Abstract
A present invention is directed to a laminated filtration media comprising a nanofiber coating applied onto a synthetic substrate. Generally, the laminated filtration media can be produced by applying the nanofiber layer onto the synthetic substrate via an electrospinning process and then thermo-mechanically bonding the nanofiber layer onto the synthetic substrate via a thermal bonding process. The laminated filtration media exhibits superior durability and can be used in a wide array of air filtration applications.
