safe remains dry is by using a dehumidifier. They are highly effective in preventing condensation and moisture and protecting your guns from rust, corrosion, and other harmful elements.
How Effective Are Gun Safe Dehumidifiers?
A majority of gun safes are made from steel and iron; hence it is imperative to keep the humidity levels low to avoid rust. Dehumidifiers in gun safes do an excellent job at reducing humidity and moisture to a comfortable level.
Where To Place A Dehumidifier In Gun Safe?
As airflow is restricted in a gun safe, it can accumulate moisture, resulting in rust and mold on the guns. Dehumidifiers should be placed in an accessible location, ideally at the bottom of the safe. First, separate each firearm or weapon in the safe to prevent potential accidents by keeping a reasonable distance between them. Most advanced gun safes come equipped with pre-drilled holes at the bottom for the cords to pass through. Depending on the gun safe size, you can place the dehumidifier near the door, front, or deep inside.
What Level Should Gun Safe Humidity Be?
Per the National Rifle Association (NRA), the ideal condition for gun storage is humidity between 30% to 50%. Anything lower than this may risk damaging your wood stocks from dryness. If humidity rises above 50% inside the safe, it will cause condensation on the firearms, eventually leading to rust. Many people use gun safes for storing photographs, cash, or jewelry which may also get affected by moisture. Purchase a hygrometer to check the humidity levels inside your gun safe.
How do the Best Gun Safe Dehumidifiers Work?
Gun safe dehumidifiers are available in two types: desiccant and electric. Desiccant dehumidifiers absorb moisture just like a sponge. These are often rechargeable or disposable. They don’t use electricity, so you can place them directly inside the safe. They are ideal for a smaller gun safe because they can’t extract large amounts of moisture.
Electrical Dehumidifiers use heat to lower the humidity levels. Remember that you will need access to a constant power source for an electrical dehumidifier.
What size dehumidifier do I need for my gun safe?
If your gun safe is smaller than 100 cubic feet, then a 12-inch extended model would be enough; on the other hand, if your gun safe is more than 300 cubic feet, consider a dehumidifier that is at least 24 inches long.
How long do gun-safe dehumidifiers last?
Gun safe dehumidifiers’ have different lifespans; disposable desiccant dehumidifiers need to be replaced within a day, while others may last for up to 10 years.
