Replaces old EN 779 standards. Classifies media into ePM1 (>50%), ePM2.5 (>50%), ePM10 (>50%), and Coarse based on particle size separation capabilities.
Governs high efficiency HEPA and ULPA filters (E10-U17) testing local and overall penetration using MPPS (Most Penetrating Particle Size).
Media must display self-extinguishing properties under European fire codes to prevent rapid propagation within ventilation ducts.
CE optimized designs reduce aerodynamic resistance, minimizing electricity consumption by internal AHU fans and blowers.
Conventional fiberglass is increasingly replaced by synthetic composite roll media to eliminate fiber shedding risks in food processing and pharmaceuticals.
With increasing levels of airborne contaminants, systems are standardizing on ePM1 levels, calling for dual-phase meltblown matrices with electrostatic charges.
European HVAC installations require compliance with strict energy thresholds. High-efficiency, low-resistance filters reduce operational costs and help meet these targets.
| Filter Class (ISO 16890 / EN 779) | Material Configuration | Common Applications | Key Performance Indicators |
|---|---|---|---|
| Coarse / G3 - G4 | Polyester laminated wire mesh rolls | Pre-filtration in standard AHUs, air purifiers | High dust loading capacity, washability options | ePM10 / M5 - M6 | Pocket synthetic fibers | General ventilation, office buildings | Excellent medium particulate holding |
| ePM1 / F7 - F9 | Meltblown composites, multi-pocket bags | Hospitals, commercial centers, labs | >50% efficiency for particles under 1µm |
| HEPA / H13 - H14 | Mini-pleated fiberglass/Gel Seal compact | Clean rooms, operating rooms, microelectronics | >99.97% containment at 0.3µm particle sizes |
Requires ultra-low outgassing and high-rigidity mini-pleated HEPA filters with top-side gel seals to prevent particle infiltration into silicon processing environments.
Demands antiviral properties and high mechanical filtration efficiency (H13 or H14 rating) to manage biological aerosols and inhibit microbial growth.
Uses multi-pocket synthetic bags and G3/G4 pre-filter media rolls to manage high airflow, protect secondary filters, and maintain building air quality.
