Particulate air filters for general ventilation — Determination of the filtration performance
ISO 21220:2008 refers to particulate air filters for general ventilation. It describes testing methods and the test rig for measuring filter performance. The test rig is designed for an air flow rate between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min).
ISO 21220:2008 applies to air filters having an initial efficiency of less than 99 % with respect to 0,4 �m…
