Understanding ASTM Performance Standards
ASTM is an international testing organization that sets performance criteria based on a number of characteristics including filtration efficiency. Masks that don't have an ASTM performance level on the packaging have not been certified and their true filtration efficiency is unknown.
|Criteria||Non-Certified||Level 1||Level 2||Level 3|
|Filtration Efficiency, BFE||Unknown||≥95%||≥98%||≥98%|
|Filtration Efficiency, PFE||Unknown||≥95%||≥98%||≥98%|
|Fluid Resistance, mmHg||Unknown||80||120||160|
|Breathability - Delta P||Unknown||<4.0||<5.0||<5.0|
|Flame Spread||Unknown||Class 1||Class 1||Class 1|
Filtration Efficiency, BFE - Percentage of aerosol particles filtered at a size of 3 microns.
Filtration Efficiency, PFE - Percentage of submicron particles filtered at 0.1 microns.
Fluid Resistance, mmHg - Mask resistance to penetration by synthetic blood under
pressure (mmHg). A higher fluid resistance provides higher protection.
Breathability - Delta P - Pressure drop across mask, or resistance to air flow in mmH2O/cm2. Greater resistance provides better filtration, but less breathability.
Flame Spread - Measures the flame spread of the mask material.
VetMed Solutions only offers ASTM Level 2 and 3 certified disposable masks to provide a filtration efficiency of ≥ 98%.
