I purchased this air purifier based on the good reviews and the great warranty that comes with it. I like the auto setting and ionization and the night light feature that dims it. It's nice looking in my living room and feel it's a well made product. The true hepa filter is another reason I purchased this. I could tell the difference in the air quality fairly soon
                    after I turned it on. It's very quiet on low speed which was a big factor for me to purchase this unit also. I appreciate the offer for a free replacement filter also. Thank you very much !!
