Review: 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.
Review: 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
*by D***D on January 21, 2026*

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.
