A method includes receiving, by at least one processor, realtime data associated with airflow in a heating, ventilation, and air conditioning (HVAC) system from at least one sensor device, comparing, by the at least one processor, the realtime data from the at least one sensor device with a particular value for each sensor, operating, by the at least one processor, at least one ultraviolet C (UV-C) lamp device in the HVAC system, purifying air in the HVAC system using the at least one UV-C lamp device while confirming, by the at least one processor, that the realtime data from the at least one sensor device is within a particular threshold of each particular value for each sensor, and supplying clean, disinfected air to the airflow in the HVAC system.
