New preprint from J Lednicky & al: Isolation of SCV2 from air in a car driven by a COVID patient with mild illness. (Jan 15 2021).
While virus detected at all sizes, "Remarkably, viable virus was only detected in particles 0.25um to 0.5um)"

Automobiles are one of the worst places to be. Roll down windows, wear good, well-fitting masks, and especially use NO recirculation. https://twitter.com/patientsafe3/status/1349625479259586561?s=20
"The patient drove the car for 15 minutes w/windows closed and the A/C on, then parked it and exited, leaving the windows up and the air sampler running for an additional 120 minutes. Total collection time of 135 min to
sample 1.22 m3 of air within the vehicle"

Was "late model Honda Accord".
Unknown: Recirc setting? Fan speed setting? Actual model (so we can measure air flow), cabin air filter type? Even so, was only 15 minutes. However filters may have caught larger particles during the drive.
