Traditional Collection Efficiency Curve with Filter Collection Mechanisms HEPA filters are composed of a mat of randomly organized fibers.[sixteen] The fibers are typically made up of polypropylene or fiberglass with diameters among 0.5 and 2.0 micrometers. More often than not, these filters are made up of tangled bundles of wonderful fibers. These fibers produce a slender convoluted pathway by which air passes. When the largest particles are passing via this pathway, the bundles of fibers behave like a kitchen area sieve which bodily blocks the particles from passing by way of. Even so, when smaller sized particles pass Using the air, since the air twists and turns, the smaller particles can not sustain Along with the motion from the air and therefore they collide Using the fibers. The smallest particles have little or no inertia and so they constantly transfer across the air molecules like These are bombarded by these molecules (Brownian motion).
