I’m one of those people who purchase items at Amazon and only realize later I have to make another trip to the UPS Store.FINALLY a GREAT product that will not be going to the return bin. The humidifier is beautifully designed. What? A plain old humidifier beautifully designed? Yes!There is the base, the tank and a cover. However, the large center column that pushes out the water is backlit and changes colors depending on amount of humidity in the room. Three different colors show dry, comfortable and wet. I’m sitting in the bedroom looking at this unit and I find sometimes I just stare at it. The water shoots up the column out the top but since it’s backlit you see bubbles in the water and with the light it’s sort of looking at the bubbles in a fish tank. Am I weird that I find the reverse waterfall captivating? I guess I am because just looking at the tank is very relaxing,(yes really!)There are so many things I like about this unit that to list them all now would take three pages.As far as controlling the unit, DREO has its own app that you use to totally control the humidifier: level of humidity, beep sound on/off, turn front LED display on/off, auto/manual and level of mist entering a room. The app does pretty much everything you want to activate all the controls. If you are sensitive about noise in a bedroom when you are trying to sleep, I can honestly say that the unit is extremely quiet. As I stated, if lights or noise disturb you at night, you are able to turn off front display, light in center console and switch it to totally auto control without having to worry about adjusting air flow or amount of humidity. All you have to do is press sleep mode on the app itself.On top of all this you’re able to control the humidity with Alexa so you don’t even have to get out of bed.It’s not very often that I rave about a product for sale on Amazon, however this appears to be an almost perfect appliance with a great app. Oh yes, app was very easy to set up and guides you through every step including linking it with Alexa. Is this a perfect find? Could be however I’ll update this review after I’ve used it for a while but as of now I don’t foresee any problems!UPDATE: 3/2/2025As a former engineer I am very selective about the products I purchase, and now sure enough I have a gripe!I’ve found that while utilizing Alexa you are unable to ask to change humidity level. I said “Alexa increase humidity level” but it did not respond. Sort of like a lot of guys talking to their wives! I’ve also discovered that in auto mode it defaults to a very low output which was not effective to increase the humidity in my master bedroom. Funny that it’s called a MASTER bedroom because the dog runs the house and not me!!

I had a humidifier for many years before buying this one. The previous one was so bad, I'm actually amazing I used it for so long. It was a bottom fill and was very hard to clean, more like impossible, parts of the humidifier you couldn't get to so it just started growing bacterial. The opening on the bottom to add water was extremely loud and hard to twist, too.I stumbled on this Dreo brand and I've had it for over a month and a half now and used it everyday since I got it. It is always on and automatically sensing. I will admit, when I first started using it it was leaking quite a bit... and I was trying to figure out why it was leaking and I'm pretty sure it was because there was not enough air flow on the bottom of the device. So the timeline of the leaking, I bought it for about a week it was leaking and leaking and during that week I was trying to figure out why and then since after figuring it out it has never leaked again, I just keep it elevated so airflow can pass on the bottom. I put mine on top of 4 coasters, two on either ends of the humidifier and it no longer leaks!I clean the humidifier every 200 hours when it notifies my the 200 hours are up, there's about 8 different pieces this humidifier has that I need to clean which I actually like because the more I can clean the less likely it will mold and grow bacterial. I know lots of people complain that there's a lot of pieces to clean but if you think about it, this humidifier you can reach every part of the humidifier so if you just keep everything clean the thing could last forever, assuming the electrical side of the humidifier never breaks.It is also extremely quiet, so quiet I bet you probably can't even hear it. I like that the light can be turned on or off, I turn it on during the day to see what the humidity level is and turn it off during the night as I want darkness while sleeping. The angle of where to route the air is nice, I just wish I could angle it a bit more, like maybe 20 or 25 degrees but I still like it! I always have it angled forward. Another thing I really like about this humidifier is I can actually put essential oils in it so it puffs good smelling stuff into my air (just put the essential oils on the pad that pops out on the bottom back). I also really like how nice it looks, I bought the white color and it looks pretty sleek in my opinion, not some ugly thing sitting somewhere. The build quality seems very good too! I'm planning on buying the next size up of this humidifier as I love this so much!
