"N95 Masks Proven Most Effective in Blocking COVID-19 Airborne Spread"
A University of Maryland study found that N95 respirators, particularly the "duckbill" type, are highly effective in preventing SARS-CoV-2 leakage into the air, blocking 98% of the virus. The research compared various face coverings and highlighted the superior performance of N95s over cloth, surgical masks, and KN95s, suggesting N95s should be the standard in healthcare settings during high transmission periods.
