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%.
