## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Humidifier – Smart, Quiet, and Efficient!
*by S***D on June 30, 2025*

The Dreo Smart Humidifier has been a fantastic addition to our home. It’s super easy to use, and the smart features like app control and scheduling make it incredibly convenient. I love how quietly it runs—you barely notice it’s on, but the difference in air quality is clear. The large tank lasts through the night, and the mist output is strong but well-balanced. It also looks sleek and modern, blending in nicely with our room decor. Highly recommended for anyone looking to maintain comfortable humidity levels with minimal effort!

### ⭐⭐⭐⭐⭐ Works Extremely Well - Easiest unit To Clean By Far - Certain Functions Only Available With The App
*by J***S on December 14, 2024*

This is an update to my previous review. I have another brand of humidifier as well, a Levoit, which is very effective, but in terms of ease of cleaning, the Dreo is superior. The Levoit has a lot of nooks and crannies with lots of right-angled corners, making it quite tedious to get to all the mold that develops over time. The Dreo has very few such corners and crannies, making it far easier to clean. Also, as a result, it just stays free from mold for a much longer time. I clean them on a weekly basis but find very little that needs to be cleaned on the Dreo, but a lot of areas that have developed black mold spots on the Levoit.Previous review: 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 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. I was contacted by someone from Dreo support and told that the fan runs continuously to help spread additional moisture even when not misting and also to give a reliable humidity level reading as it draws in ambient air even when not misting. The fan is virtually silent and you wouldn’t know it was running unless you put your hand right over the outlet.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, if using tap water. 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).
