Very Good Humidifier, So Far
Perfect for a decent size area of the home. Super quiet. Barely hear this humidifier running, even at full speed. It's easy to fill when needed. All functions work and I love the mist as it comes out from the top. Love that the mist can be directed if needed. Lighting is nice and soft, too. Easy to put together and relatively easy to clean. I like that it will shut off once the tank is empty. The slot for fragrant oil is nice... just do NOT put anything but water in the tank. As for the app that can be used to control this humidifier, I prefer not to use it, but it works fine. There are some concerns as to the white dust that can accumulate on the unit itself and the surrounding area. If you don't like dust, then this may NOT be the machine for you. No issue for me, but I know others don't like the fine particles of the evaporated water left on all surfaces after a week of running this humidifier. Best to use distilled water if you don't want as much dust. Cleaning will take some time. The water will get "icky" in base after 3 days. While it's easy to take apart, each and every piece needs a wipe down that has any contact with the tank and base water. After a week or so, it's best to use vinegar to remove the hard, mineral deposits and possible bacteria that can build up. It definitely needs clean-up care. All and all, I love my Dreo humidifier as do all my plants that surround it. This is my 3rd Dreo humidifier and I can't imagine not having on during the cold season.

A Game-Changer for Air Quality, Sleep, and Plant Health
I’ve been using the Dreo Smart Humidifier (6L, Black) for a few weeks now, and it’s honestly one of the best purchases I’ve made for my bedroom and plants. It perfectly balances functionality, design, and convenience. ⸻ 🌬️ Performance & Mist Output This humidifier is powerful yet whisper-quiet. Even on the highest mist level, it barely makes a sound—perfect for sleeping or studying. The 6-liter tank easily runs for two to three days straight without refilling, which is amazing compared to smaller models that need daily attention. My peace lily and other indoor plants have perked up noticeably since I started using it. ⸻ 🧠 Smart Features The Dreo app integration is super convenient. I can control mist level, timer, and humidity targets directly from my phone or even with voice assistants like Alexa or Google Home. It also auto-adjusts mist output based on the room’s humidity, which helps maintain a steady, healthy environment without over-humidifying. ⸻ 💧 Ease of Use & Maintenance The top-fill design makes refilling so simple—no need to detach and carry a heavy tank to the sink. Cleaning is easy too, with wide openings and detachable parts that don’t trap mold or residue. Plus, the built-in water level sensor prevents it from running dry and damaging the unit. ⸻ 🌙 Night Mode & Design The night light feature gives off a soft, calming glow that’s great for bedrooms or nurseries. You can adjust the brightness or turn it off completely. The modern black design looks sleek and fits in perfectly with almost any décor—minimalist, cozy, or modern. ⸻ 🌿 Perfect for… • Bedrooms and medium-to-large rooms • Houseplant owners who need consistent humidity • Babies or people with allergies/dry skin • Those who want a low-maintenance, smart-controlled humidifier ⸻ ⚙️ Minor Notes The only small drawback is that the app setup takes a few minutes the first time. But once connected, it’s smooth sailing. ⸻ ✅ Final Verdict The Dreo Smart Humidifier 6L is quiet, powerful, easy to maintain, and beautifully designed. Whether you’re trying to improve air quality, sleep better, or keep your plants healthy, this humidifier delivers exactly what it promises—and more. Highly recommended.

top filling feature is a godsend for us seniors
I recently bought this smart humidifier to replace one that my wife accidently broke trying to fill it and return the water tank to its base. "Why can't they sell a humidifier I can fill from the top?" Well this one fit that bill nicely. no more walking the tank to the tub to fill and then flipping it over to nest back into the base. This one has a large lid that you can easily lift off and use a pitcher to pour the water into the tank. A much neater and easier process! This one has bells and whistles that are just an added bonus for us as seniors. You can run the humidifier remotely using their app, that allows you to set the humidity level you want to acheive, but also you can schedule the days and times you want it running or turned off. It also sends a note to your phone when the tank is empty and needs refilling. You can also buy separately demineralizing filters that will draw away some of the minerals dissolved in your tap water, reducing the white dust that ends up everywhere on other mist humidifiers as well as prolongs the life of this machine. While it is still new for us, I am very happy with how it has worked for us so far.

Great Performance and Design, but Built-In Hygrometer Is Inaccurate
The Dreo HM524S works very well as a humidifier. It looks good, runs quietly, and the black color option fits nicely into a living room without looking like a cheap appliance. Output is strong, the tank is easy to fill, and there are no filters or wicks to replace. Wi-Fi setup was quick, and the app works reliably for basic control and scheduling. Where this unit falls short is the built-in hygrometer. As shown in the photo, the HM524S reports 48% humidity while multiple external hygrometers in the same room read around 24%. In my testing, the internal reading is consistently off by roughly 20–25%. Because of this, the auto mode can throttle output too early unless you manually compensate by setting a much higher target humidity. The humidifier itself performs well and does raise room humidity effectively, but the internal humidity reading should not be trusted as an accurate measurement of actual room conditions. If you already use a reliable external hygrometer, this is manageable. If you’re expecting precise “set it and forget it” humidity control based on the built-in sensor, this will be frustrating. Bottom line: Quiet, attractive, effective humidifier with a solid app experience — but the inaccurate built-in hygrometer is a real drawback and should be noted before buying.

It stopped working after just one month of use, despite my careful adherence to the cleaning and maintenance instructions.
