CDC Recommendations, Contd... • Improve central air filtration: • Increase air filtration to as high as possible without significantly reducing design airflow. • Inspect filter housing and racks to ensure appropriate filter fit and check for ways to minimize filter bypass. • Check filters to ensure they are within their service life and appropriately installed. • Consider portable high -efficiency particulate air (HEPA) fan/filtration systems to help enhance air cleaning (especially in higher risk areas such as a nurse's office or areas frequently inhabited by persons with higher likelihood of COVID-19 and/or increased risk of getting COVI D-19). • Generate clean -to -less -clean air movement by re-evaluating the positioning of supply and exhaust air diffusers and/or dampers (especially in higher risk areas). • Consider using ultraviolet germicidal irradiation (UVGI) as a supplement to help inactivate SARS-CoV-21, especially if options for increasing room ventilation are limited. • In non-residential settings, consider running the HVAC system at maximum outside airflow for 2 hours before and after the building is occupied.
