For filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols(e.g. viruses). However, prior to selecting a respirator,users should consult their local respiratory protection regulations and requirements or check with their local public health authorities for selection guidance.


This introduce is only intended to help clarify some key similarities between such references, specifically to the following FFR(Filtering facepiece respirators)
performance standards:
• N95 (United States NIOSH-42CFR84)
• FFP2 (Europe EN 149-2001)
• KN95 (China GB2626-2006)
• P2 (Australia/New Zealand AS/NZA 1716:2012)
• Korea 1 st class (Korea KMOEL - 2017-64)
• DS (Japan JMHLW-Notification 214, 2018)

Definitions:
Filter performance – the filter is evaluated to measure the reduction in concentrations of specific aerosols in air that passes through the filter.

Test agent - the aerosol that is generated during the filter performance test.

Total inward leakage (TIL) – the amount of a specific aerosol that enters the tested respirator facepiece via both filter penetration and faceseal leakage, while a wearer performs a series of exercises in a test chamber.

Inward leakage (IL)– the amount of a specific aerosol that enters the tested respirator facepiece, while a wearer performs a normal breathing for 3 minutes in a test chamber. The test aerosol size (count median diameter) is about 0.5 micro meter.

Pressure drop – the resistance air is subjected to as it moves through a medium, such as a respirator filter.
US: N95 is based on the US criteria, which divides medical respirators into three categories, nine models. N refers to Non-oily particles, R and P refers to oily particles. Non-oily particles include dust, cement dust, acid mist, welding fumes, microorganisms; oily particles include Oil mist, soot, and coke oven smoke. Each mode has three filter grades (95%, 99% and 100%).
