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:
- OIN 16890
- DANS 1822
- OIN 5011
- OIN 29461-1:2021
1. Why Different Standards Exist
Air filters are used in very different environments:
- Buildings (CVC)
- Cleanrooms
- Engines
- Industrial systems
👉 Each application requires a specific testing approach
2. Overview of Major Standards
| Standard | Application | Key Focus |
|---|---|---|
| OIN 16890 | HVAC ventilation | PM-based efficiency |
| DANS 1822 | HEPA/ULPA filters | MPPS + leak testing |
| OIN 5011 | Engine filters | Dust loading + durability |
| OIN 29461-1 | Industrial intake | Real-condition simulation |
3. OIN 16890: HVAC Filter Testing

6. OIN 29461-1: Industrial Air Intake Filters
OIN 29461-1:2021 is used for large-scale industrial systems.
Key Features:
- PM-based efficiency
- Long-term dust loading
- Simulation of real conditions
👉 Typical applications:
- Gas turbines
- Power plants
- Industrial compressors
7. How to Choose the Right Standard
Choosing the correct standard depends on your application:
| Application | Recommended Standard |
|---|---|
| HVAC systems | OIN 16890 |
| Salle blanche / HEPA | DANS 1822 |
| Engine filters | OIN 5011 |
| Industrial intake | OIN 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:
- OIN 16890 → PM-based test rigs
- DANS 1822 → scanning leak test systems
- OIN 5011 → dust loading test benches
- OIN 29461-1 → high-capacity industrial systems
👉 Equipment must match the standard and application
