I put the PureZone in my home office and bedroom I can feel the difference in the air quality. I no longer am sneezing while I work, and my eyes feel so much better. It has made a significant difference. At night I place the PureZone on my bedside dresser and breathe clean air as I sleep. The PureZone looks beautiful with my home décor and it WORKS! I can’t say enough about this air purifier. Its a must for any home and room .
