365 Dehumidifier Mini Review

What makes this little dehumidifier so special is that it uses non-toxic, odorless and colorless moisture absorbers to remove moisture from your gun safe. Plus, it goes about its job very quietly. There is no motor to disturb you as you work.

Another good feature that comes with this little unit is that it is rechargeable. After 2 months of use, the indicator will change color telling you that unit needs to be recharged. Recharging takes about 10 to 12 hours.

The indicator light will turn blue when the rechargeable dehumidifier is ready for action again. Also, you do not need extension cords, electrical outlets to get this unit to work. You just place it in your gun safe and forget about it.

On top of all that, this dehumidifier comes with its own hanger. This helps you keep the unit up and out of the way. To get rid of the stored moisture you just plug it in till the crystals turn black again.

What We Liked

  • No electrical usage
  • Small, compact and simple design
  • Odorless and non-toxic
  • It is rechargeable

What We Didn't Like

  • Some quality control issues
  • Inconsistent performance
  • Frequent recharging needed

Gurin DHMD-110 Renewable Wireless Dehumidifier Review

When you do not want to use up a lot of electricity protecting your weapons, this handy little dehumidifier will handle the task with ease. After about an initial 12 hour charge, it will work up to 60 days before needing more power.

An indicator window keeps you informed of how much life the dehumidifier has left. Then you just remove it from your gun safe and plug it in. After recharging it is good to go for another 2 months. This silica gel dehumidifier is designed to last up to 10 years.

The odorless, colorless and non-toxic crystals are child and pet friendly. They work risk-free and present no harm to you or your family. Once placed in your gun safe, these crystals will remove about 8 to 10 ounces of moisture over that 2 month period.

To recharge the unit, all you do is remove it from your gun safe and dry the crystals completely before filling them into the unit again.

What We Liked

  • Simple to use
  • Easy to recharge
  • Pet and kid friendly
  • 10 year lifetime

Stack-On SPAD-1500 Rechargeable Cordless Dehumidifier Review

It may be small in size but that makes it perfect for your small gun safes and other closed spaces. Just unwrap it and place it inside your gun safe and forget it is there for about 2 months.

After two months you should have 8- 10 ounces of moisture trapped in its non-toxic crystals. You do not have to change batteries or keep it plugged in to continue working. One overnight charge after a 2 month stint, is all that is need to keep this unit working for years.

The easy to see indicator light lets you know when it is time to recharge this dehumidifier. Once it is ready to get its power back, just plug it in to any standard outlet in your home.

One word of warning, do not leave it plugged in for longer than one night. It does get hot and may overheat and ruin on you.

What We Liked

  • The indicator light
  • The place it and forget it design
  • Works 24/7
  • No battery replacement

What We Didn't Like

  • May take longer than 10 hours to recharge

What We Found

Throughout our research, we were surprised at how little moisture is removed by these best gun safe dehumidifiers. Maybe we just weren’t prepared to notice that gun safes contained so little moisture.

With their long recharge time, it is necessary to have more than one of these little units on hand. That way you can keep your guns and ammunition safe while you are waiting for the original unit to recharge.

Another interesting fact we came across was that there are few unique models to choose from. Most of the ones we saw all used non-toxic chemicals and no batteries or electrical cords.

Most small dehumidifiers usually work in larger rooms and remove more moisture. They certainly would not fit inside a gun safe unless you owned a lot of guns and had a very large gun safe.

The ones we reviewed here today, work well for those small gun safes for gun owners who do not collect a lot of weapons or ammunition. They are efficient and do not use a lot of power.

The main thing to watch out for is overheating when recharging. Don’t leave them plugged in for more than their recommended recharge time.

What to Look for

When it comes time to purchase your next gun safe dehumidifier, there are some things you need to look for to make sure you get one of the best ones available. Here is a short list to help guide your search:

  • Power - if the one you choose needs to be plugged in then you will need to watch how many watts it uses as it works
  • Size - non-electric mini dehumidifiers seem to come in very small sizes and do not give you size selection. You are kind of stuck. But the electric dehumidifiers for gun safe do come in a variety of sizes so find one large enough to handle the cubic feet area of your gun safe
  • Convenience - the non-power dehumidifiers are just unwrap and place. This makes using them simple and easy. Convenience means you have time for other things
  • Moisture removal - the standard seems to be 8 to 10 ounces over 2 months. If you can improve on this all the better for you and your guns
  • Lifespan - the longer they work the better for you. You save money and time. Your replacement costs should be minimal if the ones you buy work well.

My name is Justin Williams. I am the founder and blogger at (read more about us). I was an allergy sufferer and that is also the reason why I began my trek to finding the best dehumidifier for my own personal health issues. All of the dehumidifier top picks on the site were put through their paces by Lance Perez - our dehumidifier researcher. He put each one through a series of tests to see how well they performed. Then, our editorial team compiled the insights into articles and published them.
