@gardengirl778 @RonRRossi @j_g_allen @olgakhazan Aura has a fit test pass rate in untrained individuals of about 85% (was authorized by FDA in 2008 for public use), and other N95s are usually in the 60-70% range. If you subjectively have a "reasonably good" fit, you're well protected, certainly much better than without.
@gardengirl778@RonRRossi@j_g_allen@olgakhazan Aura在未经培训的个体中的适合测试通过率约为85%（2008年经FDA批准用于公共用途），其他N95通常在60-70%范围内。如果你主观上有一个“相当好”的身材，你会得到很好的保护，当然比没有保护要好得多。
