Abstract:

A filter for removing mercury and other vapors from air passed therethrough includes at least one container having a plurality of cells, each cell having an inlet and an outlet oriented substantially in the direction of the flow of air passed therethrough. The cells are partially filled with disintegration-resistant activated carbon pellets to permit swirling of the pellets within the cells as air passes therethrough. The filter may also include a pre-filter made up of fibrous materials and a post-filter located downstream from the containers. In addition, a filter assembly for removing elemental and molecular contaminants and air-born bacteria from contaminated air includes a casing with a filter means inside, the cells of the filter means being partially filled with disintegration-resistant activated carbon pellets and at least one germicidal light within the casing for air disinfection as air passes through the casing. Additional filters may be included within the casing for further removal of contaminants.
