Tips on Choosing

The following four questions are commonly asked by new gun-safe owners, and they can help you determine what kind of anti-humidity setup you need to install.

Do Gun Safes Need Dehumidifiers?

Almost every gun safe will need a dehumidifier. Warmer climates will not need them as much as colder climates will, but this is subject to the location of the safe within a home.

A safe in a damp washroom or garage will suffer from humidity issues despite being in an area with high average temperatures. The colder and damper the room is, the more expedient it becomes to have a dehumidifier to protect your weapons.

What Is the Best Humidity Level?

Humidity gauges can be acquired for very little, and they can tell you exactly how humid your safe is. Shooting for a number below 50% is ideal, for guns can rust above 50%. A safe without a dehumidifier can easily reach 70% humidity, and this level will rust weapons quickly to cause permanent damage.

Electric dehumidifiers are excellent for knocking out 20% humidity, so they should be bought for areas with high levels of moisture content.

Are Basements Good Place for Gun Safes?

Theoretically, any place is good for safe as long as it is secure. It is feasible to place a gun safe in a basement and protect its contents from the damp atmosphere with a strong dehumidifying system.

A well-constructed electric dehumidifier should be acquired, and it should be paired with silica-based dehumidifiers to combat high water levels.

Additionally, a humidity gauge should be bought to make sure that the interior of the safe can sit below 50% humidity. It will cost labor, time, and energy to keep the humidity levels down, but putting a gun safe in a basement is possible with the right system in place.

How Does a Gun Safe Dehumidifier Work?

Electric dehumidifiers work by keeping a safe temperature high enough to where water levels drop in the air. This results in less condensation and moisture gathering on firearms when placed in small, confined areas.

Silica-based dehumidifiers work by soaking up water in the air and storing it until it reaches its maximum carrying capacity. It is advisable to combine both methods to lower the humidity levels in a gun safe.

There can be too little humidity in a gun safe if too many dehumidifiers are used, but having too little humidity is easily remedied by removing pieces from your setup. The main problem is having too much humidity, so having a humidity gauge can let you know exactly where you stand in this spectrum.

Conclusion

Choosing a gun-safe dehumidifier can be complicated, tricky, and stressful. Everything is broken down in this guide to make the process simple, however. The best gun safe dehumidifier for you can protect your guns in the environment that they are in.

If you live in a desert with low humidity, consider going for an electric-free device to protect your guns at night. Living near open bodies of water can require a system that is much stronger, such as electric models with multiple silica-based devices in place.

These 10 units from various manufacturers can be paired together to achieve ideal humidity levels. After a day of shooting and target practice, being able to store your weapons safely without them being exposed to developing rust is imperative. A good dehumidifier will do the job of keeping you safe ideal for firearm storage.
