Air filtration plays a critical role in maintaining indoor air quality across HVAC systems, industrial environments, and commercial buildings. To ensure reliable performance, general air filters must be evaluated according to standardized testing methods and classification systems.
This article provides an overview of testing standards, filter classification, and test rig systems, helping manufacturers and laboratories select the right solutions for performance validation.
1. What Are General Air Filters?
General air filters are primarily used in HVAC and ventilation systems to remove airborne particles such as:
- Dust
- Pollen
- Fine particulate matter (PM10, PM2.5, PM1)
Unlike HEPA filters, general ventilation filters focus on real-world particle size distribution, making their testing standards more application-oriented.
2. Key Testing Standards for General Air Filters
2.1 ISO 16890
그만큼 ISO 16890 standard is currently the most widely adopted global standard for general ventilation filters.
주요 기능:
- Classifies filters based on PM1, PM2.5, PM10 효율
- Reflects real atmospheric dust conditions
- Replaces older standards like EN 779
분류 시스템:
- ePM1
- ePM2.5
- ePM10
- 조잡한
👉 This standard provides a more realistic evaluation compared to traditional methods.
2.2 안에 779 (레거시 표준)
안에 779 was previously used in Europe, classifying filters as:
- G1~G4 (거친 필터)
- F5~F9 (미세 필터)
Although now largely replaced by ISO 16890, it is still referenced in some markets and legacy systems.
3. Filter Classification Overview
Modern classification focuses on particle size efficiency, rather than only arrestance:
| 분류 | 입자 크기 범위 | 애플리케이션 |
|---|---|---|
| 조잡한 | >10 μm | 사전 여과 |
| ePM10 | 10μm 이하 | Commercial HVAC |
| ePM2.5 | 2.5μm 이하 | Indoor air quality control |
| ePM1 | 1μm 이하 | High-performance ventilation |
This shift allows engineers to better match filters with real environmental requirements.
4. Test Methods and Key Parameters
To evaluate general air filters, several parameters are measured:
4.1 여과 효율
- Based on particle size distribution
- Measured across multiple size ranges
4.2 압력 강하
- 공기 흐름 저항을 나타냅니다.
- Directly impacts energy consumption
4.3 먼지 보유 용량
- Determines service life
- Evaluated through loading tests
4.4 Discharge/Conditioning Process
- Required in ISO 16890
- 실제 작동 조건을 시뮬레이션합니다.
5. Test Rig Systems for Air Filter Evaluation
A complete air filter test system typically includes:
- 에어로졸 생성 시스템
- Particle measurement instruments
- 기류 제어 시스템
- 먼지 공급 시스템
- 데이터 수집 소프트웨어
These systems must provide:
✔ Stable airflow control
✔ Accurate particle measurement
✔ Repeatable test conditions
