I am OBSESSED with this air purifier. First, the display is easy to read, and color coded to match the air quality in the room. It makes it so clear to know whether air quality is suffering or not. It looks great in the room, taking up little space. It does not run when the air quality is good, saving energy. Plus, the filters don't need to be changed often which is hugely helpful! When it is running, it's super quiet.
