ASTM F2100 PFE / BFE / VFE Mask Filter Tests

Below you will find all STYLESEAL mask filter test reports. Our filters are independently tested at Nelson Labs, USA and conform to the ASTM F2100 standard at a particle size of 0.1 microns. You can read about our different filter types on the filter technology page.

The mask filters go through a variety of tests including:

  • Particle Filtration Efficiency (PFE)
  • Bacterial Filtration Efficiency (BFE)
  • Viral Filtration Efficiency (VFE)

This is your guarantee that STYLESEAL Air Masks provide you the protection you need. All results of the mask filter tests can be found below:
