Air filter testing standards vary depending on application, filter type, and performance requirements.
From HVAC systems to industrial air intake and engine filtration, different standards define how filters should be evaluated.
This article provides a complete overview of the most important standards:
- ISO 16890
- 안에 1822
- ISO 5011
- ISO 29461-1:2021
1. Why Different Standards Exist
Air filters are used in very different environments:
- Buildings (공조)
- 클린룸
- Engines
- Industrial systems
👉 Each application requires a specific testing approach
2. Overview of Major Standards
| 기준 | 애플리케이션 | Key Focus |
|---|---|---|
| ISO 16890 | HVAC ventilation | PM-based efficiency |
| 안에 1822 | HEPA/ULPA filters | MPPS + 누출 테스트 |
| ISO 5011 | Engine filters | 먼지 로딩 + durability |
| ISO 29461-1 | Industrial intake | Real-condition simulation |

7. How to Choose the Right Standard
Choosing the correct standard depends on your application:
| 애플리케이션 | Recommended Standard |
|---|---|
| HVAC 시스템 | ISO 16890 |
| 클린룸 / 헤파 | 안에 1822 |
| Engine filters | ISO 5011 |
| Industrial intake | ISO 29461-1 |
👉 Using the wrong standard can lead to:
- Inaccurate results
- Misleading performance evaluation
- Increased costs
8. Testing Equipment Considerations
Each standard requires different testing systems:
- ISO 16890 → PM-based test rigs
- 안에 1822 → scanning leak test systems
- ISO 5011 → dust loading test benches
- ISO 29461-1 → high-capacity industrial systems
👉 Equipment must match the standard and application
