I initially gave this a 3 star review since I thought the unit was failing (see original review below). However, I eventually figured out the drain line had become clogged with a biofilm and gunk buildup. After clearing the line, the unit works correctly. It seems that the tube wasn't able to keep up with the rate at which the unit produced condensate. Below is my original 3 star review so you can see how the issue manifested. I got this in July 2024 and it worked quite well until summer 2025. At that point the function that allows it to drain through a hose stopped working so suddenly you had to manually empty the tank every couple of days.

We have been using this dehumidifier for several weeks now. Here are our initial thoughts- Pros- It works, pulling well over a gallon a day out of the air. Easy to use, and has a running display of the humidity level. It's relatively quiet, like white noise. Rolls easily on casters from one part of the house to the next. The design is clean and sleek. Thought we might need a drain hose (it has connection for this), but its an easy matter for us to empty once of twice a day, either outside or in the shower. It does have an overflow shut off in case you forget. Cons- Feels a bit delicate and "plasticy", but as long as you are reasonably careful it shouldn't be a problem. The reinforced packing tape is nearly impossible to remove. Took way more patience than I would have thought to remove and clean off the sticky residue..

Seems like a fine dehumidifier, but the instructions fail to explain the various modes. Fortunately, when I calIed the Consumer Services number I was able to speak to a human being. I wanted to attach a hose leading to a floor drain. She said that, if I press the Comfort button, the water will fill the bucket instead of draining into the floor drain. It also gives you a preset percentage of humidity. What I needed was Continuous mode, which kicks in when you manually set the percentage of humidity (using the + and - buttons)—it doesn't matter whether the Continuous button is pressed. Also, the number that you normally see on the display is the actual humidity level, not the one you set it to. 2/27 After using Continuous mode for a few days, I noticed that the LED display always said 30%—and if that's the actual humidity level, that's drier than needed, which means that the machine is using more energy and working harder than necessary. I called again to ask, Why, if I set the level to 40% (thereby invoking Continuous mode), the display always shows 30%. I didn't get a clear answer. The rep said that, if I don't want it that dry, I should switch to Comfort mode. But if Comfort mode means that the water fills the bucket instead of going to the floor drain, that's not what I want. The manual refers to "preset" humidity levels for both Comfort and Continuous mode, but she was not able to tell me what those levels are, except to say, "They range from 35% to 45 or 55%," that is, she didn't really know the answer. Further, if the levels are preset for Continuous mode, that means you can't actually set the level you want. My opinion of their documentation and their Consumer Services reps is at a new low. 5/11/25. I am taking away stars. The Midea dehumidfier worked well enough for two years. Then the defrost function quit. My plumber said that these days dehumidifiers tend to last only two or three years. This is just another example of planned obsolescence, loading the planet with waste.

Overall a good dehumidifier with a flaw that prevents it from getting a 5 star rating. It is a little bulky, but not so bad that it's too hard to move around, especially with the wheels. The Midea works pretty well at removing moisture from the air. Plug it in, set on auto, and it's good to go. The noise is very noticeable in any kind of living area, especially when Turbo mode is on. It's fine for a basement though. The built-in bucket can easily fill up in a day, so I opted for using a drain hose. This is where I knocked a star off. Firstly, for the price, they should include a drain hose. They don't, but any hose with a standard garden fitting will work. Secondly, even though a drain hose is attached, the bucket slowly fills up over the course of a week or so. When the bucket is full, the dehumidifier stops working until it is emptied so you have to check on it once in a while. I have two of these units, and both exhibit this flaw. Aside from this flaw, I like this dehumidifier. I don't know if I'd buy it again because of the bucket/hose issue though. I have a different brand of dehumidifier that also uses a hose to drain, and I never need to empty out the bucket on it. Update 09/2021: I still have two of these units running. They’re working great. Clean the filter once every couple of months and they’re good to go. Strangely, I haven’t had to empty the bucket in the last forever.

This has been a great dehumidifier. I got it in December of 2020, and it has worked like a charm to keep our semi-finished basement area (~1,584 sq ft.) super fine when it comes to moisture. This unit is the 50 pint model. I am not sure about its energy efficiency, but it seems fine to me. It is quiet, and has been maneuverable when I've moved it a little bit on a few occasions, but it has pretty much stayed in the same place. In the humid times here in North Carolina, I empty it every morning; it's full. But in cooler times in the fall and winter, it doesn't need emptying at all typically. I've thought about draining it via hose, but I've been fine with emptying it and replacing the water container each time. It's easy to remove the water container and replace it. I have done no maintenance on it. This unit has been most dependable, and I like the solid feel it has about it. Knowing what my experience has been at this point I'd buy it again in a heartbeat.

My air conditioner broke down in murderous Florida heat and humidity, and the mfg told me the part would take a month to get. I was concerned about mold/mildew when my 2400-square-foot home's thermostat pushed above 90, so I ordered this dehumidifier after researching different makes and models. It performed extremely well, quickly bringing interior humidity down to 50% (based on my setting), eliminating the mold/mildew threat. The amount of moisture it sucked from the air was astounding. The unit was going to be left running for a month because I was going away for a vacation. I had expected to have a friend stop in to empty the water reservoir perhaps once a week. However, the amount of moisture the Midea sucked from the air was enough to fill up the half-gallon receptacle twice a day, Fortunately, the unit's gravity drainage system worked beautifully. I hooked up an ordinary garden hose so that the water drained into a shower stall. Thus, it was able to run unmonitored the whole time I was gone. By that time, my air conditioner as fixed. This is a great appliance, and I would recommend it to aanyone who needs reliable, efficient dehumidification.

I am so glad I made this purchase. I was hesitant When shopping because it's a chunk of change to spend and I wanted to make sure I got a good quality product. So glad I went with this one. It does the job and I'm amazed at how much water fills up when it pulls the moisture out of the air. I live in Texas and a few months out of the year when the humidity is higher this has saved the day. My mom has COPD and this has helped a lot with air quality and her breathing. It makes my other household appliances run more efficient by controlling the moisture and the house feels so much better. Because it pulls the moisture out of the air I think it also helps with the actual house as well. I try to keep things well ventilated but in high humidity when I have to keep Windows shut this really saves our house from the walls getting sticky and any moisture buildup. Easy to use functions. It will beep a few times and automatically shut off once the water has filled up so no spills. I empty the compartment when I'm ready and pop it back in and it turns back on. When you turn it on it will show you the humidity level in your room and it shows you as the humidity level goes down. I put it on the Comfort setting and it regulates perfectly. It must be energy-efficient because I have not noticed any increase in my utility bill. I have used it on and off for several months now and no issues. It's on rollers so it can easily be moved into different rooms. I haven't had to do that I just put it in the biggest open room and let it do its thing and it seems to cover my whole 1800 square foot house. When I first got it I moved it into two different big areas of the house to nip it in the bud and now I've been able to keep it and one bigger open area and the air in the house feels great. It does have some noise to it when it's running but nothing intrusive and I find it soothing. The container at the bottom that fills up with water has a handle inside and the handle is very sturdy. I was extra cautious emptying it the first couple times because I didn't want any of the water to spill. The handle is very sturdy however and I emptied in the tub no problem. Once emptied, you slide in pop it right back in and it's good to go. You can set it to run on a timer or to stay at a certain moisture level. I don't leave it on 24 hours. There's really no need even in high humidity. I will run it part of the day usually letting it fill up a couple Cycles then leave it off at night. The water is secure when it fills up if it has to sit but I try to empty it right away. Although the water collected doesn't appear dirty I would definitely not recommend using it for drinking water for your pets or to water house plants. I either pour it in the tub or shower or I pour it outside for one of my trees or outdoor plants. Great buy , very pleased!!

This is my second Midea 4500 SF dehumidifier that I purchased. I bought my first Midea 4500 SF dehumidifier in 2022 and let it run continuously each spring, summer and fall up to the end of 2024. It worked flawlessly. I would turn it off periodically as needed so it could recycle. I cleaned its air filter each time the clean filter indicator lit up. I use the drain hose method to drain the water so I never need to empty the fill bucket. This spring, my 2022 purchased dehumidifier was not extracting water. That is the reason I bought a new replacement in 2025. The new one arrived at the end of June. I took it out of the box yesterday and let it sit on my level floor for 24 hours before use. I turned the new dehumidifier on this afternoon and it is working fantastic. I purchased the Asurion protection plan this time. I am looking forward to many years of great service from this model. It is much heavier than other dehumidifiers that I have purchased. However this model has been my most reliable dehumidifier purchased.
