Let's talk air flow in BART cars:
BART cars filter & replace inside air about every 70 seconds. This was the case before COVID-19 and is still now. Air is filtered more effectively than in an office or grocery store.
We've also begun new pilot tests for better filtration. pic.twitter.com/Wpw87HC49m
