Basic Selection Efficiency Curve with Filter Collection Mechanisms HEPA filters are made up of a mat of randomly organized fibers.[16] The fibers are typically made up of polypropylene or fiberglass with diameters in between 0.five and a couple of.0 micrometers. More often than not, these filters are composed of tangled bundles of good fibers. These fibers create a narrow convoluted pathway through which air passes. When the largest particles are passing via this pathway, the bundles of fibers behave just like a kitchen area sieve which bodily blocks the particles from passing by. Having said that, when lesser particles move While using the air, since the air twists and turns, the scaled-down particles can't sustain Together with the motion of the air and thus they collide with the fibers. The smallest particles have little inertia and so they generally shift across the air molecules like They may be bombarded by these molecules (Brownian motion).
