Industry Standards Compliance
The air filtration industry follows various standards for classifying and evaluating filter performance. In the United States, ASHRAE has established test standards since 1968, recognized by ANSI as the benchmark for filter classification.
European standards reference ASHRAE, with CEN releasing the EN 779 standard in 2012 (revised in 2012) which defined minimum filtration efficiency (ME) for F7-F9 efficiency filters, ensuring better air quality at AHU outlets.
The 2016 introduction of ISO 16890 standard enabled global standardization in air filtration, replacing regional standards ASHRAE 52.2 and EN779:2012.
