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 (颗粒物10, PM2.5, 颗粒物1)
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 国际标准化组织 16890
这 国际标准化组织 16890 standard is currently the most widely adopted global standard for general ventilation filters.
主要特点:
- Classifies filters based on 颗粒物1, PM2.5, 和 PM10 效率
- Reflects real atmospheric dust conditions
- Replaces older standards like EN 779
分类系统:
- 电子PM1
- ePM2.5
- 电子PM10
- 粗
👉 This standard provides a more realistic evaluation compared to traditional methods.
2.2 在 779 (旧标准)
在 779 was previously used in Europe, classifying filters as:
- G1-G4 (粗过滤器)
- F5-F9 (精细过滤器)
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:
| 分类 | 粒径范围 | 应用 |
|---|---|---|
| 粗 | >10 微米 | 预过滤 |
| 电子PM10 | ≤10微米 | Commercial HVAC |
| ePM2.5 | ≤2.5微米 | Indoor air quality control |
| 电子PM1 | ≤1微米 | 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 过滤效率
- Based on particle size distribution
- Measured across multiple size ranges
4.2 压降
- 表示气流阻力
- Directly impacts energy consumption
4.3 容尘量
- Determines service life
- Evaluated through loading tests
4.4 Discharge/Conditioning Process
- Required in ISO 16890
- 模拟真实操作条件
5. Test Rig Systems for Air Filter Evaluation
A complete air filter test system typically includes:
- 气溶胶发生系统
- Particle measurement instruments
- 气流控制系统
- Dust feeding system
- 数据采集软件
These systems must provide:
✔ Stable airflow control
✔ Accurate particle measurement
✔ Repeatable test conditions
