We encourage our customers to do their own due diligence. We have cited two articles below while making no claims of effectiveness.

"Polypropylene is a commonly used material for N95 masks. To get through a filter made out of interlaced layers of polypropylene fibers, small particles have to wind through a rather tortuous path and as a result tend to get stuck, as described by a National Academies of Science, Engineering, and Medicine (NASEM) report that Jayaraman helped author. Think about getting through the filter material as getting through the entire crowd at a BTS concert."
