Great humidifier
I bought these to use for my house plants. I love that I can set a humidity percentage through the app and the humidifier will maintain that humidity level. If the humidifier runs out of water it automatically shuts off and sends you a notification through the app. This unit is silent as far as I am concerned, the mist is very fine and is working well for my plants. I like that the unobtrusive lights in it (which can be turned off) let’s me know if my current humidity near the humidifier is in its target range (green) or if it’s dry (below target humidity, yellow/orange) or wet (above target humidity, blue). You can use the app to turn the device on/off and to adjust the humidity, this is also where you control whether the humidity indicator light is on or off. I recommend it highly, I am considering getting the size up to be able to cover more of my room space. This unit holds a full gallon of distilled water when filled from totally empty, if filling from auto-shutoff it will take slightly less than a gallon. They manufacturer recommends using distilled water to avoid lime scale as do I. We have very hard well water and uso g distilled has saved us from having to descale.

Absolutely amazing for the price
I have an extremely large room, so it struggles a little bit to keep the humidity at a certain level, but outside of that, this thing runs so quiet, and is absolutely amazing! You can set schedules or saturation points, and it works with Google home voice commands. It’s a great addition for Michigan winter times. It’s a super easy setup and I was extremely surprised on how well the mobile app is to set up and how refined the graphical interface is.

Fantastic job!
I absolutely love this! It’s the perfect size and the quality is great! There really isn’t any noise to complain about. It has helped make the air less dry in our home.

Good performance, but misleading warranty registration
I use this unit in my bedroom (about 12×10) with a small 3/4 bathroom attached, and it’s been effective for that space. Humidity levels stay comfortable without the room feeling damp.It integrates seamlessly with Google for voice control and has been reliable. It likely works with Alexa as well, but I don’t use that system, so I can’t say for sure.I’ve been using the unit for just under a month and run it regularly. To avoid scale buildup, I use nursery water, and so far the unit has stayed clean. There’s a cleaning reminder after 100 runtime hours—when it went off, I took the unit apart, rinsed it, and let it dry, and it wasn’t very dirty. The app allows you to adjust the cleaning reminder, and I set mine to 300 hours.The reason for removing one star is the warranty issue. The box advertises an extended 30-month warranty if you register using the QR code, but in both of my registrations (this humidifier and a Dreo fan), the system only applied a 12-month warranty. When I replied to the confirmation emails showing the incorrect warranty, support responded with the same explanation both times:“Due to a recent upgrade to our warranty extension system, there was a temporary issue that caused some extended warranty periods to display incorrectly.”Support did correct the warranty after I contacted them each time, but this appears to be a recurring issue. It feels like the process relies on customers not noticing the incorrect warranty being applied.Aside from that, the product itself performs well. Fix the warranty registration process and this would easily be a 5-star product.

Love IT!
This is a great humidifier! I loved it so much I got another for another room. No smell, very quiet, easy to use and connecting to the app makes it a breeze. I love all of the settings to make sure things are set to our comfort. It is so easy to set up, fill, and get going. The longest part of set up was just downloading the app.

Space saving and durable humidifier!
Great humidifier! I researched and this one was #3 on a list out of a rating. I am impressed at the functions and durable nature. It s easy to operate and fill with distilled water. It is great in my bedroom and I like the features as it has an app to dowload for additional features.

Good value
A good choice. It works well and has a good sized water reservoir. Only uses about half the water overnight. Has 3 mist settings. Very quiet. You can turn off the nightlight. You can direct mist away from the wall but the amount you can change the direction is fairly limited. Seems sturdy and a good value for the price.

A Game-Changer in Home Comfort: The Dreo Humidifier
As an avid enthusiast of home technology, I’ve tested a wide range of humidifiers over the years—but none quite measure up to the Dreo Humidifier. In fact, this is my second purchase from the brand, and I couldn’t be more impressed. Dreo has truly raised the bar when it comes to combining design, functionality, and user experience.First, let’s talk about aesthetics. This humidifier is an absolute masterpiece, featuring sleek, modern lines that effortlessly blend into any home or office decor. It’s the perfect fusion of form and function—quiet, unobtrusive, yet undeniably stylish. Whether placed in your living room or bedroom, it adds a touch of elegance without drawing unnecessary attention.Performance? Top-notch. Unlike many other models, the Dreo Humidifier operates virtually silently, ensuring a peaceful, undisturbed environment—ideal for a restful night’s sleep or focused workday. Its engineering is simply flawless, providing consistent humidity levels without any annoying whirring or clunky operation.But what truly sets Dreo apart is the level of customer service. When I reached out with a simple query, their support team responded quickly and with complete professionalism. It’s clear that the company values customer satisfaction as much as the quality of their products.In summary, the Dreo Humidifier isn’t just a purchase—it’s an investment in better living. Whether you’re a design aficionado or a tech-savvy consumer, this humidifier delivers on every front. Trust me, you can’t go wrong with a Dreo. Highly recommended.

This works really well. I have it in my living room and its handy. Since I have a bigger room, I set the humidity higher and that works. The app is really useful, i dont need to go to the device to check things. Its also quite easy to clean since it can be separated into 3 parts. You can also remove the indicator inside to fully clean it. It has a sleek design as well. I was just hoping they also sell this in white. If they would, I would buy another of it.

Best humidifier for bedroom I’ve ever owned. Makes no sound whatsoever. Like not one single gurgle. Easy to clean. Phone app is user friendly, great features like sleep mode, automatic shut off and timer. The lighting can be turned on/off- also controllable on the app.

I recently purchased the Dreo Smart Humidifier, and I’m quite pleased with its performance. Here are my key takeaways:1. **Easy Setup**: The humidifier was straightforward to set up right out of the box. The process took only a few minutes, making it user-friendly for anyone.2. **Water Requirements**: It’s important to note that the Dreo humidifier operates best with distilled water. I’ve been using Winstons ARION Distilled Water (100% Pure Steam Distilled Water, 5 Litres by UINCLU), which has proven effective in maintaining optimal performance.3. **Cleaning and Maintenance**: For continued efficiency and quality, it’s essential to clean the unit and change the water every 100 hours. This routine maintenance ensures the humidifier functions properly and delivers the best results.4. **Improved Air Quality**: The humidifier has significantly improved the air quality in our bedroom. Our room’s humidity level was around 32%, which is quite dry. With the Dreo humidifier, we’ve been able to increase it to the recommended 45%-50%.5. **Relief for My Son**: Most importantly, the humidifier has benefited my 4-month-old son, who previously struggled to breathe comfortably at night. The increase in humidity has alleviated his nighttime breathing issues, making for more peaceful sleep.6. **Design and Features**: The humidifier has a modern design and is relatively quiet, which is crucial for use during the night. The additional smart features, like scheduling and adjustable mist levels, add to its convenience.In conclusion, the Dreo Smart Humidifier is a reliable solution for improving bedroom humidity. With proper maintenance and the right water, it has proven invaluable for our family, especially for my young son. I highly recommend it for anyone dealing with dry air issues.
