Assessment of best-selling respirators and masks: Do we have acceptable respiratory protection for the next pandemic? - Published July 25, 2022
Highlights
• Respiratory protection alternatives were available during the COVID-19 pandemic.
• Ten bestselling alternatives from the online retailer Amazon.com were evaluated.
• Alternatives were Face Protective Equipment (FPE) and Cloth Face Masks (CFMs).
• Only two FPE out of 5 masks were comparable to the N95 in terms of protection.
• The remaining FPE and especially the CFMs were below adequate virus protection.

Abstract
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 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.
