A field charger creates a series of electrically charged corona fields through which incoming air must pass. Since the air passes through many small electrical fields, rather than over a single charged metal wire or plate, more airborne contaminants are collected than in traditional electronic air cleaner systems. The difference between the CHG0064 and CHG0059 is likely just the size of the assembly. The CHG0064 is 25.8" x 20.3"
