Happy that know more skin and nasal
The DREO is very well made and easy to use. I particularly like the color mode options, controls are simple a easy to use. It's whisper quite, and looks great. The price was great and it's very good quality. Well worth it and it, works great. Compared to the other Humidifiers I picked this one because of the ratings n reviews, I really like that it has a large tank then the other. It was a good choice

A cute nightlight and humidifier with a huge tank!
Fantastic humidifier for keeping a living room very humid. I call myself a bit of a froggy lady I like a humid and cool room. This humidifier will last over night maybe even longer on a full tank. The tank is quite large. You can fit it on a little side table for a cute night light even. I love the blue color it helps me sleep at night because I feel so safe with it on. I originally bought this for my cat with asthma who unfortunately passed away but it was a great deal for only $30 you can’t beat it. I’ve had it for several months and it’s pretty easy to clean you just pop open the tank and wipe it out with a moist towel or paper cloth. The top will collect dust around the edge so you have to wipe that part too. Eventually some strange red residue will collect inside the tank so wipe it out after every use. This humidifier is easy to understand the settings you only have to press a touch button. There is no physical button but a touch sensitive button. I think the functionality is probably good for old people who don’t understand technology. There’s no noise at all I sleep very fine with it on. My old humidifier makes a lot of noise when the water lowers and it’s a Honeywell a name brand. So this is much cheaper and a better value for your money. Better even than the leading brand.

Wonderful Humidifier
This item is easy to use and very quiet. Also, it works very well. It is small, so if used every night, it must filled daily. We love it. It has a strong mist output, even on the medium setting. Also, I love that you can use essential oils with it.

Bothers my dog for some reason
I have been happy with this humidifier. It's very quiet, compact, and increased the humidity in my bedroom. It has a long runtime, a cool light that you can adjust or turn off, and it shuts itself off if it runs out of water. However... The last few nights my dog has been really restless and wanting to go outside multiple times during the night. I thought he was having bathroom issues but he would just go out there and sit there, refusing to come back in. Once I did get him in, he started trembling like he was scared. The only thing that had changed was this humidifier, so I shut it off. After that he calmed right down and was fine. He's very sensitive to any sort of beeping but there was nothing I could hear. Not sure if he was hearing something. Just a weird thing to mention if you have a sensitive pup.

Great humidifier
Works perfectly. Looks great especially with blue light on. Never owned a humidifier before. I feel so much better with this on. No runny nose or other breathing problems. Sleep much better. I hate that I have to keep buying mineral water but it’s worth it. Very quiet and easy to set up and clean

Quiet and good humidiier
I like the look of the humidifier and it runs very quiet. I barely know it's on, even when it's running at the highest 3-bar setting. I like the cool blue light in it with water effects seen thru it. The size is perfect and it's a good value for the money. Easy to take apart to clean. Just lift the water tank off. A simple humidifier that looks cool. Recommended.

Cleanest humidifier ever!
Quick Take: This is the first humidifier I’ve owned that doesn’t get grimy or dirty inside. It works extremely well and is very well designed — I’m only returning it because the size is larger than what I personally need. Performance & Cleanliness: What stood out immediately is how clean this humidifier stays. No buildup, no slime, no hard-to-clean residue like I’ve had with others. The mist output is strong and consistent, and it noticeably improved the air quality. Ease of Use: • Easy top-fill design • Simple to clean and maintain • Quiet enough for sleeping It feels thoughtfully designed compared to cheaper models. Size Consideration: The tank is large, which is great if you want fewer refills or need to humidify a bigger room. For my space, it’s just more capacity than I need, so I’m downsizing. Bottom Line: If you want a large, clean, low-maintenance humidifier, this is an excellent choice. I’m only returning it due to size — not performance or quality.

Great humidifier! Compact and easy to use.
This is now my 3rd Dreo product and I've been happy with each one (Other 2 are fans) . This humidifier is compact and easy to use. Not too big and not too small. Design looks good and looks nice with the blue light on. Its also simple to add water and clean the product inside. Add your favorite essential oil and its very cool and nice. I use organic peppermint and I feel like I can breath more. Your room will also smell nice with the right oil. The only downside is that I feel like the tray for adding essential oil is too small and is located in a very inconvient area of the humidifier. Its a bit hard to press and take out the tray if you have big hands. It would be nice if it was on the front side and located above the buttons area.
