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.

A method of collecting contaminants including particulates, bacteria, pathogens, mercury and other vapors from contaminated gas, said method comprising: attaching a filter assembly to a heating, ventilating and air conditioning system so that air being recirculated through the system flows through the assembly, said filter assembly having at least one container including a plurality of cells partially filled with activated carbon pellets adapted to swirl when gas flows therethrough and at least one germicidal lamp; and flowing contaminated gas from an upstream position to a downstream position though the filter, thereby swirling the pellets contained therein, and eventually exposing substantially all of the surface of the pellets to the contaminated gas to effect removal of the contaminants by the filter.
