Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a dust collection filter enabling an ultraviolet ray to reach a wide range on the surface of a filter medium even by a few light sources; and to provide an air cleaner.SOLUTION: A dust collection filter 1 includes a filter medium 2. The filter medium 2 is constituted at least partially of fibers having ultraviolet ray diffusion means for diffusing an ultraviolet ray. As the ultraviolet ray diffusion means, fine particles having a smaller outer diameter than the outer diameter of the fibers constituting the filter medium 2 may be dispersed inside the fibers. As the ultraviolet ray diffusion means, irregularities may be formed on the surface of the fibers constituting the filter medium 2.SELECTED DRAWING: Figure 1
【課題】少ない光源でも濾材の表面の広範囲に紫外線を到達させることが可能な集塵フィルタ及び空気清浄装置を提供する。【解決手段】集塵フィルタ1は、濾材2を備える。濾材2は、紫外線を拡散させる紫外線拡散手段を有する繊維により少なくとも部分的に構成されている。紫外線拡散手段として、濾材2を構成する繊維の外径より小さい外径を有する微粒子が繊維の内部に分散していてもよい。紫外線拡散手段として、濾材2を構成する繊維の表面に凹凸が形成されていてもよい。【選択図】図1 |
