More often than not, these filters are made up of tangled bundles of great fibers. These fibers make a narrow convoluted pathway through which air passes. When the biggest particles are passing by this pathway, the bundles of fibers behave like a kitchen sieve which bodily blocks the particles from passing as a result of. Nevertheless, when more compact particles move Using the air, as the air twists and turns, the smaller sized particles are not able to sustain While using the motion on the air and so they collide with the fibers. The smallest particles have little or no inertia and they constantly go round the air molecules like They're bombarded by these molecules (Brownian motion).

It had been known as an "absolute" air filter and laid the groundwork for even further analysis to come back in building the HEPA filter.[38]
To find out just what the randomly aligned mat of fibers seems like, listed here’s a closeup of the HEPA filter Wise Air helps make for that Sqair air purifier, and then alongside it a perspective at the nano-level with the help of the microscope.
Laws made by EPA, OSHA, CDC and various federal, point out and local governing administration organizations responsible for human health and fitness and IAQ concerns specify HEPA filters for asbestos, lead and mildew abatement, TB and SARS isolation rooms and healthcare renovation projects.
