Composed of a mat of randomly arranged fibers which typically composed of fiberglass and possess diameters between 0.5 and 2.0 micrometers, HEPA filters, unlike membrane filters at this pore size, where particles as wide as the largest opening or distance between fibers cannot pass in between them at all, are designed to target much smaller pollutants and particles.
