Composite filtering structures comprising nanofibers spatially distributed between microfibers, wherein on the nanofibers and on the microfibers a palisade of protrusions of nanometric sizes in the form of nano-protrusions is produced, which palisade comprises nano-protrusions oriented with respect to the fiber surface at an angle ranging from about 70&#xb0; to about 120&#xb0;. A method of obtaining such composite filtering structures by a method that includes feeding a thermoplastic material from an extruder to at least one fiber formation die, stretching formed fibers coming out from the die, which fibers being still in a molten phase, to smaller sizes by a stream of hot air flowing tangentially to the fibers, collecting the fibers after their solidification and thus forming a mat of packed fibers providing a filtering structure, and subjecting the filtering structure to chemical etching.
