Q: Is there a sleep mode? Can the lights be shut off?
submitted by C - 1 year ago
A: Yes, the lights can be shut off. But there is no specific "sleep mode" function.
submitted byMaryam - 1 year agoA: Does it use a Filter?
submitted byMambo320 - 1 month agoA: If using the app, you can set a specific schedule for the device including days and specific times to turn on and turn off. So essentially that could be your sleep mode scheduling. On the base and app, you can turn on and off the light.

Q: What's the difference between this model and the 311s?
submitted by C - 8 days ago
A: The main difference between this model and the 311s lies in their appearance. Their functionalities are quite similar, and they also have the same water tank capacity.

Q: Does it come with a cartridge?

Q: Does the essential oil slide in pocket push back in fully. Mine doesn’t click at all when it is closed and seems like it is not engaged in a lock position- it rests in pocket and it doesn’t take much effort to pull it out. I don’t want it to fall out.
submitted by tellsthetruth42 - 1 month ago
A: The essential oil tray is designed with a spring mechanism. If you find that it can be easily pulled out and does not seem to lock securely in place, please contact Dreo customer support. We will be happy to assist you further to ensure your device is functioning properly.

Q: Do i need to purchase a filter?
submitted by Joice - 1 month ago
A: If you use purified water or water that has been boiled and cooled, you do not need to purchase a filter. However, if you prefer to use tap water, we recommend purchasing a demineralization filter to help reduce mineral buildup and keep your device running smoothly.
submitted byDreo - 13 days agoBrand expert
Q: can you operate it without using your smart phone.
submitted by Tom - 11 months ago
A: Yes. Most functions of the humidifier can be operated without using the app. However, the schedule function cannot be directly set on the machine.

Q: Does this have a cancer warning
submitted by Cruz - 11 months ago
A: Yes. We would like to emphasize that Proposition 65 warnings can be found on various electrical products sold in California, as the law encompasses a wide range of trace elements. It is worth noting that general power cord plugs may contain lead, and we advise avoiding direct contact with metal plugs while using the product. However, it is challenging to completely eliminate contact with trace elements, as indicated by the California warning. Rest assured that we comply with the regulations of California's Proposition 65 and have included the necessary warning on our product packaging to ensure transparency and compliance.

Q: Is this an Essential oil diffuser and an air humidifier???
submitted by Jairo - 1 year ago
A: This is a cool mist humidifier, with the option to add essential oils to a pad that slides into the base. You should not add oils to the water tank. The pad mentioned in the base is a simple push button to pop oit

An advanced humidifier with an easy to use app
[This review was collected as part of a promotion.] This is the most advanced humidifier I’ve tried, though it has been awhile since I last used one. The set up was very easy, just removing some tape and cardboard, opening the filter, and filling the tank with water. The app was also fast and easy to set up: after setting up an account and connecting to WiFi, the humidifier was up and running. It is a very quiet machine, which is great in case I use it while I sleep. It seems very durable also, light but sturdy and easy to move.

Cool mist humidifier
[This review was collected as part of a promotion.] The DREO Smart 4L Cool Mist Humidifier has been working very well in my home. The assembly process was straightforward and easy to complete right out of the box. I've found that the app control works smoothly and track humidity levels. I like that it provides consistent moisture for an extended period without requiring frequent refills. This humidifier is not too heavy and cleaning it is simple as well.

Amazing humidifier !
[This review was collected as part of a promotion.] Absolutely love this humidifier , it’s a game changer for the dry seasons ! I usually have a sore throat all winter long but not anymore ! What I love the most is the amount of water the humidifer can hold AND everything can be seen through the app You can check the currently humidity level , and the differences in the room . There’s an auto option to set a desired humidity for the room which is really nice , I personally keep it around 45% humidity and it makes a huge difference in the morning It also lets you know when to clean the tank out and how much filter life is left . It’s nice because bacteria can build up and it’s easy to forget to clean something like a humidifier .

Nice Quality
My husband bought this when I was sick and was all stuffed up. It fits nicely on my nightstand. It’s small and quiet. The app is nice too. Worth the price.

Works Great & Has a Great App!
[This review was collected as part of a promotion.] Okay I honestly love this humidifier! My husband and I have been wanting to try out a humidifier because sometimes we both wake up with a dry mouth or dry nose - and as far as humidifiers go, this one seems great! It obviously functions great, and has lots of manual settings where you can set it to run all the time at 3 different most levels, or you can set a target humidity so it will kick on and off through out the day or night to target the humidity you set. You can also download an app which is SUPER easy to use, and you can turn it on or off, and adjust the setting or the time schedule it operates on all from the app! We have loved this product and will continue to use it every night! We have noticed a difference in our sleep too, when we wake up in the morning now we don’t have as dry of throats or noses anymore, which has been great!

Works amazing
[This review was collected as part of a promotion.] I previously had another cool must humidifier and it would make everything in its surroundings wet. So I was hesitant to try this out but I’m so glad I did. The mist is strong but does not leave a wet residue on anything. I love that it tells the humidity amount and you can easily control it from your phone

Great Humidifier w Great App!
[This review was collected as part of a promotion.] This humidifier is pretty awesome! Our family has been sick and its been getting us through this dry, cold flu Season. The app has been so great. It was pretty easy to set up. You can set different colors or turn the light off. It also has color indicators to tell you whether the air is dry, comfortable, or wet. You can control the percentage of moisture you want the humidifier to reach. Finally, you can turn the humidifier on or off through the app. Finally, it has an option to add aroma cartridges which you can buy straight from the app, which also shows any other items that you could purchase with your model. Overall, we love our humidifier!

Excellent humidifier, fully met my expectations
[This review was collected as part of a promotion.] We’ve been using the DREO Smart 4L Cool Mist Humidifier for a while now and are very happy with it. The large 4-liter tank lasts almost all day and night, so there’s no need to refill it frequently. It humidifies the room evenly, and the mist is very fine — no water buildup around the unit. It operates very quietly, making it perfect for a bedroom or nursery. I really like that it can be controlled via the app, which makes it easy to set the desired humidity level and monitor it in real time. The design is modern and stylish, blending well with the interior. I also appreciate the aromatherapy feature — it creates a calm and pleasant atmosphere. Overall, this is a high-quality, smart, and well-designed humidifier. Highly recommended 👍

Love it
[This review was collected as part of a promotion.] Received complimentary from influencer for an honest review . This item took me 40 mins to set up . Water kept leaking out each time I filled it up and placed on the base . The spring had came out along with water stopper . Once figured out and set up this item is very good , auto pairs with phone and also can be used with Alexa and Google voice . Changes colors , not so on the quiet side I can hear it . A bit of a space taker as it it huge as you can see how much space it is taking up on night stand . Has a section to add and use with essential oils . Also the filter seems to be cleanable and reusable. Over all other then the hard set up experience o had this is a good humidifier and worth it .

Comfort at the touch of an app
[This review was collected as part of a promotion.] I received this from Influenster in exchange for my honest review. The Dreo cool mist humidifier is a wonderful addition to our house. It is controlled either via smart phone or by pressing controls on panel. The smart feature allows for an array of set ups such as timed, on and off. Automatic by humidity level that you set. Colors to set the ambiance or to indicate the humidity levels can also be set via the app on your phone. It has 3 levels of mist that you can also contol along with a directional vent. It comes with a filter and you can monitor when to replace it on the app. The set up was easy and we love the colors now in the room that comes with the knowledge this winter will be a comfortable one.

I’d give it 5 stars but the demineralization filter doesn’t fit into the spot its supposed to, it won’t fully lock down into place and floats around when I use it. Anyone else have this problem?
1 reply from Dreo team - 10 days ago
Thank you for your feedback and for pointing out the issue with the demineralization filter. The filter should fit securely into its designated spot and not move around during use. Please double-check that you are aligning the filter with the correct slot as shown in the manual. If it still doesn’t fit properly, it may be a compatibility issue or a manufacturing defect. Please contact our support team using the email provided in your manual or by searching "DREO support" on Google. We’ll be happy to provide troubleshooting steps or supply a replacement filter if needed. Thank you for bringing this to our attention—we’re here to help!
