I have another air purifier from levoit that is not Wi-Fi capable. I did not think that it would be useful but I’m glad I got a chance to test this one out and learn how useful the Wi-Fi connectivity is! I keep this unit by my work desk and have it scheduled to turn on during the weekday during my work hours. I really like how I can control it with my phone or from the unit and the little nightlight is a nice touch. I don’t really care for it’s connection to Alexa but maybe I will find it useful some day. The unit is smaller so it would be perfect for small bedrooms or as a second in a larger space (which is how this one if being used and I can have it turned off when I don’t need it). I do wish that there was an auto setting that detects the air quality and adjusts the fan speed accordingly like my larger air purifier. But overall this is a great air purifier!
