Very quiet with great mist!! App + Alexa
I totally love this humidifier. It shoots a fine mist out, which is nice in a room with ceiling fans. I suffer from COPD and if I do not have humidity level set consistently between 40 and 50%, I start to have bad breathing problems. Pros: can connect to Alexa. I’m also able to control it through the app through Wi-Fi. The app has never failed me and it has worked perfectly when I need it to, every day. The filters that are sold separately I highly recommend and I really like using them because prior to purchasing them I was cleaning my machine every week. Cons: because it’s so small you have to fill it frequently. I have to clean it every week to prevent hard scale buildup as I am unable to purchase distilled water every day. (full disclosure when I use the filters that are sold separately I have to clean it out maybe once every five or six weeks. For the price, I highly recommend this product. I do not believe you will doubt your purchase when you use it for the price and the availability to use AI and the app you can pretty much control it anywhere. You will not find another humidifier within that price that has those same features with an app that actually works.

works so well i bought a second
works so well i bought a another for use in our daughter’s college apartment. it made a huge difference for me during the winter months and allergy season. they hold a gallon of distilled water, it’s easy to clean and refill. it’s very quiet. the light can turn off. the app is easy to use. the cleaning reminder is helpful. the schedule feature is great. the humidity range is fantastic. i love knowing that even if it’s scheduled it won’t run if your home’s humidity is higher than the setting.

My New Favorite
I use this humidifier every night on my nightstand. My favorite feature is the fact that once it runs out of water you can simply open the lid and pour water into the reservoir then it will start back up immediately! No more running back and forth from my kitchen with a big heavy water reservoir when I can just make a few trips easily filling this. The humidity levels are perfect for your basic needs, the winter is horrible for me so having this 24/7 is making the static and dryness a little easier to handle, not to mention the help it provides when recovering from winter colds. The weight is very light and I think the overall design makes it easy to move when needed. I cant speak much to durability but my cat hasnt been able to break it so I think it has passed my test. The light settings are also very nice and pretty. The ability to shut off all lights on the unit at night and the complete lack of noise it has makes it very easy to sleep next to as well. Overall this one is much better than my previous old humidifier.

Reliable Humidifier for Daily Use
We use this humidifier every day, and it works consistently well. It feels well made, has been reliable, and offers excellent value. Program to be on overnight. Low noise. Nice collor. Nice size. Have to fill every three days.

Works great overall, small quirk when it runs dry
I’ve been using this for a couple weeks now in our bedroom and overall it’s been great. The Alexa setup was easy and it integrates well with the rest of my home automation. I’ve got it set at about 50%, and it’ll run for roughly two nights before needing a refill, which is pretty reasonable. The only issue I’ve run into is when it runs out of water in the middle of the night. When that happens, it won’t respond to the scheduled shut-off command from Alexa. Not a huge deal since I have it set to turn off at sunrise anyway—I just hit the power button after refilling. Minor inconvenience, but overall it works really well and does what it’s supposed to.

Great humidifier
I bought these to use for my house plants. I love that I can set a humidity percentage through the app and the humidifier will maintain that humidity level. If the humidifier runs out of water it automatically shuts off and sends you a notification through the app. This unit is silent as far as I am concerned, the mist is very fine and is working well for my plants. I like that the unobtrusive lights in it (which can be turned off) let's me know if my current humidity near the humidifier is in its target range (green) or if it's dry (below target humidity, yellow/orange) or wet (above target humidity, blue). You can use the app to turn the device on/off and to adjust the humidity, this is also where you control whether the humidity indicator light is on or off. I recommend it highly, I am considering getting the size up to be able to cover more of my room space. This unit holds a full gallon of distilled water when filled from totally empty, if filling from auto-shutoff it will take slightly less than a gallon. They manufacturer recommends using distilled water to avoid lime scale as do I. We have very hard well water and uso g distilled has saved us from having to descale.

DON’T HESITATE, PURCHASE IT AND YOU WON’T REGRET IT!!!
I’m one of those people who purchase items at Amazon and only realize later I have to make another trip to the UPS Store. FINALLY a GREAT product that will not be going to the return bin. The humidifier is beautifully designed. What? A plain old humidifier beautifully designed? Yes! There is the base, the tank and a cover. However, the large center column that pushes out the water is backlit and changes colors depending on amount of humidity in the room. Three different colors show dry, comfortable and wet. I’m sitting in the bedroom looking at this unit and I find sometimes I just stare at it. The water shoots up the column out the top but since it’s backlit you see bubbles in the water and with the light it’s sort of looking at the bubbles in a fish tank. Am I weird that I find the reverse waterfall captivating? I guess I am because just looking at the tank is very relaxing,(yes really!) There are so many things I like about this unit that to list them all now would take three pages. As far as controlling the unit, DREO has its own app that you use to totally control the humidifier: level of humidity, beep sound on/off, turn front LED display on/off, auto/manual and level of mist entering a room. The app does pretty much everything you want to activate all the controls. If you are sensitive about noise in a bedroom when you are trying to sleep, I can honestly say that the unit is extremely quiet. As I stated, if lights or noise disturb you at night, you are able to turn off front display, light in center console and switch it to totally auto control without having to worry about adjusting air flow or amount of humidity. All you have to do is press sleep mode on the app itself. On top of all this you’re able to control the humidity with Alexa so you don’t even have to get out of bed. It’s not very often that I rave about a product for sale on Amazon, however this appears to be an almost perfect appliance with a great app. Oh yes, app was very easy to set up and guides you through every step including linking it with Alexa. Is this a perfect find? Could be however I’ll update this review after I’ve used it for a while but as of now I don’t foresee any problems! UPDATE: 3/2/2025 As a former engineer I am very selective about the products I purchase, and now sure enough I have a gripe! I’ve found that while utilizing Alexa you are unable to ask to change humidity level. I said “Alexa increase humidity level” but it did not respond. Sort of like a lot of guys talking to their wives! I’ve also discovered that in auto mode it defaults to a very low output which was not effective to increase the humidity in my master bedroom. Funny that it’s called a MASTER bedroom because the dog runs the house and not me!!

Dreo smart humidifier
The scent tray was disappointing when it stopped working after a couple of months, but you clearly enjoy the app controls, Alexa integration, cleaning reminders, and those status lights. Even if you're unsure about the actual humidifying effect, you're still it's still a positive experience overall. Here's a cleaned up version in your voice. I've been using this humidifier for a while now, and overall I've had a pretty good experience. I'd give it four out of five stars. The biggest reason it's not five stars is the scent feature. When I first got it, I really liked being able to add fragrance to the scent tray. It made my room smell really nice and was one of my favorite features. Unfortunately, after about two months, the scent tray just stopped working. I tried cleaning and troubleshooting it, but couldn't get it going again. That was disappointing. Aside from that, I think it's a really nice humidifier. I love that it connects to an app on my phone, so I can control it without getting out of bed. It also sends reminders when it's time to clean it, and lets me know when it's running low on water, which is really convenient. Another feature I enjoy is the colored lights that change to show the status. It works with Alexa too, so I can turn it on or off with voice commands, which is another feature I use regularly. I can't say for sure if it helps with congestion, but I haven't noticed a big difference, though it might be hard to notice day to day. For 49.99, it's a little pricey, especially since the scent feature stopped working. But I still like using it. So, overall, with all the smart features, it feels like a solid purchase. If the scent tray had kept working, it would have been five stars for me.

**Dreo Smart Humidifier for Bedroom - Product Review**
I recently purchased the Dreo Smart Humidifier, and I'm quite pleased with its performance. Here are my key takeaways: 1. **Easy Setup**: The humidifier was straightforward to set up right out of the box. The process took only a few minutes, making it user-friendly for anyone. 2. **Water Requirements**: It's important to note that the Dreo humidifier operates best with distilled water. I've been using Winstons ARION Distilled Water (100% Pure Steam Distilled Water, 5 Litres by UINCLU), which has proven effective in maintaining optimal performance. 3. **Cleaning and Maintenance**: For continued efficiency and quality, it’s essential to clean the unit and change the water every 100 hours. This routine maintenance ensures the humidifier functions properly and delivers the best results. 4. **Improved Air Quality**: The humidifier has significantly improved the air quality in our bedroom. Our room's humidity level was around 32%, which is quite dry. With the Dreo humidifier, we’ve been able to increase it to the recommended 45%-50%. 5. **Relief for My Son**: Most importantly, the humidifier has benefited my 4-month-old son, who previously struggled to breathe comfortably at night. The increase in humidity has alleviated his nighttime breathing issues, making for more peaceful sleep. 6. **Design and Features**: The humidifier has a modern design and is relatively quiet, which is crucial for use during the night. The additional smart features, like scheduling and adjustable mist levels, add to its convenience. In conclusion, the Dreo Smart Humidifier is a reliable solution for improving bedroom humidity. With proper maintenance and the right water, it has proven invaluable for our family, especially for my young son. I highly recommend it for anyone dealing with dry air issues.

Een echte aanrader!
Prima luchtbevochtiger. Instellen van de app was vlot te doen. Zelfs het instellen van een mede gebruiker was geen probleem. Nog maar enkele weken kunnen gebruiken maar voldoet voor ons uitsteken. Is echt een aanrader.

Absolument parfait.
C'est le quatrième humidificateur d'air que j'essaie, et c'est de loin le mieux fini, le plus élégant, mais aussi le plus complet et agréable d'utilisation que j'aie eu. Clairement haut de gamme, il est déjà livré dans un carton bien pensé avec des notices claires. L'appareil est beau et robuste, compact, le bac d'eau est amovible pour le remplir sans avoir à le débrancher. Il est silencieux et réellement efficace, produisant une vapeur dense, rapide et orientable dans trois positions (derrière, verticalement, devant), et ceci peu importe le niveau de brume choisi (3,3-,2,2-,1,1-), ou alors en mode automatique pour atteindre l'humidité demandée. La fonction huiles essentielles marche remarquablement bien et ne consiste pas simplement à en verser dans l'eau, ce qui fait des gouttes isolées, mais à imbiber un coton qui s'insère ensuite dans un tiroir, même pendant le fonctionnement. Les 4L sont parfaits pour tout type de pièce et tiennent plusieurs jours. L'application est juste parfaite, point le plus étonnant, aucune pub ou achat intégré, fluide même sur des vieux téléphones, l'appairage est instantané et toutes les options auxquelles vous pouvez penser y sont : programmer des actions en fonction de l'heure et du jour, ponctuellement ou non, ajouter un timer, éteindre/allumer l'affichage ou la led, personnaliser les plages d'humidité... et inclue des rappels de nettoyage et des conseils de maintenance natifs, qui ne sont pas des liens internet, le tout compatible avec Alexa ou l'assistant Google. L'appareil enregistre les instructions, ce qui fait que la programmation persiste même si vous n'êtes pas chez vous, si votre téléphone est éteint, que vous désinstalliez l'application ou autre, et est pilotable depuis l'extérieur, que vous soyez en 4G, dans un autre pays... C'est un vrai écosystème domotique compatible avec tous les appareils de la marque, mais qui peut très bien être utilisé uniquement avec l'humidificateur. Je suis tellement élogieux qu'on pourrait croire que je suis payé ou que je l'ai reçu gratuitement, mais il s'agit d'une évaluation spontanée, étant ravi par mon utilisation depuis 4 jours maintenant. Aucun doute que ce sera le dernier humidificateur que j'achèterai. En définitive, la différence de prix avec les autres modèles sur Amazon est largement justifiée. A vous de savoir si vous avez assez à mettre dans un humidificateur/diffuseur d'huiles essentielles.

Stupendo, economico e funzionale.
Bellissimo e ottimo umidificatore smart wifi con gestione da app dedicata DREO, 3 livelli di potenza diversi con spinta del vapore nebulizzato con una ventola... Gestione della percentuale di umidità automatica, possibilità di regolare accensione e spegnimento ad orario oppure continuo con stop al raggiungimento della percentuale scelta. Led interno che oltre ad illuminare indica il range di umidita ideale, sotto la soglia di umidità è giallo, nel range è verde e sopra è blù, come nelle foto. Il range è regolabile in base alle esigenze, di default è tra 30 e 60% ma secondo me 30 è basso e l'ho regolato tra 40 e 60%. Sportellino con spugnetta assorbente dedicata per oli essenziali (a differenza di tanti che dicono che non è presente, o son ciechi o meglio che nn mi esprimo come vorrei), molto comodo e funzionale... Gestibile anche da assistente vocale (alexa e google home) che funziona perfettamente.. io personalmente uso soprattutto Alexa e riesco a comandare accensione, spegnimento, accensione e spegnimento del led interno, livello di potenza, percentuale di umidità, ritardo di accensione e spegnimento... Praticamente tutto.... Soddisfatissimo... Acquisto consigliato...
