nice humidifier!

[This review was collected as part of a promotion.] this humidifier comes in a white shade and the tank is clear, so you can see how much water there is. it was really easy to set up; all i had to do was clean the tank and the demineralization cartridge, add water to the tank, and just turn it on. the mist comes out really finely and it distributes well through out the room. i used it during the night and my tank was still pretty full by the morning. the tank lit up blue when i turned it up since the humidity in my room was higher than 60%. the humidifier will display different colors depending on how humid your room is. the controls were easy to navigate; they had different settings for how strong you want the mist to come out. they also have a function where you can connect the humidifier to the dreo app, so you can control it via the app. overall, i think this humidifier worked great.

Quiet, simple, and makes the air feel better

[This review was collected as part of a promotion.] I’ve been using the Dreo Smart 4L Cool Mist Humidifier for a few weeks now & it’s made a noticeable difference in my bedroom. The air feels more comfortable, especially at night & I’ve woken up with less dryness in my nose and throat. The 4L tank is a big plus since I don’t have to refill it constantly. It runs super quietly, even on higher settings, which is great because I’m a light sleeper. It also looks sleek and doesn’t feel bulky or cheap. I did have a small leak once, but resetting the tank fixed it. Overall, it’s been very reliable and easy to use.

Great humidifier
on January 22, 2026

[This review was collected as part of a promotion.] I love how big the tank is and how easy it is to refill it. It does a great job at delivering moisture in my living room (the biggest room in my house), plus my plants loved the added humidity as well. The ultra fine mist makes it mess free-no moisture or residue left on furniture or floors. It's also very quiet if you plan on putting it in your bedroom, it has a nightlight, and also gives the option to add essential oils for a more relaxing aroma. I love this.

[This review was collected as part of a promotion.] The WiFi function on this product is definitely my favorite. I love having it as a controller. It’s a great sleek product I love the design of it. Not only that, it also works very well. I would definitely keep using this and recommend this to friends.

Modern Humidifier with all the Bells and Whistles!
on January 25, 2026
Posted by: stephanie529_1415
[This review was collected as part of a promotion.] This is perfect. So modern and convenient with its app abilities. I can control everything from the app. This allows me to change the humidifier settings without opening my baby’s bedroom door. The light is optional, which I appreciate. The set up took less than 10 minutes. One bonus feature is that this humidifier has a spot for essential oils!

Breathe smarter
on January 30, 2026
Posted by: tfields26_3236
[This review was collected as part of a promotion.] Setting up this Dreo humidifier was incredibly simple thanks to the clear instruction guide and seamless iPhone app integration. It’s awesome for our main living area and I switch at times to my daughter’s room also. The ultra-fine mist instantly tackles dryness, making the air feel crisp and clean.
I love the "smart" touch—the soft light actually changes color to signal the room's current humidity levels. It’s whisper-quiet and features a convenient essential oil tray tucked in the back for a spa-like vibe. Just a pro-tip make sure you use distilled water to keep the mist pure. It’s perfect for better sleep and healthy breathing.

Love the light on it, a pretty green color that looks cool in the dark. It instantly starts working, pouring out a refreshing cool mist that feels amazing. It also has an area to put in scented oils I can't wait to try out! Definitely recommend this product!
