Collecting a gaseous pollutant from air

A system for filtering a gaseous pollutant from an enclosed area, the system comprising:

• one or more air filtration systems, wherein individual ones of the filtration systems comprise:
• a duct having a duct inlet in fluid communication with air from the enclosed area;
• an inlet manifold comprising one or more manifold portions in fluid communication with the duct;
• and
• a panel-bed assembly comprising one or more panel-bed chambers, the respective panel-bed chambers comprising one or more panel-beds comprising a solid sorbent for filtering the gaseous pollutant, wherein the one or more manifold portions distribute the air to the one or more panel-bed chambers.

A method for filtering a gaseous pollutant from air within an enclosed area, comprising:

• providing a panel-bed assembly comprising one or more panel-bed chambers, the respective panel-bed chambers comprising one or more panel-beds containing a solid sorbent;
• providing an inlet manifold comprising one or more manifold portions separately in fluid communication with the one or more panel-bed chambers;
• filtering air by passing the air through the inlet manifold to distribute the air to the oner or more panel-bed chambers for contact with the solid sorbent;
• and
• passing the filtered air through an outlet manifold to exit the panel-bed assembly.
