Claim 13:
14. A system for processing air for the removal of pathogens, the system comprising:
a housing having an air inlet for receiving contaminated air to be processed and a discharge air outlet for discharging processed air;
a delay chamber having an inlet and an outlet, the delay chamber comprising RF transparent material forming a labyrinth of alternating passages, the delay chamber arranged within the housing between the air inlet and discharge air outlet, wherein the delay chamber forms a faraday cage operative to contain microwave radiation within the delay chamber;
a first magnetron adjacent the inlet of the delay chamber and a second magnetron adjacent the outlet of the delay chamber, the first and second magnetrons generating microwave radiation directed into the labyrinth of the delay chamber;
a first UVC energy source within a first port between the air inlet of the housing and the inlet of the delay chamber for exposing contaminated air to UVC energy before passing through the delay chamber;
a second UVC energy source within a second port between the outlet of the delay chamber and the discharge air outlet of the housing for exposing air exiting from the delay chamber to UVC energy before exiting the housing through the discharge air outlet, wherein the first and second UVC energy sources each comprise a 265 nm UVC led source;
a first particle filter adjacent the air inlet of the housing and a second particle filter adjacent the discharge outlet of the housing, wherein at least one of the particle filters comprises a HEPA filter;
a microwave shielding screen adjacent the inlet and outlet of the delay chamber; and
a blower adjacent the discharge air outlet of the housing.
