<p>An air purification filter that is used together with another filter, prevents scatter of cut pieces of fibers separated from the another filter, and effectively reinforces the another filter. The air purification filter (2) has a fiber array layer body formed by layering fiber array layers over each other, where, in each of the fiber array layers, continuous long fibers are substantially linearly arranged aligned in one direction. The air purification filter (2) is adapted to be placed closer to a space (10) to be air conditioned than the another air purification filter (1) placed at an air outlet of an air conditioning facility. In the fiber array layers, some fiber array layers and the remaining fiber array layers are layered over each other such that the directions of extension of the fibers of the some and remaining fiber array layers are different.</p> |
