When using a fiber rod as a cigarette filter plug, it can be used as a one-material filter plug for dual or triple filters in combination with other material filter plugs to reduce the concentration of tobacco smoke passing through the fiber rod. Since the composition can be adjusted, for example, it is possible to improve the smoking taste by adding novelties such as supplying tobacco smoke with a low filtration rate or supplying ventilation air, and to add novelty to the appearance by adding novelty to the mouthpiece cross section and coloring. This makes it possible to increase the commercial value of cigarettes as a luxury item.
