The present application discloses an air disinfection and purification module, and an upright air conditioner. The air disinfection and purification module includes a frame, a sterilization and disinfection assembly , a guide fan, and a filter mechanism, and the overall configuration is simple. The frame is internally provided with an air treatment region, where the sterilization and disinfection assembly, the guide fan and the filter mechanism are arranged, thereby realizing a centralized purification treatment of the air entering the air disinfection and purification module, thus greatly improving purification efficiency. At the same time, since the air flowing through the filter mechanism may cause a certain loss of air volume, the configuration of the guide fan can change the airflow rate within the air treatment region, so as to compensate for the loss of air volume. The present application is used in the field of air purification devices.

An ultraviolet air sanitizer apparatus for HVAC systems has a frame defining a flow passage therethrough configured such that the frame rear is insertable into a return air inlet of the HVAC system. A sanitizer light is disposed within the flow passage. When activated, the sanitizer light emits germicidal ultraviolet light into the surrounding flow passage. A light baffle is disposed within the flow passage upstream of the sanitizer light and allows air flow but blocks light. An air pressure sensing switch is electrically connected to the sanitizing light and configured to measure air pressure differential across an air filter. When the air pressure differential is a predetermined value or greater, which is indicative of air circulation by the HVAC system, the switch turns on the sanitizer light. When the pressure differential is less than the predetermined value, the switch turns off the sanitizer light.
