Two dehumidifiers perfect for a gun safe.

Best Gun Safe Dryers on the Market Today

Here are eight of the best gun safe dryers to help keep your firearms from getting rusty.

Gun safe dryer or vault electric dehumidifier, whatever you prefer to call it, having a product that will remove the moisture and keep it away from your prized firearms can make a good gun collection safe from rust, corrosion, and mildew that may damage it. And while we may love our favorite gunsmith, we would rather have their help mounting optics or helping us sight in than removing unwanted rust.

Fortunately, there are products that monitor temperature and humidity in your gun cabinet. There are others that are more specific to absorb moisture from a basement or other enclosed area. Either way, a good gun safe dehumidifying product will give gun owners peace of mind during those times when our firearms and other valuables are simply in safe storage.

Some of these are made as plug in style, some are rechargeable, and others still can simply be heated in an oven to remove the excess moisture they've taken from your gun vault and retuned to it to start the process all over.

Some dehumidification devices remove moisture from the environment inside of our gun cabinet or safe by raising the temperature to lower the humidity, or by drying the air inside the vault mechanically. Others may use a silica gel dehumidifier (a desiccant) to absorb moisture from the air. This moisture can then be removed to recharge the device.

This can both be beneficial not only to all of our firearms, but also any ammo stored with it. With that in mind, these are some of our picks for the best safe dehumidifiers on the market today.

SnapSafe Reusable Canister Dehumidifier

This is one of the simplest models to choose from that works and works again by simply placing it in the oven at 325 degrees until the silica gel turns back to blue.

Other Things To Consider

A good quality hygrometer will allow you to monitor the temperature and humidity level inside of your gun safe for those with higher end gun collections, or for those who just want that extra level of care for their prized firearms. A gun safe dehumidifier should not only take the moist air from your gun storage area, but take away the worry about the effect it can have on your firearms. They are generally anywhere from $20 to around $50 with a few being a bit more expensive.

It almost goes without saying that if you have your guns stored in a locker, cabinet, safe, or vault that you should be minimizing the moisture level inside of it. That said, there are many good choices out there for the gun enthusiast to keep in mind and hopefully one of these can help.
