A comparison and review of a Smartmi (Xiaomi) Evaporative Humidifier 2 and a generic Ultra Sound Humidifier. One make a mist and one not. One is silent and one not. One is hard to clean and fill up, and one not. One has smart features and one not. I prefer a mist-free and silent humidifier with art features that is easy to clean and fill up. Don’t you?
