I live in the desert and air quality is not great. So I needed to do something to male sure that at least at the house we are breathing some good quality air. After an extensive research I got to this air purifier. I'm so glad I chose it, it's been doinv a great job! I'm plannin on buying one more, as one can't keep up with the whole house. It was really easy setting it up and it is pretty quiet,  which is really important.  Great quality!
