ISO 16890 Part 1
ISO 16890 Part 1 frames general ventilation filter classification around ePM performance, general requirements, marking, and documentation.
AlignedISO 16890-aligned filtration testing for general ventilation filter media, assemblies, and ePM performance programs.
Use this cluster when ePM1, ePM2.5, ePM10, fractional efficiency, resistance, conditioning, or dust-loading evidence must support filter development, claims, or documentation.
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 1 frames general ventilation filter classification around ePM performance, general requirements, marking, and documentation.
AlignedISO 16890 Part 2 controls the measurement frame for fractional efficiency and air flow resistance.
AlignedISO 16890 Part 3 applies when a program needs gravimetric efficiency and air flow resistance versus captured test dust mass.
AlignedISO 16890 Part 4 addresses conditioning used to determine minimum fractional test efficiency.
AlignedISO 16890 frames general ventilation filter evaluation around particulate matter efficiency, fractional efficiency, resistance to air flow, dust loading, and conditioning effects. This Standards cluster helps teams decide when an ISO 16890-aligned plan can support filter media comparison, HVAC filter development, product claims, supplier review, or a documented basis for ePM1, ePM2.5, and ePM10 performance evidence.
Use this cluster when the core question is not only whether a filter removes particles, but whether the method, fixture, challenge aerosol, conditioning state, calculations, and report language can be reviewed against the ISO 16890 series.
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.
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.
Air filters for general ventilation - Part 1: Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM)
ISO 16890 Part 1 frames general ventilation filter classification around ePM performance, general requirements, marking, and documentation. ARE Labs uses it to align ePM1, ePM2.5, and ePM10 terminology with study design, calculation review, and report language.

Air filters for general ventilation - Part 2: Measurement of fractional efficiency and air flow resistance
ISO 16890 Part 2 controls the measurement frame for fractional efficiency and air flow resistance. ARE Labs maps it to challenge generation, sampling locations, particle measurement, pressure drop checks, and particle-size-resolved penetration or efficiency outputs.

Air filters for general ventilation - Part 3: Determination of the gravimetric efficiency and the air flow resistance versus the mass of test dust captured
ISO 16890 Part 3 applies when a program needs gravimetric efficiency and air flow resistance versus captured test dust mass. ARE Labs uses it to frame loading observations, resistance tracking, balance records, and mass-based reporting.

Air filters for general ventilation - Part 4: Conditioning method to determine the minimum fractional test efficiency
ISO 16890 Part 4 addresses conditioning used to determine minimum fractional test efficiency. ARE Labs uses it when electrostatic effects, conditioned performance, test-device limits, or conditioning records need to be visible in the protocol and report.

ARE Labs treats ISO 16890 as an aligned method family for general ventilation filter testing. The page does not claim product certification, ISO certification-body approval, or individual ISO 16890 accreditation.
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.
ARE Labs compares the product format against ISO 16890 assumptions before selecting fixture geometry, air flow, challenge aerosol, and sampling points.
Protocol setupISO 16890 Part 2 runs tie upstream and downstream particle measurements to pressure drop, background checks, sampling timing, and instrument records.
Run recordISO 16890 Part 3 programs document dust addition, captured mass context, balance records, pressure trend review, and stop conditions.
Loading logWhen ISO 16890 Part 4 is relevant, ARE Labs records conditioning state, media handling, rationale, and limits on interpretation.
Conditioning noteReports connect ISO 16890 ePM language, fractional efficiency, penetration, resistance, deviations, QC checks, and calculation workbooks.
Review-ready reportISO 16890-aligned filter work depends on defensible controls as much as the efficiency number. ARE Labs documents fixture setup, background particle levels, flow and pressure sensors, challenge stability, filter orientation, conditioning state, raw instrument files, calculations, deviations, and review records.
ISO 16890 records connect filter identification, orientation, fixture setup, flow condition, and sampling locations to the selected method frame.
ISO 16890 Part 2 studies retain particle counter or sizer files, pressure sensor records, flow meter references, and calibration status.
ISO 16890 Part 3 programs retain dust-loading observations, balance records, resistance trends, and calculation workbooks for review.
ISO 16890 Part 4 records describe conditioning state, sample handling, applicable limits, and the effect on minimum-efficiency interpretation.
ISO 17025 aligned review checks that reports state methods, deviations, uncertainty notes, and certification limits plainly.
ARE Labs connects technical topics to practical study design, method selection, controlled aerosol work, and reportable evidence without turning technical pages into sales pages.
These questions cover how filter developers, HVAC teams, and air-cleaning manufacturers decide whether work belongs under ISO 16890, an adjacent filtration standard, or a fit-for-purpose protocol. The answers identify the scoping decisions ARE Labs resolves before drafting the method, acceptance criteria, evidence records, and report package.
Q. Which part applies?
A. ISO 16890-1 frames classification, Part 2 covers fractional efficiency and resistance, Part 3 covers dust-loading behavior, and Part 4 covers conditioning for minimum fractional efficiency.
Q. Does ARE Labs certify filters?
A. No. ARE Labs performs ISO 16890-aligned testing where applicable. Certification, listing, or formal approval requires the relevant certification body or authority.
Q. Are room air cleaners included?
A. ISO 16890 publisher material excludes portable room-air cleaner elements from the direct scope. ARE Labs may still use the series as context when documenting a different protocol.
Q. What if the fixture differs?
A. ARE Labs documents deviations from ISO 16890 assumptions, including geometry, air flow, sampling location, conditioning state, and interpretation limits before reporting.
Q. What data do clients receive?
A. Typical outputs include fractional efficiency, penetration, ePM-related calculations, pressure drop, loading observations, raw data references, QC checks, plots, and documented deviations.
General ventilation filter work often overlaps with HEPA/ULPA penetration, HVAC MERV classification, room-air CADR, sorbent breakthrough, or airflow modeling questions. These neighboring clusters help route the next standards decision.
