BFE vs Breathability
Its important to understand that if there is high BFE then Breathability will be very low as low as 15. BFE is a test where Bacteria is forced through the layers of the mask which in general does not happen in Community usage. As a result the Breathability is a crucial factor as otherwise people remove the mask in every 10-15 minutes which is more detrimental.
Saffronele Masks we want good Breathability as our coatings will kill the virus while WR treatment will not lot any droplet stick to the surface.
