*For BFE, it is important to note that the size of the particles used, as use of larger particle size will produce a misleading PFE rating.As for ASTM F2100-07, Standard Specification for Performance of Materials Used in medical Face Masks, it specifies that a particle size of 0.1 microns to be used with the PFE Surgical Masks microdia healthcareFDA/CE approved N95 - 5-layered design . BUY WITH CONFIDENCE - This mask is officially certified by FDA and CE with N95 standard, which ensures filtration efficiency of at least 99% (BFE/PFE/VFE) and 95% for particles as small as 0.3 microns.The most imporant barrier DentistryIQBoth the BFE and the PFE of a mask is important. For example, a mask with a BFE rating of 99 percent at 3.0 microns provides less protection than a mask with a PFE of 98 percent at 1.0 micron. Do not be misled by a high BFE/PFE rating without knowing the particle size upon which it is based.
