Basic Assortment Efficiency Curve with Filter Collection Mechanisms HEPA filters are made up of a mat of randomly arranged fibers.[sixteen] The fibers are usually composed of polypropylene or fiberglass with diameters involving 0.5 and a couple of.0 micrometers. More often than not, these filters are composed of tangled bundles of high-quality fibers. These fibers create a slender convoluted pathway through which air passes. When the largest particles are passing through this pathway, the bundles of fibers behave just like a kitchen sieve which physically blocks the particles from passing by. Even so, when smaller sized particles go With all the air, as the air twists and turns, the more compact particles are not able to sustain with the motion on the air and thus they collide Using the fibers. The smallest particles have very little inertia plus they constantly shift round the air molecules like They may be bombarded by these molecules (Brownian motion).
