By that measure masks do not work since N95 allows a certain level of particles to transit. Perfection is not necessary, only reducing the replication factor.
That's a stupid remark. N95 are used mainly to reduce the emission of our own droplets, not to eliminate it nor to make us invulnerable.
Still, the recommended approach is still to stay at home and avoid contact altogether. As it's obvious to anyone, no exposure is far better than some exposure.
