Super easy setup and connected seamlessly to Alexa. I have tried this in each room of our house and now I feel like I need multiple for a variety of rooms. We all have very bad allergies and asthma so it was put in my son's bedroom since he has the most issues and it has definitely made a difference in his room.  I love that I can see the air quality and change settings from the app on my phone and also that it has a lock on the buttons that can be set in case my toddler does happen to get in the room and try to mess with it ( she's not allowed in but she does manage to sneak in sometimes). It's pretty quiet and does have a sleep mode to reduce noise further during bed time.  It is also lightweight and easily portable.  My son named it since it is in his room, but you can pick any name and picture for it you want.
