this is a weird question during COVID but does anyone know **particulate** filtering masks that have enough airflow for high effort on a bike?

it doesn't need to be covid-levels of filtration, I just want to be breathing less exhaust from every car running rich or diesel truck.

right now I just hold my breath at intersections, which isn't really all that safe or tenable.
