I bought 2 of these 45i, and I can say that I was confidently satisfied with its performance in purifying the air I breath each day and night. I currently set in auto mode, and I can honestly say that I can really feel that the air I breath is clean and pure.
I researched many air purifiers and I am so happy that I chose this product for me and my family...so quite and blends very well with the surrounding my rooms.
Great product!!
