Air Reactivator

An air reactivator includes a plurality of first ribs, a plurality of second ribs, a plurality of diffusion members, and a plurality of air passages. Each of the first ribs has a first top face and a first bottom face and two first inclined faces. Each of the second ribs has a second top face and a second bottom face and two second inclined faces. The diffusion members are defined at connections of the first ribs and the second ribs. Each of the diffusion members has a projection and a third bottom face and a recessed portion. Each of the air passages is defined between the first inclined face, the second inclined face, and the recessed portion. The first ribs, the second ribs, and the diffusion members are made of a mixture of far infrared material and polymer material.
