Wow. Good find.

However, N95 was found to be most effective in limiting the spread of cough droplets. Leung et al.91 performed experimental studies to investigate the efficacy of surgical facemasks to prevent respiratory virus shedding. The surgical facemasks’ efficiency was measured against the coronavirus, influenza virus, and rhinovirus of two broad particle sizes, respiratory droplets (≥5 μm) and aerosols (droplet nuclei with aerodynamic diameter ≤5 μm). The results indicated that surgical facemasks could efficaciously prevent the transmission of human coronaviruses and influenza viruses into the environment in respiratory droplets, but no significant reduction in aerosols.

I bolded the parts that I've been saying for months.
