  • Composite dual layer HEPA filter
    Publication number: 20070163218
    Abstract: The invention provides a composite, dual layer filtration material (1) having a gradient structure, comprising a dust layer (2) of wet laid dust fibers (5), a HEPA layer (3) of wet laid HEPA fibers (6) laid on top of the dust layer (2), and a transition zone (4) between dust layer (2) and HEPA layer (3) of a mixture of wet laid dust fibers (5) and wet laid HEPA fibers (6), and wherein the transition zone (4) so bonds the dust layer (2) to the HEPA layer (3) such that the composite (1) may be pleated into a pleated HEPA filtration material (30) without substantial disruption of the bond between the two layers. A corresponding process is also provided.
