Dreo Portable Air Conditioners, 12,000 BTU AC Unit for Bedroom with Drainage-free Cooling, 46dB Quiet, APP/Voice/Remote, 24h Timer with Fan & Dehumidifier, Smart Standing AC for Room Indoors, AC515S

I'm always skeptical of online reviews. But this unit earns and deserves its high ratings. Easy to set up, easy to operate. The app has worked flawlessly. The unit quickly cools the hot upstairs hallway and bedroom with ease. The dehumidify function works great, too. It's pretty humid here (ranging from 65-85%), and this thing makes a noticeable difference you can feel. As for noise, it's not bad at all. It is definitely quieter than a box fan, but a little more so than a white noise generator. But I typically have it on the highest fan speed. Lower speeds are quieter, of course. I also monitor our daily electric usage. We're in the middle of an unpleasant heat wave, so this is running quite a lot. I was surprised that it really hasn't added much to the electric usage. If you're on the fence about spending the money on a portable unit, this is worth the price. I'm pleased with it and would recommend it!UPDATE: Still very pleased with this unit. It did so well in our home that I decided to put this in my workshop and run the venting and drain through the wall. Works perfectly and is able to comfortably cool and decrease the humidity in my shop!

I have had this unit for around 11 months. It works great, and it's really quiet. The app works, the remote works, I've had to clean the filters a few times which was really easy. I do recommend getting the app so you can download firmware updates.I have had about 6 units and this is the best one I've ever had by far, which is surprising since it only has one tube for the exhaust.This is a safe buy. I use it in a medium sized bedroom but it ends up cooling most of the upstairs and that's with leaving a door open so my dog can use the patio at anytime. It's a really impressive unit.I have not noticed the outside air coming into the unit, as one reviewer states, I don't even think it's possible since it has just one tube that only blows in one direction. It's never created funky odors. Not sure why his outside air smells like wet dogs he should get that checked out.

PERFECT so far! I've had this for a few months. I'm using this in a small 12x12 upstairs, south-facing bedroom with no tree cover that becomes the hottest room in the house. I work nights so I also have heavy blackout curtains too and when our central A/C is sent at 68, this bedroom can be 74 or 75 according to a little room thermometer I have! And that's way too hot for me. The room has one tiny vent for the home's central air that is worthless, so I needed more cooling, so a unit like this was my best option.The hookup was simple with the necessary items to install the hose into the window. I did it with a very non-handy friend of mine so it was very easy, and its working great! I have a thermometer in the room and can tell easily its working. My thermometer also tells me the humidity in the room and the A/C obviously reduces that too.***I am not using the removable water tray or dehumidifier function on this A/C unit because its not necessary unless the room humidity is around 85% - (like maybe a hot garage or something may be), this bedroom seems to usually stay around 50% humidity since there is SOME air conditioning from the home's central air system. I'm betting if this was in a home without central air, you may go ahead and turn that dehumidifier function on, but I do not.The remote is a great feature, or I also downloaded the app but usually I just use the remote. Either is simple and both work fine.Its only the end of May, so the real test will be July and August, but so far, its making my bedroom cool to sleep comfortably. If there are any problems later in the dead of summer, I'll update. If not, I won't and this review will stand.This is an excellent unit, and great looking in the black, at a great price. Best purchase I've made in years!!! Anything that helps us sleep better is worth its weight in gold for sure!

Great Product. Works Great and have had zero issues. Easy to use and blasts cold air. After 6 to 8 weeks, I still have not needed to empty any water from it.

The A/C unit arrived yesterday. It was a little on the heavy side but I was able to pick it up and bring it inside, just lift with your legs and not your back.The unit was packaged well and nothing was damaged. It took me about 30mins to set up the window insert and another 5-10 mins to plug it in, download the app, and setup an account. I didn't use the adhesive insulation as there wasn't the need. I cut triple strips of the non-adhesive insulation for each of the four sides around the window. Once I placed the insert into the open window, I closed the window and held it down using additional force to seal the area. Next, I put the window locks I purchased separately on each side of the window frame. The locks held the window down tight and I then removed my hand from the window. This provided a tight seal around the insert.Next, I attached the exhaust tube after extending it slightly (Keep unit close as possible to the window. Placing the unit on a stand to elevate it will help). I ordered an insulation sleeve for the exhaust tube as recommended.Finally, I plugged the power cord into an outlet and turned the unit on. Ice cold air immediately flowed from the unit, putting a smile on my face, my wife's face, and our German shepherd "Rick James' " face.We had our home built in 2013, so it's a fairly new home. Unfortunately, the U-shapped design of the home makes master bedroom difficult to cool in the way too hot summers here in Boise, Idaho. My wife and I are cold weather people and anything over 70 degrees outside is too hot. We keep our house at 57-59 degrees in the fall and winter as this is the temperature we like. During the summer, we try to keep the house at 65 degrees. However, the master bedroom feels like a sauna. This is the reason we purchased this unit. Well, we slept like babies last night! The unit kept our bedroom at a cool 63 degrees all night. The unit is quiet, intuitive, sleek, and modern. I recommend this product so far.
