The range doesn't tell the true story. In Figure 5, the majority of models are worse than surgical masks, above 20%, vs "Particle penetration through the surgical mask ranged from 2% to 17%". Only 3/13 performed better, and 1% is just the lower quantile for a single one of them.
- maxerickson 6y agoRight, and the ones that perform the best? Presumably if the goal was to standardize on good valve performance, the performance would align with the best models rather than the majority.
- incrudible 6y agoYou are still conflating the mask cloth with the cloth mask. It is not plausible that a loosely worn cloth mask performs nearly as well as the cloth itself.
