BACTERIAL FILTRATION EFFICIENCY (BFE)
BFE is an independent test conducted by approved Independent testing facilities that measure the effectiveness of face mask materials to filter out bacteria.
PARTICULATE FILTRATION EFFICIENCY (PFE)
Particulate Filtration Efficiency (PFE) material filters >99% of particles greater than 0.1 microns.
PFE measures the effectiveness of the mask material to filter particulate matter. This is the reason that all masks should be worn only once and disposed of. The filter matter loses efficiency over extended periods of time.
BREATHABILITY – DIFFERENTIAL PRESSURE
The mask design provides excellent breathability and low delta P ensuring coolness and comfort even when worn for an extended periods.
Delta P, Differential Pressure is a test that measures the breathability of mask materials, ranking masks on comfort and coolness. The lower the figure, the cooler and more comfortable the mask.
The Fluid Resistant three-ply layer design provides optimum fluid resistance thus further minimising the risk of infection dissemination.
Fluid resistance is measured in accordance with ASTM F2101-15 | EN 14683:2014 standard test method for resistance of medical face masks to penetration by synthetic blood at 16.0k Pa pressure.
