Especially smokers of filterless cigarettes or blunts prefer to use filter tips with their home-rolled cigars. They prevent bits of tobacco from entering the mouth and keep the end of the cigarette cool to prevent a burning of lips and fingers.
Filter Tips are bits of cardboard used by most cigarette rollers. They are not filters per se as no part of the smoke gets filtered but fullfill the other mentioned purposes like stopping tabac from mating with the lips, the fingers from burning and - last but not least: Cigarettes without filter/filter tips are quite a waste, as one end can't be smoked and has to get dumped.
