Assessment of best-selling respirators and masks: Do we have acceptable respiratory protection for the next pandemic?

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 dissemi-nate 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 stand-ards (<= 35 mmH2O) ranging from 2.3-10.3 mmH2O. 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.(c) 2022 Association for Professionals in Infection Control and Epidemiology, Inc.

Automated summary

COVID-19 pandemic led to high demand for respiratory protection, causing a shortage of approved respirators and the emergence of alternative options. In this study, popular respirators and masks available on Amazon.com were evaluated. Only two face protective equipment (FPE) met the N95 standard, while the rest fell below or significantly below NIOSH standards. Despite this, all products had pressure drops within NIOSH standards. Cloth face masks (CFMs) offered minimal protection, while the N95 had average comfort and affordability compared to other products. The study concludes that the N95 remains the best respiratory protection, with FPEs serving as adequate alternatives against future airborne pandemics.
