Notes: The table also shows the average airflow resistance and initial penetration measured for each model of PPE (n = 5). “N95” indicates that the PPE has been certified as an N95-class filtering facepiece respirator by NIOSH. “Surgical mask” indicates the PPE has been cleared for sale as a surgical mask by the FDA. Airflow resistance and penetration were measured using a standard filter tester as described in the Filter Penetration subsection of METHODS.
