ايزو 16890 is an international standard used to classify general ventilation air filters based on their efficiency in removing particulate matter from the air. Unlike earlier standards that relied on laboratory particle sizes, ايزو 16890 evaluates filter performance using particle size ranges that correspond to real atmospheric particulate matter, including PM1, PM2.5, and PM10.
“This approach provides a more realistic assessment of filter performance in actual operating environments.“
الأيزو 16890 classification system is based on three particulate matter fractions.
| تصنيف | نطاق حجم الجسيمات |
| ePM1 | particles ≤ 1 ميكرومتر |
| ePM2.5 | particles ≤ 2.5 ميكرومتر |
| ePM10 | particles ≤ 10 ميكرومتر |
These categories correspond to commonly used air quality indicators for airborne particles. The efficiency reported for each category represents the average removal efficiency of particles within the defined size range.
The test procedure defined in ISO 16890 includes several steps:
These steps ensure that filters relying on electrostatic charges are evaluated under realistic long-term performance conditions.

Filter Class |
وصف |
|
ISO ePM1 |
high efficiency for fine particles |
|
ISO ePM2.5 |
moderate efficiency for fine particles |
|
ISO ePM10 |
efficiency for larger particles |
|
ISO الخشنة |
filters primarily removing large dust particles |
Stable and repeatable measurement conditions are essential to ensure that efficiency results reflect actual filter performance. ايزو 16890 is widely used for testing filters applied in ventilation systems, مشتمل:
Filtration testing systems designed for ISO 16890 procedures typically support:
These systems enable laboratories and manufacturers to perform reliable filter verification according to international standards.
