4The Big Ass Fans Clean Air System Ion Generator kills >96% of bacteria and fungi on surfaces in 60 minutes. Bacteria testing includes Escherichia coli, Methicillin Resistant Staphylococcus aureus (MRSA) and Streptococcus equi and Fungi testing for Aspergillus niger. | All Ion and UV-C testing was completed in enclosed indoor spaces. In outdoor spaces overhead and directional fans can increase dilution airflow in occupied spaces. | Fan operating speed is proportional to the airflow delivered by the fan. Increased operating speed will increase the generation of ions for fans with ionization technologies. | Increased operating speed will increase the rate of room air mixing for fans with ionization or UVC technologies.
