Product Description

Dehumidifier Benefits

The high capacity dehumidifier has been designed to absorb moisture from small enclosed areas. It will help protect clothes and valuables from the damaging effects of mold / mildew and moisture rot. It is 100% renewable and needs no power to operate. Just hang the eva-dry unit in a closet, or you can place it in other small enclosed spaces, and it will start absorbing moisture immediately. There are no batteries required or cords to plug in, the unit works without power.


There is an indicator window with special "moisture meter crystals" that change from blue (when dry) to pink (when wet) to indicate when the unit needs to be "renewed". The unit will absorb approximately 8-10 ounces of moisture (depending on humidity levels this should take approximately 4-8 weeks). Once the moisture has been adsorbed it cannot leak or spill. This unit uses a specialized engineered crystallized silica gel that is odorless, non-toxic and completely safe. When the indicator crystals turn pink it is time to "re-new" the unit. Simply remove the unit from where it is absorbing moisture and plug it into a power outlet in a well ventilated area (bathroom with extraction fan, garage, outside, etc.) There is a built in heater that will warm the crystals allowing them to expand and release the moisture as water vapor into the outside air. It takes about 12-14 hours to completely re-new the unit. When it is completely renewed the indicator crystals will change back to blue. The unit is brand new again and ready to absorb another 8-10 ounces of moisture. The crystals will remain active for 10 years and we offer a 5 year limited manufactures warranty on all EDV-500 units.

  • Super item
    I consider this an investment in saving what I have from humidity. It works great and is better than I expected. Does it's job, people should work as well as this item....more info
  • Worked better than expected in my keg fridge!
    I purchased this about a month ago for a beer keg refrigerator that kept collecting standing water on the bottom. I would use towels to soak up the half inch of water from the bottom of the fridge, but when I would open the fridge to check it again a week later, the water would always be back. Since I put this de-humidifier into the fridge a month ago, the fridge is still completely dry, and the beads have yet to change color at all, so I haven't yet had to "recharge" the dehumidifier. It's done just what I needed it to do. I'm very pleased with this purchase.
    To my surprise, it was over 7 months before any moisture appeared in the bottom of the fridge again. I plugged in the Eva-Dry for about a day and a half (until I could see pink beads again), and put it right back in the fridge, which has been dry ever since (1 month and counting)....more info
  • nearly useless
    I found this unit to be not substantially better than the 300 (basically the same unit, only larger). I have had this in a bathroom (quite small) and have recharged it twice in the first week. this is something of a challenge, as the plug is attached to the unit in such a way that it effectively hangs on the wall, but is really too heavy for an outlet where it doesn't rest on the floor.

    Despite it filling and being recharged twice it has not made any noticeable difference in a very small room.

    Although it is twice the price I'd recommend the petite electric over this unit- which for us has made no difference at all )in brief, no matter how inexpensive, a waste of money)....more info
  • its ok
    I bought this for my closet.. it seems to work pretty well It's definitely made for a small space....more info
  • It Works
    It does what it says- it absorbs the moisture from the air and leave the room dry. I use it in the bathroom and I bought another one for the closet....more info
  • short term fix
    Initially pleased with the ease and convenience of this product but after a few months, the crystals started falling out. Ended up throwing it away. ...more info
  • Does not work at all!
    Despite the mixed reviews on this product, I decided to buy it and give it a try for a small bathroom. It does nothing at all. I left it in the bathroom for a couple of weeks and the beads always stayed dark blue. The beads never turned pink to indicate that it was absorbing moisture. I sprinkled water on it to see if it would do anything......stayed dark blue with not one single pink bead showing. I laid a damp towel on top of it, completely covering this unit with the damp towel. IT NEVER CHANGED or gave any indication that it had absorbed any moisture! It's in my trash can now. At least it didn't cost very much but I'd not suggest this product to anyone....more info
  • So far so good
    I have only had the EDV-500 for a few weeks, so it hasn't passed the test of time but so far so good. I really like the concept; it seems like the perfect solution to a small damp area such as a closet. ...more info
  • it works!
    I had written a review for EDV-300 which I thought was for EDV-500. Anyway, I bought both and both work as expected! I used them both for my bathroom that's about 9 square feet. The mildew is visibly less and takes a longer time to build up. The mini one changed color after about a week of use and the EDV-500 started to change color now that it's about 1 month since I first started using it. One thing that I notice is that for the EDV-300 it changes color faster once you have charged it. It now starts changing color in about 2-3 days as opposed to 1 week. I need to see if that's the same case for EDV-500. But overall, I am very happy with my purchase....more info
  • Not thirsty
    We bought two of these items in early August. To date, they do not appear to have absorbed ANY water. Thinking that they might be dry because it has been less humid, we hung a disposable unit in the same closet -- which filled up in less than six weeks. The Eva-Dri 500 units we bought are doing nothing, a great disappointment.

    Followup: My Bad. The pellets were described in a way that led me to believe they were not absorbing (color change not pink). But upon plugging the units in, the pellets turned Blue, as they are supposed to when drying out. They now require regenderating about three times each month. The units work; they don't hold much. I would not buy again....more info
  • Violin started to die from humidity, but I rescued it with Eva
    If in summer your wooden instrument is constantly stored under high 65 and more percent of humidity it may damage your instrument. Now I bought large plastic container with lid where I put humidity measuring device, violin and Eva-dry. In about fifteen minuted humidity inside gets to 45-50 percentage, I remove dehumidifier and leave my violin be until next mornining when I check humidity again and if needed put Eva to its work once more. ...more info
  • Nice!
    I use this thing to keep the shotgun dry. It works great. Hopefully I'll never need the shotgun, but if I do it won't be rusted up...more info
  • good purchase - good price
    good purchase - good price - good service

    My one complaint is that I had to go online to find out how to hang the items in closets as there were NO instructions with the item on this, although a hanging apparatus was included and advertised. ...more info
  • EDV-500 big improvement over EDV-300 especially hanger
    I have 5 of these Eva-Dry rechargable dessicating dehumidifiers. Here in humid NC, using the larger in 4x8 closet works well. Takes some time, but definite measurable difference of 10-15% or so on humidity gauge after a couple of days. Need to recharge once a week here where even with the air conditioning on, indoor rel humidity is over 50% most days.

    The larger EDV-500 has a much better hook which fits through the holes in the Eva-Dry EDV-500 plug, a feature that is not very well documented!

    Also, there are occasional specials: recently a 2 for 1 sale on the EDV-500 with free shipping.

    Only reason for not giving this product a 5 star is that as stated in other posts, the recharge process gets the unit very hot and it doesn't always sit well in an outlet without support. I too had one unit fall, and was fortunate the case stayed intact but the little beads could make for a real mess if the unit broke open!

    But the real mess this thing avoids is dealing with drying chemicals that collect water and the dissolved dessicant. When that tips over, it is a wet mess, so the EDV-500 and EDV-300 avoid that type of mess.

    PS - where in the world did someone get the idea to label this "wireless" in the Amazon description? Very misleading!...more info
  • I think it works...
    I purchased the Eva-Dry EDV 500 as a last resort to try to get rid of a damp odor problem we had coming from underneath our whirlpool tub in our master bathroom. The tub sits on a cement slab on an outside wall of our home, with 2 interior walls on the side. The front of the tub is faced with wood cabinetry to allow us to get in under the tub in the event of a plumbing problem. The area is relatively small- about 6 feet across, 4 feet deep and about 2 feet high minus the space the actual tub takes up- I approximated it is less than 50 square feet of area. We started noticing a damp odor coming form under this area, probably because the wood cabinetry itself is porous and we live in humid south Florida. I got the Eva Dry EDV 500 to put inside this enclosed tub area, just right inside the wood cabinet door. I think it works! A long as I "renew" the Eva Dry about once a week, the odor seems to have gone away! As others have complained, it is very difficult to see the color change from blue to pink, but I have been re-charging it once a week regardless of what color I think I see. I am so aware of the problem that i am always in there sniffing to be sure it okay in there, so I always stay on top of re-charging the unit. I also do have to prop the unit up to recharge it as it seems to fall out of the electrrical outlet as some have commented on. I re-charge it in a side ways mounted outlet I have in my kitchen and prop it up with an address book that prevents it from tilting down. The unit does get very hot when recharging. I just leave it in over night and put it back in, in the morning. So far, so good. The odor seems to be gone and I am thrilled. Very pleased. I think you really need to be sure you are not putting it into an area that is too big for the size of the unit. The unit states, I think,that it works in ares of less than 150 sq feet. That is not very big when you figure the length X width X height dimensions of an area. Even a small closet is pretty close to that. For me, in this small under tub area it works!...more info
  • Works great! (but don't drop from high place)
    Kept everything really dry! When accidentally dropped however, hundreds of very tiny marbles came out that made walking very dangeous and they were hard to completely pick up....more info
  • So far so good!
    I haven't had the dehumidifer for very long, but it seems to be drying out this one closet that has always smelled musty. The closet is starting to smell much better! The fact that you don't plug it in is ideal since we had no outlets in there....more info
  • Great Dehumidifer
    Works great in both closets and cabinets. Very easy to regenerate. Looks like it will last forever....more info
  • Works better than I expected.
    I got this for a smallish 8-gun storage cabinet (really a kind of metal locker) I live in the woods here in Va. and we have a persistent dampness problem. This dehumidifier has been in service for a month and the indicator does not even show a hint of pink yet. Granted, it's been wintertime and the heat has been on, but there is a bathroom with daily showering only twenty feet away and our kitchen is directly downstairs from this room so there is moisture in the air for sure. I was expecting to have to be recharging this thing every couple of weeks, based on other reviews.
    Unexpected: This thing is pretty big. I was expecting a smoke-detector-size hockey puck sort of thing, but the E-500 is a big heavy chunk (loads 'o pellets in there) Maybe I didn't need one this big for my application but for $25 it is a good insurance policy....more info
  • Great Item!
    Works very well in small spaces, such as closets. To recharge, only plug in out of the reach of small children and pets, as it gets VERY HOT! ...more info
  • Works like a charm; love that it's renewable
    We were steaming off wallpaper in our house which is a pretty damp job, so I picked up two EvaDry units (the EDV-300 and the EDV-500) from Amazon, and I'm very please with the results. Both are very easy to use; just take them out if the package, set them in a damp area, and they go to work. The little globules that you can see through the tiny window on the front gradually turn from blue to a very light pink as they fill up with moisture. When they're all totally pink, you just flip out the fold-down plug on the back, plug it into the wall (it hangs by its plug on the outlet), and it dries itself out. When the globules return to a dark indigo blue, you unplug it and it's soaking up moisture again.

    Since the wallpaper project, we've been keeping them in a storage area in the basement, and they've effectively been removing the moisture (and the subsequent smells) from there as well.

    What's really neat about these is the technology. I love that it's renewable and easy to use, and I feel a lot better since it's in an enclosed case; I no longer have to worry about pet poisoning or toxicity like I have in the past with those white pellets that were exposed to everyone and everything to possibly touch (or eat!). This is a much better system, and I love that it's easy to use and creates no mess or waste.

    One thing to note is that they can get pretty hot if you leave them plugged in for a very long time (like a week). No problems, it just seems like an avoidable risk when you can just unplug them the next day or as soon as they're ready.

    Regarding another reviewer's concerns about his or her inability to distinguish the differences in color: If you're using them properly, it's incredibly easy to distinguish between the colors at their extremes (and I'm even a little bit colorblind). Yes, as it soaks in moisture, some beads soak it in faster than others, making some pink while others remain blue. But if you leave it alone and let it do it's job, it will be unmistakeable when they all become a very light pink. Same with drying out; the rich indigo color is unmistakeable. You may want to give it another try. ...more info
  • Same color all year long!!!
    This "Eva-dry 500" which I own has never changed color. It is always white (before & after recharging). But the idea (or add)was just great!!! Do you think manufacturer own us some refund ?...more info
  • Works, but the 8-10 oz are a big lie
    Good thing is, it works as described, but either my physics/math are wrong, or there is hidden magic.

    I had the unit out for 8 weeks, the stuff got extremely purple... so its soaked and full. Put it on a scale, about 950 grams, 24hrs later, 820 grams, that's 130 ml = 4.39582295 US fluid ounces. I'm pretty sure even if I would let it sit for a couple more weeks to soak, or dry even longer it would ever reach 8-10, dont even see the room where it could go.

    So basically its a dishonest description for one part, but the idea works....more info
  • It works....
    I got this item and thought,, this is never gonna work! I bought the damp rid hanging bags and placed them into my small laundry room before I bought the eva dry. They did work, but I needed more than one in my small room ( size of a small bathroom) but they didn't take away the damp smell. When I got the eva dry I imagined it would just do the same. I have now had it set up for about a month and I have no odor at all and the beads are still blue! I haven't even had to recharge it yet. You don't think its gonna work,, but it really does! I hang many items in my small laundry room and I am so happy that nasty damp smell is gone! ...more info
  • Works OK, not enough for my application
    Filled with standard chemical dehydrating material (color changing silca) this product helps, but does not eliminate the moisture that builds up in my chest freezer (13 cubic feet) that I use for serving homebrew. I use an external temp. controller to hold the temp at 32F for lagering (now sweating) or 50F for serving ales (lots of sweating).

    So I still have to wipe the moisture up with a cloth, but not as frequently....more info
  • I really like these.
    I've used them since September '08. They are not my primary de-humidifiers, but they work well for my shower and the closet. I would recommend them....more info
  • Usless near water
    I bought this for a 4 foot by 5 foot room with a shower. This room has no plug, so I purchased this item. I have to recharge it 2-3 times a week. It was a waste of my money....more info
  • Overall good product.
    Purchased 5 of these for small space (less than 30 cu. ft.) dehumidifiers. Having purchased multiple units, I can understand more of the comments read previously. Some of the units were still "dry" and had the dark blue tint that shows a dry condition of the media, while others varied with some showing more of a pink cast. Just simply "recharge" unit for 10-12 hours, it'll be dark blue, and put it to work. Units have mostly turned from blue to pink in 2-3 weeks with local humidity @ 50% or so. Use power strip on floor to recharge, and it'll work fine. Not sure this would be the right product if you needed something for several hundred cubic feet or more, but it seems to work great on small areas....more info
  • So far, so good
    So far, the Evs-dry EDV-500 works as advertised. It seems to be an inexpensive, space-saving solution for a small, perpetually humid bathroom. It took about a month to turn pink, & was easy to "recycle"....more info
  • good buy for kegerator
    I purchased this item to use in a freezer i converted to store kegged beer. Moisture is an issue due that even though the freezer is now maintaining only a 40 degree temperature, the inside wall still freezes in spots when the compressor turns on. Condensate would freeze and then melt, dripping into the bottom of the freezer. Moisture promotes mold and mildew which is not good when you're dealing with beer. When i placed the Eva-dry dehumidifier inside the freezer, this problem stopped occurring altogether. It's been a month and a half and i still haven't had to "renew" the humidifier. I'm not sure how well this item would play out in a bigger area, but in enclosed spaces it works like a charm!...more info
  • It works
    It works. I don't imagine it works or feel that it works, I know it does. The once (smaller than a closet) humid space I put mine in was all the proof I needed. The rest of this is detail... : )

    I use mine in a small area of ~12-15 cubic feet. Smaller than a closet. So I can't tell you how it would work in a larger area. The area I use this in is normally very humid though (about as humid as it gets) and it controls that perfectly although the long recharge time is of course an annoyance sometimes so be aware of that. It's not annoying enough for me to buy two of these yet but if they were free, I'd sure take a second one to use while the first is recharging at my leisure : )

    It's true that it can be annoying to plug in and dry out the crystals inside the until because the unit is heavy for its size and has no cord. However, I would rather have this inconvenience than the inconvenience of dragging around a cord that wouldn't get used so often anyway. (Maybe once a week or two for me). If you really want a cord, plug it into an extension cord, power strip, or use some other imaginative solution : )

    Just be aware that the unit has a somewhat long 'recharge' time in which to dry out the crystals for using again.

    If you pop on your reading glasses and put the recharge indicator under a light and you're not color blind, you should do fine checking when it needs recharging, it's fairly obvious. Even a color blind person would probably see the blue as darker than the pink because the blue is quite a bit darker and they don't all change color at the same time, so, you can see a contrast as it starts to "get full" with the humidity it's been collecting.

    Glad I bought mine! It eliminated my humidity problem without taking up a lot of space or electricity, makes no noise, and I don't get the feeling I'll need to go buy a new one in another month to replace it unlike a lot of other junk on the market..

  • Dehumidifier
    I basically got this item for free through a promotional deal on Amazon / with the manufacturer. As it needs to be used long term in order for a true assessment, I can't say much about it at this point. I will say that, even though it came with a hook for hanging, I couldn't, for the life of me, figure out where to put the hook. Yeah, it could be a "user error" but I kinda' doubt it. The product comes with minimal instructions....more info
  • Quite effective in small areas
    I was surprisingly pleased with the Eva Dry mini dehumidifier. I hang mine just out outside our guinea pig's cage and it absorbs excess moisture quite effectively, keeping their food and cage area from getting too humid. It takes several weeks to fully absorb moisture but the indicator will go from blue to bright pink, and the unit will be noticeably heavier. Just plug the unit into the socket overnight to refresh. ...more info
  • eva dry edv 500
    I dont think this will ever work, this is the second one i got and it doesnt work, i put in my closet that has the EDV 1100 that i also purchased and it still doesnt collect moisture while the EDV 1100 is collecting a lot. I dont recommend this product at all as a matter of fact I am returning it for another EDV 1100 NOW THATS A GREAT PRODUCT!!!!!!!!!!!!! NOT THE EDV 500....more info
  • Bad plug design
    I got the 500 for my 1.6 cubic ft. AMSEC safe for my handguns and important documents and use a wireless temperature/humidifier sensor to measure the moisture. It works well and keeps moisture at bay.

    Con: After a month and 2 renews, the unit stopped renewing. The unit would not heat up to release the moisture from the unit. Did a little troubleshooting and found that the collapsible power plug wouldn't make contact when plugged into the wall. This is the contact between the plug and the unit itself and not the wall. The weight of the unit when plugged into the wall would tend to pull itself away and cause it not to make contact with the unit. I verified this with a Fluke multimeter while pulling on the plug it would lose connection. The only work around is to charge it upright on a power strip where the weight would help give it a better connect.

    The unit gets very HOT! I assume this is normal considering it needs alot of heat to release the moisture from the unit. I'm just afraid it might catch on fire one day during a renew. To be on the safe side, I renew in the middle of my tile floor....more info
    Well I really Don't Know! it looks cool, its cleaner then its competitors,(No mess, No water to dump, No need to buy refills) But seriously You cant really tell if its working on not. Sure the crystals change colors, But hell I use to have a shirt that would change colors- remember those (I know sad). Like I was saying my condensation problem is probably so bad this little thing has no effect. I don't remember the area it is suppose to cover, But I would think it might be good for a food pantry, as long as you didn't have any liquids or can goods in there then it would probably work. or maybe is you bought six or seven of them they might show some sort of result. In my opinion out of five It's a three Just for design. I can't give it any more unless I actually new the amount of water it was removing from the air....more info
  • Ingenious Invention!
    Living in the tropics humidity is a HUGE problem. My clothes get moldy, leather actually rots. I have used the crystal system you can buy and refill and have not been happy. The collected water is very toxic and I have little kids, the containers can spill, and the replacement crystals are expensive and sometimes hard to find.

    I'm thrilled with this little device which is reusable indefinitely and does the trick! Just be carefully when drying out the unit, connect it to a power strip where kids and animals can't get to it because it gets really hot!...more info
  • Great Product
    Great little device.
    Really sucks up the humidity and the color change indicator makes checking
    the condition of the EDV-500 easy.
    Depending on the local conditions, may take 2 or three days to "recharge"....more info
  • Eva Dry works
    It's not a very exciting product, but it works as advertised. It has dried out the cabinet we bought it for and only needs recharging about once every month and a half....more info
  • works fine
    These units (I bought two and switch them when necessary) have kept our coat closet nice and dry. We had a problem with everything in there mildewing during the early spring when our old house's cellar gets wet and makes the first floor damp as well, and these have solved it. Very pleased....more info
