We got this air purifier and we really like it. First off it was pretty easy to set up and connect to my phone. It's connected to an app on my phone and I'm able to have it turn on automatically every day at a certain time and turn off. It's pretty quiet, also it let's you know the air quality in the room. You don't have to use app to make it work, it has the normal buttons to turn on off high and low.
