Classic Collection Efficiency Curve with Filter Collection Mechanisms HEPA filters are composed of a mat of randomly organized fibers.[sixteen] The fibers are generally made up of polypropylene or fiberglass with diameters concerning 0.5 and a couple of.0 micrometers. More often than not, these filters are made up of tangled bundles of wonderful fibers. These fibers create a slender convoluted pathway through which air passes. When the largest particles are passing by way of this pathway, the bundles of fibers behave like a kitchen area sieve which physically blocks the particles from passing by way of. Nevertheless, when more compact particles move With all the air, as the air twists and turns, the more compact particles can't keep up While using the motion from the air and so they collide Together with the fibers. The smallest particles have very little inertia they usually normally transfer within the air molecules like they are bombarded by these molecules (Brownian motion).

HEPA filters obstruct the airstream in vacuum cleaners: it will take quite a lot of suction to pull air previous all Individuals convoluted fibers.

HEPA is definitely an acronym that means High Efficiency Particulate Air. The Nationwide Air Filtration Association (NAFA) defines HEPA filters as being a filter possessing a minimum efficiency of ninety nine.97% on 0.three micrometer particles. HEPA filter’s paper media is composed of micro-glass fibers, artificial fibers, or expanded film like polytetrafluoroethylene (PTFE) which are pleated forwards and backwards like an accordion to form a tight and compact filter component with a big floor spot. This limited pleating is needed as the paper incorporates a high resistance to airflow plus the media velocity is often during the range of six fpm (.03 m/s). HEPA filters do the job by forcing air through the media’s good mesh or “net” that traps unsafe particles like pm2.
Once you hear HEPA filters pointed out, these are definitely "true." The only purpose this name, in particular, exists is because of the confusion brought on by These "HEPA-like" and comparable names produced by advertising and marketing teams.
Impaction — Larger particles can’t Stick to the curve check here of airflow in the filter and embed inside the fibers
