PQM FreedomAIR
Analyzed by SGS
Fluid Resistance - Mask resistance to penetration by synthetic blood under pressure (mmHg). Higher resistance = higher protection
PFE- Particle Filtration Efficiency - Percentage of particles filtered out at a pore size of 0.1 - 1.0 microns (µ).
BFE – Bacteria Filtration Efficiency - Percentage of particles filtered out at a pore size of 1.0 - 5.0 microns (µ).
DeltaP - Differential Pressure - Pressure drop across mask, or resistance to airflow in mmH2O/cm² . Greater resistance = better protection but less breathability.
FlameSpread- Measures the flame spread of the mask material (Flammability)
Independent Laboratory Testing Conducted by SGS
SGS is the world’s leading inspection, testing and certification company. They have comprehensive techniques for testing non-woven fabrics specific for the medical industry.
The following tests have been conducted externally on PQM FreedomAIR civilian grade face masks.
Below are extractions from the Official SGS report.
