N95 masks use a special fiber mesh made from "melt down" material to obstruct the passage of viral particles. Surgical masks are for droplet protection only. It is disingenuous in the extreme to make claims that a surgical mask can be "upgraded" to an N95. You can improve the airflow yes, but you should make the claim that it might be better than a standard surgical mask, not anything like an N95.
