Are you a doctor? Can you explain why a study about influenza would apply to SARS-CoV-2? Or is your doubt baseless speculation?

SARS-CoV-2 is a spheroid with a diameter of about 120 nm.

There's a lot of variation in influenza viruses, but most are spheroids or ellipsoids with a diameter from 80-120 mm.

For simple mechanical filtering, such as with a mask, they are going to behave pretty similar.
