Summary table of the filters classification according to the performance, as described in the European Standard EN779:2012 “Particulate air filters for general ventilation” concerning the performance air filters must meet.
The EN 779 Standard is based on laboratory test (made with test aerosols and test dusts) so the results are transferable to actual applications only with very restricted relevance.
The principal results of the EN 779 Standard laboratory test are:
- Gravimetric arrestance efficiency for synthetic dust
- Efficiency: corresponds to the number-referenced fractional collection efficiency for 0.4 μm particles of the synthetic test aerosol
- Pressure Drop
- Dust holding capacity for synthetic dust
| Class | Pressure Drop | Average Arrestance Am | Average Efficiency Em | Minimum Efficiency | |
|---|---|---|---|---|---|
| Coarse Dust Filters | G1 | 250 Pa | 50% ≤ Am < 65% | – | – |
| G2 | 250 Pa | 65% ≤ Am < 80% | – | – | |
| G3 | 250 Pa | 80% ≤ Am < 90% | – | – | |
| G4 | 250 Pa | 90% ≤ Am | – | – | |
| Fine Dust Filters (0,4 µ particles) | M5 | 450 Pa | – | 40% ≤ Em < 60% | – |
| M6 | 450 Pa | – | 60% ≤ Em < 80% | – | |
| F7 | 450 Pa | – | 80% ≤ Em < 90% | 35% | |
| F8 | 450 Pa | – | 90% ≤ Em < 95% | 55% | |
| F9 | 450 Pa | – | 95% ≤ Em | 70% |
