[This review was collected as part of a promotion.] I originally rated lower because the sensor didn't seem to work. I tried to get it to work and now it does. I really like it and it works well. Quiet and flows the whole living room and dining room. I think filters are expensive but most are expensive.

I like how quiet it is and the wifi mode. Not sure if the sensor works, I tried to trigger sensor but nothing happens.

I bought the purifier for the bedroom as my wife has allergies that can affect her sleep. The unit is very quiet and cleans the air effectively. The ability to schedule on/off times is great and we don't have to worry about having it on at the right times.
