We love this PureZone air purifier! I own a dental practice and did a lot of research to find a good quality air purifier that suited the needs of my practice. This product has great HEPA filtration, optional ionization, a UV bulb and robust air flow turnover to ensure the aerosols produced during our procedures are filtered well, and filtered fast, resulting clean air. I bought 2 in June and loved them so much I purchased more. Along with fantastic specifications, this air purifier also looks great! I'd highly recommend it to anyone looking for a good quality, well priced and nice looking air purifier!
