HEPA/ULPA Filtration: EN 1822 / ISO 29463
Standards cluster for MPPS-focused HEPA and ULPA filter efficiency, penetration, and pressure-drop studies.
Use it when high-efficiency filter data must connect EN 1822 or ISO 29463 method choices, aerosol challenge controls, sampling records, and reportable efficiency evidence.

AlignedPurpose & when to use
HEPA and ULPA filter programs use EN 1822 and ISO 29463 when the critical decision is particle penetration at or near the most penetrating particle size. This cluster helps teams frame method selection, aerosol challenge conditions, upstream and downstream measurement, pressure-drop tracking, repeatability, and documentation without treating ARE Labs testing as product certification:
- Filter media teams use ISO 29463 and EN 1822 to compare penetration, efficiency, and pressure drop under MPPS challenge conditions.
- HEPA/ULPA element programs use ISO 29463 when classification support data must connect particle counting, leakage, and report documentation.
- Air-treatment devices use ISO 29463 and EN 1822 context when installed filter modules need fixture-specific performance evidence.
- Development programs use ISO 29463 framing to document nonstandard geometry, airflow limits, deviations, and acceptance criteria.
Use this cluster when the question is whether high-efficiency filtration evidence can be traced from aerosol generation and particle sizing through concentration measurements, operating conditions, calculations, deviations, and final report interpretation.
Applicable to
Built around high-efficiency filter decisions
The cluster applies when EPA, HEPA, or ULPA performance depends on MPPS targeting, upstream/downstream sampling, pressure drop, and traceable fixture or device configuration.

What each citation controls
This page is a standards cluster, not a certification page or a reproduction of protected standard text. EN 1822 and ISO 29463 give the high-efficiency filter frame for classification, performance testing, marking, particle measurement, and documentation. ARE Labs uses them to build protocol controls and report evidence for product development, validation, and claims support.

Operational chain
How ARE Labs turns the standards into a study
The standards set the filter-performance frame, but the executable method still depends on filter format, airflow range, fixture interface, aerosol source, particle measurement path, and client decision.
01
Configuration
Map the filter and fixture
We translate EN 1822 or ISO 29463 into a fixture plan covering filter orientation, seal approach, airflow range, pressure taps, and sampling locations.
Protocol setup02
Challenge
Target the MPPS region
Aerosol generation, particle sizing, background control, and upstream concentration checks are selected to support the EN 1822 or ISO 29463 decision point.
Challenge record03
Measurement
Capture penetration evidence
Upstream and downstream particle measurements, airflow, pressure drop, temperature, humidity, and run timing are recorded against the ISO 29463 or EN 1822 frame.
Traceable run log04
Adaptation
Document nonstandard devices
When a housing, purifier, duct, or respirator component does not match EN 1822 fixtures, ARE Labs records the ISO 29463 rationale and limits.
Adaptation rationale05
Reporting
Connect results to reviewable evidence
Reports connect EN 1822 or ISO 29463 citations to efficiency, penetration, pressure drop, conditions, calculations, deviations, and method limitations.
Review-ready reportData quality, QA/QC & documentation
High-efficiency filter results depend on stable challenge conditions, traceable measurements, and transparent calculations. ARE Labs ties EN 1822 and ISO 29463 study framing to fixture records, instrument checks, raw particle data, pressure-drop evidence, deviations, and QA review so the client can see how each result was produced.
Connect setup to citation
EN 1822 and ISO 29463 runs link fixture configuration, filter orientation, airflow, pressure drop, and sampling locations to the chosen study frame.
Preserve run conditions
ISO 29463 documentation keeps aerosol generation, particle sizing, background control, temperature, humidity, and challenge stability visible in the review trail.
Retain raw and reduced data
ISO 29463 / EN 1822 data packages retain upstream and downstream particle results, efficiency, penetration, pressure drop, calculations, and instrument references.
Document method decisions
When product geometry falls outside EN 1822 or ISO 29463 assumptions, ARE Labs records the rationale, limitation, and interpretation impact.
Separate alignment from certification
ISO 17025 review distinguishes ARE Labs test evidence from third-party certification, product listing, or regulatory approval.
Why ARE Labs
ARE Labs connects technical topics to practical study design, method selection, controlled aerosol work, and reportable evidence without turning technical pages into sales pages.

Common questions
These questions cover how product, quality, and regulatory teams decide whether HEPA or ULPA filter work belongs under EN 1822, ISO 29463, or a fit-for-purpose protocol. The answers separate standards-aligned testing from certification and identify the records ARE Labs typically prepares before final technical reporting.
Q. Which standard applies?
A. EN 1822 and ISO 29463 are both used for high-efficiency EPA, HEPA, and ULPA filters. The choice depends on product form, target market, claim language, and whether the program needs classification support, penetration data, leak context, or development evidence.
Q. Does ARE Labs certify HEPA filters?
A. No. ARE Labs performs testing aligned with the cited standard where applicable. Certification, listing, or formal product classification may require review by a separate authority or certification body.
Q. What if my device is not a standard filter?
A. ARE Labs can build a fit-for-purpose protocol for purifiers, duct systems, respirator components, or nonstandard housings. The protocol and report document deviations, rationale, and interpretation limits.
Q. What data does the report include?
A. Reports can include fixture details, operating conditions, upstream and downstream particle results, efficiency, penetration, pressure drop, calculations, calibration references, QC checks, deviations, and data exclusions.
Q. Why are publisher links included?
A. Official BSI and ISO links let clients confirm the exact standard family, status, scope, and purchase source without relying on unofficial copies or summaries.
