Abstract
Official abstract text for this publication.
Filter media and filters are provided that include at least two layers and a plurality of nanoparticles dispersed in depth within at least one of the layers. A gas filter comprises a first layer of fibers, a second layer of fibers bonded to the first layer and a plurality of nanoparticles incorporated into the first layer. The nanoparticles increase the overall surface area within the filter, which increases its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop (i.e., air flow) through the filter. In addition, the filters disclosed herein are capable of withstanding rigorous conditioning, which allows the filter to achieve the same level of filtration performance throughout the lifetime of the filter. Systems, devices and methods are also provided for manufacturing such filters.
First claim
Opening claim text (preview).
What is claimed is: 1 . A filter media comprising: a first layer of fibers having a first surface and a second opposing surface; a second layer of fibers adjacent the first layer of fibers; and a plurality of nanoparticles incorporated into the first layer of fibers from the first surface to at least a midpoint between the first surface and the second opposing surface. 2 . The filter media of claim 1 , wherein the nanoparticles are incorporated subst…
