I initially purchased this to help my potted indoor gardenia plant that’s on life support (I suspect I’m not meant to have one, they’re so finicky but I refuse to give up) but was so impressed by it I got one for my bedroom. Here’s what sets it apart from other humidifiers I’ve purchased in the past. First, it’s completely silent, and you can turn the display light off. So many of the tech gadgets I have involve noise or obnoxious LED lights on the control panels that leave my bedroom lit up like an air traffic control radar screen at night. Second, while you can control this manually on the unit itself, I like the convenience of being able to control the humidifier with my smartphone. I also like that you can schedule the days, times, and length of time you want the unit to come on. You can set the level of humidity you want, but It has an “Auto” option that when set will run until the room reaches a standard level of comfort. I’ve been using that feature exclusively and love it. The smartphone app also displays the current humidity of the room. Last but not least, most humidifiers advertise how easy they are to clean and fill. This unit is exceptionally easy to do both. While my gardenia may not survive, I’m glad I gave it a shot. The low humidity this time of year is rough. Running this for a few sporadic hours a day my skin is so much less dry and my hair is no longer standing on end with static.

I absolutely love this humidifier! The setup with both my phone and Alexa was incredibly simple—much easier than I expected. I didn’t think I’d use the smart features at first, but they’re so user-friendly that it’s now how I prefer to interact with the humidifier. Since I use my phone for everything else, it just feels natural. One of the standout features for me is how quiet it is. The size is perfect for my bedroom, and the ambient lighting adds a calming touch that I genuinely enjoy. What I love most is the ability to see the current humidity level in the room. It’s such a helpful feature and really lets you know how effective the humidifier is. After running it for just an hour, I could already feel the difference in the room. Over the last few nights, I’ve kept it running through the night, and I’ve been waking up refreshed and free of that dry-mouth feeling. However, I forgot to refill it last night, and this morning I woke up feeling like I’d spent the night in a desert—a testament to how well it works when it’s on! I also really appreciate the smart reminders for cleaning and refilling the water. It’s such a thoughtful touch that makes maintaining the unit hassle-free. If you’re looking for a humidifier that’s quiet, effective, and packed with smart features, this one is a fantastic choice!

I am sure glad I purchased a "Smart" humidifier......connecting to Dreo's app was seamless.....the app is chock full of options for both the operation and the monitoring of the humidifier.....yet comprehensive in the information contained in the app, it is easy to use and to monitor.......the humidifier itself is virtually silent.....the feature that is most attractive is the ambient light that changes from yellow to green to blue depending upon the humidity level the humidifier is reading, with yellow the lower humidity level and blue the highest humidity level.....very HIGHLY recommended.....

I want to address one question I had up front. I had posted a question here about whether humidity target levels could be set within the 5% standard range. I didn’t receive a satisfactory answer, so I installed the Dreo app on my phone, which was very easy to do. I connected almost immediately to the humidifier. And yes, you can set specific target percentages. I currently have mine set to 43%. Another question I had was if it was normal if the fan continued to run even when the target humidity had been reached and the misting ceased. Interestingly, no one has responded to that question, but the AI Rufus came up with the answer that it was normal, and indeed that is the case. The fan runs continuously even after target humidity levels have been reached. I had both questions because we run the device only in auto mode to allow it to kick in when necessary, and I noticed that the fan was running when the misting had stopped. I also found that in our bedroom, where it is used, setting it at 45% caused it to run excessively, but set at 40% allowed the humidity to drop too low. For us, 43% is the sweet spot but can only be accomplished through the app. The unit is of very good quality, light, and compact. It is perfect for a bedroom but not for a larger space. We use a larger capacity Levoit unit for our vaulted great room. The Dreo is also very easy to clean. That is extremely important as anyone who has had one that wasn’t as easy will understand. Mold will grow! We clean ours once a week and fill them with water from a Zero water filter pitcher. That or distilled water is vitally important. Anyone who has gas appliances - furnace, stove, fireplace - will see those flames turn yellow or orange. We did, and it cost us over $300 to have a gas valve unnecessarily replaced. I have read complaints from those who said that the unit runs dry quickly and stops working. If you live in a very dry climate, that is understandable, but we live in the mid-Atlantic and only use them in the winter. The auto mode is perfect as it only kicks in when necessary. For others, larger capacity units would be advisable; for us, using this in our bedroom, it is perfect. There have been no leaks; the units’ lights can be cut off with a tap and cut back on with a double tap. It’s virtually silent; I wouldn’t hear it if it were placed right at my bedside. At this price, I doubt you could do any better. I had not wanted to connect it to WiFi as I thought it was ridiculous to have a “smart” humidifier, but I really wanted to fine-tune the humidity target, which can only be done through that app. All in all, I would highly recommend this for smaller spaces(bedrooms, not great rooms or vaulted ceiling living rooms).

This Dreo Humidifier is absolutely the best. It works with Alexa, and the App is terrific! Very easy to clean, and the product puts out a good amount of mist with excellent coverage. It is a top fill, which is wonderful. The App allows you to adjust the auto feature, humidity level, mist power, or turn the unit off and on. You also can do this on the unit itself. I have owned many humidifiers, and this is the most efficient, attractive, and easiest product to clean and maintain. I highly recommend it.
