Abstract

The present invention provides for a system for disinfecting air circulated in an HVAC system. The system includes an interchangeable filter located in a filter housing. The filter housing connects two segments of ductwork. The filter housing is contoured to align with perimeter dimensions of each of said two segments of ductwork. The filter housing defining a four-walled metallic segment with openings correlating to each of said two segments of ductwork. A closeable opening provides for insertion of the interchangeable filter therein created by a hinge moveably coupling one wall of said four-walled metallic segment thereby creating a hinged flap, whereby once closed, the flap seals an inside airflow channel between each ductwork segment connected by said four-walled metallic segment.

Claims (8)

1 . A system for disinfecting air circulated in an HVAC system, comprising:

an interchangeable filter located in a filter housing, wherein said filter housing connects two segments of ductwork and said filter housing is contoured to align with perimeter dimensions of each of said two segments of ductwork;

said filter housing defining a four-walled metallic segment with openings correlating to each of said two segments of ductwork;

a closeable opening for insertion of said interchangeable filter therein created by a hinge moveably coupling one wall of said four-walled metallic segment thereby creating a hinged flap, said hinge being positioned along a top edge of said four-walled metallic segment and being affixed between said hinged flap and said four-walled metallic segment such that said hinged flap remains attached to said filter housing when opened and rotates about a fixed rotational axis extending along said top edge, whereby once closed, said flap seals an inside airflow channel between each ductwork segment connected by said four-walled metallic segment;

wherein said interchangeable filter is an ultraviolet light filter with ultraviolet lights configured in a ring formation affixed to a removable frame within an inner perimeter of said filter housing, wherein said ultraviolet lights are mounted along a width and a height of said frame and are positioned along a perimeter of said removable frame and directed inward toward an airflow passage defined through said filter housing such that ultraviolet light projects across said airflow passage on both an upstream side and a downstream side of said removable frame;

wherein said hinged flap includes a power aperture formed therethrough;

wherein an electrical inlet is mounted through said hinged flap; and

wherein said removable frame includes an electrical connector positioned to electrically couple with said electrical inlet when said hinged flap is in a closed position.
