Abstract
Fiber structures and methods are described that incorporate a body of a micron fiber modified by the attachment of discrete length, crimped nano-fibers. Numerous of these modified fiber structures can be assembled into air filter media. Further augmentations of the modified fibers and media can be implemented to improve filtration characteristics.
