Masks vs filters for riders
A fitted N95 is the best mask for riding, but on real riders in Ho Chi Minh City traffic it stopped 60 to 80% of particles, not 95%. Surgical and cloth masks managed 25 to 60%.
The weak point is the seal, and a helmet breaks it. A closed visor or a buff does not seal either.
Filtered airflow takes the seal out of the equation: a fan pushes air through a HEPA filter and into the helmet, so the protection does not depend on how the mask sits on your face.
