Abstract
A filter includes resin particles and photocatalyst particles having absorption at wavelengths of 450 nm and 750 nm in the visible absorption spectrum. The photocatalyst particles have a high photocatalytic function and are present on the surface of the resin particle. The filter is air permeable, transmits visible light, and has high deodorizing performance.
Claims17
A filter comprising:
- resin particles;
- photocatalyst particles having absorption at wavelengths of 450 nm and 750 nm in a visible absorption spectrum, wherein the photocatalyst particles are present on a surface of each resin particle, and at least a portion of a surface of each of the photocatalyst particles is attached to an organometallic compound, and
- a holding member that holds the photocatalyst-attached resin particles inside, the holding member being a bag-shaped member or a box-shaped member.
