【Certification】Standard For Air Filtration ISO 16890-1

ISO 16890-1:2016




Key Points
  • Exits in parallel with EN779, until June 30, 2018
  • Shifts the focus on filtration performance to the classes of particulate matter size (PM)
  • Standard filter efficiency will be determined based on particulate matter size classes PM1, PM2.5 and PM10
  • A much more realistic test criteria than the theoretical EN779:2012
  • Same as the evaluation parameters by the WHO (World Health Organization) and other authorities
  • It will be easier for users to select the right air filter based on their requirements
The Benefits
  • 1

    One global international standard.

  • 2

    The ISO16890 records their performances at a particle spectrum of 0.3 up to 10 microns (versus the EN779 test which qualified fine filter performance at 0.4 microns

  • 3

    Fractional efficiancies of the filterprior to and after IPA diacharge of any eleotrostatic properties can be seen.

  • 4

    Filters can be chosen for their specific performance related to the need of the application.

ISO16890 standard divides air filters into four groups.


ePM1, min ≥ 50%
(viruses, nanoparticles, exhaust gasses)

ISO ePM2.5

ePM2.5, min ≥ 50%
(bacteria, fungal and mold spores, pollen, toner dust)


ePM10 ≥ 50%
(pollen, desert dust)

ISO coarse

ePM10 ≤ 50%
(sand, hair)

A prerequisite or each group is that a filter captures at least 50% of the appropriate particle size range If a filter, for example, capture more than 50% of PM1 particles it will be grouped as an ISO e PM1 filter The respective efficiency is then reported, rounded n5% increments.

A simple translation table between EN779 : 2012 and ISO 16890
