High efficiency air filters (EPA, HEPA and ULPA) - Part 1: Classification, performance testing, marking

This document applies to high efficiency particulate and ultra-low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry.
It establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency.

Dieses Dokument gilt für Hochleistungs-Partikelfilter und Hochleistungs-Schwebstofffilter (EPA, HEPA und ULPA) im Bereich der Raum- und Prozesslufttechnik, z. B. Anwendungen in der Reinraumtechnik oder in der pharmazeutischen Industrie.
Es legt ein Verfahren zur Prüfung des Abscheidegrades auf Basis von Partikelzählverfahren unter Verwendung eines flüssigen (oder alternativ eines festen) Prüfaerosols fest und ermöglicht eine einheitliche Klassifizierung der Schwebstofffilter nach dem Abscheidegrad, sowohl nach dem integralen als auch nach dem lokalen Abscheidegrad.

Filtres à air à haute efficacité (EPA, HEPA et ULPA) - Partie 1 : Classification, essais de performance et marquage

Le présent document s'applique aux filtres à air à très haute efficacité et à très faible pénétration (EPA, HEPA et ULPA) utilisés dans le domaine de la ventilation et du conditionnement d'air, ainsi que dans des procédés techniques, par exemple pour des applications relevant de la technique des salles blanches ou de l’industrie pharmaceutique.
Il définit un mode opératoire de détermination de l’efficacité à partir d’une méthode de comptage des particules à l’aide d’un aérosol d’essai liquide (ou solide) et permet une classification normalisée de ces filtres en fonction de leur efficacité, à la fois locale et globale.

Ta evropski standard se uporablja za visoko učinkovite zračne filtre drobnih delcev in zračne filtre z ultra nizko penetracijo (EPA, HEPA in ULPA), ki se uporabljajo na področju prezračevanja in klimatizacije ter za tehnične postopke, npr. za naprave v tehnologiji čistega prostora ali farmacevtski industriji.
Vzpostavlja postopek za določitev učinkovitosti na osnovi metode štetja delcev z uporabo tekočega preskusnega aerosola (ali v trdnem stanju kot druga možnost) ter omogoča standardizirano klasifikacijo teh filtrov glede na njihovo (lokalno in celostno) učinkovitost.

Overview

EN 1822-1:2019 is the CEN European standard that defines classification, performance testing and marking for high efficiency air filters - EPA, HEPA and ULPA - used in ventilation, air conditioning and technical processes (for example cleanrooms and pharmaceutical production). The standard establishes a particle-counting test procedure (liquid aerosol, alternatively solid for leak checks) to determine filter efficiency at the most penetrating particle size (MPPS) and to assign filters to standardized classes (E10–E12, H13–H14, U15–U17).

Key topics and technical requirements

• Scope & classification
  • Covers EPA, HEPA and ULPA filter elements and assigns groups/classes by integral and (for H and U) local MPPS efficiency/penetration.
  • Classes: E10–E12, H13–H14, U15–U17.
• Measurement basis
  • Particle-counting methods using a liquid test aerosol (e.g., DEHS, PAO, PSL). Solid aerosols allowed for some leak tests.
  • Determination of MPPS from sheet-media efficiency vs particle size curves.
• Three-step test process
  1. Flat sheet filter media test to determine MPPS and baseline efficiency.
  2. Leak test of the filter element (mandatory for Groups H and U; Group E not leak-tested for classification).
  3. Efficiency test of the assembled filter element at the nominal air volume flow rate.
• Test conditions
  • Typical test air temperature (23 ± 5) °C and relative humidity < 75%, with tighter stability during tests.
  • Clean test air (background particle concentration control - e.g., < 352,000 particles/m³).
• Performance metrics
  • Integral efficiency/penetration at MPPS and, for H/U groups, local (scan) leakage limits.
  • Special handling for electrostatically charged media - classification based on discharged efficiency (per EN ISO 29463-5).
• Documentation & marking
  • Test reports, marking and traceability requirements for manufacturers and testing laboratories.

Practical applications

• Specifying and verifying filters for:
  • Cleanrooms (semiconductor, biotech, medtech)
  • Pharmaceutical manufacturing and aseptic processing
  • Hospital HVAC and isolation rooms
  • Critical industrial processes requiring particle control
• Used by: filter manufacturers, independent test laboratories, HVAC engineers, cleanroom qualification teams, procurement/specification authors and regulatory bodies.

Who should use this standard

• Manufacturers for product classification and marking
• Test laboratories for accredited performance testing
• Engineers and facility managers for selecting and validating filters in controlled environments

Related standards

• EN ISO 29463-2 / -3 / -4 / -5 (aerosol production, sheet media testing, scan leak method, filter element testing)
• EN 14799 (terminology)
• EN ISO 5167-1, ISO 2859-1 (measurement & sampling references)

EN 1822-1:2019 supersedes EN 1822-1:2009 and emphasizes particle-counting methods (it excludes the aerosol-photometer scan leak test), making it the reference for modern HEPA/ULPA performance classification and testing.
