    4.Remarks on Standards *ASTM = ASTM F2100 -11
    *BFE = Bacteria Filtration Efficiency, Size of typical bacteria at 3-5 microns
    *Delta P = Differential Pressure, Breathability - Pressure Difference, the smaller the value, the better
    *Fluid Resistance = Measure the ability to resist fluids at a specified pressure ( level 1 = 80mmHg, Level 2 = 120 mmHg, level 3 = 160 mmHg)
    *PFE = Particulate Filtration Efficiency, Particle size at 0.1 micron

    N95 is a rating given by The National Institute for Occupational Safety and Health (NIOSH) to any respirator that can filter out at least 95% of polluted particles.
    ASTM stands for the American Society for Materials and Testing, and ASTM F2100 -11 is a standard specification for performance of materials used in medical face masks. Materials used in medical face masks can be classified into 3 grades: Grade 1 is ideal for low amounts of fluid, spray and/or aerosols are produced; Grade 2 and 3 are for moderate to heavy amounts of fluid respectively. The main difference is fluid resistance.
    EN14683 is a European standard of requirements and test methods for medical face masks . It is divided into Type 1, 2 and 2R respectively. The main difference between Type 1 and 2 is BFE. And, Type 2 and 2R differ from each other in fluid resistance and breathability.
