Another strategy adopted by the CDC and health systems to protect healthcare providers caring for COVID-19 patients and patients under investigation in limited resource settings includes the use of elastomeric FFRs with reusable cartridges. Although elastomeric respirators have not been approved by the Food and Drug Administration for fluid resistance, they have been endorsed by the CDC as reasonable alternatives for N95 FFRs during the COVID-19 pandemic due to their filtration approval by the National Institutes for Occupational and Safety Health (NIOSH).2 Subsequently, elastomeric respirators have formed a major arm of the COVID-19 pandemic response strategy in many hospital systems...application/pdfenCreative Commons Attribution 4.0 InternationalArticlehttps://doi.org/10.1017/ice.2020.257
