Abstract: A filter for removing multiple target molecules from a gas stream, including a three-dimensional porous support permeable to the gas stream and a first plurality of active particles for removing a first undesired molecule and a second plurality of active particles for removing a second undesired molecule, wherein the first plurality of active particles are different from the second plurality of active particle, and wherein the first and second plurality of active particles are immobilized in or by the solid support. Also, a composite filter for removing components from an airstream by trapping or conversion using a composite filter containing multiple distinct active regions with varying chemical properties with different chemical composition within the same filter.

Abstract: The present disclosure relates to a diffuser module having an inlet and an outlet for use in connection with a) an air cleaning unit having an inlet and an outlet, wherein the inlet is adapted to receive ambient air and the outlet is adapted to disperse the cleaned air, and a housing containing the air cleaning unit, b) an air cooling unit having an inlet and an outlet, wherein the inlet is adapted to receive ambient air and the outlet is adapted to disperse the cooled air, and a housing containing the air cooling unit, or c) both a) and b), wherein the inlet of the diffuser module is connected to the outlet of the air cleaning unit and/or the air cooling unit and the outlet of the diffuser module is adapted to direct the cleaned air and/or the cooled air to a specified zone.

Abstract: This invention relates to a method for cleaning air comprising one or more pollutants, the method comprising contacting the air with thermal decompositions products of ozone.
