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.

Excellent. Buy this.
I have a Dreo wall hanging heater that I love so I thought I’d try this. It uses the same app and is easy to set up. I am ecstatic with this product. Extremely quiet and pumps out water vapor. Having the humidity level setting on a product at this price point is amazing. The ambient lighting feature doesn’t provide any value to me and seems to be a silly feature. Definitely the right size for a traditional bedroom for non McMansion houses. A little undersized for a normal living/family room. I have soft water so do not get calcium build up. There are no complicated filters although you can buy a filter to add on from Dreo. Cleaning is simple. I love that there aren’t consumables that cost money constantly. Extremely satisfied with this product.

Good unit, good company
This is a cool machine. The app works well and is easy to use. It is a quiet unit and will kick out the moisture if you set it on high. We have set the unit on high humidity and had the entire house look smokey. We bought a second unit because we liked the first so well. It’s light to refill and last a few days depending on the moisture output.On a separate note. I can speak on the DREO brand and people that work there as well. We had a slight problem with one unit and they replaced the unit with very little difficulty. If you want a quality humidifier, here it is. I’m not a paid actor just a user with a humidity controlled house.

Smart Humidifier
I have used this product for several months. I like the streamlined shape and compact size that make it easy to have on my bedside table. I like the versatility of adjusting the mist flow. The readout for humidity level is very helpful as I live in a typically dry climate. It is very quiet compared to other humidifiers that I have used in the past. The app works great to let me know when the humidifier needs assistance or water refill. It shuts off automatically when it no longer has water in it. The tank is easy to remove and refill. The filters are very easy to replace and easy to order replacement parts

AMAZING – ish!
I know I shouldn’t get this excited over a humidifier, but this thing is amazing!! It’s so easy to set up and sync with my phone and Alexa. The top fill option is great and for something that looks so compact it holds a lot more water than you’d think. And the best part for me is the way you can set it to EXACTLY the level of humidity you want in your room/home and walk away. It tracks the humidity in your air and shuts itself off when it reaches the level you want, so a single fill can last for days. Then starts back up again when it drops below optimal. And of course it shuts off and notifies you when it has run dry. It even tells you when it’s time to switch out the filter. You can control of this from anywhere with your phone or by voice using Alexa. I will recommend this to everyone. **UPDATE** Still love the functionality of this humidifier, but the filter that is supposed to eliminate the white dust is a bit of a disappointment. After several days of use EVERYTHING is covered with a layer of super fine dust. Plan to dust often.

Best humidifier with lots of adjustments
After using inexpensive humidifiers, I am very impressed with the Dreo. The mist is fine and steady and doesn’t create puddles from too large droplets. It is very quiet which is very important. It sits right beside the bed where my husband sleeps and keeps his breathing easy. There is no moisture on the bedding and he no longer coughs from dry air. He was coughing 4-5 hours a night. I like the ability to adjust the amount of mist and strength. The light is a nice feature when convinced family to buy this brand. My hope is that it is sturdy as we use it every night.changing settings in the night. I have

Beautiful Design, Works Exactly as Intended
I originally bought this humidifier as an addition for another room to help my plants, not to replace my main one—but I ended up loving it. The water feature is almost like a rain system, with water gently trickling up the center, which is a really nice touch. The ambient lighting adds to the overall aesthetic, and it humidifies very well. The app is functional and easy to use, and scheduling on/off times works exactly as intended. Overall, it’s both effective and visually appealing.

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.

Quick delivery and nicely packed. It works great. Very good for standard rooms size. Not for massive or very big rooms. It detects humidity ratio in the room and App works fairly well. Good product. I hope it will last, so let’s see its performance after a few months of use. For the moment I consider it to be a great choice.

Très bon produit, efficace et silencieux, vraiment !Efficace : j’ai un hygromètre précis qui me donnait une valeur plus basse que celle indiquée par l’appareil et j’ai d’abord pensé que celui de l’appareil indiquait un peu ce qu’il voulait… Mais en fait, c’est normal, il faut attendre que l’appareil ait rempli la pièce d’humidité et au bout de quelques dizaines de minutes les deux donnent bien la même valeur.Silencieux (ou presque) : j’ai l’oreille très sensible et le moindre bruit me réveille. Je craignais d’être obligé de l’éteindre la nuit pour pouvoir dormir, mais à ma grande surprise, il ne m’a pas dérangé en étant posé sur une table à 2 mètres de ma tête, en mode nuit bien sûr !Je ne l’ai que depuis 2 semaines, mais la construction à l’air de bonne qualité et je pense qu’il va durer dans le temps.En plus, il n’est pas moche, discret et à une bonne contenance qui permet de ne pas avoir à le remplir pendant plusieurs jours. Mais ceci dépend beaucoup de votre environnement, chez nous, le chauffage n’étant pas encore allumé, le besoin d’apport en humidité n’est pas encore très important, donc à voir…Passé ces considérations, pour le moment, je recommande chaudement !

After a disastrous experience with a GoveeLife model that leaked and ruined my furniture, the Dreo has been a breath of fresh air. It’s quiet, efficient, and most importantly, the build quality feels secure and well-engineered.Smart Features: The built-in hygrometer is very accurate, which saved me from buying a separate sensor. The app integration is excellent; I love getting “low water” alerts on my phone and being able to set schedules for the dry Toronto winters. It has significantly improved the air quality in my bedroom.Pros:Very quiet operation (perfect for sleeping).Smart app control and accurate humidity sensor.Top-fill design makes it very easy to clean and refill.Cons:The 4L tank lasts about 12-15 hours on high; you’ll need to refill daily during peak winter.The mist output is powerful, so don’t place it too close to electronics.
