Vintage Assortment Efficiency Curve with Filter Assortment Mechanisms HEPA filters are made up of a mat of randomly organized fibers.[sixteen] 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 fantastic fibers. These fibers develop a narrow convoluted pathway by which air passes. When the largest particles are passing by means of this pathway, the bundles of fibers behave just like a kitchen sieve which bodily blocks the particles from passing by way of. Nonetheless, when smaller sized particles move with the air, as the air twists and turns, the more compact particles are not able to sustain Along with the motion of the air and thus they collide with the fibers.

Impaction; larger sized particles are struggling to prevent fibers by adhering to the curving contours from the air stream and are forced to embed in one of them instantly; this impact will increase with diminishing read more fiber separation and higher air stream velocity.
