Eva-Dry Wireless Mini Dehumidifier, White (E-333)

Love that these are as simple as plug in to recharge. They take a little while to go from completely damp to dry and ready to use again, but so much simpler than the ones you have to toss in the ovenI've used this on a safe to keep moisture down, and it works great. It smelled musty before, and now this device keeps everything smelling fresh in there. Don't have to recharge often.Got a second one to keep in the laundry washer. It always would smell musty after using unless we kept the door open to completely dry out. Now, after letting it dry out over night, I stick this in there for the rest of the time, and it really controlled the odor and moisture level.Great little device!

I purchased this hoping to keep the excessive moisture buildup in my safe under control and couldn't be happier!About a year ago I purchased a First Alert fire proof/waterproof safe, which has an airtight seal. After I got it and read the instruction manual I found out that they state that the fireproofing materials used in the safe cause excessive moisture to build up inside the safe and suggest opening the safe on a regular basis and leaving it open to allow it to air out. This is obviously (at least for me) not practical since I got the safe to keep money and other valuables safe.I shrugged off their warning about opening it and placed my items inside and rarely opened it. I found out after several months that my money and other paperwork was very damp and smelled like mildew. So, then I started opening the safe more frequently, which did not help at all,, considering I live in Georgia where the humidity is already very high (so opening the safe just exposes it to similarly damp air.)The moisture was so bad inside the safe that liquid would actually pool on the bottom after being closed for extended periods of time.I then tried placing items inside ziplock bags, which did not work. Then purchased dry bags designed for keeping items dry when boating, etc, and even tried glass storage containers with ridgid plastic lids with gasket seals to place items in (this is what the manufacturer recommends). The dry bags didn't work and moisture still managed to work its way in. The storage containers worked better, but not perfectly.Then I purchased this Eva-dry E-333, which is the small one. I figured I didn't have that much to lose, considering that it doesn't cost very much. Well, I wish this had been my first purchase as this item works!The day I recieved it, I opened the safe and noted that there again was some liquid accumulated on the bottom. I placed the Eve-dry inside, along with the packing slip that came with it (to see how the piece of paper did being left inside the safe). I checked back the next day around the same time and all the moisture on the bottom was gone and paper was still crisp and dry. I then left it closed for several weeks and then checked again. This time I noted that the crystals had started to change colors (they were purple-ish-pink) and safe was still dry and paper still crisp and dry also.I then removed the Eva-dry and plugged it in to refresh it. The next morning the crystals were all blue again and I returned it to the safe.I had no problems with the plug or it falling out of the outlets. I does have a good bit of weight to it compared to a normal cord or power supply; however, if your outlets are good you shouldn't have any trouble. I had all of mine replaced about 8 years ago because many of the old outlets would not hold plugs well in general. If you have outlets like that, this thing will never stay connected, but not really a fault of the product. Using a power strip would also work fine, if needed.Bottom line - It works for my needs (small, enclosed space), you don't have to buy refills, and it's very affordable. I wouldn't recommend this to dehumidify a room, closet, etc, as I seriously doubt it would be that effective under those conditions. The reason I say that is that I've used regular electric dehumidifiers before, which are capable of removing a couple gallons of water every few days and although they make a difference in overal comfort, even those don't do much to lower the actual relative humidity reading within the space.

I purchased this on 6/30/25 for 14.95. I use it in my safe. It has done what it claims to do which is to reduce the humidity/moisture and help protect the items within. My only complaint is that it needs to be recharged/plugged in about every two weeks. Not really a big deal but I was hoping for more time between renewal. The other thing is - I looked at buying another one and the price increased about 4-5 dollars. Assuming it's made in the USA, I wouldn't think tariffs caused this increase.

He comprado varios de estos para mis propiedades y para mis inquilinos, y la verdad funcionan muy bien eliminando humedad y olores en espacios pequeños.Algo que muchos no saben (y he visto en algunos comentarios) es que sí se pueden cambiar los beads para extender aún más su vida útil.El truco es sencillo: en la parte de arriba, donde se sujeta el gancho, hay una tapa. Solo tienes que girarla, halarla, y puedes reemplazar las perlas de sílice fácilmente.Así, no tienes que desecharlo cuando los beads ya no funcionan, ¡simplemente haces un “refill” y listo!Son compactos, silenciosos, fáciles de usar y para clósets, gabinetes, áreas de almacenamiento o carros funcionan de maravilla. Muy recomendados si quieres una solución práctica y económica para controlar la humedad.⸻I have purchased several of these for my properties and tenants, and they work really well at eliminating moisture and odors in small spaces.One thing many people don’t know (and I’ve seen it mentioned in some reviews) is that you can actually replace the beads to extend the life of the unit even further.It’s very easy: on the top, where the hook is attached, there’s a cap. You just twist it, pull it out, and you can easily refill the silica beads.That way, you don’t have to throw the unit away when the beads are used up — you simply refill it and keep using it!They are compact, silent, easy to use, and work great for closets, cabinets, storage areas, or cars. Highly recommended if you want a practical and cost-effective solution to control humidity.

I bought this to help dehumidify my car since it’s older and get some moisture inside and winter. It works really well and as long as you remember to take it out and plug it in and dry out the beads. It works great. I did have a little issue, and I accidentally popped the plug out where the hanger is and spilled some beads. Other than that it’s been a total win.

I have purchased several different products in the past to keep moisture out of my gun safe. The Eva-dry is by far is the best!! I originally purchased a plug in/rechargeable one made by Hornady. It claimed to last 2-6 weeks before recharging. To my disappointment, it would only last 3-5 days before it indicated that it needed to be recharged. Next i purchased the bag version that you put in the microwave or oven. Same issue. My garage is heated/cooled so the temps do not get excessive either way so I knew there was something wrong. I purchased one of these and they easily last 4-8 weeks before needing to be recharged. They work so well, I even purchased one for my dad for a gift!
