I love this little personal dehumidifier!!
I have had a big problem in my master closet. I have purchased reusable hanging dehumidifiers, the various types of throw away absorbers and after seeing my leather jackets and shoes with mildew, I finally bit the bullet and purchased this personal dehumidifier. I truly wish I would have done this a long time ago. I would have saved alot of money. This little dehumidifier is not overly large so it is not taking up much space on the floor of my closet. It is extremely quiet and will shut off if it gets too full. I try to empty it ever 2 or 3 days but if I miss I know it will not overflow. It is very portable and easy to empty. I can see a remarkable difference already. I have been using it for about a month. My clothes no longer smell damp and mildew is no longer on my shoes, jackets or purses. I would totally purchase this again. UPDATE...It is Oct of 2021 and it has stopped working. I contacted the company for its warranty and they responded quickly and will be replacing the unit. I can already tell a difference in my closet without having it running. I received a replacement within a week. The new one is improved with a built-in power cord instead of the power transformer type plug.

Small, Quiet, Cool, Effective!
I received this three weeks ago and couldn’t be happier. We’ve had problems with humidity on our boat and I don’t like the excessive plastic and expense of Damp-Rid, so these small dehumidifiers caught my eye. I read through a lot of reviews, and this one seemed the best in terms of sound (it’s practically silent), water capacity (much larger than the competing models I considered), and heat output (none whatsoever, so this little beauty doesn’t compete with the A/C). I purchased the protection plan just in case, but I couldn’t be happier with the product. It’s small, about the size of a smaller bathroom wastebasket. It’s sleek and sharp yet unobtrusive, with just a small blue light bar—no flashing color show. Best of all, it works beautifully. Our interior area is about 140sf and moisture removed from the air in a week’s time far exceeds that of two DampRid 14-oz. hanging bags. I plan to buy another, as I’m using DampRid in a finished basement and last week opened a new bag only to discover the following day that it was defective and leaking on a nice rug. When I wiped it up the water collected was gross and oily, so not only is there a lot of plastic waste with DampRid, but the moisture collected seems like a pollutant. Thankfully, I found a solution in this COSVII unit. Highly recommended for smaller spaces!

Worked great for me!
This dehumidifier has helped me so much! My apartment is very humid because my roommate has a bunch of tropical house plants, and the moisture condenses on the exterior walls in the winter time because of the temperature difference. The walls are textured too and I had big problems with mold growing behind furniture. I put this dehumidifier in my room and sometimes it filled nearly half way full in just one day. It is quite quiet and I can sleep with it on without much issue. The blue light that is constantly on is a bit bothersome at night, but I just cover it up. The auto shut off is very helpful so I can leave it run during the day and not worry about it. Great purchase, and good bang for your buck.

Great for a bathroom without a fan
We live in Tx where it is already super humid and one of our bathrooms does not have a fan. When showering it needs a way to remove the humidity to help prevent mold and this was our answer. I purchased a digital temperature gauge that also had humidity on it to see how well it works. This works great! I removed the gauge and put it in another room because we know this is doing its job. This is in a fairly large master bath and helps decrease the humidity to a proper level within a few hours. It is small and can be moved or placed in a more conspicuous place. You could easily move it around if necessary. It is quiet and I don't even notice it when it is running. I'm always amazed at how much water is pulled into the device after it has run, but we don't have to empty it that often. Does the job, would recommend!

Works like a charm!
Living in a tropical area surrounded by trees, nature, peace and quiet may sound nice, but it also means you can't have nice leather (and other materials) items because of the one downfall of this type of environment: humidity! For years now I'd been keeping Damp Rid and similar companies in business, spending more than I'd like to admit in disposable solutions that didn't really help as much as I expected. I'd also considered getting a large capacity dehumidifier, but couldn't find one I was convinced by until I decided to give the COSVII dehumidifier a try. I can't stress enough how GOOD of a real solution this has been; this is actually my SECOND dehumidifier as I bought the first one to try it and just had to get a second one. I put these in my closets and from day 1 you could tell the difference: the moldy smell is gone and even mold itself has disappeared, not only did it stop growing, but the existing one vanished! The 2L tanks fill up in approximately 3 days which is when I dispose collected water and place the empty tanks back in; some days I choose to turn on the ACs after the 3-day use to give the dehumidifiers a rest, but they definitely have made a difference and I highly recommend it specifically for small spaces such as closets.

Works well
First off, I’d like to say that this does remove moisture from the air. I can tell because I empty the container approximately once a week( I live in a humid climate).I was amazed how much water it removed from the air! The unit is compact and super QUIET which is important because I use it in my bedroom. Great unit for bedrooms, bathroom,etc..where humidity is a problem. I had purchased a much larger dehumidifier unit but it was too big and way too loud so I had to return it. The COSVII dehumidifier is PERFECT for small/medium sized rooms and because of its compact size, it can be moved from room to room with ease. All in all I am completely happy with my purchase and would highly recommend .

Not impressed
Ordered this after reading glowing reviews at Amazon. Had just sent back a COSVII dehumidifier that didn't do crap. This was twice the price and I thought it would be an uupgrade. The only upgrade I can see is the water tank is bigger. Also, it didn't arrive filthy like the COSVII dehumidifier did. This one doesn't do crap either. After several days with it, it maybe gathered 8 ounces of water, Not as advertised, and seriously I don't understand all the reviews saying how great it works. I live in Memphis, TN and it is very humid here. In the hot summer it is so humid it is a labor to eveb breathe. My bathroom barometer measured 60 to 65 humidity percentage. After running all night in a room with water on the bathtub floor and sides of the sink.... almost nada and the wet pools were still there. OVERRATED. Don't buy the COSVII dehumidifier or this one. You get the same lack of dehumidifying the air. Put in the kitchen after opening the dishwasher to let out the steam and air dry the dishes. Guess what? This piece of s*(&^% hardly did anything in a very small kitchen that had been steamed by the wet dishwasher and dishes. Pitiful. It finally started working in the humid summer of Memphis.

Great value for small grow tent! On/Off switch works well with climate controllers.
Great for a small grow tent, say like a 2ftx4ft or 4ftx4ft or a little bigger. I bought two to run in parallel in opposite corners of the tent, I may buy a third! The switch (vs. most have a button) makes it easy to operate with a controller such as an inkbird and power loss recoverable, so you can maintain the humidity easily with sensors and the 68oz tank gives you enough capacity to run a few days. The big gain over an equivalent unit such as a mini-dehumidifier from VIVOSUN, is that this unit has a decent fan for moving air through itself as well. You can feel a good breeze on your hand from it. Place some white gorilla tape over the lights or take it apart to disconnect them during flowering! Great value, perfect for small grow tents. Just keep buying more of them till you get the desired effect! (Haha)

Easy to use and useful
I bought this dehumidifier for my bathroom in the suite. I found it is easy to use and it works well. Before using this device, the bathroom was very humid after taking shower, because the ventilation fan is not efficient enough. After showering, I let it run for a couple of hours. It reduced humidity, and it is quiet when it is running. By the way, I can move it around easily since it is not heavy. I am satisfied with it. I should have bought this earlier.

Speedy delivery
Delivered very quickly, this little unit works well. Getting up to a liter of moisture from the air is impressive for this type of dehumidifier (non-compressor), and the two-liter tank is fairly good. Much better than my two other small dehumidifiers, which work very well but only each pull .5 liter of moisture from the air and have 1.5 liter tanks. A nice little upgrade here, which is also much quieter than the other two while taking only marginally more power (48 watts vs 40 watts).

Excelente solución
Me parece una excelente solución para los problemas de humedad. Es elegante y en efecto “capta” la humedad qué hay en un cuarto, lo único que me gustaría saber es cuánto tiempo seguido puede estar conectado (encendido) para que no se dañe. Yo lo dejo encendido 48 hrs y lo apago por 6 hrs para que no se caliente PEEO LA VERDAD NO SE SI ESTA BUEN O MAL Ojalá puedan ayudarme

Efficient but maybe not so effective
I have been using this dehumidifier for a couple of months now. I like the low noise level and the low-ish energy consumption, but it’s not terribly effective in drawing moisture out of the air. Maybe I was expecting too much?

Excellent Size for Small Spaces
We purchased this unit for our basement cold room (20ft x 4ft - with standard height ceiling). It has been running non-stop, without issue, for a few weeks. It is able to keep the humidity around 45%. It's easy to see at a glance how full the water is and easy to empty the water chamber (auto shuts off when chamber is removed). A quiet little unit, I'm very happy with.
