What is EN 1822 High efficiency air filters (EPA, HEPA and ULPA)?

EN 1822-High efficiency air filters is a European standard that specifies the testing and classification of high-efficiency air filters, including EPA (Efficiency Particulate Air), HEPA (High-Efficiency Particulate Air), and ULPA (Ultra-Low Penetration Air) filters. These filters are used in various applications to remove airborne particles and contaminants from the air, such as in cleanrooms, hospitals, pharmaceutical manufacturing, and HVAC (Heating, Ventilation, and Air Conditioning) systems.

Here’s a breakdown of what each type of filter is and its classification within the EN 1822 standard:
  1. EPA (Efficiency Particulate Air):
  • EPA filters are designed to remove a high percentage of airborne particles, including dust, pollen, and other pollutants.
  • The EN 1822 standard classifies EPA filters into different efficiency classes based on their ability to capture particles of different sizes. These classes are typically designated as E10, E11, and E12, with E12 being the highest efficiency class.
  1. HEPA (High-Efficiency Particulate Air):
  • HEPA filters are a subset of EPA filters known for their exceptional efficiency in removing very small particles, including bacteria, viruses, and sub-micron particles.
  • EN 1822 further classifies HEPA filters into three main categories: H13, H14, and U15. H14 is the most common class used in critical applications where high cleanliness is required, such as pharmaceutical cleanrooms and hospital operating rooms.
  1. ULPA (Ultra-Low Penetration Air):
  • ULPA filters are designed for the most demanding cleanroom environments where extremely high levels of air cleanliness are required. They are capable of removing even smaller particles than HEPA filters.
  • EN 1822 classifies ULPA filters into three main categories: U15, U16, and U17, with U17 being the highest efficiency class. These filters are used in industries like semiconductor manufacturing, aerospace, and nanotechnology research.
Overall, the classification of filters in EN 1822 is based on their ability to remove particles of varying sizes from the air. The testing procedures involve challenging the filters with specific aerosols and measuring their efficiency in removing particles of different sizes. The standard ensures that filters are accurately rated and can be trusted for their stated performance.

It’s important to note that EN 1822 is a European standard, and similar standards exist in other regions, such as the United States (e.g., ASME AG-1 for nuclear facilities) and global standards (e.g., ISO 29463 for particulate air filters). These standards provide guidance and certification for the performance of air filtration systems to maintain air quality and cleanliness in various critical applications.

What are the requirements for EN 1822 High efficiency air filters (EPA, HEPA and ULPA)?

EN 1822-High efficiency air filters sets requirements and testing methods for high-efficiency air filters, including EPA (Efficiency Particulate Air), HEPA (High-Efficiency Particulate Air), and ULPA (Ultra-Low Penetration Air) filters. The standard defines specific criteria and procedures to determine the performance and efficiency of these filters.

Here are some key requirements and testing parameters for EN 1822-compliant filters:
  1. Efficiency Testing:
  • Filters are tested for their ability to remove particles of various sizes from the air. These tests use aerosol challenges with known particle sizes.
  • Efficiency is typically reported for particle sizes of 0.3 micrometers (μm), 0.4 μm, and 0.5 μm, as these are critical sizes for filter performance.
  1. Leakage Testing:
  • EN 1822 requires testing for filter leaks to ensure that air does not bypass the filter media. Leakage testing is performed using a test aerosol and specific measurement techniques.
  1. Flow Rate Testing:
  • The standard specifies the airflow rate at which filters should be tested. This rate is typically expressed in cubic meters per hour (m³/h).
  1. Filter Classification:
  • Filters are classified into efficiency classes based on their performance. The classification includes categories such as E (EPA), H (HEPA), and U (ULPA) followed by a numerical designation.
  • EPA filters (E) are further divided into E10, E11, and E12.
  • HEPA filters (H) are classified as H13 and H14.
  • ULPA filters (U) are classified as U15, U16, and U17.
  1. Minimum Efficiency Requirement:
  • Each class of filter (EPA, HEPA, ULPA) has a minimum efficiency requirement for particles of different sizes. For example, HEPA H14 filters must have a minimum efficiency of 99.995% for 0.3 μm particles.
  1. Pressure Drop:
  • EN 1822 specifies the maximum allowable pressure drop across the filter at the rated flow rate. This ensures that filters do not excessively restrict airflow.
  1. Filter Integrity Testing:
  • Filters may be subjected to integrity testing, which involves testing for leaks and evaluating the filter’s overall performance.
  1. Marking and Labeling:
  • Filters that meet the requirements of EN 1822 are typically marked and labeled to indicate their efficiency class and other relevant information.
  1. Filter Documentation:
  • Manufacturers are required to provide documentation that includes information on filter performance, construction, and test results.
  1. Production Quality Control:
  • Manufacturers must establish and maintain quality control procedures to ensure that the filters they produce consistently meet the specified requirements.

In summary, EN 1822 is a comprehensive standard that ensures the performance and quality of high-efficiency air filters used in various critical applications, including cleanrooms, pharmaceutical manufacturing, and healthcare facilities. Compliance with this standard helps ensure that filters reliably provide the required level of air cleanliness and particle removal efficiency. Manufacturers of these filters typically have their products independently tested and certified to demonstrate compliance with EN 1822 and other relevant standards.
