La pandémie de COVID-19 a entraîné une forte demande de protection respiratoire, a provoqué une pénurie de respirateurs homologués et la production de protections respiratoires alternatives. Pour sensibiliser le public par le biais de la communauté scientifique, les masques et respirateurs les plus vendus dans le principal détaillant en ligne des États-Unis, Amazon.com, ont été évalués.
Background COVID-19 pandemic caused a high demand for respiratory protection, caused a scarcity of approved respirators and the production of alternative respiratory protection. To raise public awareness through the scientific community, bestselling respirators and masks in the United States leading online retailer, Amazon.com, were evaluated. Methods Ten respirators and masks, 5 Face Protective Equipment (FPE) and 5 Cloth Face Masks (CFMs), were evaluated compared to the N95 standard. Two groups were established with the intention of comparing all masks together. The fractional efficiency and pressure drop were measured and compared to the National Institute for Occupational Safety and Health (NIOSH) standards. In addition, grading factors for protection, comfort, and affordability were developed that can be used by the scientific community to readily disseminate to consumers for the selection of the appropriate respiratory protection. Results Two FPE provided acceptable efficiency (>95%) similar to the N95, while the remaining products were below or extremely below NIOSH standards. All products provided pressure drops within NIOSH standards (≤35 mmH20) ranging from 2.3-10.3 mmH20. The grading factors show that the CFMs have minimal protection, and the N95 has average comfort and affordability compared to all the products. Conclusion The N95 remains the best respiratory protection, and in the event of the next airborne pandemic, FPEs could serve as adequate alternative protection against the viral spread.
