1. An air filtration system for filtering airborne contaminants from air, the system comprising:
a panel structure comprising a plurality of individual and interchangeable filtering modules arranged in an array with each module adjacent and in contact with at least one other module, and each module comprising: an external wall defining an internal cavity therein, the external wall comprising: a first face comprising at least one opening into the internal cavity configured for permitting plant growth therethrough, and a second face opposite the first face, with the internal cavity located between the first face and the second face, a first side portion extending from the first face to the second face; and a second side portion extending from the first face to the second face, with the second side portion being opposite the first side portion, wherein the second face comprises an integral ventilator tube formed as a portion of the second face and extending along the second face from the first side portion to the second side portion, the ventilator tube having a first air interface at the first side portion, a second air interface at the second side portion, and a plurality of perforations, wherein each of the first and second air interfaces forms a substantially airtight seal and is configured to align with a first and second air interface of a ventilator tube of an adjacent module to form an airflow channel extending along the array, wherein the plurality of perforations are configured to provide a distributed air interface from the ventilator tube to an organic biofilter medium, the organic biofilter medium within the internal cavity, the organic biofilter medium comprising a microbial colony configured to biologically degrade airborne contaminants, and having a depth extending in a direction from the first face to the second face, and a plant rooted in the organic biofilter medium and growing through the opening in the first face, wherein the organic biofilter medium is configured to serve as a growth base for both the plant and the microbial colony; and an air-distribution network configured to pass air to be filtered into the airflow channel, into the internal cavity adjacent the second face, through the organic biofilter medium, and out of the internal cavity through the at least one opening in the first face to contact the air to be filtered with the microbial colony, wherein a first air interface for at least one module is connected to a flow control device. |
