EN 1822

In the quest for clean air, high-efficiency filters play a vital role. But how can we be sure they deliver on their promises? Enter EN 1822, a European standard that raises the bar for air filtration quality, ensuring the performance and reliability of these crucial devices.

Key Focus Areas of EN 1822:

• Scope:
  • Applies to high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters, designed to capture the tiniest airborne particles.
  • Used in diverse settings, from hospitals and cleanrooms to homes and vehicles.
• Classification System:
  • Establishes a comprehensive classification system based on filter efficiency, ranging from E10 to U17:
    • E10 to H14: HEPA filters, capturing 85% to 99.995% of particles down to 0.3 microns.
    • U15 to U17: ULPA filters, capturing 99.9995% to 99.999995% of particles down to 0.12 microns.
• Testing Procedures:
  • Outlines rigorous testing methods to verify filter efficiency and performance under real-world conditions.
  • Involves challenging filters with a range of particle sizes and concentrations.
  • Ensures consistent and reliable performance across different manufacturers.
• Labeling Requirements:
  • Mandates clear labeling of filters with their EN 1822 classification, ensuring informed choices for consumers and professionals.

Benefits of Compliance:

• Confidence in Filtration Performance:
  • Guarantees filters meet their stated efficiency claims.
  • Provides assurance of effective air cleaning in sensitive environments.
• Enhanced Product Quality:
  • Drives manufacturers to create filters that meet stringent standards.
  • Promotes innovation and advancement in filtration technology.
• Greater Transparency:
  • Enables users to easily compare and select filters based on their needs.
  • Fosters trust and reliability in the air filtration industry.

Overall Significance:

• EN 1822, while European in origin, serves as a global benchmark for air filtration quality.
• Frequently referenced in international regulations and guidelines.
• Contributes to cleaner air, healthier environments, and enhanced protection against airborne contaminants.

In essence, EN 1822 stands as a testament to the pursuit of cleaner air and healthier spaces. Its meticulous standards ensure the effectiveness of air filters, safeguarding our health and well-being in a world increasingly concerned with air quality.
