The invention relates to the field of cigarette filters, in particular to a cigarette filter containing an ultralong TiO2 aquo-complex nanotube, TiO2 nanometer powder and activated carbon fiber. The cigarette filter contains an adsorption filtration layer, wherein the adsorption filtration layer is formed by cellulose acetate fiber, the TiO2 aquo-complex nanotub, the TiO2 nanometer powder and the activated carbon fiber. According to the cigarette filter containing the ultralong TiO2 aquo-complex nanotube, the TiO2 nanometer powder and the activated carbon fiber, the strong capacity of the TiO2 aquo-complex nanotub and the TiO2 nanometer powder on adsorbing ammonia, and the adsorption of the activated carbon fiber on tar and CO are creatively utilized, and the ultralong TiO2 aquo-complex nanotube and the activated carbon fiber can be firmly interweaved and mixed with the cellulose acetate fiber, so that the defects that in the prior art, the degradation of various components in main stream smoke of a cigarette is not obvious, and adsorbing agent is not easily interweaved and mixed with the cellulose acetate fiber are solved.
