DreoSmart Humidifiers for Bedroom, Top Fill 4L Supersized Cool Mist Humidifier with Nightlight, 36H Runtime, Touch/APP/Voice Control, 28 dB Quiet Ultrasonic Humidifiers for Large Room, Baby, Plants

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).

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!
