Rotary Desiccant Dehumidifier
vs. Compressor Dehumidifier
Quiet, efficient moisture reduction in areas up to 4000 cubic feet.
You can find the cubic feet of space by multiplying three linear measurements—length, width, and height—in feet. For example, to find the volume of a cube, calculate the following: length x width x height. The products of this formula will return the volume of an object in total cubic feet (CFT). The result will help you choose which dehumidifier is best for your space.

I have been using my EDV-4000 for 2-3 years (can’t remember the date of purchase), but she has worked beautifully whenever I need it on my boat in SWFL. I was initially concerned when the unit stopped producing a drainage, but the RH was staying extremely low, around 32-35% RH, inside my boat. I set the unit on a ledge above my galley and ran the drain hose to the sink for ease of maintenance. I particularly like using the Turbo Dry Mode to take the chill out of the air on these 40-50° chilly mornings in December and January. !

Versatile Unit. Shipped quickly and nicely packaged. Unboxed, plugged in and it went right to work. Quality plastics and fit and finish thru-out. Excellent printed User Guide! Control panel is easy to use and has a lot of options given your use. Noise levels on low are suitable for any location, on high the unit would be not welcome in a living space. The unit has lots of LEDs, so use in a bedroom would be difficult for most, given the light produced. The drain hose is a bit vexing, but Eva-dry does sell a proper hose (would be nice if they put a link right on the product page!). The unit does remove a lot of moisture in the basement of my home, which is around 55 degrees. The older compressor model I had struggled in the cooler air and was a lot noisier; the Eva-dry works better, is quieter, lighter and has a smaller footprint. All wins. One concern is I don’t see any certifications from UL or ETL etc. on this Chinese made machine. While this seems a well made unit, I’d feel better if the unit had a certification.

I have owned this dehumidifier for years now and I am writing a review about it as I am shopping for additional Units for a Florida Trailer that is not able to stay dry and has developed a mold smell in the back room and the living room. I have always used my device in a area that was made into a beautiful viewing area that was created from a porch so it has always been a problem. I am able to actually have my bedroom in there with my dehumidifier so I am positive that I HAVE to purchase the same type of
Dehumidifier for the new problems. Yes, there are some less expensive options that are out there but it’s not a good idea to buy a product, save a few bucks, when I know that a slightly more expensive version will do the job and give me years of of exceptional service! This is a good product and I am sure that you will be happy with your purchase.!

I bought this dehumidifier about 3 years ago and it is absolutely the greatest! It is quiet and efficient. I use it in my partially finished basement which is also my art and music studio. The ionized air smells so fresh which is really important for a basement. I have to empty the bucket out every day during the summer when it gets humid (I live in Alabama) but since I am down there everyday anyway, it’s just part of my routine. I most definitely 100% recommend this product – it is worth every penny. Thank you, Inventors, for bringing us such an awesome product!!

Best you can buy… Ours is over 3 years old and runs almost year around here in Florida…

I purchased the EDV-4000 in September 2018 for a basement studio apartment that is almost exactly the square footage recommended for this unit. The humidity is very high and I’ve battled with mold and mildew issues. I’ve been using the EDV-4000 a little over 4 months and it has performed wonderfully well! It’s relatively quiet and the design is great – it’s compact and lightweight compared to other dehumidifiers on the market – a good quality product. It’s easy to empty, easy to clean (although it hasn’t really needed much cleaning), and does a great job keeping my apartment humidity down. Since I’ve been running it, the mold issues have gone away. I would definitely recommend it!

Bought two as needed them for each side of my basement. These are efficient and so quiet vs compressor dehumdifier!! I bought longer drain hose to reach drain on other side of basement. I wish the electric chord was longer for far side cellar so I could move it around more but working without reposition unlike the compressor dehumidifier. Lastly, I wish I had read your instructions on attaching drain hose as I had difficulty not taking off those bucket lids. Great product, Will run both year around in northeast, loving electric savings too!!

Working well. I wish it were a bit quieter.

Worked great to remove humidity from our camper while on the Gulf coast. Pretty quiet and simple to use.

I’ve lived in the SouthEast for the past 20 years and have used indoor dehumidifiers since then. The variously branded big-box store dehumidifiers in the $100 to $150 range all worked about the same. Removed humidity and lasted about 2 years at best. I finally “splurged” on a top DeLonghi unit with the built-in pump and was amazed. Four (4) years and still going strong, keep the humidity below 50% in the summer! Well, looking for the “next best thing” I purchased this not-inexpensive EDV-4000. Why yes, it is quieter and smaller, but that’s about it…. Revised rating. The stink with the original unit dissipated after about 2 years of use. Since the unit is much quieter than a compressor-based unit, I ordered another. Eva-dry has been working on the problem! The new unit has no odor and works well. It still doesn’t remove the volume of water, per day, that the better compressor-based units do, I now recommend this unit.

Was apprehensive trying this new technology, but year two, no problems yet. I was replacing our de-humidifier every year. They are all junk. Freezing up ect.
This one uses ceramic heating plates, and during the humid time of the year it ŕeally strips the moisture out of the air. I leave it on “Auto” mode. Not sure if the ionization function is actually doing anything.
But overall I would buy another. One negative is it does not include a drain tube. Very difficult to size, 12mm inner diameter- ended up stretching a surgical hose over the drain port, including having to make the access hole bigger on the side to get my fingers in. Emptying the small tank everyday does get old.
I hope Eva-Dry designers take note: include a drain hose please! And make it easier to connect!
Thanks….

I use this in the RV when its not being used. Drain it directly into the sink. Keeps it smelling fresh and dry. I like it so much I bought a 2nd one for our vacation home.

I’ve waited to write this review until I had some time and experience operating this dehumidifier.
We’ve had the Eva-Dry EDV-4000 for about four months now and have it plugged into a Dayton 1UHG2 dehumidifier controller (sold here on Amazon). I *highly* recommend you purchase this controller with this unit. It has a more sensitive built-in hygrometer, and it can measure the ambient room humidity from a location separate from your dehumidifier. Even if you purchase a different dehumidifier than the Eva-Dry, I suggest you purchase this controller. We have ours connected to a utility-room plug located about four feet off the concrete floor, so it’s measuring the humidity in a more central location, rather than close to the floor. The Dayton controller also keeps your dehumidifier from cycling on and off. The Eva-Dry will do this to “sniff” the air and determine whether it needs to dehumidify. I would expect that this reduction in operating time will extend the life of the unit, since it’s not cycling on as often.
The Eva-Dry saves its settings when powered down, so it operates well with the Dayton controller. If you purchase a different dehumidifier than the Eva-Dry and plan to use the Dayton controller, be sure to purchase a dehumidifier that saves its settings when powered down.
So far, we’re very pleased with the Eva-Dry dehumidifier. It’s much smaller and lighter than we expected, which is a good thing. It’s very attractive and appears to be of excellent quality. The control panel is flat with detent push buttons that control the various features. LEDs display settings, and an autorotating baffle can be used to direct the flow of air up and down. It can also be placed in a stationary setting, if you need airflow focused in a specific direction.
We installed it next to our sump pump, so I needed to install a drain hose in the back of the unit. This hose it not included with the dehumidifier. I found this part of the installation to be a real pain! Another review here stated that they called Eva-Dry and Eva-Dry stated to use a specific size I won’t repeat here because it doesn’t work. I purchased that size and the hose simply doesn’t fit. I returned it and then went to two different big-box stores and brought the dehumidifier with me, trying to match a hose. Neither store had a hose that fit. I asked for help, and the person was unable to find anything in the massive store that would work. As I was about to leave, he came running up. “Wait! Wait!”
What he found was right next to the store’s dehumidifier section. Clipped to the edge of the shelving, right next to where the dehumidifiers were located, were bags labeled, “Dehumidifier Hose”. These fit perfectly! I was soooooo happy to locate this! I can only think that the hose is a standard size for dehumidifier drains? I don’t know… All I know is it works.
The message here is, if you buy this unit, go to your local big-box store (I went to the one that starts with an L) and look for dehumidifier hoses next to the dehumidifier section. Assuming they have similar stock located in the same area, you should be good to go!
Once the hose was installed, I plugged the unit into the Dayton controller, set the humidity level, and waited. Eventually, the EDV-4000 kicked into action.
The first thing I noticed was the strange smell others reported here. It’s a chemical smell, presumably from the desiccant used during the dehumidification process. It’s a little off-putting, but I didn’t have a major problem with it. Being in the lower level of our home, I was able to ignore it. If you’ll be placing the unit in a bedroom or a common living location, you should consider how you’re going to deal with this smell once you receive the unit. I found the smell went away after a few days. It could take upwards of a week, depending how often your dehumidifier cycles on when you first get it. We only noticed the smell when the dehumidifier was actually operating. When it’s off, there’s no smell.
We find the sound level to be very acceptable. I’ve been around dehumidifiers in the past that have a different quality of sound when the unit cycles on. These units have a combination of sounds. The fan and compressor each combine to form two layers of sounds that mesh together into one overall noise. This isn’t the case with the Eva-Dry. The Eva-Dry has only one white-noise hush that may be about the same decibel level as some compressor-type dehumidifiers, but I find the Eva-Dry to be much more tolerant simply because of the quality of the sound.
As an example, our Eva-Dry is in the lower level of our home. We have a futon bed down there, which I used recently when we had guests at the house. Sleeping down there, the Eva-Dry was probably twenty of so feet from where I was sleeping. The unit cycled on and off periodically through the night, but I slept right through it quite comfortably. The reason is it has a white-noise hush. I sleep well with this quality of sound. A regular dehumidifier has a white-noise sound from its fan, but it also has a rattling sound from the compressor. It’s a different quality of sound that would probably wake me up if I were trying to sleep around it.
As for dehumidification, I can only base this on the digital display on the Dayton controller. The Dayton not only reports a drop in humidification levels, but it also gives evidence of this by cycling off the dehumidifier at periodic intervals. Our lower level is only about 500 square feet. The Eva-Dry dehumidifier does a fine job keeping things dry down there.
We’re very happy with the EDV-4000. I’m very pleased that I learned about a desiccant dehumidifier. I’m very dubious over the quality of standard dehumidifiers these days. They seem built to fail in two to five years. This didn’t seem to be true when I was younger in the 1970s. We had a dehumidifier that operated fine for close to twenty years. I’ve had a number of friends who seem to go through them in only a few years. I don’t want to have that experience. I’ve rolled the dice and am taking a gamble with the Eva-Dry in the hopes that it is more reliable and lasts for many years to come.
I promise I will update this review and report ANY issues I have with the Eva-Dry EDV-4000. I’m very active on Amazon and pay close attention to the reviews I write. I’ve been writing them since 1997. If you don’t see any additional comments in this review, that means our dehumidifier is doing well and running fine.

I love my EDV 4000 by Eva dry. I’m using it in my office/music studio, and after using a disastrous frigidaire FAD 70 pint dehumidifier, I couldn’t be happier. My frigidaire was noisy, rattled, and guess what! It had an automatic shut-off when the bucket got full. Automatic shut-off? Hell! it shut off alright, went to work one morning and when I came back home my studio with my piano and $30000.00 church organ was completely flooded, and the damn thing was still running. I’ve had several different dehumidifiers over the years and that frigidaire was the pits! I have this unit on awall mounted controler, so that I can have more precise control than the controls on the unit, I like my humidity especially in my studio at 42 to no more than 45%, and my EDV4000 does this superbly.It does have a small water bucket, but mine is emptying into a condensate pump which takes it outside of the room. The fan isn’t that loud really, and in all honesty, it’s the compressors that make the shakes rattles, and junky sounds that you get from some dehumidifiers, especially those Wretched frigidaires! Good God! I truthfully think you will be quite happy with this machine, especially if used in a bedroom, office, or even your living room. As a piano technician, I _know what humidity can do especially in pianos, and that’s why i’m really picky about a dehumidifier. I hope this has helped you, and one last thing, if you do buy this unit, invest in some kine of drain hose, you can get one for this machine for about $7.00and with such a small tank, about 2 leaders, believe me! it’s worth the investment.
Thanks for reading, take care of yourself, and have an awesome spring and summer.
See ya next time with another review.
