Cleaner air is nice.
Works well as described.  Helped noticeably reduce pet dander and other allergens in air. Filter is easily changed. Air quality sensor is on the front of the device whereas it pulls air from the sides so if pollutants are coming from beside or behind the device they may not be recognized by the air quality sensor but are still filtered. When the pollutants are coming from in front of the device it quickly recognizes them and alerts by changing colors and speed until the pollutant is gone.  Is very quiet in low setting and even on high the noise is more like a white noise in the background.  I have gotten used to it so I don't really notice it unless I am making a conscious effort to do so. The UVC light with the coverage area is what got me to purchase these after looking at more than I can remember.
