Typical Collection Efficiency Curve with Filter Assortment Mechanisms HEPA filters are composed of a mat of randomly arranged fibers.[sixteen] The fibers are generally made up of polypropylene or fiberglass with diameters among 0.five and a pair of.0 micrometers. More often than not, these filters are made up of tangled bundles of fine fibers. These fibers produce a narrow convoluted pathway by which air passes. When the largest particles are passing by this pathway, the bundles of fibers behave just like a kitchen sieve which bodily blocks the particles from passing by means of. However, when smaller sized particles go With all the air, as being the air twists and turns, the lesser particles are not able to sustain with the movement on the air and thus they collide Together with the fibers. The smallest particles have hardly any inertia and so they constantly move across the air molecules like They're bombarded by these molecules (Brownian motion).

Last but not least, vacuum cleaner filters promoted as "HEPA-like" will commonly use a filter of an identical building to HEPA, but without the filtering efficiency. As a result of excess density of a real HEPA filter, HEPA vacuum cleaners involve additional effective motors to supply sufficient cleaning electrical power.[citation needed]

will be the mechanism by which the smallest particles are captured at lessen air velocities. As polluted air passes with the filter more info media the smallest particles go erratically or an in zig-zag sample from higher concentrated areas, this is recognized as Brownian Movement.
