An object of the present invention is to provide a fiber filter capable of improving the strength of the photocatalyst layer and an air cleaner using the fiber filter. Therefore, the titanium dioxide particles 2 are placed on the fiber filter main body 1 composed of aluminum fibers having a diameter of 50 µm to 500 µm, a neck portion of 500 g / m 2 to 10000 g / m 2, and a porosity of 50% to 90%. By spraying, a titanium dioxide film having anatase crystal structure of 70% by mass or more is formed. |
