Impact of microwave and heat decontamination interventions on aerosol penetration through N95 filtering facepiece respirators. Treatment replicates are denoted by n. Horizontal axis and effect sizes represent the differences in percentage aerosol penetration between untreated and treated masks. Within-study data for different masks and treatment parameters are averaged to yield a single effect size. Results are only depicted for studies that used National Institute for Occupational Safety and Health certification testing procedures. RE, random effects.
