Filtration: ISO 16890 Part 1 filter testing
ISO 16890-aligned testing for general ventilation filter media, complete filter assemblies, and ePM performance programs.
Use this cluster when filter development, claims, or technical documentation require evidence for ePM1, ePM2.5, ePM10, fractional efficiency, resistance, conditioning, or dust loading.
Standard roster
Individual standards in this cluster
ISO 16890-1, ISO 16890-2, ISO 16890-3, and ISO 16890-4 form the citation set; ARE Labs maps them to filter classification, fractional efficiency, dust loading, conditioning review, QA records, and report outputs.
ISO 16890 Part 2
ISO 16890 Part 2 controls the measurement frame for fractional efficiency and air flow resistance.
AlignedISO 16890 Part 3
ISO 16890 Part 3 applies when a program needs gravimetric efficiency and air flow resistance versus captured test dust mass.
AlignedISO 16890 Part 4
ISO 16890 Part 4 addresses conditioning used to determine minimum fractional test efficiency.
AlignedPurpose & when to use
ISO 16890 evaluates general ventilation filters based on particulate matter efficiency, fractional efficiency, resistance to air flow, dust loading, and the effects of conditioning. This Standards cluster helps teams determine whether an ISO 16890-aligned plan can support filter media comparisons, HVAC filter development, product claims, supplier reviews, or documented evidence for ePM1, ePM2.5, and ePM10 performance.
- Filter developers use ISO 16890 Part 1 when ePM classification language must connect efficiency data, product marking, and documentation expectations.
- Engineering teams use ISO 16890 Part 2 when fractional efficiency and air flow resistance need particle-size-resolved evidence from controlled runs.
- Dust-loading programs use ISO 16890 Part 3 when gravimetric efficiency, captured test dust mass, and resistance trends affect claims.
- Electrostatically charged media programs use ISO 16890 Part 4 when conditioning and minimum fractional test efficiency need reviewable support.
- Nonstandard air-cleaning products use ISO 16890 as context when ARE Labs must document deviations from filter-element assumptions.
Use this cluster when the question extends beyond whether a filter removes particles. It helps determine whether the method, fixture, challenge aerosol, conditioning state, calculations, and report language can be reviewed against the ISO 16890 series.
Applicable to
Built around ventilation filter decisions
The cluster applies when filter performance depends on controlled air flow, particle-size-resolved challenge measurement, pressure drop, loading behavior, and documentation of product format limits.

What each citation controls
This page treats ISO 16890 as a standards cluster. Part 1 supplies the classification frame, Part 2 covers fractional efficiency and resistance measurement, Part 3 addresses gravimetric dust-loading behavior, and Part 4 addresses conditioning for minimum fractional efficiency. ARE Labs uses the series as an aligned method family, not a certification claim.

Operational chain
How ARE Labs turns the standards into a study
The ISO 16890 series sets the reference frame, but the executable plan still depends on filter format, face velocity, fixture geometry, challenge aerosol, sampling instruments, and the decision the data must support.
01
Configuration
Map the filter to the ISO frame
ARE Labs compares the product format against ISO 16890 assumptions before selecting fixture geometry, air flow, challenge aerosol, and sampling points.
Protocol setup02
Measurement
Control particle and pressure data
ISO 16890 Part 2 runs tie upstream and downstream particle measurements to pressure drop, background checks, sampling timing, and instrument records.
Run record03
Loading
Track dust and resistance behavior
ISO 16890 Part 3 programs document dust addition, captured mass context, balance records, pressure trend review, and stop conditions.
Loading log04
Conditioning
Record minimum-efficiency context
When ISO 16890 Part 4 is relevant, ARE Labs records conditioning state, media handling, rationale, and limits on interpretation.
Conditioning note05
Reporting
Connect results to claims
Reports connect ISO 16890 ePM language, fractional efficiency, penetration, resistance, deviations, QC checks, and calculation workbooks.
Review-ready reportData quality, QA/QC & documentation
Defensible ISO 16890-aligned filter testing depends on controlled methods and complete records, not only the reported efficiency. ARE Labs documents the fixture setup, background particle levels, flow and pressure sensors, challenge stability, filter orientation, conditioning state, raw instrument files, calculations, deviations, and review records.
Link setup to ISO scope
ISO 16890 records connect filter identification, orientation, fixture setup, flow condition, and sampling locations to the selected method frame.
Preserve calibrated measurements
ISO 16890 Part 2 studies retain particle counter or sizer files, pressure sensor records, flow meter references, and calibration status.
Document mass and resistance
ISO 16890 Part 3 programs retain dust-loading observations, balance records, resistance trends, and calculation workbooks for review.
Show media state
ISO 16890 Part 4 records describe conditioning state, sample handling, applicable limits, and the effect on minimum-efficiency interpretation.
Separate claims from data
ISO 17025 aligned review checks that reports state methods, deviations, uncertainty notes, and certification limits plainly.
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 help filter developers, HVAC teams, and air-cleaning manufacturers determine whether a project belongs under ISO 16890, an adjacent filtration standard, or a fit-for-purpose protocol. The answers outline the scoping decisions ARE Labs resolves before preparing the method, acceptance criteria, evidence records, and report package.
Q. Which part applies?
A. ISO 16890-1 defines the classification framework. Part 2 addresses fractional efficiency and resistance, Part 3 addresses dust-loading behavior, and Part 4 addresses conditioning used to determine minimum fractional efficiency.
Q. Does ARE Labs certify filters?
A. No. ARE Labs performs ISO 16890-aligned testing when applicable, but certification, listing, or formal approval must come from the relevant certification body or authority.
Q. Are room air cleaners included?
A. ISO 16890 publisher materials exclude portable room-air cleaner elements from the standard's direct scope. ARE Labs may still reference the series when documenting a separate protocol.
Q. What if the fixture differs?
A. Before reporting, ARE Labs documents any departures from ISO 16890 assumptions, including differences in geometry, air flow, sampling location, conditioning state, and interpretation limits.
Q. What data do clients receive?
A. Typical outputs include fractional efficiency, penetration, ePM-related calculations, pressure drop, dust-loading observations, raw data references, QC checks, plots, and a record of documented deviations.
