Guide to ISO 16890 air filtration standard, explaining filter classification, particle sizes, and selection based on local air quality.
This guide explains the ISO 16890 standard for air filtration, replacing EN 779. It details four new filter groups based on particle size efficiency: Grov, ePM10, ePM2.5, and ePM1. The guide helps users select appropriate filters for their environments by considering local PM10 and PM2.5 levels. It also highlights how ISO 16890 tests filters across multiple particle sizes for more realistic performance.
The guide includes practical advice on how to determine required filtration efficiency using local air quality data and provides a calculation example for reducing PM10 and PM2.5 concentrations. It also promotes MANN+HUMMEL’s eco16 filter selection system for customized, cost-effective solutions. This manual is written in Swedish.
| Filter Groups | Grov, ePM10, ePM2.5, ePM1 |
|---|---|
| Minimum Efficiency | ≥50% for each group |
| Test Particle Sizes | 0.35 µm to 8.37 µm in 12 tests |
The four new groups are Grov, ePM10, ePM2.5, and ePM1, based on efficiency in capturing particles of specific sizes.
The new ISO 16890 standard has been valid since the beginning of 2017.
The goal for the annual average value of PM10 must be less than 15 µg/m³.
The new standard tests a series of 12 different particle sizes ranging from 0,3 µm to 10 µm.
