Mask Filter Tests
All STYLESEAL filters are independently tested at Nelson Labs, USA and conforms to the ASTM F2100 standard at a particle size of 0.1 microns. You can read about our different filter types here.
The 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 these tests can be found below:
