Basic Assortment Efficiency Curve with Filter Selection Mechanisms HEPA filters are made up of a mat of randomly arranged fibers.[16] The fibers are usually composed of polypropylene or fiberglass with diameters among 0.five and 2.0 micrometers. More often than not, these filters are composed of tangled bundles of fantastic fibers. These fibers create a slender convoluted pathway through which air passes. When the largest particles are passing by this pathway, the bundles of fibers behave like a kitchen area sieve which bodily blocks the particles from passing by. On the other hand, when lesser particles go With all the air, since the air twists and turns, the lesser particles are unable to sustain Along with the movement on the air and therefore they collide Using the fibers. The smallest particles have little or no inertia they usually often go round the air molecules like they are bombarded by these molecules (Brownian movement).
