Best Dehumidifier for Gun Safe in Garage Buying Guide

Why Should You Buy a Dehumidifier for a Gun Safe?

Humidity can spell big problems for firearms. Of course, all you want to do is protect your guns from any moisture, rust or dew, and a dehumidifier can help with this. A good dehumidifier will help to control the humidity level inside of the safe.

You may not be opening the safe very often so this will help to ensure that mold and mildew don’t build up. A dehumidifier will also help to ensure that your guns don’t rust or get damaged by moisture, and will protect especially old firearms that are more susceptible to water damage. 

Types of Dehumidifiers

There are a few main types of dehumidifiers for gun safes to look out for. First of all is the electric rod. These dehumidifiers are quite frequently used for getting rid of any mold, moisture or corrosion that’s made its way into the gun safe.

It essentially works by heating up the rod through an electrical current, and the air inside is warmed. This means that the air inside of the dehumidifier is warm so moisture won’t build up from cold air penetrating inside.

This safe is ideal for keeping your guns totally dry, and it also makes very little noise. You don’t even need to charge it on a continuous basis, you just need an electrical outlet nearby.

You could also opt for a silica gel dehumidifier. These are also referred to as desiccant dehumidifiers. They’re a pretty popular option, and they don’t require batteries or electricity to work. It makes no noise because no power is actually needed for them to operate.

There are two key types of silica gel on the market. The first kind is a recharge silica gel and the other is a single use gel. You can usually get the single use ones in environmentally friendly bags. They’re pretty easy to use but they cost a lot of money.

You can reuse the recharge ones over and over again, without even needing a power supply or battery except to charge them. When the beads change color completely, you can charge them using a plugin power outlet for around 8-12 hours and then use it again.

Finally are dryer style dehumidifiers. These are sort of like dryers as well as dehumidifiers, and they are designed to release warm air into the safe, and remove any moist air from the safe. Unfortunately you are going to need a hole in the safe so you can put the wire through it to reach the electrical outlet. It operates on electricity.


You should always make sure that you check the coverage of the dehumidifier that you are planning to get. You may find that your safe is too big for your dehumidifier to cover it - some dehumidifiers have a limitation in cubic feet.

Usually though, most dehumidifiers will have a minimum cubic feet coverage of 100 cubic feet and can go up to 500 cubic feet if your safe is bigger. If you have a larger safe just double check that your dehumidifier of choice has the coverage that you need.


If you have a tiny safe, it makes no logical sense to have a dehumidifier that is almost as big as the space it will occupy.

As you may expect, then, it’s important to consider the size of your safe when you are making your purchase. 

The ideal dehumidifier will be the one capable of completely getting moisture out of the safe, all while being barely noticeable inside of it.


Nobody wants to spend a lot of money on something for it to simply fall apart hours after setting it up, and you don’t want something that’s going to need to be charged all the time.

If you would prefer to have a low maintenance dehumidifier, then it’s best to opt for an electric rod. If you would rather something that doesn’t need electricity to operate then you should instead get a desiccant dehumidifier. 

Types of Firearms

Before you buy your dehumidifier you should also consider the kinds of guns that you have inside of the gun safe. This is because older guns are more likely to get damaged by things like moisture than other sorts of rifles or handguns.

So if your gun asfe does have a lot of older firearms then you should get a more expensive dehumidifier to keep them safe for longer.


A lot of gun safe dehumidifiers are pretty affordable, but this isn’t necessarily true of all dehumidifiers. Some prices can be staggering, so you really need to consider what you need first of all. There’s no use in spending a fortune on a dehumidifier if it isn’t going to do what you want it to do.

Before buying, consider the long term cost of running the dehumidifier, think about what kinds of guns you have and think about the coverage. These are all factors that should play into your decision.

Installation and Use

Not all dehumidifiers are easy to install. Ideally you don’t want to be spending hours attempting to set up a dehumidifier if you can avoid it though.

Some are much easier to install - for instance, silica gel dehumidifiers require no power, so all you need to do is put them inside of the safe and they’ll work that way.

Alternatively, some electric dehumidifiers require access to a power source, which can sometimes cause some problems. For instance, you may need to put some holes in the safe to run the wires through.

If you need to do this then you will have to check the manufacturer’s guide to see where it’s safe to drill holes. Sometimes it’s easier to avoid this altogether and simply buy a less high maintenance dehumidifier for your safe.

You should also think about how easy it is to use the dehumidifier. Most of them are fairly simple to use, but some can be more awkward than others. Assess this before you buy your dehumidifier. 


Some dehumidifiers can make a lot of noise. Sure, if it’s in your garage then it may not bother you so much, but it’s still pretty annoying if you’re in the garage doing some maintenance on your vehicle, for instance.

Before you buy your dehumidifier, then, you should make sure that it is quiet in operation to spare you and your neighbors no end of annoyance in the long run.

Frequently Asked Questions

What’s the best humidity level for a gun safe?

If you can you should try to get a humidity gauge to figure this out - it will tell you the precise humidity level of your gun safe.

If you don’t have a gauge, then you should try to aim for a number that’s below 50%. A number above this can make your guns more likely to rust. 

Is it a good idea to keep a gun safe in a basement?
