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.

A coalescer has variable characteristics including variable diameter of individual fibers along their length such that an individual fiber has differing diameters at different points along its length, and including variable porosity.
