Muy buena capacidad en litros, por lo que puede durar hasta varios días (en automático). La app para controlarlo desde el cel es LO MEJOR.

Overall Verdict / TL;DR: This is the best humidifier I've owned, hands down. The 6L tank is massive (it runs for days), and the "Top Fill" design is a game-changer for filling and cleaning. The "Auto Mode" is the best part; I just set my desired humidity in the app (e.g., 50%), and it manages itself. Full Review 1. Context (Why I Got This): The minute our furnace kicks on for the winter, the humidity in our large living room plummets. I'm talking static shocks every time I touch a doorknob, scratchy throats in the morning, and all my houseplants start to look sad and crispy. I was so sick of refilling our old, tiny 1L humidifier twice a day. I specifically wanted a large-capacity, smart model that I could integrate with Alexa and just have it work without me babysitting it. 2. First Impressions & Setup: My first thought unboxing this was about its size. The 6-litre tank is no joke, but the unit has a very sleek, modern design that blends in well. The absolute best feature is the Top-Fill Design. You just lift the main lid off, and the entire top is a giant, open bucket. I can fill it up right in place using a pitcher of water. My old humidifier involved hauling a leaky, gurgling tank to the bathtub and trying to fill it through a tiny hole—this is a massive upgrade. It also means cleaning it is a breeze; there are no weird, hidden crevices I can't reach. Connecting it to the VeSync app was simple (I already use the same app for a Levoit air purifier). The app found the humidifier instantly, I connected it to my WiFi, and then linked it to my Alexa account. The entire process from unboxing to "Alexa, turn on the humidifier" was under 10 minutes. 3. Performance & Daily Use: This humidifier has been running for a week, and it's perfect. • Auto Mode: This is the #1 feature. In the app, I set my desired humidity level to 50%. The humidifier has a built-in sensor (a "humidistat") that reads the room's current humidity. It automatically turns on when the humidity drops below my target and, more importantly, turns itself off once it hits the target. I never have to touch it. No more worrying about over-saturating the room or waking up to damp walls. • Massive 6L Tank: This is the #2 feature. Because it runs on Auto Mode instead of blasting on high 24/7, a single, full tank lasts me almost three full days before I get a notification on my phone that it's time to refill. It's incredible. • Smart Controls: The VeSync app and Alexa integration work flawlessly. I can check the room's humidity from my phone, set schedules, or just say, "Alexa, set the humidifier to 45%." • Quiet & Night Light: It's an ultrasonic humidifier, so it's extremely quiet. On the low or medium setting, it's just a faint, pleasant hum and gurgle. It has a built-in night light, which you can set to dim, bright, or (thankfully) COMPLETELY OFF. • Essential Oil Tray: This is a nice bonus. It has a small, separate tray (you add oil to a pad, not directly into the water tank). It gives off a very subtle, pleasant scent in the room. 4. Key Pros & Cons: Pros: • True "Auto Mode" with a built-in humidistat. • HUGE 6L tank means you refill it every few days, not every few hours. • Top-Fill design is incredibly easy to fill and, most importantly, to clean. • Smart App & Alexa controls are reliable and genuinely useful. • Whisper-quiet ultrasonic operation. • You can turn all the displays and night lights completely off. Cons: • It's a cool mist humidifier. This is standard for ultrasonic models, but if you're looking for a "warm mist" unit to heat the air, this isn't it. • The unit is fairly large, so you need to make sure you have the floor or table space for it. 5. Value & Final Recommendation: For a smart humidifier with this large of a capacity, this is in a very competitive price category. The features that save you time (the giant tank, the top-fill cleaning, and the set-it-and-forget-it Auto Mode) make it an amazing value. You're not just paying for a humidifier; you're paying to not have to think about humidity all winter. Final Verdict: This is a 10/10. It’s a powerful, convenient, and well-designed appliance that fixed our dry winter air problem in a single day. If you hate refilling humidifiers and love smart home tech, this is the one to get.

great humidifier. Holds adequate water for hours, multiple settings, night light and is quiet. I do not need all the bells and whistles of apps or remote control but that is also provided. I have two and both have been working continuously since the arrived. No issues so far. Can recommend.
