Classic Selection Efficiency Curve with Filter Selection Mechanisms HEPA filters are composed of a mat of randomly arranged fibers.[sixteen] The fibers are generally made up of polypropylene or fiberglass with diameters involving 0.five and 2.0 micrometers. More often than not, these filters are made up of tangled bundles of high-quality fibers. These fibers produce a slender convoluted pathway by which air passes. When the most important particles are passing by means of this pathway, the bundles of fibers behave similar to a kitchen sieve which bodily blocks the particles from passing through.
