f you're not familiar with how BWD works check this out: Putting the Tesla HEPA Filter and Bioweapon Defense Mode to the Test. Not familiar with the add your own HEPA install, but pretty sure there's no substitute for the BWD.
From what I've gathered through that thread and a few other places, I'm not sure that this is true. People are saying that the Bio-Weapon Defense Mode button is simply a shortcut that cranks up the fans in order to create a positive pressure to push contaminants out. One can set the fans manually, if this is really desired.
