Air filters for general ventilation - Part 1: Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM) (ISO/DIS 16890-1:2025)
ISO 16890-1:2016 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4.
The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24 inch × 24 inch).
ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % when tested according to the procedures defined within ISO 16890‑1, ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4. Air filter elements with a higher initial efficiency are evaluated by other applicable test methods (see ISO 29463-1, ISO 29463-2, ISO 29463-3, ISO 29463-4 and ISO 29463-5).
Filter elements used in portable room-air cleaners are excluded from the scope of this part of ISO 16890.
The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in Annex A.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Introduction
The effects of particulate matter (PM) on human health have been extensively studied in the past decades.
The results are that fine dust can be a serious health hazard, contributing to or even causing respiratory
and cardiovascular diseases. For the outdoor environment, the U.S. Environmental Protection Agency (EPA),
the World Health Organization (WHO), the European Union, and other national agencies have established
acceptable air quality standards according to concentrations of particulate matter classified per their
aerodynamic sizes, defined as PM2,5 and PM10, and measured according to strict prescriptive methods and
sampling times.
Since there is growing interest in relating indoor air quality to outdoors, ISO 16890 series of standards
classifies ventilation filters according to their efficiencies measured with an optical diameter between
0,3 µm and x µm and relating the result to historic global average ambient PM concentrations. Although not
exactly equivalent to filter performance at national ambient air quality standards at PM, the classification
scheme presented in the standards will yield a level correspondence to the effectiveness of the filter for
ambient particle concentrations. It is however recognized that the correspondence based on global averages
may not be exactly the same at a specific location s
