The filters are placed in so-called ePM categories.
This classification gives an accurate indication of which particle sizes are filtered out of the air.
PM1 stands for all types of particulate matter ('ParticulateMatter') that are smaller than 1 micron (μ = one thousandth of a millimeter):
- PM1: 1μ = 0.001 mm
- PM2.5: 2.5μ = 0.0025 mm
- PM10: 10μ = 0.01mm
The 'e' for PM1 stands for 'efficiency' and indicates the efficiency of the air filter in capturing PM1.
Based on these values, the standard now divides filters into four groups that filter different dust particles:
- ISOCoarse< 50% (sand, fluff, hair)
- ISO ePM10 ≥ 50% (pollen, rock dust)
- ISO ePM2.5 ≥ 50% (mold traces, toner dust)
- ISO ePM1 (combustion particles, nanoparticles, viruses)
