Best Gun Safe Dehumidifiers

Save your gun safes.

Buying a gun safe is the first step in securing your gun safe from unauthorized access and dangers like fire and floods. After you’ve got yourself a gun safe, your firearms and other valuables stored in the gun safe face another threat, humidity.

Since a gun safe is an enclosed structure, it has the same humidity levels and temperatures as the outside. Your guns are made of steel, iron, and wood which can be damaged when exposed to humidity. Different parts of your home have different humidity levels. Have a look at the table below.

For the longevity of your firearms, it is important you store your gun safe in a humidity controlled environment. Keep your gun safes away from chimneys, kitchen, garage, and the basement as they have high humidity levels.

If you only have space in the highly-humid areas in your home, you can still save your guns from being eaten away by excess humidity.

Why Dehumidifiers?

While you can’t stop humidity, you can save your guns from it by installing a dehumidifier inside your gun safe. The dehumidifiers cost a fraction of what the gun safes cost and are worth buying considering you can have thousands of dollars worth of valuables inside your gun safe.

Many people don’t open their gun safes very often which cuts off the air circulation inside the safe. Changing temperatures in the room where the gun safe is installed can cause the temperature inside the gun safe to fluctuate. This temperature fluctuation can cause moisture to develop which can corrode and rust your guns.

Different Types of Dehumidifiers

There are three types of dehumidifiers you can choose from for your gun safe. Each type of gun safe has its pros and cons depending on your needs. You will need one of these dehumidifiers to keep your gun safe moisture free.

Silica Gel Dehumidifier

Silica Gel Dehumidifier

Silica gel dehumidifiers are the basic type of dehumidifiers. The silica gel inside the gun safe is used to keep the moisture out of the gun safe. The silica gel dehumidifiers are also known as desiccant dehumidifiers.

If you buy a gun safe, it comes with a silica gel packs inside. This is the cheapest form of dehumidifiers and you can put them wherever you need them the most. You need to change these silica gel packs after a couple of months.

You can also put the silica gel packs in an oven to dry them out after reading the manufacturer’s instructions. A silica gel pack won’t stop the humidity from forming inside a gun safe but will soak the humidity already present inside the gun safe.

Electric Dehumidifier

The electric dehumidifiers are the most expensive type of dehumidifiers present on the market. The electric dehumidifiers resemble a rod and can control the moisture formation inside your gun safe by providing a constant supply of heat.

Most people find the electric dehumidifiers to be the best solution to the humidity problem which justifies the few extra dollars you pay for it. The only drawback for this type of dehumidifier is, you need to keep it plugged into an electricity source at all times.

If you get an electric dehumidifier, you will have wires running through the walls of your gun safe. If you don’t have a pre-drilled hole in your gun safe, you will have to drill one yourself. Most of the premium gun safes come with a provision for electrical connections.

While there are many different types of gun safe dehumidifiers present on the market, most of them are overpriced or don’t perform well. The first decision you need to make while buying a gun safe is to decide whether you want an electric, rechargeable or a silica gel dehumidifier.

Look at the amount of humidity in the area your gun safe is placed in. Depending on the amount of humidity, you should go with the appropriate dehumidifier. If your gun safe has a high amount of humidity, you should go with an electric dehumidifier.

Gun safes with a moderate amount of humidity can make use of a rechargeable dehumidifier. Go with the silica gel dehumidifiers only if your gun safe has close to no humidity. Spending a few dollars on a dehumidifier can save your valuables from moisture, mold and mildew, and musty odors.
