I think we should wait for Corsi and Rosenthal lab work on this topic

  a difference is that those masks were designed and certified at that level, which aides adoption

    labs don't certify that mask is more effective per dollar compared to usual air filters. hence extra research by Corsi and Rosenthal is needed. After they will do the measurements they can be declared as inventors of p100 masks, that will be known as Rosenthal-Corsi masks

      The p100 masks are already certified so you can shop based on cost. Filters + fans are not certified so you have to know something more to understand what you are getting
