And that's why I said it's not 100% full proof, doesn't mean that it can't reduce the rate of transmission. Masks largely decrease the spread of your own droplets/aerosols, they don't protect you much from aerosols of other ppl.

The virus also transfers through BOTH water droplets and aerosol.

There are 141 references listed in this review with multiple types of studies, including studies on the filtration rate of aerosol particles: https://www.pnas.org/doi/10.1073/pnas.2014564118

Here's another study, a mannequin simulation in a controlled environment using 3 types of masks: https://journals.asm.org/doi/10.1128/mSphere.00637-20

If you still think otherwise, do your own mannequin simulation and provide an unedited video of you working out your results. This study is easily repeatable.
