Abstract: Disclosed is a composite filter media. The composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nano fiber layer to the geometric mean diameter of fibers at the downstream face of the nano fiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

Abstract: A variable efficiency filter media. The variable efficiency filter media is a composite media formed of at least two different types of filter media, such as standard efficiency media and high efficiency media. The variable efficiency filter media has at least two different efficiency levels. The different efficiency levels can be spread across different zones. The filter media types for both the standard and high efficiency media can be spun media, melt blown media, nanofiber media, micro-glass media, cellulose media, carded staple fiber media, and the like. The variable efficiency filter media may be produced by any of an air laid or wet laid process.
