I can't live without having a humidifier at nights, it doesn't matter the season, my throat gets as dry as sand so I am always looking for the best humidifier in the market and oh boy, did I find my new favorite! The features on this unit are simply superb but you can read the box to know them so I'll just tell you my favorite ones: 1st of all, I refill water from the top!! Forget the annoying tank removal and dripping water all over the place. 2nd, the voice command!! Through my Alexa, I can turn it on with just my voice. I just love intelligent devices! This unit is quiet and enough for a big room. Did I mention the app where you can check humidity levels of the room?! I mean, what else do you need? Just run and get one, you won't regret it.
