Abstract

A filter (1) which is an antifouling filter for ventilators or cooking range hoods. The filter (1) comprises a fibrous sheet including fibers having a fiber diameter of 5 to 35 µm, excluding 35 µm. The surface of the fibers is oil-repellent. Also provided is a layered filter (10) which comprises a collection layer (11) made of the filter (1) and a space formation layer (12). The layered filter (10) is used so that the space formation layer (12) is located downstream from the fluid inhalation side. The space formation layer (12) is constituted of a material and has a filling factor, which is the proportion (%) of the volume of the constituent material to the apparent volume of the space formation layer (12), of 1-7% under a load of 0.3 kPa, and has a thickness as measured under the same load of 1-12 mm. The collection layer (11) is made of a nonwoven fabric having a fiber diameter of 7 to 35 µm, excluding 35 µm.
