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!

Play Video With the cold weather recently, I’ve been running my heat almost constantly, which created a very dry environment in my home. My usual humidity level of 40–45% dropped to 22%, so I decided it was time to get a humidifier. Since I’ve had good experiences with Dreo products before, I chose one of theirs, and it has been a solid choice. The build quality is great, and I appreciate the slim profile. The adjustable mist direction is especially useful, as it allows me to place the humidifier closer to the wall and direct the mist away, which saves space. The lighting effects are a nice touch and make it easy to see the current humidity level at a glance. If needed, they can also be turned off, which is a feature I appreciate. One standout feature for me is the ability to set a specific humidity percentage. Once it reaches that level, the humidifier adjusts itself to maintain it. This makes it much easier to use without worrying about the room becoming too humid. The Alexa integration is also helpful, especially for adjusting the settings without having to get up. Overall, this humidifier has been a great addition to my home. It’s well-designed, effective, and has features that make it easy to use daily.

Love this humidifier! The app is easy to use and allows me to set a schedule which is super convenient. I also like how easy it is to clean compared to other humidifiers I’ve used. The quality is wonderful. I wish there was a less bright option for brightness. The noise is nonexistent and the size is perfect for a bedroom!

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 humidifier is amazing. It's quiet, has a nozzle on the top to divert the angle, changes colors to indicate when the air is dry, comfortable and wet. It was really easy to connect to my phone for easy remote control, has a night mode but also isn't overly bright if you want to use it as a night light, and was easy to fill with water. It will also be easy to clean when I need too. It's not too big so it won't take up alot of space and it seems well made.

I’m really pleased with the REO Smart Humidifier for my bedroom. It’s incredibly quiet, making it perfect for a peaceful night’s sleep. The top-fill design is super convenient, and the 4L capacity ensures long-lasting moisture without constant refills. I also love the built-in nightlight feature, which adds a soft, calming glow. Overall, it’s simple to use, efficient, and does exactly what it promises—highly recommended!

Been using this humidifier for a while now, its great no more nose bleeds from. Definitely the best humidifier i have ever had - holds a ton of water and is really easy to clean. The application works great, you can set the working time, low noise level, bonus the light orange, green, blue that you can keep it during the night. Tina from Customer service was very helpful after a small problem that I have. Thank you Tina.
