ISO 16890
Overview of ISO 16890 air filter classes
The ISO 16890 standard, which replaced the previous EN779:2012 standard, provides a comprehensive classification system for air filters based on their efficiency in capturing particulate matter. This ensures that users can select filters that meet specific air quality requirements for various applications. The classification covers several categories according to particle size and filtration efficiency.
