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!

I bought the Dreo AC515S for my bedroom, and I’m seriously impressed. It cools the room down fast even during hot summer nights and does it quietly enough that I can still sleep soundly.The setup was simple, and the window kit fit snugly with good insulation. I love the sleek design it doesn't feel bulky or intrusive in the room. The remote is magnetic (genius!) and the smart app lets me adjust settings from bed or schedule it to turn on before I get home.One of the best features? No water bucket to empty it takes care of the moisture on its own while cooling.Overall, this Dreo AC has made my bedroom way more comfortable without the noise or hassle of other units I’ve tried. If you’re looking for a quiet, efficient, and smart portable AC for your bedroom, this is it.I also ended up buying a second one for my son's bedroom as well.
