ISO 16890 represents the current global standard for air filtration testing, replacing older regional standards with a unified methodology. This standard evaluates filter performance against particle size ranges that correlate with real-world air quality impacts, including PM1, PM2.5, and PM10 particles.
The ISO testing protocol requires filters to undergo conditioning cycles that simulate months of operation, ensuring performance ratings reflect long-term rather than initial capabilities. Filters receive efficiency ratings in four categories: coarse particles (PM10), medium particles (PM2.5), fine particles (PM1), and ultra-fine particles below 0.3 microns.
HEPA and ULPA Filter Classifications
High-Efficiency Particulate Air (HEPA) and Ultra-Low Particulate Air (ULPA) filters represent the highest tier of certified filtration technology. HEPA filters must demonstrate minimum 99.97% efficiency for 0.3-micron particles, while ULPA filters achieve 99.999% efficiency for the same particle size.
These classifications involve extensive testing protocols that evaluate not only initial efficiency but also structural integrity, pressure drop characteristics, and performance degradation over time. The testing process typically requires 72-96 hours of continuous operation under controlled conditions.
| Filter Class | Efficiency Requirement | Typical Pressure Drop | Primary Applications |
|---|---|---|---|
| HEPA H13 | 99.95% @ 0.3μm | 200-300 Pa | Medical, Clean Manufacturing |
| HEPA H14 | 99.995% @ 0.3μm | 250-350 Pa | Pharmaceutical, Semiconductor |
| ULPA U15 | 99.9995% @ 0.3μm | 300-400 Pa | Nanotechnology, Research |
