High-efficiency particulate air (헤파) filters play a critical role in industries such as cleanrooms, pharmaceuticals, healthcare, 전자제품 제조. Ensuring their performance requires precise and reliable testing equipment. 하지만, with various testing standards and equipment types available, selecting the right HEPA filter testing system can be challenging.
This guide explains how to choose the most suitable HEPA filter testing equipment for accurate and consistent results.
1. Understand Relevant Testing Standards
Before selecting equipment, it is essential to identify which standards you need to comply with:
- 안에 1822 – European standard for HEPA/ULPA filter classification
- ISO 29463 – International standard aligned with EN 1822
- IEST-RP-CC001 – Commonly used in the U.S. for HEPA filter leak testing
Different standards require different test methods, especially for:
- 여과 효율
- 누출 감지 (scan test)
- 입자 크기 측정 (most penetrating particle size, MPPS)
👉 Choosing equipment that supports these standards is the first step toward accurate testing.
2. Key Parameters to Consider
When evaluating HEPA filter testing equipment, focus on these core parameters:
🔹 Filtration Efficiency
Measures how effectively the filter captures particles, typically at 0.1–0.3 μm.
🔹 Resistance (압력 강하)
Indicates airflow resistance, directly impacting system energy consumption.
🔹 Leak Detection Capability
Critical for HEPA filters, especially in cleanroom applications. Even minor leaks can compromise performance.
🔹 Particle Counting Accuracy
High-precision particle counters are essential for reliable results.
