In the world of filtration, we differentiate filters and measure their performance using various testing methods, otherwise known as multi-pass testing. In order to understand the testing process, we've created two videos that cover how filters are tested. In the video below, we'll cover four different methods of testing: ISO 16889, which is the industry standard test; ISO/CD 23369 Cyclic Flow Test, which is proposed to replace the current industry standard test; The Cyclic Stabilization Test; and Hy-Pro’s Dynamic Filter Efficiency Test.
