what is your conclusion? Are you wearing a better mask?

Virus does not travel by itself, it attaches to small particles. Masks have not only mechanical filters, but also electrostatic that attracts those particles. A bigger problem is gaps even with proper masking, kal vhomer with half-worn.
But behavior and environment are probably more important. If you don’t stay long in poorly ventilated rooms with other people, you’ll reduce your risk and probably severity in case of getting it. If you lock yourself in a closed room and windows with a large group singing nigunim, N95 might not help.
