    • Happy with it
I have owned four Midea dehumidifiers prior to this one. This is my favorite so far. It has a small bucket, so I recommend this model for people who plan to use the drain or pump feature in order to avoid emptying the bucket frequently. As a refurbished unit, it is a pretty good value for one with the pump feature. No auto-defrost but from what I understand that feature is only necessary if you are operating the dehumidifier in an area that is below 60 degrees (which does not apply to me). The main improvement on this model vs other ones is the noise -- the fan is certainly noticeable at 57 decibels, but at least it is consistent. Previous models that I have had would make a variety of clunking, droning, and fan noises as the fan, compressor, and/or pump kicked in. If it's in your living room, all these different noises can get pretty distracting after a while. The manufacturer seems to have solved that issue with this model -- the main noise is from the fan, which is either on or off. I really appreciate this improvement because I have it running 24-7 in my living space with the pump activated. It does have a quirk where it cuts off at the target humidity level, then the humidity number starts to count up to around 62 and then it turns on again and the number drops immediately. My room humidity obviously did not increase that much in a three minutes, so I think it has to do with the location of the sensor. Bad design maybe but the point is that it successfully keeps my living space between 45 and 50 percent humidity, which is my target so I just ignore the number on the machine. I use the SmartHome app and like it -- you can check the humidity level and turn the unit and pump on and off. Lastly I would say that this dehumidifier is a relatively compact, lightweight and attractive unit compared to others than I have owned. It sits fairly low to the ground and is not intrusive visually. Hopefully it will be durable -- I will lower my review if it breaks in what I would consider an unreasonable amount of time. ... show more

    • Great for the price
Wife was looking for a dehumidifier that wasn’t going to be ridiculous in price for what we need. Gave this a one a try and it does really well. It’s quiet, what you hear is a very light fan noise if you’re in a completely quiet room. It does push out warm air. Size of the tank is nice but also has a tube that is connected to also push out water so you don’t have to worry about it getting full. The size big, almost a door frame long but it’s nice and easy to use. Controls the humidity really well and we are satisfied. The only thing I’d say is when moving it don’t tip it over or let a toddler push it over, otherwise have a lot of towels ready. ... show more

    • Great so far
The 50 pt unit is a BEAST. Check the dimensions to make sure you know what you're getting. It's hefty too. Seems heavier than its listed weight but glad it seems durable. As for me, I had a recent roof leak and a landlord that's content to leave the ceiling saturated after a repair. Got the 50 pt refurbished model and it's been great at removing the moisture and smell from the house. It has an ozone/ion feature which is great, but I recommend only using it when not home or when in a different room. Ion generators are not really healthy to be around, I'd recommend googling it if that's news to you. Overall, it seems to work really well. I like the pump. Setting it for a humidity level seems to work well, but I have experience with humidity sensors, they can be really wonky so I don't expect 100% accuracy with anything with a humidity sensor. My favorite thing about this so far is that you can control with your phone BUT you can do it over the local network. I had to use and sign up on the android app to get it on my wifi, but once I did I was able to integrate this into home assistant and turn off internet access on the router for the humidifier. I hate giving 'smart' devices free reign on my network and access to the open internet, so I love that I can restrict access and yet still control w/ my phone, and stuff. Kudos to Midea. That's pretty rare. By the way, I thought this was missing the wheels when I bought it but they were inside the water tank. I didn't notice until I went to empty it for the first time. Much easier rolling this monster around than carrying it. ... show more

    • Complete garbage
A brick would have worked better and used less energy. This was “refurbished” but I’m not sure anyone tested it. Awful product.

    • So far so good
It works as expected. It’s a refurbished unit, so there are a few surface scuffs, but nothing that affects how it runs. The design’s clean and everything works exactly as it should. The setup was quick and easy, and the app lets you control it remotely without a hitch. It’s a bit loud, but if you’re using it in a basement or garage, it’s not a big issue . Considering that it’s a refurbished unit, it could be a little bit cheaper. ... show more
