There was over ninety% penetration for all cotton masks and handkerchiefs, and 50 to 60% penetration for surgical masks and nonwoven nonmedical masks.

It is also much harder to directly test masks efficacy for PPE using a human topic, so simulations have to be used as a substitute. Masks may be made of different supplies and designs which influence their filtering functionality. This subject has been subject to added confusion because of debates about whether these particles should be referred to as droplets or aerosols, with implications about their capability to stay suspended in air over time .
