Was pleased with the size/weight/color/shape as soon as I took it out of the box. I’m no stranger to de-humidifiers; in my experience they’ve always been large, ugly, heavy, ungainly, and very loud. This unit is small and light-weight enough that I can put it in the center of my condo unit. This allows me to put it where it works most effectively without it taking over the space entirely like a larger unit would. Very silent too
Very easy to use and it’s a great size to keep in the bathroom to reduce the growth of mold. the humidity sensor is quite accurate and quick to respond in changing of the humidity.
I live in a tiny house that’s full of people pets and cooking, so moisture has been an issue since day 1. Getting COSMO has been a great help! About 1/3 the size of our other dehumidifier and so much quieter! And still manages to pull tons of water daily. I empty it each morning with about 2 cups of water.

This device has changed our lives! We had terrible mold and moisture issues which caused health problems in our old place. We live in a very humid area near the edges of singapore at punggol so mold is common but since we got this thing, we haven’t seen one bit of mold/ mildew.
This dehumidifier is excellent. It is more compact than other dehumidifiers I’ve had in the past, however, it is much more powerful and operates much, much quieter. I use this in my room and it works perfectly at keeping the humidity at the correct level. The unit is very easy to operate and move around. Having the auto shut off and drainage modes are a plus. I also like the built in timer if I just want to run the unit for a couple hours before having people over. I highly recommend this unit!
We have had moisture problems in our house (and mildew) with average humidity above 80%. We put the Cosmo in our master bathroom and ran the drain hose into the shower. It ran for 3 days straight and brought the humidity in the entire house down below 50% so we know it’s doing a great job 🙂
At first when I received it, we thought it would be too small. But after letting it run for a day in our bathroom, the humidity has dropped from 87% all the way down to 40%, there is a clear difference in air humidity.
The unit is pretty quiet on high with the compressor running. I have to sleep with a (loud) fan though and this dehumidifier isn’t nearly loud enough for me by itself so your mileage may vary.
This is a pretty compact dehumidifier and very easy to carry/move around.
I love this dehumidifier! What a difference it makes! My house has been so humid that my floors feel sticky. The humidity wreaks havoc on my sinuses and migraines and my brother suggested this dehumidifier after getting the cosmo air purifier. I was shocked at how well it works. Within an hour or so you could feel the difference in the air quality. The floors no longer felt sticky and the damp smell in my kitchen was gone.
I originally did not use the drain pipe to make sure that ‘dehumidifier’ is actually working as intended. I left it running for around 8-10 hours in the toilet. It stopped as intended as the internal tank was full. That gave me assurance that it was dehumidifying and sensors were working as intended. I then connected the drain pipe and kept it running continuously.
Reliably removes humidity from the air even in air conditioned rooms, as for the toilet, being near a body of water can make a place humid esp. In the mornings, and this dehumidifier does a good job. Hope it lasts — had it for about a week and so far so good.
I specifically wanted a unit with a compressor that would allow a constant drain into the shower by running a tube from the unit to the shower drain. Also the desired humidity can be set on it and the unit will stop running when the humidity level desired is reached. It will automatically start again if humidity starts to rise.
I recently purchased two separate dehumidifiers- one was a good bit larger (another brand), and the other was this cosmo. The cosmo was considerably smaller and far less obtrusive. The smaller cosmo unit works well, and it is performing as it should. The unit has 3 different speeds, including sleep, so you can reduce the noise level to a mere faint hum if you keep it on the lower speed setting.
I wish we would have bought this years ago. We live in KL, so the humidity can high here. We use this in the bedroom. This has been fantastic for better sleep and comfort at night (and day).
This dehumidifier is easy to use and move around. It definitely does the job. I had it and used it for one night. It has help drying time on laundry significantly. It’s not so heavy and easy to move around. It’s not noisy and very easy to sleep with
I wish we found this sooner. Pros: – Excellent size for how much moisture it takes in. – Needed emptied in first 10 hours, now about every 12-14 since with regular rainfall outside. – Humidity started at 90+, in 5 days were at 52-62 depending on the weather. – For the size the tank holds a lot. Cons: – Notice if needs drain beep is loud.
We upgraded to this unit after using another brand. After about a year the other model stopped pulling much water out of the air. It barely needed emptying once a week. This unit is night and day better! Thanks cosmo!
It’s only been running for maybe less than 3 hours and it already had several inches of water in the reservoir. Overall, this thing is out of the gate awesome. We’ll see how it does in the long term but at the moment, we are very pleased with the purchase.
I’ve had this dehumidifier for about 1 week now and am Impressed with it so far.
Best value around, just right size for my living room, don’t think you need larger size, just set this for low setting, its will run constantly until most moisture has been removed.
I had to replace a much more powerful unit but didn’t want to spend big bucks on doing so. Had my fingers crossed when ordering this one because it’s smaller, but it does not disappoint.
Works extremely well. I was hesitant on buying a dehumidifier. It is humid in my house, I live in KL but and wasn’t sure if it was going to make a big difference. I was wrong it made a huge difference. No more musty smells and much more comfortable. We now keep the air con a few degrees higher and the air just smells fresher.
I discovered that one of my bathrooms in our recently purchased house blows steam into our boiler room rather than to the outdoors. What a horrible design!!! The room is cinderblock and has been unusable until now. The humidity level was constantly in the 80s and 90s percentage wise so i tried to store tools but they’d rust or mold in just a few days. the dehumidifier has helped to keep the room around 50% without much issue and it blows my mind how much water it is pulling out from just the bathroom
This is an actual purchase that I am sending the review on. am extremely happy with the purchase of the cosmo prime dehumidifier, it’s amazing how much excess humidity is in a room. It has a very large container that collects the excess water it notifies you and stops working properly when the water bin is full.
Very quiet and efficient dehumidifier.
Smaller than expected, lightweight easy to move, very quiet. Used in my living room that pushed the maximum size limit. Humidity was over 70% so it took a while to lower it. Once it was down to to 50% it has easily kept it low. When registered it provides a full 5 year warranty.
This dehumidifier is a great size for my 3 room hdb and it is doing quite well. The humidity was sitting around 60% before I got the cosmo now with the unit, the humidity has been below 40%
My small house renter complained about mildew collecting on the windows so I put this dehumidifier in the house and she told me it solved the mildew problem. I really like that this unit has a drain hose. I can recommend this product. It works well
This is so easy to set up and use. The directions that come with this are super simple and easy to follow.
This is a nice unit. I definitely feel a difference when I have it on and when I do not. It runs VERY quietly. I have the hose hooked up to the little basin inside so I do not have to empty the bucket
We had a leak in the bathroom and add the humidity of 80%+ a mildew smell was starting to come. Worry about mold I decided to purchase this unit and so glad I did. I don’t have the drain hose hooked up so I have to dump the collection bin every 8 hours (that is over 3 litters of water removed a day). Within two days the smell was gone, and it just felt better in the room
Applaude for customer service, these guys are number one. I had a question about my unit, emailed customer service; and I received an email reply within 30 minutes. The company is very proud of their product and will work hard to earn your trust and your business. Not sure why I waited so long to purchase a dehumidifier, but I am definitely glad I did so.
First of all, I have had zero experience with dehumidifiers. I have been experiencing a lot of mildew on my jackets in the closet and on various surfaces. I have been using another brand for years but my wife continued to complain about the house smelling musty. Plugged the cosmo unit in and within a little over 2 hours the reservoir had collected 2 cups of water.
This is the first small size dehumidifier I have bought and I am pleased with it so far. Continues to work keeping the humidity of my living room at 60% level. I have it auto drain which is SO much easier then dumping it out 4 times a day. At this point I recommend.
When searching for a dehumidifier, I could only find either very large units or the little desktop variety. This one is perfect … very trim but has an adequate reservoir
It is lightweight but appears to be well made. It also runs very quietly which is a major plus for small spaces. The best thing about it, however, seems to be that once you have registered it, cosmo will send a refund or replacement unit if there are issues with it during the five year warranty period.
We have been using an older dehumidifier for the past few years to prevent moisture damage in our basement. However, after noticing a spike in our electricity bill, we decided to find a newer, more energy efficient model. This one is much smaller in size, easier to move, and quieter. It doesn’t become hot with use like our other one and has an intuitive operating panel.
Used for my living room. just nice 80m. Could not get rid of musty smell until I used this dehumidifier.
I have used this cosmo dehumidifier in toilet for a week now, and I am very happy with it! The first night I used it, the humidity in my toilet went from 80% down to 60% in just a few hours. I love how quiet it is. I honestly don’t even notice it’s on most of the time.
We’ve had this for a few weeks now, but so far, it has been doing the job. We have a very humid room, averaging 75% RH. We turn the dehumidifier on in the evening and by morning, we have a full tank and the humidity has gone down to 47%. It does warm the room up.
Only had this for a week and so far it really does pull out lots of moisture from the air. It does not surprise me as it is a self contained refrigerant split system with evaporator coil, condenser coil, and compressor. I do not use the hose, so I have to empty out the container once a night which goes to show how much water is being pulled out. My bathroom used to stay at around 74 degrees and 58 to 62% RH, now it stays around 76 and 35% RH. Notice it’s a bit warmer.
I live in KL where there is A LOT of humidity around the city. Mold and mildew were everywhere in the bathroom and on the wall next to windows. I have been using the cosmo dehumidifier for a week and I very happy with this purchase.
Bought the cosmo dehumidifier. I am amazed at the result. Floors are smooth and no sticking feeling at all. Very satisfied with the product. Its not totally 100% silent, but its bearable. Also, it said there is an air purifying filter for this & need to purchase it separately but there is no option on the website to purchase it. I only give it 4 star because the information on the coverage area always changes between 50, 60 & 80m2 on the website. Even customer service is providing different information on the coverage area. Until now I am not sure what is the coverage area for this machine. Please be honest.
