This is the powerful fan that creates a refreshing breeze as it purifies air with germicidal UV light, an ionizer, and an electrostatic filter. As air is drawn through the fan, it passes over a UV-C light that scrambles the DNA of airborne viruses, mold spores, or bacteria, preventing them from replicating. In tests by an independent laboratory, the fan’s filtering system eliminated more than 98% of bacteria in an hour. The ionizer attracts larger dust particles and other impurities down to 0.3 microns so they can be captured by a washable electrostatic filter. The fan quietly moves a high volume of air for a CADR of 125 CFM thanks to an asymmetric, deep pitched fan blade and an aerodynamic front grid that boosts airspeed. Its head manually rotates 270º, allowing you to direct the airflow to every corner in a room. Adjusts easily to three heights (48", 33", 19") for use on a floor, tabletop, or nightstand. Recommended for 300' sq. rooms. Filter lasts up to three years. AC plug with 6' cord. White. 19"-48" H x 14 3/4" Diam. (28 lbs.)
